Shading protection on summer solstice.

The Wall Properties I have chosen are as follows. In order to optimize heat retention for passive solar gains in the building, it is recommended to have wall R-Values that range from R40 to R60. At an R-Value of almost 54, I have chosen to use CMU on Mt. Stud walls.

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

  • 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.

  • 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.
