Lime Green is a philosophy of increasing the efficiency and performance of a building. You do not necessarily need to certify your building to be "Green". Increased performance leads to lower operating costs, healthier environments, and occupant well being.
Sure, we believe in Certifications, but that's typically more for marketing than performance. And if that is within your budget or goals, we'll be happy to help you.
However, we encounter far more clients that want, or need, to "Lime Green" a facility through sustainable or "Green" practices in order to lower the operating costs of that facility.
