Transcript of LEED for Commercial Buildings

LEED Certification
Commercial Buildings Sustainable Site Water Efficiency Energy
Atmosphere Materials
Resources Innovation
Design Process Indoor
Environmental Quality Building on previously undeveloped land- discouraged
Impact on eco-systems and waterways
Regionally appropriate landscaping
Smart transportation
Storm-water run-off control
Erosion reduction
Light pollution
Heat island effect
Construction related pollution Smarter use of water- indoors & out
Inside- Efficient appliances, fixtures and fittings
Outside- Water-wide landscaping Sustainable Site Energy & Atmosphere Commissioning
Design & Construction
Systems & Lighting
Renewable and clean energy sources
Energy generation
On site
Off site Materials & Resources In both construction and operation of building

Selection of materials- sustainable growth, harvest, production & transport
Waste reduction
Reuse and recycling Indoor Environmental Quality Indoor air- VOC's, offgassing
Natural daylight & views
Acoustics Innovation & Design Bonus Points for new & innovative technologies
Areas not included in any other section
Credit for having LEED AP (Accredited Professional) on team Water Efficiency Wind pressures & cooling coils
100% outside air lower levels
Air passing over cooling coils- to decrease temperatures falls downward
Heating coils in lower levels drive air up- for heating as needed Solar Thermal Panels Vaccuum tube collectors
Supplemental central campus hydrolic system--> delivers cooling & heating Clerestory & Skylight Day-lighting
Chimney effect--> for buoyancy air system exhaust Photovoltaic Panels Over 6000 sq feet (how many football fields?)
Reduces annual costs by $20,000! Fenestration & Daylighting high performance glazing
maximizes interior light & views
minimizes heat loss and gain Access Floor Plenums Efficient distribution of air Green Materials Air Quality
Low emission (low VOC) interior finishes
Local Materials
Redwood benches--> from overcrowded groves on campus
Recycled & Regional Materials
Carpet tile, floor tile, batt insulation, acoustical panels, countertops
Materials certified by third parties- Forest Stewardship Council, Greenguard for Children & Schools etc. Radiant Atrium Slab Heating & cooling of two story communal space
Helps drive buoyancy system Passive Shading Louvers & canopies of south facing glazing
Additional protection against heat gain Biofilter Runners Rainwater collected on roof-->
Funneled through landscape
"Runnels"- Naturally filter storm runoff for water quality- before it enters local waterways
Drought-resistant vegetation LEED Certified Buildings Near You! LEED EB (Existing Building) Platinum Rating David Brower Center, Berkeley, CA Realigned loop road, building turned 90 degrees to an east-west axis.
Optimum solar orientation
Maximizes day lighting
Harvesting solar energy.
Larger building site = new campus quad
Additional outdoor teaching/learning spaces
Landscaped gathering place for social interaction.
Built on previously developed land Site Selection Reduced Light Pollution Minimizes lighting pollution of surrounding areas Plumbing Low-flow plumbing fixtures
Reduce indoor water use by 48%!
= 117,000 gallons of potable water savings annually! BMS (Building Monitoring System) Monitors and controls major mechanical and electrical systems & equipment
Weather Stations on roof transmit data to BMS
Optimal function of buoyancy driven ventilation
CO2 Sensors and thermostats in classroom
Monitored by BMI--> ventilation adjusted
Customizable controls also available
Lighting levels monitored and controlled Atrium Exhausts warm air through clerestory windows Buoyancy System: (Intake Tower & 100% Air System) Hines Building, 101 California St, SF Transamerica Building, SF Intercontinental Hotel, SF LEED NC (New Construction) Platinum Rating LEED EB (Existing Building) Gold Rating LEED NC (New Construction) Gold Rating CASE STUDY- LEED PLATINUM Deanza College, Cupertino, CA LEED Resources LEED Building Certification Requirements
