Sustainable design standards

Design Standards, Reference Standards and Performance Standards are familiar throughout business and industry, virtually for anything that is definable. Sustainable design, taken as reducing our impact on the earth and making things better at the same time, is in the process of becoming defined. There are also lots of well organized specific methodologies that are used by different communities of people for different purposes

Design Standards

One of the better know is LEED Leadership in Energy and Environmental Design which uses a diverse group of hard measures of environmental quality and impacts to define a holistic approach to sustainable building and assign ratings to individual projects.

Sustainable design is really just a more determined effort to consider the whole range of impacts on our environment in making any decision. A more complete design guide, guided more by whole project impact measures, is the model offered by the US cooperating agencies in the "Whole Building Design Guide". This kind of broad institutional effort is supported by a variety of code and performance based standards such as the proposed ASHRAE 189.1 for engineering systems design.

Several organizations have developed their own ways of setting goals for energy reductions, such as Architeture 2030 and for qualifiying performance toward them such as Cradle to Cradle

Design Methods

Developing real methods for how to discover the design opportunities that would allow you to meet or exceed the standards was one of the objectives of the environmental design movement in architectural schools in the 1960's and 70's, but though some of the issues introduced then are still an important part of the process, not much actually changed about the methods of design. Now with the combination of many more interactive tools and much higher stakes in the outcome, and long gestating rethinking about natural systems in general, a dramatic new revolution in methodology seems inevitable.

BIM (building information modeling) allows designers to work with many remote consultants on the same data file that represents all the decisions being made by the team. That same file is available to the climate and energy and environmental impact analysis and cost analysis tools and consultants,... and of course to the prospective contractors and the regulators. Along with this new integrated access to the model there in needed a new way to integrate the conversation of so many people, each with some interest in reviewing each other's comments on the progress with the central design model. That is likely to involve development of Wiki tools for the process. One such very early impliementation of a Wiki SD tool called "4Dsustainability"organizes the project design evolution around the general learning process of how you define the problem by exploring it's environment, and following that through the project.

The main difference between sustainable design methods and conventional design is incorporating the entire environment of the project's stakeholders on the design team, essentially, and that calls for new ways to explore connections and for more people and perspectives to be taken into account. Other methods that recognize this requirement are the "AIA SDAT" (sustainable design assessment team) program and the "Scenarios for sustainability" process design tools.
