Glumac provided MEP engineering and Energy Analysis for this 22,500 sf, three-story workforce housing project.

The owner had ambitious energy and cost efficiency goals for this project, including Net Zero Energy, an energy use intensity (EUI) one third of a standard building, and an aim of constructing the project for under $100-per-square-foot.

To help achieve these goals, Glumac facilitated securing a large state and utility incentive of $125,000, which represented 5.5% of the total construction budget.

The vision for this project was to show that highly sustainable design can be extremely affordable to construct and manage. By building energy efficiency into the building the inherent cost savings can be passed on to the tenants – a crucial factor when developing housing with affordability in mind.
