Costs Of Greening Research Labs

Davis Langdon also studied the impact of climate on the costs of a research lab. Costs ranged from 2.7 to 6.3 percent premium for a LEED Gold project, and 1.0 to 3.7 percent for a LEED Silver project (the study assumes the same design was constructed in various cities at the same time).

The key cost message to owners and developers (and design and construction teams) is that sustainability needs to be a "program" issue, that is, it needs to be embedded in the goals of the project and not treated as an add-on cost element. This conclusion is not just a matter of semantics; it goes to the very heart of the question, "what is the purpose of this building or project?" If sustainability is not a core purpose, then it's going to cost more; if it is essential to the undertaking, then costs will be in line with non-green buildings of the same type.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
