Many green building designs, strategies, materials and practices can and do save money because they generally reduce energy costs, labor costs, and medical costs now and in the future. Green Buildings last a longer time, require fewer resources to develop, consume little energy, and are very cost efficient to heat and cool. Resale values of green buildings are often greater than those that are conventionally built. Green products may cost more initially, but more often than not, if you factor in life-cycle costs as well as human health concerns, building with green materials makes good financial sense.
