- 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.
- Engergy Model
The following is the Analytical Surfaces model.
A trail energy model is built, and the result is shown as follow:
Since the top pf two stairways are openwide, so there are some energy dissipation. As an improvement, some walls and roofs are implemented:
The new resulted EUI is a little bit lower, so it’s helpful. To be mentioned that the hemispheric botanic garden is still a big problem to be solved. Further optimization is needed.
The resulted EUI without any change is 91.1 kBtu/ft2/yr, which is lower than the ASHRAE 90.1 (126.4 kBtu/ft2/yr), but still much higher than the ARCH 2030 (19.8 kBtu/ft2/yr)
Then the following factors are modified for optimization:
With these changes made, the resulted EUI could be reduced to 44.4 kBtu/ft2/yr. If we consider the PV system, this result could be further reduced:
With the help these updated changes, the resulted EUI could be further reduced to 19.6 kBtu/ft2/yr, which is less than the ARCHITECTURE 2030 (19.8 kBtu/ft2/yr). The energy conservation of the model is ideal with the adoption of these strategies. （Some factors, such as the PV coverage, need further modification in the future）

- 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.
- Paste an image of the resulting Illuminance Map.
- Option 2: Use the Revit Cloud Render tool to produce Illuminance Renderings of three key areas in your building model.
- Place cameras in your model to create 3D camera views to be rendered.
- Use the View > Cloud Render tool to generate Illuminance Renderings for these camera views.
- Paste images of the Illuminance Renderings into your Design Journal posting.
- Daylight Analysis
I choose to use option2 here, utilizing the Revit Cloud Render tool:
6.1 Gift Store at 1st floor
6.2 The Botanical Garden at 1st floor
6.3 The Stairways at 3rd floor
