Sustainable MEP Design
Standards and rating systems for green-building systems abound. In the United States, ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, is a widely used standard providing minimum requirements for energy-efficient building systems in new and renovated buildings. The U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Green Building Rating System is the most prevalent scorecard used by those pursing green-building certification. Of the 69 total LEED credits available, approximately 25 percent are influenced by building-systems design.
Building-information-modeling BIM based design tools helped GNACE engineers to provide all ‘greener' parts of the building systems.
