This LEED Silver project in Evanston was developed as 4-story building with underground parking, with a total of twelve units. These apartment units are currently rented out and the building has achieved full occupancy, and recently earned LEED Silver certification from the U.S. Green Building Council.
One remarkable aspect of the building was a centralized geothermal systems that has one well field with pumps that bring the conditioned water to a heat exchanger, which is then pumped in a centralized loop to each dwelling unit. Inside each apartment is a mechanical closet featuring a power vented water heater and a hydronic-to-air forced air system. The remarkable efficiencies of the building resulted in average HERS ratings for the units in the upper 50's and low 60's. There was one apartment building that was a one-bedroom unit and got a "small home" penalty on the HERS rating that resulted in a HERS 69. Eco Achievers performed all LEED verification and performance testing services on the twelve units in the building.
The project team also took advantage of the landscaped area to install a fully sustainable drought-tolerant landscape design, and pursued the Outdoor Water Demand Calculator to achieve 10 points related to the reduced water use of the efficient landscape.
The developer of the project had this to say about Eco Achievers' role, "Thanks again for all of your efforts. It is a better building because of them." Becuase each unit had separate mechanical and water heating systems, this project achieved LEED certification under the lowrise LEED for Homes program rather than the LEED Multifamily Midrise rating system.
