“The county had undertaken a big redevelopment process for this community, developing a new planning tool called the Nauck Village Center Action Plan (in 2004),” said John Welsh, AHC director of its multifamily division. Constructing the nearby 94-unit Shelton in 2007, winner of two AIA/DC awards and one Arlington County Design Award, Welsh and colleagues soon entered into a dialogue with the church about the church-owned parcel that would eventually become the Macedonian.
Offering development expertise and acquiring funding in the form of $3.9 million in VHDA tax-exempt bonds, $2.7 million in tax credit equity, $550,000 in deferred development fees, a county cash flow note of nearly $3.5 million, and TCAP funding of about $2.4 million, AHC teamed with Bonstra Haresign Architects and Bozzuto Construction to create a multi-use structure that also designates 2,000 s.f. of commercial space for shops and the church-affiliated CDC, and acts as an incubator for several area start-up businesses.According to Thomas Wallinga, AHC construction manager and former architect with Bonstra Haresign, while energy efficient lighting and appliances were standard on the path to EarthCraft certification, additional unit sealing to prevent energy leakage was high on the construction agenda, as were low-emissivity double-pane windows and low-flow fixtures.
"But the most unusual thing we did was actually the mechanical system,” Wallinga said, identifying a Mitsubishi variable fluid flow (as opposed to air flow) system: the CITY MULTI R2-series. Used largely in Europe and Asia, up to nine units operate off of one condenser in a two-pipe system, according to Wallinga. In this respect, energy is shared between individually-metered units so that one tenant can use heat and another air conditioning, simultaneously, a common practice in transitional seasons like spring and fall. “It balances things out at a much higher efficiency level than typical heat pumps,” he explained.Per Welsh’s description of the process, the Mitsubishi product works like an old hydronic system but utilizes Puron, an environmentally safe refrigerant. He explained that the system is relatively new in the U.S., has not been used residentially, and there is no existing method to determine a SEER (seasonal energy efficiency ratio) rating.
be studying the product for testing and rating purposes. In order to meet aesthetic standards as well as sustainable design goals, the team located nine Mitsubishi condensers in the ventilated parking garage, instead of as eyesores on the lawn or the roof, in part to showcase a modular “live roof” system that includes concrete paver patio space for residents. Featuring sedum, large individual trays of plantings sit atop a secured, reflective, watertight roof membrane to reduce storm water runoff. Green carpeting suffuses the patio area to the parapets, with stone edging, so the roof membrane is not visible.A floor for more
“We wanted something that looks better and is more durable in terms of tenant changeovers,” Wallinga said, citing the use of Amtico flooring. A vinyl product that is “heavy duty” but aesthetically imitates fine wood, the 4x36-ft. strips resemble a warm cherry floor, the results achieved by photographing wood and transferring to the vinyl printing process for a plank look. While bedrooms are carpeted, kitchens, living rooms and hallways utilize Amtico, with any damage easily rectified and expense mitigated by replacing just a single strip, when necessary.

“The building is also smoke-free—you can’t even smoke on the balconies” which is what the church wanted in its pursuit of a healthier environment, Welsh explained. “And by cutting the use of carpeting by 50 or 70 percent, we’re cutting down on allergens for a better breathing environment, not to mention decreasing maintenance costs and landfill impact by having to rip it out when someone moves out.
Five designated ADA units have requisite roll-under kitchen and bathroom cabinets and roll-in showers, with audio-visual adaptation if a tenant is hearing or visually-impaired, but all other units are partially adaptable if necessary. Noting 529 people had made inquiry about the building, Welsh said 64 applications had been received to date and about a dozen residents have moved in.
