1)
- the wall and roof surfaces:
- Exterior Walls: Brick or Brick and CMU on metal studs
- Exterior Finish: Brick and/or CMU
- Membrane Layer: Air Infiltration Bar
- Plywood
- Metal studs
- Membrane Layer: Vapor Retarder
- Interior Finish: Gypsum Wall Board
- Roof: Accessible part (lower level):
- Struct - 3” Concrete on 2” Metal Deck (Accessible Roof = higher Live Load)
- Half of it was left as it is for mounting solar panels (will apply insulation and finishing)
- The other half is a green roof containing earth and grass (higher load again thus should be designed more as a floor rather than a typical roof)
- Roof: (higher level):
- Struct - Metal deck with insulation and EPDM Membrane
- Will be used for mounting small scale wind turbines
- the openings/glazed surfaces
- Honeycomb curtainwalls on the front side of the building
- Typ. 1” glazed panels
- Typical Storefront curtainwalls on the first floor, on the right side and back
- Typ. 1” glazed panels
- Main Entrance shown below, Emergency exit on the left side of the building
- Roof exit
- One skylight made of honeycomb glass panels (on top of the atrium)
- Use your Building Element Model to create an Energy Model.
With all BIM values and optimized with PV:
- 60% coverage
- 20 year pay back
- 18.6% efficiency
Other Key Factors:
- Building Orientation
- WWR
- Window Glass Type
- Wall - R13+R10 Metal
- Roof Construction
- Infiltration
- Lighting Efficiency - 0.3 W/sf
- Daylight & Occupancy Controls
- Plug Load Efficiency - 0.6 W/sf
- HVAC - High Eff. Heat Pump
- Use one of the Daylight Analysis methods demonstrated to assess the daylighting levels available with your proposed building envelope design:
- Paste an image of the resulting Illuminance Map.
- First Floor:
