9. Passive Design clerestory windows and shading devices

12. Optimize Design reduce loads insulate well daylight reduce infiltration address thermal breaks passive cooling

13. WALL Exterior Wall 4 inch insulated wall panel over Snap-R 1 inch EPS spacer over 10 inch girt (11in batt insulation) = R-55.7

14. ROOF Roof 6 inch insulated roof panel over 12 inch metal girt with batt insulation = R-70

15. specified double wall insulated dampers on all envelope penetrations provided thermal and load bearing insulation pads at structural steel connections Thermal Bridging

17. Challenges: maintain building interior temperature between 50 and 80 degrees F WITHOUT the use of any active mechanical systems net zero site energy Software Selection: IES vs Epro Thermal / Energy Modeling

18. Where to Look? Net Zero Energy Building Tip: Understand building physics Infiltration Opaque Envelope Windows

19. Infiltration construct an airtight building followed ASTM E1827-11 single point method for air tightness looking for rate less than 0.1 cfm/sf door blower test, identify leaks with smoke guns actual leakage 0.08 cfm/sf

20. once load reduced, use night flush through one fan with thermal storage in internal concrete walls and slab Net Zero Energy Building Tip: Understand micro climate Mechanical Solution

21. Temperature Results

23. Energy Results

24. If 6 months results are extrapolated to one year, Total Building Energy consumption = 3,588 kWh That is 1.44 kBtu/sq.ft-year Modeled was 1.66kBtu/sq.ft-year Energy Results Net Zero Energy Building Tip: Model accurately
