Federal & State Incentives for Renewables & Efficiency (U.S. Department of Energy)
This is a comprehensive source of information on federal, state, and local incentives and policies that promote renewable energy and efficiency.

Greening our Built World: Costs, Benefits, and Strategies (Greg Kats)
Using sophisticated modeling techniques, the study analyzes the costs and financial benefits of building green on both large and small scales, and addresses the role of the built environment in reducing carbon dioxide emissions.

Life Cycle Cost Analysis (Whole Building Design Guide)
Life-cycle cost analysis (LCCA) is a method for assessing the total cost of facility ownership. It takes into account all costs of acquiring, owning, and disposing of a building or building system.

Nature and Consumer Environments (Nature Within)
A series of studies shows that consumer behavior is positively influenced by the presence of trees. Adding trees to the urban environment benefit cities, merchants, and consumers. 

Assessment Tools

Building Retrofit: Simplified Lighting Energy Savings Estimator (Sustainable Cities Initiative)
This tool provides an estimation of the energy and cost savings as well as the potential reduction in carbon dioxide emissions and coal consumption that can be achieved by switching to higher efficiency lighting.

Energy Saver (U.S. Department of Energy)
A whole set of resources from the Energy department provides homeowners with tools for maximizing home energy savings. Also worth checking out are the department's "home" resources.

Energy Star ® Cash Flow Calculator (Sustainable Cities Initiative)
This calculator is ideal for users interested calculating whether and how to invest in Energy Star equipment.

Heating and Cooling Your Home for Less (U.S. Federal Trade Commission)
A simple guide to local options for improving home energy efficiency.

Heating Fuel Cost Calculator (Building Green)
This web calculator allows individuals to compare the cost of different fuels by selecting a fuel, entering your local price, and choosing a heater and distribution system.


Green Building Finance (Council of Development Finance Agencies)
This site provides a list and summary of tax credits and financing opportunities available for green building development.

Modeling Software

Building for Environmental and Economic Sustainability (BEES) (National Institute of Standards and Technology)
BEES measures the life-cycle environmental and economic performance of a site by considering acidification, air pollutants, ecological toxicity, eutrophication, fossil fuel depletion, global warming, habitat alteration, human health, indoor air quality, ozone depletion, smog, and water intake.

Case Studies

Center for Health and Healing, Portland, Oregon
This case study highlights the sustainable design principles used in this 16-story, 400,000 square foot, medical office and wellness building. It provides a comprehensive overview of its greening strategies and an analysis of its “greening costs” as well its projected utility savings.
