WHY BUILD GREEN? Infographic explaining green building’s many benefits

London, England building with grass growing up outer walls - Why build green?

Green building is smart building. Aside from their obvious benefit to the environment, green buildings deliver financial savings, are more comfortable, healthier, return higher productivity rates and have higher resale values. See this infographic for a quick look at why building green makes so much sense. And for a more detailed understanding of green building refer to the second page of our green building basics guide: Why build green?

Why build green? [infographic]

The environmental impact of buildings

  • 50% of natural resources
  • 25% of landfill waste
  • 12% of water consumption
  • 10% of airborne particulates
  • 35% of greenhouse gases
  • 39% of energy use


Conventional home = Average building costs of $125/sq. ft. = $150,000
Annual energy costs = $3000

Green home = Average building costs at a 2% premium = $153,000
Annual energy costs = $2250 (25% savings)

Average payback period = 3 years (without government rebates, 4 to 5 years)

Perception vs. reality

LEED-certified buildings cost on average 1 to 2 percent more than comparable conventional buildings, yet public perception is quite a different thing.

When asked “if there is a significant cost difference between green building and standard building products and practices?” building professionals answered:

62% – Yes
26% – No
12% – Unsure

Other financial benefits

Property value – green buildings show higher property values and average sale price increases of more than $20 per sq. ft.

Decreased demand on infrastructure – high performing buildings demand less energy and water, which decreases the strain on common resources and allows infrastructure capacity to extend farther.

Increased productivity and attendance – productivity gains of 2-10% and a reduction of 35% for absenteeism have been reported.

Improved sales – 40% increase in sales reported in buildings that use skylights rather than electric lighting.

Gas savings – A green built community can result in annual gas savings of as much as $1000 per house-due to proximity to necessary infrastructure.

Investment decision – Leed buildings have an ROI of 15 to 20% just based on energy efficiency measures.
