Achieving a LEED Platinum rating from the USGBC the project, through energy modeling and BIM technology, takes advantage of the campus infrastructure and local climate to create a highly environmentally sustainable facility. Some of these passive and active strategies include:
• Adaptive reuse and restoration of the existing residence maintains
the majority of the structural and non-structural elements
• Frameless glass windows and walls, along with extensive skylights
provide daylight to all the occupied spaces in the new structure
• Moveable glass walls along the collaborative lounge with transfer
ducts on the opposite wall and low ventilation fans provide the
optimum natural ventilation
• Operable sliding panels integrated into the north and west walls
of the Meeting Room space provide the natural ventilation for a
heat stack effect that is ventilated through automatic, mechanized
louvers located in the southern skylight well. Sensors on the
sliding panels trigger or disconnect the HVAC system and the heat
exhaust system accordingly
• The concrete slab on grade creates a cooling heat sink to reduce
the cooling loads for the building
• Manual and mechanical lighting and HVAC controls create a flexible,
adaptive environment that optimizes the use of energy
• Solar energy from the nearby campus array is harvested and
allocated
• Native, drought tolerant plant selection and high efficiency drip
irrigation and controls
• Gardens, paths and courtyard incorporate permeable paving (red
gravel, decomposed granite, concrete pavers) in order to recharge
the aquifer, prevent water run-off and reduce the heat island
effect
• A white, energy-star rated roof reflects heat and sunlight reducing
the heat island effect
LEED Energy Calculations:
Code: ASHRAE 90.1-2007
Baseline: 111.8 kBTU/sf-yr (214,270-kWh/yr) energy use,
Modeled: 79.3 kBTU/sf-yr (151,429-kWh/yr) energy use,
29% reduction
The water use reduction is 35% as compared to baseline:
Code: LEED 2009, EPAct 1992
Baseline: 18.18 kGal
Modeled: 11.86 kGal
