Metro Caring – New Building

Metro Caring, a not-for-profit hunger relief organization that provides urgent food assistance and related services to individuals and families in need had outgrown its facility. Conditions were cramped, and parking was limited. A new ground-up 15,000-square-foot facility constructed on the existing site and an adjacent vacant lot consists of a reception area, welcome center, client care offices, administrative offices, boardroom, nutrition center with kitchen, and a “healthy living” space featuring a Client Choice Market. The market is completely stocked with shelving, reach-in coolers, and freezers, and has support areas for processing, warehousing, and a loading dock.

Multiple mechanical systems were evaluated, including evaporative cooling and mechanical cooling with either change-over bypass or VAV operation before deciding on a combination of VAV and constant volume. To meet a strict budget while limiting onsite water use, plumbing fixtures were specified at low flow rates to achieve a smaller standard tap size.

The Alliance Center – Renovation

Located in Denver’s Lower Downtown (LoDo) area, the Alliance Center is a six-story, 40,000-square-foot office building originally constructed as a warehouse in 1908. More than 100 years later, this historic structure was renovated into a sustainable, multi-tenant facility by its owner. With building improvements including a new digitally controlled HVAC system, energy-efficient fixtures and appliances, a lighting control system, translucent wall panels, sun shades, and a rooftop photovoltaic (PV) array, the two-year project transformed The Alliance Center into an extremely energy-efficient building. All onsite combustion of fossil fuels was eliminated, including the use of natural gas for heating, in favor of using solar or gridded electricity to meet all power needs.

To further decrease its carbon footprint, the Alliance launched its “DC project.” Devices such as computers, office equipment, and consumer electronics consume DC (direct current) power, generated by converting grid-supplied AC (alternating current) electricity to DC, an inefficient process. After exploring several options, 360 Engineering designed a system with the capacity to accept input from up to four different energy sources in addition to gridded electricity. By allowing the use of more solar (PV), wind, and any future clean energy technologies, this approach drastically lowered the Alliance Center’s reliance on the grid and further reduced its CO2 emission. During the project, 360 also collaborated with manufacturers to convert existing HVAC equipment to DC input, an effort that resulted in a research grant from Colorado State University to further study the potential energy savings of such HVAC AC-to-DC power conversions.

The facility has received several LEED certifications including Existing Building Operations and Maintenance LEED Platinum, Commercial Interior LEED Silver, and Dynamic Plaque LEED Gold. It was the first facility in Colorado and fifth in the world to recertify based on ongoing building performance evaluation.
