Josephine Commons – Phase I

455 N Burlington Ave
Lafayette, Colorado

Type: Multi-Unit Residential

Owner: Boulder County Housing Authority

Architect: HB&A

Project Summary

Phase I of the Josephine Commons low-income and senior housing residential development encompasses approximately 3.7 acres and includes a three-story, 70-unit senior apartment building, two single-story duplexes and associated parking lots, driveways, landscaping and supporting utility infrastructure. The utility infrastructure includes the majority of the utility main lines, which are also used to support Phase II developments.

The 85,800 sq. ft. senior building includes a large community dining and events room, a commercial kitchen, a small meeting room on each floor, a library and a leasing office. There are two (2), one-story duplexes, situated primarily along the south edge of the project site that add another four senior units for a total of 74 units. The duplex units were constructed off-site by a modular manufacturer. Each duplex is 1,800 sq. ft. and includes a 1,800 sq. ft. basement.

The site and structures incorporate multiple renewable energy technologies. All unit mechanical systems consist of individual heat pumps serviced via a vertical ground source geothermal bore field. The 50 geothermal bore holes were installed over and through existing coal mine shafts. The senior building rooftop photovoltaic system includes a ballasted array of 98KW with an additional 30KW installed on the carport parking structure. All units are equipped with water conserving appliances and fixtures, efficient lighting and individual electrical submeters. The sustainable features resulted in an approximate 30% savings from baseline ASHRAE 90.1. The project meets the Green Communities Criteria Checklist as required by Colorado Housing Finance Authority (CHFA).
