The Cool Colors Project (Lawrence Berkeley National Laboratory)
Painting roofs white and other light colors can reduce roof temperatures and energy and cooling costs.

Green Building Sustainable Sourcebook: Green Building Design Tools (Austin Energy) 
An in-depth online resource covering community, water, energy, health & safety.

Green Design Resources (BuildingGreen)
The creators of the GreenSpec product directory offer set of articles covering resources and materials, energy, site and water, and other areas.

Sustainable Building Toolkit (California Sustainable Building Task Force)
This toolkit offers case studies, fact sheets, studies and performance standards.

Whole Building Design Guide: Low Impact Development (National Institute of Building Sciences)
This site explains the value of  Low Impact Development (LID) and why infrastructure projects should implement LID practices.

Rating Systems

BRE Environmental Assessment Method (BREEAM) (BRE Global)
The most widely used environmental assessment method for buildings worldwide.

Code for Sustainable Home (UKGBC)
The Code is the national standard in the UK for the sustainable design and construction of new homes. "The Code aims to reduce our carbon emissions and create homes that are more sustainable."

Comprehensive Assessment System for Built Environment Efficiency (CASBEE)
A global green building rating system developed in Japan.

Energy Star (U.S. Environmental Protection Agency / U.S. Department of Energy)
Energy Star is a "national mark of excellence" in building performance. Both home and commercial buildings can apply to become an Energy Star facility. Energy Star's Target Finder can be used to set energy performance targets.

GBTool (International Initiative for a Sustainable Built Environment)
Developed during the international green building challenge process, GBTool is a green building assessment framework.

Green Globes® (Green Building Initiative) 
This rating system offers opportunities for recognition and certification in the design, construction, and/or operation of commercial buildings.

LEED Rating Systems (U.S. Green Building Council) 
A third-party certification program and the nationally accepted benchmark for the design, construction and operation of high-performance green buildings. Green building-related LEED Rating Systems include: Commercial Interiors, Core & Shell, New Construction, Schools, Healthcare and Retail, Existing Buildings and Operations & Maintenance.

Living Building Challenge 2.0 (International Living Building Institute) 
One of the most difficult green building standards to achieve. Reaching "Living Building" certification, which involves success in seven performance areas (including site, water, energy, health, materials, equity and beauty) requires investing in a comprehensive green building design and development process. 

National Green Building Certification (National Association of Home Builders)
The four threshold levels - Bronze, Silver, Gold, and Emerald - allow builders to achieve entry-level green building, or the highest level of sustainable "green" building incorporating energy savings of 60 percent or more. Single-family & multi-unit homes, residential remodeling projects, and site developments are all covered in the standard.

Assessment Tools

Durable Goods Disposal Calculator (Environmental Protection Agency)
The calculator estimates GHG emissions benefits for recycling, landfilling and combustion of 14 typical household durable goods (refrigerators, freezers, dishwashers, gas and electric stoves/ovens, washers and dryers, televisions, VCRs, microwaves, carpets, cars, tires, and computers).  

Lighting Energy Use Worksheet (Sustainable Cities Institute)
This user-friendly Excel worksheet offers a simple, yet effective tool for identifying and tracking lighting equipment in all parts of a building. In addition, the worksheet will calculate the energy used for lighting needs assessed in a facility.

Power Smart Pricing (Center for Neighborhood Technology)
A real-time electricity pricing device that aids homeowners and utility companies in reducing electricity usage during peak hours.

WaterSense (U.S. Environmental Protection Agency)
The EPA approves water-efficient home products.


Environmentally Responsible Design and Construction (Building Green) 
A checklist for green building design.

Green Building, Remodeling, and Development (National Association of Home Builders) 
Resources include the ICC-700 National Green Building standard.

Modeling Software

EnergyPlus (U.S. Department of Energy)
Originally based on BLAST and DOE-2, EnergyPlus includes many innovative simulation capabilities.

Building Energy Software Tools Directory (Lawrence Berkely National Laboratory) 
This directory offers information on 382 building software tools.

Case Studies

AIA COTE Top Ten Projects
Each year, the American Institute of Architects' Committee on the Environment (COTE) gives awards to leaders in green building design.

Chicago City Hall, Chicago
As part of an E.P.A. study and initiative to combat the urban heat island effect and to improve urban air quality, Chicago City Hall was renovated with a 38,800 square foot green roof.
