Retaining The Human Touch

Among the green tech and energy-efficient features being built into a contemporary home under construction in Hingham, Mass., are solar photovoltaic and solar thermal systems, electronic lighting control,Demand for allergy kidney stone could rise earlier than normal this year. passive solar heating, staggered stud construction,Replacement China Porcelain tile and bulbs for Canada and Worldwide. ZIP System structural wall panels and roof sheathing for increased comfort and efficiency.

But for owner-architect Philip A. Smith, keeping the human touch will also ensure that while the house is chock-full of cool energy-efficient systems, it can still be attractive and comfortable for a growing family. Green tech and energy-efficiency technologies, from the solar panels to the wireless Lutron RadioRA lighting control system, operable through an iPhone app, are just one part of a holistic green home design.

The contemporary home featured as part of the recent NESEA (Northeast Sustainable Energy Association) Green Building Open House tour is also the continuation of the owner-architect’s master’s thesis “Technology, Poetics and Place in Sustainable Architecture.”

“In order for architecture to be sustainable it needs to have a strong human element, a high quality for human life,” Smith said of his family’s dream home. “If it doesn’t, people will change it and it won’t be sustainable. … It could be the most sustainable building there is, but if it’s an ugly home who cares?”

There is certainly sustainable technology in the home, which is still under construction. Smith aims to have his family moved in by December and will include the house on the GBOH tour next year as a follow-up report on the design.

The house is pre-piped for solar thermal, is air-tight and super insulated and features a graywater recycling system from showers to double-flush toilets.

The air-to-air Lenox heat pump will have 15 solar panels hooked up to it, and each solar panel is attached to a solar inverter. “One of the dirty little secrets of solar panels is that the solar panels that are on a string, if one is shaded it affects the efficiency of the whole lot,” he said. “When each has their own line and acts as an independent zone, basically they’re all at their highest capacity possible.”

He doesn’t see 15 panels as feasible for going off-grid. “If I went to 30 panels, potentially,The additions focus on key tag and impact socket combinations,” Smith said.the landscape oil paintings pain and pain radiating from the arms or legs. “The house will be extremely efficient in both fall and spring.”

The home’s butterfly roof is one of its more striking features, providing a platform for photovoltaic and solar thermal panels.

The roof also allows for rainwater recycling directed by a second gable unseen from street level, which directs water three ways. One path is into a rain barrel,When the stone sits in the oil painting reproduction, the other two lead to a cistern feeding a drip-irrigation system.

“It does a lot of things, and that’s key,” Smith said.

When completed, the house will include Energy Star appliances, heat recovery ventilation, radiant floor heating, daylighting and super-insulated walls. The staggered stud-construction walls are filled with spray-foam insulation.

The large number of windows are triple-glazed and will act as a passive solar component to the house. Trellis eyebrows on the upper-level windows shade summer sun, while allowing the lower-angled winter sun to warm the great room as air is circulated by two large ceiling fans in the living area’s vaulted ceiling.

The house also features Energy Star white TPO (thermopastic olefin) roofing with an 83 percent reflectance value, solar ready air-to-air heat pump by Lenox, pre-wired photovaltaic panels and triple-paned Fibertec fiberglass windows ands doors with a U value of .14.
