12 ENERGY USE REALITY REMEMBER, BUILDINGS DON T USE ENERGY, PEOPLE DO.

22 ENERGY GOAL Existing EGWW building (437,777 sf) /- 15% Renovated EGWW target range

23 ANALYSIS BUIDLING ORIENTATION o 20 Transform a 512,400 square foot, 18-story, 1974 office building into a LEED Platinum cornerstone of GSA s green building portfolio. BUDGET: $ 141,000,000

24 ENVELOPE STUDY SURROUNDING BUILDINGS June pm am am pm

29 DATA DRIVEN DESIGN FROM STUDY TO DESIGN TO CONSTRUCTION REEDS ON EAST FAÇADE

30 DESIGN/ANALYSIS EAST & SOUTH ELEVATION STRATEGIES Summer mid-day sun (high angle) Low Glazing to Wall Ratio 40% glazing Low Infiltration Rate 0.06 CFM Well-Insulated Wall Equinox morning sun (lower angle) Daylighting Light shelves bounce light 16ft. into interior

31 DESIGN/ANALYSIS WEST ELEVATION SHADING STRATEGY Shading reduces the heat gain on the building minimizing the energy needed for cooling. West Facade Reeds provide avg. 50% shading South & East Facades Combination vertical + horizontal shades North Facade No shading

32 PORTLAND DOWNTOWN AREA NETWORK Reverse power flow not permitted in downtown network. 100 kw buffer required by utility. Lost PV production between 15-20%

33 EGWW NET ELECTRICITY

34 EGWW OPPORTUNITY LOST More than 35% of possible production is lost
