In our city, each of us have extremely strict protocols for any current building that is added to the new grid, however this is because our area has easily firm laws that task to help our entire county be green and better for the environment. Every building that is constructed or even a renovation if it involves gutting more than 80% of the building has to be built to LEED certification standards, and LEED is truly no easy feat to achieve; In regards, this requires the building to have a number of energy efficiency projects included in the overall design. The building should first and foremost use as multiple recycled materials or otherwise conflict free materials as much as possible, with the required number according to the energy efficiency projects team at a minimum of 50%, and, in addition to this, the building must have its utility systems set according to LEED standards too, which requires efforts to be made that the upgrades work with the environment rather than against it. One of these aspects of commercial building energy conservation is a water recycling system. This plan works to harvest rainwater throughout each day and night, which is then used to flush toilets. By bringing in grey water to complete these works, the building uses far less fresh water as a result; A water recycling plan can also be used to harvest grey water and then turn it into potable water, which means water that is safe to drink. These energy efficiency projects add a sizable price tag to a commercial building, but they are really worth the cost as they both save currency and save the environment.
