2015, 12-01 Study Session MINUTES SPOKANE VALLEY CITY COUNCIL REGULAR MEETING STUDY SESSION FORMAT Spokane Valley City Hall Council Chambers Spokane Valley,Washington December 1,2015 6:00 p.m. Attendance: Councilmembers Staff Dean Grafos, Mayor Mike Jackson, City Manager Arne Woodard,Deputy Mayor Mark Calhoun, Deputy City Manager Chuck Hafner, Councilmember Cary Driskell, City Attorney Rod Higgins, Councilmember Erik Lamb, Deputy City Attorney Ed Pace, Councilmember Chelsie Taylor, Finance Director Ben Wick, Councilmember John Hohman, Community Development Dir. Bill Gothmann,Councilmember Pro Tern Mike Stone, Parks &Recreation Director Eric Guth, Public Works Director Lori Barlow, Senior Planner Marty Palaniuk, Planner John Pietro,Administrative Analyst Sean Messner,Traffic Engineer Carolbelle Branch, Public Information Officer Rick VanLeuven, Police Chief Chris Bainbridge, City Clerk Mayor Grafos called the meeting to order at 6:00 p.m. ROLL CALL: City Clerk Bainbridge called the roll; all Councilmembers were present. ACTION ITEMS: 1. Second Reading Proposed Ordinance 15-023 Adopting Moratorium Extension and Findings—Erik Lamb After City Clerk Bainbridge read the ordinance title,it was moved by Deputy Mayor Woodard and seconded to approve Ordinance No. 15-023 adopting a renewal and extension of the moratorium on unlicensed marijuana uses for a period of six months and adopting related findings of fact.After Deputy City Attorney Lamb briefly went over the purpose of the extension and renewal, Mayor Grafos invited public comment. Jason Dixon, of Otis Orchards: his prepared statement was distributed to Council; he read from that statement explaining that he owns Herb Nerds shop in our city; said his medical dispensary is one of only three in Spokane Valley which meets the sales tax remittances requirements for the 502 merger;that since the recreation shops have opened, sales in medical dropped significantly, from $17,000 a month to $3,400 a month; said the State provides opportunity to merge into a unified system and this merger is their only hope;said the three shops which urgently need to merge are his,Alternatives MD,and E.K.Green;that this would put the valley at six recreational shops and said"isn't that a nice agreeing to meet in the middle by providing at least this much cooperation for these three medical dispensaries to survive." There were no further public comments. Vote by Acclamation:In Favor: Unanimous. Opposed:None. Motion carried. NON-ACTION ITEMS: 2. Chamber of Commerce `BIG 5' —Katherine Morgan Via her PowerPoint slides,Ms. Morgan went through the history leading up to this BIG 5; she outlined the 5 goals as Greater Outdoors, Greater Goods, Greater Learning, Greater Cures, and Greater Vision. Ms. Morgan explained that now is the time to put action behind the goals;she mentioned the upcoming meeting this Thursday where they will be identifying strategies and action goals, and discuss how to achieve those Council Study Session: 12-01-2015 Page 1 of 5 Approved by Council:01-05-2016 goals and celebrate those great strengths.Council thanked Ms.Morgan for her presentation. As a means to show support, Councilmember Wick suggested bringing forth a resolution of support to formally endorse these BIG 5 goals. Other members of Council concurred. 3. Proposed Fee Resolution for 2016—Chelsie Taylor Ms.Taylor explained the process and purpose of the Fee Resolution; said there have been no changes since 2014; and she explained about the proposed changes from Parks and Recreation, and Community and Economic Development, as noted in her December 1, 2015 Request for Council Action. Ms. Taylor also mentioned that the third bulleted item should really state for Edgecliff Park shelter and Sullivan Park Shelter, not Brown's Park shelter. There was some discussion about the false alarm fees and the overall program, and Mr. Jackson said Council could always adjust rates later if they desired, and that a future discussion could look at cost recovery. Councilmember Hafner asked how many false alarms are received, and Ms. Taylor said she would have to research that. It was agreed this item would come to Council for approval consideration at the December 15 council meeting. 4. Community Minded TV Agreement—John Pietro In response to the previous question about number of false alarms, Mr. Pietro said there are between 600 and 900 false alarms per year. Moving to the Community Minded TV(CMTV)Agreement,Mr.Pietro said that this agreement expires the end of this year; he mentioned that the expiration date will change to match that of the Cable Franchise,which is February 10,2020. Mr. Pietro explained some of the history of PEG (Public Education and Government) fees and public access channels. He also mentioned that CMTV and the Spokane County Library District are developing an agreement where CMTV would make video equipment available to the library so that it could develop a studio/media lab at the Valley Branch for producing community content features, and said staff anticipated recommending at a later date, that additional appropriations from the PEG fund be made available to CMTV to support those efforts. Councilmember Pace asked about the public having the ability to watch meetings live instead of on Thursdays, and Mr. Pietro said that would likely require is to have our own channel,which would involve a lot of operational cost,adding that staff is looking into available options,and he mentioned that the public now has the option of watching live via Internet.In response to a question from Councilmember Wick about the library owning the cameras,Mr.Jackson said that the initial conversation started with the library as they wanted to provide this service opportunity to citizens; he said we contacted the schools several times but they don't offer broadcasting as part of their curriculum, and the library showed an interest. City Attorney Driskell added that in terms of PEG,we already have an existing agreement with CMTV as a public entity, so it would be a clean path for us to accomplish this; adding if we had our own station/equipment, that would also require us to have staff with expertise in running, managing, and repairing the equipment, but with CMTV as the primary responsible entity, this would accomplish the goal to make the equipment available to the public. Deputy Mayor Woodard asked about the PEG fund and Mr. Pietro said we initially had about$100,000 and have about 350,000 in that fund now which can be used for equipment in the new city hall. Mr.Jackson added that there are constraints on how we use those funds. 5. Hauling Uncovered Loads—Erik Lamb Deputy City Attorney Lamb explained that these proposed regulations stem from a state law requirement for any city with a transfer station, making it unlawful for persons to haul uncovered or unsecured loads; and since we now have our own solid waste system, we are required to adopt this provision as a means to prevent littering and promote traffic safety. Mr. Lamb said the regulations allow a fee to be imposed at the transfer station, which can be set by the local jurisdiction, and it could be a civil infraction or a misdemeanor, and suggested it be high enough to be a disincentive to not securing or covering loads. Mr. Lamb said the City of Spokane does not impose a penalty, but Cheney does. There was some discussion about enforcement, and how other entities handle this, and it was determined that Mr. Lamb will research what other cities do, including the process, fee, and enforcement. Council Study Session: 12-01-2015 Page 2 of 5 Approved by Council:01-05-2016 Mayor Grafos called for a recess at 6:50 p.m.; he convened the meeting at 7:02 p.m. 6. Street Maintenance Contact Renewal—Eric Guth Public Works Director Guth said that this option would be the first of four option renewal years; said the hourly labor rates will changes as noted in the documentation, but we are not proposing an increase in the total contract amount, as the labor increase would be absorbed through changes in the work plan. Council agreed for staff to bring this back next for a motion consideration. 7. Street Sweeping Contract Renewal—Eric Guth Mr. Guth said this is a companion item to the previous item; that this is considered a service so it is an hourly contract; said this allows us to negotiate any changes in hourly rates; that we tied it to the CPI-U (All Urban Consumers Price Index) or a maximum of 3%; said this cannot exceed 3% in any given year, and the CPI-U levels remained level likely attributable to low fuel costs. Council agreed for staff to bring this back next for a motion consideration. 8. Spokane Regional Transportation Management Center Interlocal Agreement—Eric Guth, Sean Messner Traffic Engineer Messner went over the background of the proposed Amendment 2, which he said would get us through the end of 2017 with minimal impact to the budget; and if Council agrees, he would like to bring this back next week for a motion consideration. Councilmember Pace asked what this was used for last year and Mr. Messner replied "very little." Mr. Messner said that 97% of this use is for incidents on WSDOT's (Washington State Department of Transportation) facilities, and perhaps we have .03%; said two operators sit in front of a wall of TVs and routinely go through them and respond to radio calls from the Washington State Patrol or other law enforcement, and to citizen calls, and in which case, they would contact that jurisdiction to let them know of an incident.Mr.Messner said that all traffic signals are funneled back to them before they come to the City, but that process will change after this year as we would have control of our own traffic signals;said the public generally uses it for the regional cameras on I-90,Division, and other main roads. Mr. Messner said the benefit of staying with this is having one stop for all regional cameras and that it does benefit the traveling public, but there isn't much benefit from a City staff point. After discussion about the pros and cons and uses of SRTMC, it was determined to stay with this through next year since there is no cost, and to evaluate it again prior to year's end. 9. Shoreline Master Program Final Adoption—Lori Barlow Ms. Barlow went over the process to finalize our Shoreline Master Program (SMP), all as noted on her December 1, 2015 Request for Council Action. Ms. Barlow also noted that the Department of Ecology unconditionally approved our document, which doesn't occur often, and said we have received a lot of praise on the document and its development as well as the ways we have developed our regulations. There was Council consensus to bring the documents back for approval consideration at the next Council meeting. 10. Spokane Valley Municipal Code Text Amendments—Marty Palaniuk Planner Palaniuk explained that because of adopting the Shoreline Master Program and the Department of Ecology's approval,we need to correct certain inconsistencies within our Municipal Code,and he explained the needed modifications. There was Council consensus to bring the documents back for ordinance first reading at the next Council meeting. 11. Comprehensive Plan Legislative Review—John Hohman, Lori Barlow Community and Economic Development Director Hohman said that staff continues working on the four chapters not dependent on the population allocation number, i.e. Utilities, Environment,Parks, and Capital Facilities; said they also looked at the water supply situation and in past years did a general review of all the water districts and water supply, although they didn't get into too much detail; said they are looking at coming up with a lot more detail in order to better understand the future as it concerns water supply. Mr. Hohman also noted that staff is working on a scope of work for the next phase of the comp plan update with Council Study Session: 12-01-2015 Page 3 of 5 Approved by Council:01-05-2016 the consultant, to include going through each chapter to determine what will be handled by staff or by the consultant and said they hope to have that ready soon. Mr. Hohman stated that at the November 4 meeting of the Steering Committee of Elected Officials, they decided to forward the PTAC (Planning Technical Advisory Committee) recommendations to the Board of County Commissioners for their evaluation and process; said there was a lot of discussion and questions from the Commissioners, and said he is unsure what direction the Commission will take; but there is a great desire to move forward on the process so we are actively looking at options in that regard. In response to Councilmember Hafner's question about the reason for the Commissioners' opposition to the number, Mr. Hohman said it is his understanding the Commissioners felt the overall number was too low and that it should be more reflective of the number they generated back in 2013;he said PTAC's recommendation was 580,000 and the County's number was closer to 618,000. Mr.Hohman said that Mr.Dave Anderson of Commerce helped put that methodology together and it has tracked well over the years with allocation number and actual growth. Mayor Grafos concurred and said that Commerce went back about fifteen years and discovered their projections tracked very closely with the population allocations of PTAC. Mr. Hohman said if we were to proceed under the numbers we like and the County disagrees, we would be looking at some risk. 12. City Hall Update—John Hohman Mr. Hohman had City Clerk Bainbridge distribute copies of the "Energy Life Cycle Cost Analysis for Spokane Valley City Hall" which was prepared by MSI Engineers. Mr. Hohman said if Council desires, we could bring in an engineer at the next study session who would be prepared to answer any questions concerning the recommended alternatives for a HVAC system; said this particular system mentioned in the cost analysis was developed in the 1980's in Japan and about 50% of office buildings of our size range in Japan use that; and it has been used in Europe as well and is started to be used more in the United States. Mr. Hohman said the costs are dropping and more manufacturers are using this system, and that several new buildings have been constructed with this in the Pacific Northwest, and appears to be a very good system, although staff still has some vetting to do. Mayor Grafos said he has one in his building and would like to hear more, and Councilmember Pace said he would also like to see an overall summary of how the purchase costs would affect the budget.Concerning the use of river rock on the outside of the building, Mr. Hohman said the architect is still looking into potential options, and that the cost per square foot is about $35.50 for river rock, $12.40 for brick, and $11.35 for block, and said he would ask Mr. Roth to bring in more information and have him develop some concepts for Council's consideration. 13. Advance Agenda—Mayor Grafos Councilmember Pack asked about the Blake sidewalk project and Mr. Jackson replied that he met with Public Works staff and they are putting together a program for public input, after which we can place that matter back on an agenda. Councilmember Wick mentioned an important upcoming vote with SRTC (Spokane Regional Transportation Council), and he mentioned the idea of having a method that this body could assign a delegate who could serve until the re-appointment next year; said they will be working on a study on grade separation projects and prioritizing funding;that the Puget Sound region did a study on how they prioritized all grade separations,but we have not done a study and said he feels that vote will likely be in January or February, and he mentioned the idea of being an alternate at that January meeting;mentioned the idea of sending a letter to SRTC that we have identified the grade prioritization and relate back to their 2040 Plan; and to put forward our recommendation that there has been a prioritization of projects, and to carry that message through with a letter to SRTC. Council concurred. Councilmember Hafner asked about historic preservation,and Mr.Jackson said he will work with staff to bring that back to an upcoming agenda. 14. Department Monthly Reports These reports were for information only and were not discussed or reported. Council Study Session: 12-01-2015 Page 4 of 5 Approved by Council:01-05-2016 15. Council Comments-Mayor Grafos Councilmember Hafner reported that Councilmember Bill Bates is doing better than anticipated; he is off the oxygen and the x-rays show the cancer is in remission and no longer spreading elsewhere. 16. City Manager Comments-Mike Jackson Mr. Jackson spoke concerning the November 17 windstorm and the resulting damage; said he would like to get Council consensus for staff to balance the budget using the funds from the winter weather reserve to pay for some of these items; said there is a potential for federal reimbursement,and we need to spend funds now and in the near future to pay for the cleanup; said there were numerous fallen trees, damage to signs and signs and debris in roadways; that street sweeping will be a large component of these expenses; said Public Works continues to find a few trees leaning or down so there is additional cleanup; said there were 95 different locations in the city where trees were removed, and we had Senske and Geiger crews working to help; said the tree removal component is about $108,000, and again he recommended using winter weather reserves; and said we will want to replenish that back up to $500,000. Mr. Jackson said of our 88 traffic signals, 30 went down but are all back up and working; some signs were damaged and had to be replaced for an estimated cost of$5,000; said our parks also suffered with 35 to 40 large trees being blown down in Castle Park,Edgecliff,Sullivan,Terrace View and Mission Parks,and we are working with Senske and logging companies to fill the holes in the ground, at an estimated cost of$165,000. Mr. Jackson also noted that Sunshine Disposal has agreed to take all tree debris, no matter what size, all for the same clean green cost;and said they processed about 540 tons of organic materials. All total,Mr.Jackson said the cost was approximately$300,000; and Council concurred to bring this back for a motion at next week's council meeting. Mr. Jackson also noted that Christmas Eve is on a Thursday, and that it is normally a very quiet day, and with Council's approval,he asked about considering closing at noon on Christmas Eve. Council concurred; and Mr. Jackson said a motion to that effect would also be on next week's agenda. 17. Executive Session: Performance Review of a Public Employee It was moved by Deputy Mayor Woodard, seconded and unanimously agreed to adjourn into executive session for approximately sixty minutes to review the performance of a public employee, and that no action would be taken upon return to open session. Council adjourned into executive session at 8:10 p.m. At approximately 9:12 p.m., Deputy Mayor Woodard returned to Council chambers and announced that the executive session would be extended for ten minutes. At approximately 9:22 p.m., Mayor Grafos declared Council out of executive session, at which time it was immediately moved by Deputy Mayor Woodard, seconded, and unanimously agreed to adjourn. 1 1 if r L.R.

''' ristine Bainbridge, City Clerk in�- Council Study Session: 12-01-2015 Page 5 of 5 Approved by Council:01-05-2016 Herb Nerds is situated between Latah Creek Winery(Catering to patrons 21 or older) and a very popular store Zanies which(caters to patrons 18 or older).There are no schools near by,we are heavily invested into this location,as we've felt it to be extremely appropriate for this particular type of business, especially considering the Merger of medical and recreational.This"Herb Nerds" medical dispensary is one of only 3 in the Spokane Valley who meet the sales tax remittance requirements for the 502 merger. Med shops Rec Shops Knowledge,effects, useage information hurry up and buy(no advice allowed) Can only sell to 0.001%of population Can sell to 100.00%of population $17,000.00 dropping to$3,000.00/mo $100,000's and growing Very poor and struggling Very rich and powerful,able to oppress Can not afford the lawyers and crafty tactics! Financial ability to oppress medical ! State provides opportunity to MERGE into a unified system! Since the rec shops have begun to open, sales in medical,already only able to sell to .001%of the population(Dr's Recomendation Holders) have been crushed,and I'm willing to cite a figure from my shop Herb Nerds, our sales have dropped from $17k per month all the way down to$3.4k,a crushing blow,and this merger is our only hope. SINCE REC SHOPS HAVE OPENED! Med Shops Rec Shops Sales have fallen from$17k/mo to$3.4k/mo! Rec shop sales soaring near 7 digits,some of them We are just trying to survive&stay open. Rec shops getting rich and dangerously powerful Trying to participate in the merger Trying to prevent others from participating ALL THE SUDDEN: Moratoriums galore, location prohibitions getting extended,limitations on how many shops,well mind you, .. When the shops in the Valley were limited to 3 recreationals,there was 7 medical dispensaries at the time for a total of 10 shops. Now the rec shops of course are pushing this agenda to maintain it at 3 when in all reality it was accepted at 10 in all this time past.So isn't it a nice MERGER to allow the 3 shops paying sales taxes to merge into the system without all of these road blocks. From all I can tell those three shops who urgently need to merge are: Herb Nerds,Alternatives MD, and E.K. Green.This would put the valley at 6 recreational shops and isn't that a nice 'agreeing to meet in the middle', by providing at least this much cooperation for these three medical dispensaries to survive. • • ENERGY LIFE CYCLE COST ANALYSIS for Spokane Valley City Hall 11707 E Sprague Ave #106 Spokane Valley, WA 99201 Sti r�its.'"\arsaitati, pane .000 Mil ley Prepared By: Ken Hoener Building Energy Simulation Analyst, EIT MSI ENGINEERS Av,_, 1v1EULINK STAUFFENBERG,INC. 108 N.

ENERGY LIFE CYCLE COST ANALYSIS SPOKANE VALLEY CITY HALL SPOKANE VALLEY, WA SECTION 4 EXECUTIVE SUMMARY ENERGY LIFE CYCLE COST ANALYSIS SPOKANE VALLEY CITY HALL SPOKANE VALLEY, WA EXECUTIVE SUMMARY Purpose Pursuant to the requirements of the State of Washington RCW 39.35 and the Office of the Superintendent of Public Instruction (OSPI), the design of new and majorly renovated K-12 schools larger than 25,000 square feet, must include an Energy Life- Cycle Cost Analysis (ELCCA) to account for all energy consuming systems (HVAC, lights, water and envelope) and to include their related costs, as well as first costs (construction costs) and ongoing maintenance/repair costs, in the decision process for selecting the most cost-effective, efficient public facilities. The purpose of this ELCCA report is to compare total life cycle costs of several alternative HVAC (air handling, heating and cooling) systems for: Spokane Valley City Hall for City of Spokane Valley Spokane Valley, Washington As a result of this analysis, this report recommends the optimum system selection based on design with the lowest total life cycle costs. This report also evaluates the compliance of the building design with the provisions of the Washington State Energy Code, 2012 Edition. Project Summary The proposed new building is being designed as a replacement to the current city hall. The typical exterior wall is a basic masonry cavity wall construction. Framing is with metal studs which run continuously past the floor structure for continuity of insulation. The exterior skin is a mixture of brick and concrete block. Pre-Cast Concrete is used as window sills and headers. Relief is provided at the third floor sill level by a step-back in the face of the masonry. There will be two roof assemblies used for the project. The first will be a metal deck roof will have at minimum a layer of R-30 continuous insulation and single-ply roofing. The second will be composition roofing with a continuous layer of insulation and batt insulation between trusses. All roof assemblies will comply with guidelines set forth in the WSEC. Based on the results of the ELCCA which compares first costs, annual energy costs, and ongoing maintenance/repair costs for the four alternative systems over a 30 year economic life cycle, it is recommended that Alternative 3 —Variable Refrigerant Flow be selected for incorporation into the design of the new Spokane Valley City Hall. The key elements that make this the recommended system as well as the most cost-effective choice include: • Lowest overall 30-year life cycle cost. v • Efficient system operation with low annual energy costs due to: o Heat Recovery Ventilation System o High Efficiency Variable Flow Demand o CO2 Demand Control Ventilation o Economizer Capability Variable Refrigerant Flow Systems (VRF) use refrigerant as the cooling and heating medium, and allow one outdoor condensing unit to be connected to multiple indoor fan- coil units (FCUs), each individually controllable by its user, while modulating the amount of refrigerant being sent to each evaporator. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at partial-load conditions. VRF systems allow individual indoor units to heat or cool as required, while the outdoor condensing unit compressor load benefits from the internal heat recovery (some units are in cooling and some are in heating mode). The technology allows for compact, quiet units, flexibility of placement and gives architects and owners more design freedom. Gas-fired, storage tank type water heaters will be utilized. General office use will be provided by water heaters which deliver 140°F water to multiple storage tanks and a master thermostatic mixing valve set to deliver hot water at 120°F. The domestic hot water systems will have pumped re-circulation to maintain water temperature at the remote fixtures.

The elevation is roughly 2,000 ft. above sea level, in a primarily heating climate with 6,842 heating degree days (HDD) and 298 cooling degree days (CDD). The building massing is roughly rectangle in nature, and is three stories in height. The current vision is to create a classic yet contemporary masonry structure, providing a highly visible and distinctive structure at the heart of Spokane Valley. Typical occupancy hours range from 7am to 5pm, with some extended hours for extracurricular and administrative activities throughout the year. The school is open during the summer. Schedules will be used that reflect typical usage within the model. Electricity and natural gas is available onsite, and is supplied by the Avista Utilities. Internal Planning The new building will be comprised of three stories of various office spaces, council chambers, open office areas and conference rooms. The main floor has two front entrances on the east and west side of the building that lead into a main corridor area which connects various office and council chambers area to the north side with the main office areas on the south side to the of the building. Stair cases in the center, north and southeast of the design allow access to the basement, second and third floor. The second and third floors house multiple open and closed office spaces along with multipurpose areas and conference rooms. Large windowed areas provide daylighting to nearly all working spaces. The basement will house mainly storage, electrical and mechanical spaces. Exterior Design The exterior of the building will be constructed of CMU and masonry veneer, with its defining feature being a large, three story curtain wall in the center of the east side providing the main entrance to the building. This also provides the offset in architecture that divides the north and south areas of the building, breaking up the blocky rectangular feel of many buildings in the area. Site Design The Spokane Valley City Hall replacement will be located in the center of the lot on the northwest corner of Dartmouth and Sprague. Public parking will be located to the east, employee parking/loading area to the south, and rapid permit parking to the west. Design Goals The design for the new school is based upon the needs as well as the constraints of the design team, taking into consideration not only desired use of the space, but things such building durability, timelessness, sustainability, and comfort. The design team identified building goals that were important to the users of the new building and were integrated into the WSSP Scorecard and overall building design. The Spokane Valley City Hall project plans to integrate the following: • Energy Savings of 15% or better over WSEC 2012. • Preservation of green space • Minimal footprint • Light pollution reduction • Reduced irrigation water use • Potable water use reduction • Daylight strategies • Low VOC Emitting interior and material finishes • Advanced mechanical filtration • Indoor air quality, adequate volume of fresh, comfortable tempered air • Energy efficiency in lighting systems • High performance HVAC that is energy efficient and controllable • Exterior lighting for security and safety SECTION 6 SIMULATION & ECONOMIC ASSUMPTIONS ENERGY LIFE CYCLE COST ANALYSIS SPOKANE VALLEY CITY HALL SPOKANE VALLEY, WA Energy Simulation Assumptions This ELCCA report is based upon a comparative energy simulation computer model that has been developed for Spokane Valley City Hall, based upon the current architectural, mechanical, and electrical drawings of the aforementioned project. Care was taken to ensure that energy simulation inputs properly reflect the architectural, mechanical, and electrical characteristics prescribed during the design process, and that additional building loads and schedules best reflect the predicted actual building usage. The baseline and alternative model has been developed following the requirements and procedures as outlined in the 2012 Washington State Energy Code and the ELCCA Guidelines for Public Agencies in Washington State. Other standards that may have been referenced during the creation of the energy model simulation include: - ASHRAE Handbook - Fundamentals. - 2012 International Mechanical Code - RS Means Cost Data - ASHRAE 90.1 - ASHRAE 62.1 Modeling of anticipated energy consumption for alternative combinations of systems has been performed using Trace energy simulation software developed by Trane. This program meets the simulation program requirements as outlined in the 2012 Washington State Energy Code. The program uses an hourly calculation method and incorporates meteorological data for the area that most closely matches the real location of the building site. When a weather station does not exist near the building site's location, the energy modeler will use a weather station that best represents the site's location and weather patterns. An overview of modeling assumptions for each of the alternatives can be viewed on the following modeling system matrix spreadsheet and input files. eplacement atrix MSI# 15.11 ALTERNATIVE—1 ALTERNATIVE—2 ALTERNATIVE—3 BASELINE PACKAGED WATER SOURCE HEAT VARIABLE REFRIGERANT ROOFTOP VARIABLE AIR PUMP FLOW VOLUME (DOAS AHU) (AHU) (AHU) - Packaged Roof-Top DX - Heat Pump Units - Variable Refrigerant Flow Cooling Air Handler - DOAS Air Handling Unit Fan Coil Units - VAV Boxes with Hot Water - Cooling Tower - DOAS Air Handling Unit Reheat - Gas-Fired Hot Water Boiler with Heat Recovery for - DX Air-Cooled Condensing ventilation.

By the defaults provided by the General Administration, discount and escalation rates are as followed: Years Rate Real Discount Rate 0-30 2% 0-10 1% Electricity 11-20 2% 21-30 2% 0-10 1% Natural Gas 11-20 1% 21-30 1% Maintenance 0-30 2% Inflation (Nominal) 0-30 3% The ELCCA analysis reviews a 30 year economic building life. Equipment life is based upon either Table 5.4 of the 2005 Washington State ELCCA Guidelines or RS Means Cost Data. Natural Gas, electricity, and other used fuel costs are provided by the local utility company and based upon the schedules applicable to the building type. The following page(s) list the energy rates applicable to this project. The final HVAC system selection will be based upon the results of this ELCCA, as well as other non-monetary factors (i.e. adaptability to building geometry and space constraints, indoor air quality, ease of maintenance, system familiarity/reliability, etc.). SECTION 7 BUILDING ENVELOPE ENERGY LIFE CYCLE COST ANALYSIS SPOKANE VALLEY CITY HALL SPOKANE VALLEY, WA NEW BUILDING ENVELOPE PRESCRIPTIVES Walls The envelope exterior walls are a basic CMU and masonry veneer with a layer of continuous insulation, metal studs and batt insulation. All walls will comply with the requirements set forth in the WA State Energy Code, Table 13-2, for Climate Zone 2.

Flat roofs will be an assembly consisting of a metal deck, a minimum of rigid R-30 insulation and single-ply roofing. Sloped roofing will consist of composition roofing over wood deck, a continuous layer of poly-iso continuous insulation and batt insulation between trusses. Glazing Glazing will be dual-pane insulated glazing units (IGUs) in thermally broken, anodized aluminum frames. Typically, one lite of the IGUs will have a low-E coating. The glazing elements proposed will comply with the requirements set forth in the WA State Energy Code, Table 13-2, for Climate Zone 2. Doors Solid doors will be insulated metal type and will comply with the requirements set forth in the WA State Energy Code, Table 13-2, for Climate Zone 2. Glass doors will be equivalent to the glazing system noted above. Floors Slab-on-grade floors will be insulated at the perimeter with 2" thick rigid insulation extending 24 inches deep or to the top of any existing footings. SECTION 8 HVAC SYSTEMS ENERGY LIFE CYCLE COST ANALYSIS SPOKANE VALLEY CITY HALL SPOKANE VALLEY, WA Alternative 1 (Prescriptive Baseline System)—(Packaged Roof-Top VAV) All occupied zones of the building would be served by variable air volume air handling units (either roof mounted or inside of equipment rooms) with DX cooling, hot water heat and air economizers. The VAV air handlers would distribute air to VAV terminal units located at the zone level and equipped with hot water reheat coils. The VAV air handling units provides the majority of the heating required for the facility, and all of the cooling. The remainder of the heating is provided by the downstream VAV terminal units. The VAV air handling uses a variable frequency drive to regulate airflow to the terminal units. As the call for cooling within the zones is reduced, the fan speed is also reduced to deliver less primary air. The VAV terminal units would be series fan powered units which are commonly used in VAV zones that not only require heat during occupied hours, but also constant volume air delivery. With this system the terminal unit fan is in series with the central fan. Therefore, primary air from the central fan always passes through the terminal unit fan. The terminal unit fan is generally sized for 100 percent zone air flow since all primary airflow passes through it. This terminal unit fan operates whenever the zone is in occupied mode. This ensures a constant flow of air, but the temperature of the air varies. As the zone cooling requirement decreases, the primary air damper in the terminal unit closes. As the damper closes, the air mixture supplied to the zone contains less cool air and more warm recirculated plenum air. The terminal units located along the perimeter use electric reheat coils to compensate for the skin heat loss of the building. Multiple heating water boilers would be used to generate hot water for heating the building. The boilers would be staged in sequence to meet the heating load of the building as the outside temperature drops. The hot water would be distributed throughout the building by variable-flow piping systems. Most air handling units and terminal units will be provided with two-way control valves to provide variable flow operation of the hydronic distribution system, thereby maximizing energy efficiency. Advantages: • Relatively low first cost. • Easy to provide smaller zones. • It's very flexible. The system can be subdivided or expanded into new zones to bit building remodeling or additions easily and inexpensively. • The type of system can easily be designed to facilitate partial occupancy of the building while the remaining portions are unoccupied. Disadvantages: • If the VAV air handling unit fails, all of the spaces served by this unit will be shut down. • Hot water reheat lowers energy efficiency. • Pumps and boilers will require periodic maintenance. • Water loop needs to be chemically treated periodically to prevent corrosion and failure of the components it is circulated through. //2 MSi ENGINEERS Spotione Valley City h.- MEULINK STAUFFENBERG, INC .

By reversing this cycle, the unit has the ability to provide either heating or cooling. Water source heat pumps have compressors in each unit that can be used to produce either hot or cold air as the space conditions dictate, while being connected to a pair of water pipes (hence water source) to provide for heat rejection or heat extraction. During cooling, the heat pump transfers heat from the space to the water loop. As the water loop circulates through the building, other heat pumps that may be calling for heating can transfer this heat back into other portions of the building where it can be used, thus increasing the efficiency of the system. If a majority of the heat pumps are in cooling mode, the additional loop heat is rejected to the atmosphere through a cooling tower. During heating mode, the reverse sequence occurs. If a majority of the heat pumps are in the heating mode, additional heat is provided to the water loop by a boiler. Other options to reject and absorb heat into the water loop include geo-thermal and bi- thermal. Advantages: • Extremely efficient. • If a heat pump unit fails, the entire system doesn't shut down. • This type of system can easily be designed to facilitate partial occupancy of the building while the remaining portions are unoccupied. • This system provides excellent indoor air quality and energy efficiency. Disadvantages: • The most expensive of all of the systems. • The discharge temperature to the space cannot be modulated to suit the space load. Similar to a house furnace, the units are either on or off with respect to heating and cooling. • In-room or in-space maintenance including frequent filter replacement. • Pumps will require periodic maintenance. • Water loop needs to be chemically treated periodically to prevent corrosion and failure of the components it is circulated through. • Each unit contains a compressor; therefore care needs to be taken with respect to the design and placement to reduce the radiated sound levels. • Each heat pump unit contains a compressor that typically needs replaced every ten years. If not accounted for this can be a financial burden on the city. ��®MSI ENGINEERS Spokane tcallev City hall New Construction MEULINK STAUFFENBERG, INC.

By operating at varying speeds, VRF units work only at the needed rate allowing for substantial energy savings at partial-load conditions. VRF systems allow individual indoor units to heat or cool as required, while the outdoor condensing unit compressor load benefits from the internal heat recovery (some units are in cooling and some are in heating mode). The technology allows for compact, quiet units, flexibility of placement and gives architects and owners more design freedom. Advantages: • Very efficient system. • Zones or rooms can be designed to exact needs, taking into account occupancy, solar gain parameters, and diversity of usage. • VRF systems utilize small diameter pipes (refrigerant) and ducts (ventilation air only) which makes ceiling space coordination easier. • Easy to provide smaller zones. • This system is ideal for an application where quiet is a necessity; meeting rooms, private offices and conference rooms. • The indoor units come in a variety of styles and give the owner flexibility in deciding on the style, from wall mounted, ceiling mounted, or concealed in the ceiling space. Disadvantages: • System maintenance requires an experienced refrigerant technician. • Relatively new technology in the U.S. "� MSI ENGINEERS spol►arie valley City ball ����v New Construction /D"�.'\� MEULINK STAUFFENBERG,INC.

General school use and kitchen hot water will be provided by water heaters which deliver 140°F water to multiple storage tanks and a master thermostatic mixing valve set to deliver hot water at 120°F. The domestic hot water systems will have pumped re- circulation to maintain water temperature at the remote fixtures. If necessary due to water quality issues, water softeners will be provided in order to precondition water for the hot water system, which will help prolong the life of the heaters and help avoid mineral buildup on shower heads and faucets. Low flow faucets and flush valves will be used throughout the facility. Toilet rooms will have wall hung water closets (1.1 gallons per flush) and urinals (1/8 gallon per flush) with hard-wired, sensor-operated flush valves. Wall hung lavatories will be low flow (.5 gpm), hard-wired, sensor-operated faucets. Showers will be low flow (2.0 gpm) with manually operated pressure-balanced mixing valves.
