IgCC and ASHRAE Standard 189.1 Technical Provisions

Share This

Course Length: 3 hours

The IgCC and ASHRAE Standard 189.1 Technical Provisions course covers how ASHRAE/ICC/USGBC/IES Standard 189.1, Standard for the Design of High-Performance Green Buildings, forms the technical basis for the International Green Construction Code® (IgCC). The code provides the minimum requirements needed to achieve high-performance green buildings and was developed to provide a balance of environmental factors involved with designing, building, and planning for the operation of buildings. This course provides a detailed look at the technical standard and its application as a building code, including a description of key requirements contained in the IgCC and ASHRAE/ICC/USGBC/IES Standard 189.1 on the topics of sites, water, energy, indoor environmental quality, and materials. Consulting engineers, architects, facility managers, contractors, and code officials will learn to distinguish between the two compliance path options (prescriptive and performance) and their associated provisions in the IgCC, as well as how to apply these paths in design. Attendees will also be able to differentiate the code and standard from other green building certification systems.
