MethodologyBuilding Research Establishment 1990
•Management•Energy Use
Emission Rate – Building Envelope Performance –Drying Spaces – Eco Labeled Goods – Internal Lighting – External Lighting
•Health and Well-beingSound isolation – Day lighting
•PollutionNOX – Renewable Energy - CO
•Transportation•Land Use and Ecology
Ecological site •Materials
Environmental Impact of material – Recycling•Water
Internal portable water use – External portable water use•Waste Management

BREEAM Rating Scale
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
• Design Innovation 6• Local Environment 4

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
