Test Scenario 1: Analyze the Initial Building Model
- Operating Schedule to 12/5
- Roof Construction to R38
Test Scenario 2 : Use Insight to Explore the Impact of Building Envelope-Related Design Decisions
By adjusting these factors, I go the EUI to 52.1 kBtu/ft2/yr. Factors that I have considered:
- Thermal Properties of Wall Surface (Wall Construction) for all orientations: R13 wood
- Glazing % (Window-to-Wall Ratio) for each orientation (North, South, East, West) . E-W: 15 %, N-S: 65 %
- Thermal Properties of Glazing Surfaces for each orientation: Triple LowE glass for NSEW facade
- Window Shading amount for each orientation: 2/3 WinHeight for NSWE
Test Scenario 3: Use Insight to Explore the Potential Impact of Power and Lighting Measures (versus Building Envelope Measures)
Use the Insight Factor, I continue adjust these factors:
- Plug Load Efficiency: 0.6W /sf
- Lighting Efficiency: 0.3 W/ sf
- Daylighting & Occupancy Controls : add DL, OC
The EUI go down to 32.3 kBtu/ft2/yr by adding these power and lighting measures which is for me very impressive
Test Scenario 4: Use Insight to Explore the Benefits of Adding Photovoltaic Panels to Your Design
Use the Insight Factor tiles to explore the impact of Photovoltaic Panels, as below
- Surface Coverage: 90%
- Panel Efficiency: 20%
- Payback Limit: 30 years
The result reduces impressively to minus 9.38, which means the energy and PV panel can make the building Netzero, and furthermore, can produce a surplus of energy back
To achieve the best result, it is clear that we have to use and mix multiple passive and active design strategies. The building can meet Netzero and produce a surplus amount of energy, however, we all assume that it meets all of the perfect factors and for me, in the reality, it is difficult to achieve this target
