LEED (Leadership in Energy and Environmental Design) certification at various certification levels is the most widely used rating system for green buildings worldwide. Accredited LEED professionals are available to commission a new or existing building by specifying improved mechanical systems, fixtures, and building materials. We help implement Clean and Renewable Energy Technology (CRET) and other green initiatives such as the addition of a green roof with cistern water collection. We seek to achieve a state-of-the-art building envelope and facade that is aesthetically appealing and high-performing. Sustainability in the built environment focuses on sustainable BD+C & O+M. LEED is the benchmark for building owners desiring 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 like 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 passive heating (passive solar design for solar heat gain) for a building.
