Building 669 Integrated System Project Design
• Integrated Technology Optimization
– Envelope
• Roof Scenarios
–Black EPDM membrane as roof surface finish with R-24
–PVC membrane (reflective roof) with R-24
• Walls
–Polyurethane rigid foam board application on the interior (R-24)
–Hybrid Insulation application- 2” SPF + 3” Blown-in Cellulose fill (~R-25)
• Glazing Scenarios
–Existing single pane clear glazing
–Double glazed solarban 60 + etch glass combination window for better thermal performance and high Tvis
HVAC System Retrofit Options Assessed
• Integrated Technology Optimization
– Baseline (Window mount air conditioners/infiltration, boiler heat)
– Rooftop A/C system (heat pump)
– Dual compressor rooftop A/C (heat pump)
– Variable speed rooftop A/C (heat pump)
– Multi-split heat pump
– Geothermal (or river source/sink) heat pump
– VAV DX system through the whole building
– DOAS system through the whole building
– Radiant heating/chilled beam cooling
– Energy recovery ventilator
– Demand-controlled ventilation
