    I will need to edit curtain walls, mullions, and windows later.

    windows:

    The windows are evenly distributed on the exterior walls. I will need to make them aligned to the tilted walls later.

    exterior doors:

    The two exterior glass doors are located on the curtain walls of the lobby. I will need to adjust them to align them with the tilted wall later.

  • Use your Building Element Model to create an Energy Model.

Analytical spaces

Analytical surfaces

image
  • 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.

The energy model missed some parts of the roof. I will need to figure out what has happened later.

  • Be sure to set the Operating Schedule factor tile to use the BIM value.
image
  • Narrow the range of values being considered for the building envelope-related factor tiles to focus on the BIM Model value or better.

(For WWR, I chose 30% instead BIM Model or better values, because the lower the WWR, the better the EUI result, but no WWR is not quite possible.)

  • 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.
    • While a lot of factors do not make significant changes, some of them do:

    • Operating Schedule: 12/5 (BIM for this one)
    • Lighting Efficiency: 0.3 W/sf
    • Plug Load Efficiency: 0.6 W/sf
    • HVAC Type: ASHRAE Package Terminal Heat Pump
    • PV - Panel Efficiency: 20.4%
    • PV - Payback Limit: 20 yr or 30 yr
    • PV - Surface Coverage: 90%
