Ratings, Awards and Recognition

Ratings:

Weinberg Commons has been completed and has now been occupied for 2-3 months depending on which building of the three. We have not yet collected any energy use data.

The Project was pre-certified through the PHIUS+ program and is now undergoing final certification.

Other Awards:

Award for Innovation & Entrepreneurship in Real Estate - awarded by the A. James Clark School of Engineering, the School Architecture Planning and Preservation, the Robert H Smith School of Business, and the Colvin Institute of Real Estate Development of the University of Maryland.

The project leverages affordable housing tax credit financing to provide affordability and financial stability for families.  On top of the low base-rent, the project developer will further reduce cost to residents by returning all but a small fraction of the utility allowance to the occupants, achieving the lowest possible total cost of residency through energy savings.  Energy demand reductions approach 100% through meeting the PHIUS+ energy standard and the provision of on-site renewables.

The project involves (3) twelve unit, three-story buildings to serve this population.  At completion, (36), two-bedroom, 675 sq. ft. apartments and an on-site, 672 sq. ft. Programmatic Space including computing workstations and conference space have been provided.
