LEEDThe Leadership in Energy and Environmental Design

U.S Green Building Council 1998

LEED• Sustainable Site 26

Site Selection – Urban Redevelopment – Alternative Transportation –Reduce the Site Disturbance

• Water Management 10Water Efficient Landscaping – Innovative Wastewater Technologies – Water use Reduction

• Energy and Building Skin 35Fundamental building system – Minimum energy performance – HVAC – Renewable energy – Green power

• Materials Use 14Recycled contents – Building Reuse – Waste Management

• Indoor Environment Quality 15Thermal comfort – Low Emitting Materials – Ventilation Effectiveness – Daylight and views

Green Globes Rating Scale

Green Globes Example•Fedral court building•Location : Toronto•Architect : Kuwabara Payne Mckenna Blumberg (KPMB)•Area : 20.907m2•Construction from 2003 to 2006•Rating : 4 Globes

Energy•Best Orientation East-West • integration between natural and artificial light•Using low U-value Glass •Energy metering•Using energy saving systems (lighting – ventilation)•Facilities for bikes riders and near transportation

Green Globes ExampleWater•Using water saving systems in toilets

Material and Recourses•Using local materials (low environmental impact)•Materials that minimize consumption of resource (low maintenance)• building adaptability and disassembly •Facilities for recycling and composting (330 m2 area store)

Emissions•As a result of above this building causes low carbon emissions

Indoor environment quality•Monitoring systems for CO2 in car parking area •Source control for indoor pollutants •Ventilation system renews 100% of the indoor air•80% of the building use natural light•Thermal comfort

LEED Example

Philip Merrill Environmental Center•Location : Maryland•Architect : Smith Group•Area : 2842 m2•Construction year 2000•Rating : Platinum

Energy•Sun collector for heating water• natural ventilation•30% renewable energy•Light control systems•Recycled material for ceiling ,walls ,isolation materials (materials like MDF)

LEED ExampleWater•Collect rain water for irrigation

Material and Recourses•R-value 20 for walls (skin design)•R-value 30 for ceiling

Indoor environment quality•Monitoring systems for CO2 in indoor environment

BREEAM ExampleBED ZED (100 eco home and office)•Location : South London•Architect : Bill Dunster Architects•Construction year 2002•Rating : Excellent

Energy•South orientation for homes • 88% saving heat energy•renewable energy PV cells•25% saving electricity •57% saving water heating energy

BREEAM ExampleWater•Water treatment system saving 50% of water resources (recycling)

Material and Recourses•Using recycled materials 15% and 52% local materials

Indoor environment quality•Monitoring systems for CO2 in indoor environment

Transportation•Walking distances•Cycling facilities•Saving 65% fuel

Results

•Energy – Site – Water – Indoor Environment (all systems)

•Pollution – Transportation - Emission – Management (in some systems)

•Emission/Pollution – Indoor Environment/Health (same meaning)

•Buildings type affect the rating scale

•more points means more sustainable building

•Climatic ,Economical and buildings types causes some changes in each rating system

•Design phase is very important
