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

According to the building location, two sides of my building are surrounded by the sea and facing the sun, while the other two sides are blocked by other tall buildings, so I choose the wall materials according to different situations. For the south and east sides, because they are directly exposed to sunlight, the indoor temperature is easy to rise, so I choose brick with low thermal insulation coefficient. Meanwhile, since the design of my structure is to gradually reduce layer by layer, it will form a natural shield and bring some shade to the first and second floors, so I choose materials with thermal insulation coefficient of 59 for the two sides of the third floor. For the two sides of the first floor and the second floor, I choose brick with thermal insulation coefficient of 66. For the north and west, because they are blocked by tall buildings and the sunlight is difficult to direct, so in order to maintain the indoor temperature, I choose the wall material with insulation factor 71. My roof design is a green roof, while leaving room for the solar system, I also set up a large skylight for viewing and allowing sunlight to enter the structure from above. The ratio between my wall and the glass wall is about one to one, which can provide good support and viewing functions for the building. Meanwhile, I also set vertical and horizontal mullions for the glass wall to better protect and support. The entrance door to the building is more in line with the museum design with a revolving door. For the shielding system, it is mainly the natural effect brought by the structural design of itself and the use of curtain walls.

  • 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.
      • 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.
