In my city, the people I was with and I have genuinely strict protocols for any modern building that is added to the current grid, and this is because our city has genuinely firm laws that truly work to help our entire county be green as well as also be better to 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 no easy feat to achieve; this requires the building to have a number of energy efficiency projects included in the overall design. The building should work to use as several recycled materials or otherwise hazard free materials as much as possible, with the required number according to the energy efficiency projects team at a minimum of 50%, in addition to this, the building must have its utility systems set according to LEED standards as well, which requires efforts to be made that work with the environment rather than against. As well, one such respected aspect of commercial building energy conservation is a water recycling system. This plan works to harvest rainwater every day, which is then used to flush toilets… By bringing in rainwater to complete these tasks, the building therefore uses far less fresh water, and a water recycling plan can similarly be used to harvest rainwater water as well as turn it into potable water, which means water that is safe for everyone to drink. These energy efficiency projects add a large price tag to a commercial building, but they are particularly worth the cost as they both save currency as well as save the environment too.
