Patterns
Construction
projects occur in a series of chronological steps. The best steps to take in the design,
development, and construction of affordable, sustainable housing can be expressed as a set
of "patterns.” The pattern metaphor is often used in design to describe a
desired end result without limiting the possibilities for achieving that result.
In this set
of patterns, each pattern explains a particular element of sustainable design that would
be a desired end result for a project. Conforming to a pattern can be accomplished by
acting on specific recommendations tailored to that pattern.
Each
pattern can be employed singly to improve the performance of a house or the efficiency of
the construction. However,
when all patterns are applied together, in a holistic approach, the net effect is
multiplied, and a sustainable house is produced.
