Project A Initial Building Shape Study

We have used eQUEST to make initial inquiries (Shape Study 2) into appropriate energy-efficient building configurations. Starting with an absolutely "dumb" square box basic information has been used to define the initial base case:
1. 5000 sqft office/warehouse building
- Office-1800 sqft (40%)
- Warehouse-3000 sqft (56%)
- Restrooms-200 sqft (4%)
2. Phoenix, AZ TYM2 weather data location
3. HVAC-DX coils with natural gas furnace
4. No daylighting
5. Square footprint (70.7ft x 70.7ft)
6. Perimeter zone depth - 15ft
7. Floor to floor height - 17ft
8. Metal frame construction (R19 insulation)
9. One door on each facade
10. Double pane clear glazing with aluminum frames (without thermal breaks)
11. Window to wall ratios
- North/South - 32.6%
- East/West - 10%
12. No exterior window shades
13. Building operates 7 days/week from 7am to 4pm

Based on the above described base case a number of different building configurations have been parametrically modeled in eQUEST using the EEM wizard. The results of this shape study have been summarized according to predicted site and source energy use.
