Creating a more sustainable world - one project at a time

MHA is committed to integrating deep sustainable design into every project.  Through an integrated design process, years of green experience, and continuous research on newly available technologies, we can provide truly high-performance buildings cost effectively. Our years of green construction administration have also given us the experience to commission new green technologies such as air barriers, exterior insulation, air to air heat pumps, and daylight harvesting.
