1960's Mid Century Modern

Classic Mid Century Modern Gets Complete Makeover for Ultra-Efficiency & Full Accessibility

The Problem

In addition to the home’s ability to meet Caffrey’s needs with features such as lowered light switches and outlets, automatic faucets, and accessible cabinets with touch-release doors, the HVAC system had to be state-of-the-art. Progressive weakness brought on by muscular dystrophy can affect the muscles associated with breathing, and patients can become susceptible to allergens and other air impurities, so the choice of HVAC system was just as critical to the home as its accessibility. Additionally, it was important that the new HVAC system match and not detract from the home’s original Mid Century Modern aesthetic and charm. The house’s exterior brick walls and low profile roof design left absolutely no room for ducting, requiring an alternate placement to feed conditioned air to various rooms. A tall order even though the renovation design called for the creation of a new basement. Also, with so much money being invested in the home’s reimagining, the family wanted a central heating and cooling system that delivered superior indoor air quality (IAQ) and was ultra-energy efficient, sustainable, and dependable for years to come. Finding a solution that met all of the Werner-Lester family’s needs and wants meant going beyond the usual HVAC approaches.

The Solution

Michelle and Billy worked with the show’s mechanical engineering team to come up with an indoor comfort solution that would meet their demands. They settled on a geothermal water-to-water heat pump as the source that would deliver the required heating and cooling energy to feed both the indoor comfort and potable water systems. This required the drilling of four 500-hundred-foot-deep wells spaced twenty feet apart in order to tap into the constant 50°F available in the earth and transfer it to the home through a closed-loop system. When it came to the air distribution side of the HVAC system, the team agreed that only the small duct Unico System would fit into the home design, match its finished aesthetic, provide the requisite IAQ, and deliver the desired comfort and efficiency. The team chose Boston-based Back Bay Mechanical as the HVAC experts to install the necessary heat pumps, buffer tanks, The Unico System, and all the piping and wiring required to link the various systems. Back Bay Mechanical is no stranger to The Unico System having installed it for decades, including a project that converted a 19th century church into high-rise condominiums. James Bouchard, owner of Back Bay Mechanical, had an ingenious method for placing The Unico System ducting. Trenches were dug through and under sections of the home’s existing slab foundation. In these, spiral-bound round metal structural ducting was set and completely encapsulated in blown-on, expanding cellular insulation. The ducting is strong enough to withstand being entombed under the home while the insulation ensures that air will not escape, and water will not intrude into the ducting, giving it a life expectancy beyond multiple decades.

The Results

The Werner-Lester family is thrilled with their new home. By all accounts, they’ve completely settled in and are making the most of their new living space. While there will undoubtedly be challenges in facing Caffrey’s illness, the family will be able to do so from a modern, energy efficient, and comfortable environment.
