Abstract [en]

Certification systems for sustainable neighbourhoods started to emerge around a decade ago. This study analysed the content, structure, weighting and indicators of two established certification systems for sustainable urban development - BREEAM Communities and LEED for Neighborhood Development. Several limitations of these systems were identified: both have a bias for procedure and feature indicators over indicators that assess actual performance; performance demands are set according to a relative understanding of sustainable development; the focus is on internal sustainability, while upstream and downstream impacts of construction are disregarded; the number and distribution of mandatory issues do not cover essential sustainability aspects; and the disproportionately large number of non-mandatory issues makes benchmarking difficult and signals that sustainability aspects are exchangeable. Altogether, this means that an area can be certified without being sustainable. Moreover, the lack of continuous development of certification requirements in the systems means that they risk exerting a conservative effect on urban development, rather than pushing it forward.

Abstract [en]

This thesis explores Neighbourhood and Building Environmental Assessment Tools’ (NBEATs’) function as assessment tools and decision support, and their relation to environment, architecture and architects. This is done by analysing, testing, and discussing a number of NBEATs (LEED-NC, Code for Sustainable Homes, EcoEffect, LEED-ND, BREEAM-C, and ENSLIC-tool), their manuals and use. Moreover, professionals’ (architects’) self-rated opinions regarding use and knowledge of NBEATs and environmental aspects are surveyed.

Similarities and differences in NBEATs are found regarding: content, structure, weighting and indicators used. Indicators distinguished as procedure, performance and feature are used to varying extents to assess social, environmental and technical aspects. NBEATs relation to environmental sustainability has limitations due to: non-transparency, tradable indicators, relative measures, low criteria levels, limited life cycle perspective, and exclusion of relevant environmental aspects, such as embedded toxic substances, nutrient cycles, land use change, and ecosystem services. Ratings and architecture are influenced by NBEATs in varying ways. Higher criteria levels would probably increase their impact on architecture. Thus more research regarding NBEATs and links to architectural design, theory and practice is welcomed.

There is limited use of NBEATs as decision support in early design phases such as in architectural competitions. Architects rate the importance of environmental aspects high, but few rate their skill in handling environmental aspects high. This calls for increasing knowledge and know-how of environmental strategies and solutions among architects and adaptation of NBEATs to early design processes. The values NBEATs reflect and the values we want them to create is also important. To support ‘environmental’ architecture, an increased socio-eco-technological system perspective is put forward, and other measures besides NBEATs are needed.
