The baseline case with an operating schedule on 12/5 and roof construction of R-38 results in a predicted mean EUI of around 60.1 kBtu/ft2/yr.
Impact of Building Envelope-Related Design Decisions
The following changes were made to the building envelope-related designs, and a predicted mean site EUI of 51.6 kBtu/ft2/yr was achieved.
Impact of Power and Lighting Measures
Adjusting the power and lighting measures resulted in a significant decrease of the predicted mean EUI with the value dropping to 17.2 kBtu/ft2/yr.
Impact of Adding Photovoltaic Panels
Lastly, adding photovoltaic panels decreased the EUI value to 6.99 kBtu/ft2/yr.
Overall, adjusting the power and lighting systems made the largest impact on the predicted mean EUI. Also, adding the solar panels helped the building achieve the Architecture 2030 goal.
