Please share your design showing the features of the proposed building envelope, including the locations and characteristics of:

• the wall and roof surfaces
• the openings/glazed surfaces
• windows and/or curtain walls
• doors
• skylights
• any shading or sun control features

Features

• The wall surfaces (exterior) are made of EIFS on metal studs for good insulation and to hold little heat. They have:
• U Value of 0.0152 BTU
• R Value of 65.9
• Thermal Mass of 0.885 BTU/ft^2
• Absorptance of 0.7
• There is one curtain wall containing glass panels with the following properties:
• 1” thickness
• Triple glazing - 1/4 thick e=0.2
• Visual Light Transmittance (adjusted with coloring glass) of 0.64
• Solar Heat Gain Coefficient of 0.56
• Thermal Resistance of 3.70 (h*ft^2*F)/BTU
• R Value of 3.70
• U Value of 0.27
• Vertical spacing of 4”, horizontal spacing of 7”
• Mullions 2.5” x 5” rectangle
• The windows on the non-curtain-wall side of the building have the following properties:
• Triple glazing - 1/4 thick e=0.2
• Visual Light Transmittance (adjusted with coloring glass) of 0.64
• Solar Heat Gain Coefficient of 0.56
• Thermal Resistance of 3.70 (h*ft^2*F)/BTU
• R Value of 3.70
• U Value of 0.27
• Interior Walls

• Roof

• Use your Building Element Model to create an Energy Model.
• Submit this Energy Model to the Insight analysis tool to explore how the choices and specifications you’ve made in your Building Element Model affect the predicted energy performance.
• Be sure to set the Operating Schedule factor tile to use the BIM value.
• Narrow the range of values being considered for the building envelope-related factor tiles to focus on the BIM Model value or better.
• Explore how other factors (such as Photovoltaic panel options) can further improve your building performance — by using renewable energy to complement your energy saving envelope features.
• Share the results of your Insight optimization:
• Include an image of the EUI meter and range indicator after you’ve made your adjustments to show what your current assumptions predict and how much potential there is for additional improvements.
• List the key Factor Tile settings that are driving these results

Potential Changes/ Additions

• I plan to include solar panels, and if I do so at a 20-year payback limit, 75% surface coverage, and 18.6% efficiency I will observe the following improvement:

• One element I did not include was window shades, so I ran an analysis of I were to add them at 1/3 window height on all sides. I observed no change from the above value with this change (EUI = 54.0)
• If I did the above and focused on the electrical elements, specifically 1.3 W/SF plug load efficiency, ASHRAE Heat Pump, and Daylighting and occupancy controls I would see the following improvement:

In general, there is the most room for improvement through energy generation (PV) and electrical elements. Changing other elements yielded little energy differences. I plan to include these high-energy-reducing potential elements in future model iterations.

• Use one of the Daylight Analysis methods demonstrated to assess the daylighting levels available with your proposed building envelope design:
• Choose one of these methods:
• Option 1: Use the Revit Lighting Analysis extension to produce an Illuminance Map of one of the levels of your proposed design.
• Be sure to watch the videos for tips about what you’ll needed to include in your building model for the lighting analysis to produce valid results. For example, you’ll need to place Rooms and Floors.
• To analyze your model for 0 credits, be sure to choose a single level at a time and use 72 inch grid as the analysis resolution.

• Paste an image of the resulting Illuminance Map.
