Energy Model
Before any adjustments
After changes:
Initially, although my building did meet ASHRAE standards, it was far from meeting my goal of becoming close to or surpassing the architecture 2030 threshold. Therefore, I made some adjustments that were plausible for the construction of the building. These adjustments include the type of window glass used in the western and southern walls, the construction material for the roof, the operating schedule and infiltration (to match my BIM model). Some elements I did not want to modify, such as window-to-wall ratio because these were fundamental to my design, and I was able to make the Architecture 2030 threshold without modifying these elements. I also wanted to maximize the use of Photovoltaic Panels in my building, which would be placed on the flat roofs. Additionally, I thought the PV would be really effective since my building is mostly set to run during business hours, which is when PV can be effective at generating electricity. The PV Panels would not only help reduce dependency on non-renewable resources for my building, but it would allow me to save operating costs in the long run as well.
For 2 Units
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
For 3 Units
- 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.
For 4 Units
- 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.
- 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.
