Your Name
Your building envelope recommendations for this practice exercise should feature:
- Your recommended settings for the Insight Factor tiles
- A screenshot from Insight showing the Predicted Mean EUI and the range of values resulting from your assumptions
- Your best result Predicted Mean EUI achievable for each of the three test cases outlined above:
- achievable through building envelope choices
- Wall Construction: 12.25 Inch SIP or R38 wood
- WWR - Southern Walls: Range from 50%-95%
- WWR - Northern Walls: Range from 2%-65%
- WWR - Western Walls: Range from 15%-50%
- WWR - Eastern Walls: Range from 15%-80%
- Window Shades (All): Range from 1/6 Win Height - 2/3 Win Height
- Window Glass South: Dbl LoE or Trp LoE
- Window Glass North: Range from Sgl Clr - Trp LoE
- Window Glass West: Dbl LoE or Trp LoE
- Window Glass East: Dbl LoE or Trp LoE
- achievable through building envelope + power & lighting choices
- Plug Load Efficiency: 0.6 W/sf
- Drops by 3.9
- Daylighting and Occupancy Controls: Occupancy controls or Daylighting and Occupancy Controls
- Drops by .5
- Lighting Efficiency: 0.3 W/sf
- Drops by 3.6
- achievable through adding Photovoltaic panels to the mix.
Recommendations to achieve this result:
Biggest impacts: Wall construction choice (drops by 3.4), and window glass choice (except for North side), shading did not have large impact.
Adding Power & Lighting drops the EUI by 8.2
Recommendations to achieve this result:
Plug load and lighting efficiencies have much bigger impact than daylighting and occupancy controls
Adding Power & Lighting drops the EUI by 38.82! WOW!
Recommendations to achieve this result:
- PV - Surface Coverage: 90%
- Drops by 6.52
- PV - Payback Limit: 20 yr - 30 yr
- Drops by 5.82
- PV - Panel Efficiency: 20.4%
- Drops by 1.77
