LEED stands for Leadership in Energy and Environmental Design. LEED certification, at various certification levels, is the most widely used green building rating system in the world. Accredited LEED professionals are available to commission a new or existing building by specifying improved mechanical systems, fixtures, and building materials. We help to implement Clean and Renewable Energy Technology (CRET) and other green initiatives like adding a green roof with cistern water collection. We seek to achieve a state-of-the-art building envelope and façade that is aesthetically appealing and high-performing. Sustainability in the built environment focuses on sustainable BD+C & O+M. LEED is the benchmark for buildings looking to lower energy and water costs to net zero, or, possibly, net positive where you receive money back each month from your energy provider. We suggest ways shading can be provided by natural landscaping or building elements such as awnings, overhangs, and trellises; incorporating skylights for daylighting; and employing a building design approach that focuses on passive cooling (ventilation as a natural cooling strategy) or heating (passive solar design for solar heat gain) for a building.
