Sustainable Site Design
– Stormwater Management:
– Restore Habitat
– Geese Deterrent Design
– Bike storage, showers and changing rooms
– Minimize heat island
– Light Pollution Reduction:
Site: Design Goals
Berm & Reforested Buffer Zone
Berm: • Energy Efficiency – thermal mass cools data center • Executive terrace overlooks wildflower meadow • Site Context – residential/mixed use • Ameliorates bedrock conditions
Stormwater: • Reforestation • Wildflower
meadow • 2162 gsf roof
terrace garden • Detention basin &
rain garden • Native species- no
irrigation
Wet Meadow & Cistern for Roof Terrace
• 169 surface parking spaces, 48 in reserve, drains to wet meadow"
• Planted to discourage geese"• 23,500 gallon cistern to be fed from
2nd floor flat roof and east pitched roofs
• 2,162 gsf Roof Terrace irrigated from cistern, 4-6,000 gallons monthly
Light Pollution Reduction
• Bi-level lighting- non-security lights on time clock inside and out,
• Dim exterior pole fixtures • Full cut-off energy efficient
fixtures
Water Efficiency
• Drought Tolerant and Native Species 3.5 million gallons saved, mulching reduced
• Efficient Fixtures and Fittings 48% reduction interior water usage: waterless urinals, dual-flush toilets, low-flow showers , automatic faucets
Energy and Atmosphere • 31% less energy usage • Mechanical & Electrical:
– Intelligent Measure of Demand: Occupancy & Photo voltaic Sensors, BAS, watt stopper, polling of zones of 5 offices, hot isle & cold isle for data center
– High Efficiency, bi-level site lighting tied in with BAS – Leveraging Ambient Temperature & Lighting: Daylight harvesting, free
cooling, energy recovery wheels for conference center – Quality Equipment: Variable speed pumps & fans, EER of 10.4
• Architectural – Superior Insulation: Berm, Green Roof, Roof, bio-based spray insulation – High Performance Glazing; 23% of façade, 90% of views – Daylight Design: Orientation, Overhung windows, Interior Glazing,
Courtyard – Task Lighting, mirrors, T5 lamping, efficient fixtures
Data Center Heat Sink Overhung, South-facing Fenestration
Roof Terrace
• 20% Recycled Content: – steel, slag concrete,
roofing, aluminum
• 20% Regionally Extracted : – concrete, gypsum
board, landscaping, berm
• Rapidly Renewable – bamboo , insulation
• FSC Wood
Materials & Resources
• Cradle to Cradle – Entire Life Cycle
• Embedded Energy
What LEED Does for Design: Green = Better + More Teamwork & Communication
• Better Building: Smarter, Higher Quality
• Better Teamwork: Integration, Prioritization
• Better Communication: Design Charettes, More Documentation
• Better Skills: Requires Sustainability Competence
What LEED Does for You: • Decreased
Annual Costs: • Energy – 31% • Water – 48% • No irrigation,
Maintenance • Accountability:
• USGBC 3rd Party Accreditation
• Quality of Life: • Improve Employee Communication and Efficiency • Increase connection with environment – views, bikes and trails on
buffer zone, roof garden, executive terrace • Water Cycle Management - “closing the loop” • Greenhouse Gas Emissions Reduction – energy, refrigerant • Smaller Environmental Footprint – regional, recycled, and rapidly
renewable materials • Higher Quality – IAQ, Building Materials
