3 Getting Everyone on the SAME PAGE Owners Bankers- Architects- Constrction office- Constrction in the field Sppliers -

4 Words to remember I have a box to bild and this mch money to bild it

5 Green Bilding Programs what we hear Landscape design incorporates all native droght resistant plants. Compter controlled irrigation systems Advanced window glazing- to redce solar radiant heat loads and decrease HVAC Load Roof top Photovoltaics or renewable ready bilding Bilding envelope improvements sing rigid and spray foam inslation Variable Refrigerant flow technology HVAC system Dedicated Fresh air system Wireless lighting controls for lighting system Tors and Pblic Training Contractor Training Certified installation training

6 Objectives- Gain a basic nderstanding of mltiple green bilding certifications Energy Focsed ENERGY STAR, DOE Net Zero Ready, Passive Sstainable Focsed ICC 700, LEED Understand the financial reasons and benefits to owners Lower Down Payments, Proper tility allowances Programs that give points State Programs, Federal Programs Comprehend the TEAM Design and Development process Its all abot trade offs Design Bild is the way to go or plan on a lot of sbmittals

7 Objectives- Basic Concepts of relating bilding envelope to sizing then relate to comfort High performance bildings need high performance controls One change may case other changes Recognize how otcomes drive high performance bilding

8 HUD allowances How to se on a 2 Bedroom Electric Heat = $38.00 Cooling = $9.00 Other = $34.00 Water Heating = $27.00 Range = $12.00 Refrigerator = $13.00 TOTAL = $133.00

28 Passive Hose Why? Governor s Office State Hosing Athority Set p a competition 3 grops Prize $500,000 Tax credits

29 Passive Hose Why I like it

30 Passive Hose Fondation Walls inslation - R-88 Slab Inslation R-28

31 Passive Hose Wall Inslation R-40 Redced Thermal Bridging What happened??? New engineer, new wall company, new framing crew Had to add PV at this point to the project What we wold do NEXT time. The wall panel company needs to be part of TEAM Move to a SIP s wall

32 Passive Hose Roof R-87 Roof trss filled with blown in fiberglass More foam 22 inches Changed dring constrction thr drains to slope Air Sealing?

33 Passive Hose Windows One spot the TEAM fell apart. Flashing mid set window? Framers bdget? Air Sealing?

34 Passive Hose Air Sealing and Testing two ways whole bilding nit = 60 CFM blower door

35 ICC Units Townhose Style State money involved Gas Heat and Water Heating Energy Star Path $67.00 per month tilities

36 ICC 700 Landscape design incorporates all native droght resistant plants. Compter controlled irrigation systems Advanced window glazing- to redce solar radiant heat loads and decrease HVAC Load Roof top Photovoltaics or renewable ready bilding Bilding envelope improvements sing rigid and spray foam inslation Dedicated Fresh air system constant rn bath fan Recycle Program dring constrction to divert from landfill Maintenance and tenant edcation
