A SUMMARY OF SUSTAINABLE DESIGN FEATURES

• Use of natural terrain
• Preserve ravine and trees to the south and west
• Preserve views and sun exposure

• L-shaped floor plate reduces depth and permits daylighting and facilitates natural ventilation
• Building Orientation maximizes southern exposure for passive solar heating in winter and daylighting
• Building wraps around the existing building and reduces heat loss, and creates an enclosed courtyard accessible from public corridor
• The building includes roof terraces on the south side, a good candidate for roof gardens

• The design employs windows, sun-shades and skylights to maximize daylighting
• Natural ventilation is assisted by a combination of operable windows, clerestory, three thermal chimneys and a network of interconnected large volume spaces such as Galleria and south corridors
• Energy simulation modeling was used to show impact of each strategy in energy saving with an overall saving of 36% achieved over the Model for National Energy Code for Buildings
• HVAC units are equipped with heat recovery modules
• Double glazed Low-e glass with thermally broken window frames are used
• Highly energy efficient light fixture are specified with sensors to automatically turn off the light when not needed

The building has a very low demand for domestic water. Rain water drainage and surface run off are designed to be delivered back into nature.

E. Materials

• Lumber is used in the form of glulam columns and trusses which do not require cutting large trees. 
• Metal clad roof on wood structural framing exposed inside, clerestory windows on both sides provide daylighting.
• Many areas in the building have exposed structure that reduces need for interior finishes.
• Linoleum flooring in some areas. 
• Exterior cladding is a combination of cultured stone, recycled, and metal siding which is reusable and recyclable.
