Green building design and construction creates healthy, resource-efficient structures that often yield superior economic and environmental benefits.

The Sustainability Cycle

Sustainable design and construction is a deeply integrated process that begins at project conception. Successful initiatives take a high level of involvement throughout the project lifecycle. That deep integration makes Haskell’s design-build methodology, built on an integrated project delivery, ideally suited to creating responsible, sustainable projects that enhance our communities.
