Building Envelope

  • Wall surfaces

The goal for the exterior walls was to have enough insulation as well as a wood finish for biophilic design.

image

I kept my interior walls as standard 5-inch partition walls with 2-hr fire resistance for now. The goal is to change the finishes to the wood without reducing the fire performance of the walls.

  • Roof surface

I added an extra layer of insulation to the roof and kept the asphalt shingle as finishing.

  • The openings/glazed surfaces

I changed the properties of light transmittance and solar heat gain coefficient for the glass panels used for the curtain walls. I also made the mullions wooden and changed their sizes for shading.

image

I also kept the same light transmittance and solar heat coefficient parameters for curtain wall doors and sliding windows.

image

For smaller windows, I picked double-glazing glass and changed window frames to wood.

image
  • Shading/sun control

I made horizontal shading mullions for curtain walls on the south and north sides as well as vertical shading mullions for the west side.

image

I also provided roof overhangs and shading over all the smaller windows.
