Improving the built environment through research, sustainable design and technology.

Welcome to Steven Winter Associates, Inc. We are proud of the reputation we have built as one of the nation's most respected and knowledgeable firms in research, design and consulting for high-performance buildings.

Our reputation is built from 35+ years of experience offering our clients leading edge technology, research and development.

Long before the rest of the world caught on, we took the “whole building” approach to incorporating energy and resource efficiency measures into residential, commercial, educational, institutional and community building projects. The range of services we offer reflects this approach; whether its accessibility issues, challenges specific to multifamily buildings, or building homes that use zero net energy.

Sustainable, or green, is no longer just a trendy buzzword. Today, it represents a critical turn in public and corporate awareness that is good for the environment and good for business.

Ultimately, our work is about reducing the impact that we have on our environment by harnessing the power of science to create buildings and communities that use less and perform better over the life of the structure.
