Extract

Green rating tools are contributing to move the agenda of sustainability to a central role in the design and operation of office buildings. However, research needs to ascertain if certification sys-tems also contribute to improved user satisfaction. Synthesising re-search by the authors, this paper analyses a subset of the Center for the Built Environment database to investigate if LEED certification leads to higher, equal, or lower user satisfaction, and examine the im-pact on satisfaction of factors distinct from conventional IEQ parame-ters. The results show that occupants of LEED-rated buildings are equally satisfied with building, workspace, and various IEQ parame-ters than users of non-LEED buildings, independently of office type, spatial layout, distance from windows, building size, gender, age, work type, and working hours. However, tendencies suggest that oc-cupants of LEED buildings may be more satisfied with air quality and more dissatisfied with amount of light, and that the positive value of certification may decrease with time. Also, LEED-rated buildings may be more effective in delivering satisfaction in open rather than in en-closed offices, and in small rather than in large buildings. Deeper con-sideration of user needs is required to ensure that buildings designed and operated for green rating standards also enhance IEQ satisfaction.
