Sustainability by..." A Synthesis of Procurement Approaches for High Performance Buildings
Sustainable design and construction has experienced significant growth in recent years. The predominant system in the United States for specifying and evaluating sustainable construction practices and materials is the Leadership in Energy and Environmental Design (LEED) rating system as prescribed by the United States Green Building Council (USGBC). Currently, research is lacking as to how owners communicate specific sustainability objectives to designers and constructors. Furthermore, it is unclear what approaches owners utilize for differing delivery methods. This study examines 92 recent projects of varying delivery methods, collectively representing over $2.2 billion in vertical construction from 2006–2009. The objective is to determine current delivery and procurement trends specific to sustainability. A content analysis methodology was used to examine and codify specific language and techniques used in procurement documents for each project. This paper presents the resulting framework of four owner approaches for specifying sustainable goals: 1) sustainability by competition; 2) sustainability by specified level; 3) sustainability by qualifications only; and 4) sustainability by reference. Within this framework, trends are discussed across all delivery methods as well as trends specific to individual project delivery methods.
