2012 Solar Home Tour - Middle Peninsula, Saturday, 6 October
1M. Crockett Home -
A net-zero solar home featuring passive solar design, solar hot water, and a grid-connected photovoltaic system. Architectural features include extensive south-facing windows, carefully sized roof overhangs, integrated thermal mass, passive cooling elements, northern buffer spaces, substantial insulation, and an open floor plan. The solar hot water system was installed 27 years ago when the house was built, with the original hot water tank and three of the original collectors still in service; the fourth collector was replaced in 2011 after 26 years of service. The system provides nearly 100% of the household hot water needs from June through September. A 6.6 kW net-metered Westinghouse Solar photo-voltaic system was added in two phases in November 2010 and July 2011 and is now producing more power on an annualized basis than the household consumes.
2M. Teschner Home -
The 3800 square foot house is a passive solar design, with approximately 360 square feet of windows on the south side, positioned 6 degrees off magnetic south for a precise south facing orientation. Overhangs above the windows are calculated to keep the sunlight out during the summer and in during the winter. Clerestory windows allow sunlight to enter the cathedral ceilings of the second story rooms on the north side of the house. Brick floors on the first and second story of the south side of the house serve as the thermal mass, which heats during the winter and cools during the summer. Awning windows near the floor are opened at night. Cool air is drawn across the brick floor by a large whole house fan located in the attic. The floors are constructed of double 2X10's, 12 inches on center. The exterior walls of the house are constructed of 2 X 6's, and the roof of 2X12's, filled with standard insulation. A heat exchanger is used during the winter to bring fresh air into the house without a significant loss of heat. The thermal mass and HVAC system are within the insulated space. The house has a 5 ton geothermal heat pump for additional heating and cooling. The geothermal system draws water from a single 550 foot well. Water temperature coming from the well is 69 degrees Fahrenheit. The Virginia Department of Geology suggests that the high ground water temperature is due to the radioactive decay in a granite formation in the earth below the well. The Virginia Department of Mines, Minerals, and Energy (DMME) is mapping a geothermal profile of the state based, in part, on well water temperatures. The exit temperature of the water coming from the heat pump is 88 degrees when used for cooling. The same differential of entering and exiting water temperatures applies in winter. A heat recovery system in the heat pump heats the water in the hot water tank when the heat pump is used for cooling. The heat pump is manufactured by Florida Heat Pump (www.fhp-mfg.com). There is a wood stove in the first floor living room whose ceiling is the height of the house, where a return is located that draws hot air back into the air handler during the winter. Tall trees on the West side shade the house during the summer. There are seven ceiling fans in bedrooms, kitchen, and in a screened-in porch on the north side.
The architectural style is utilitarian, following
the principle of form follows function. The detached garage/apartment is
the same basic design with shed roofs and clerestory windows, but
without passive solar heating.
Passive solar allows for other architectural possibilities
particularly if the solar gain is isolated, as in an atrium, rather than
distributed across the structure.

3M. Hudgins Home -
For the owner/architects reduce, reuse and recycle was a guiding principle when renovating and adding to a waterfront 1950’s Cape Cod cottage. Original redwood siding, poplar roof sheathing, old growth pine rafters/joists, and original oak flooring were among parts of this home salvaged and incorporated into the new structure in creative and unexpected ways. New green innovations include passive cooling; a closed loop geothermal HVAC system; an EPA certified wood burning fireplace; solar hot water system; an Energy Star® cool roof; hybrid closed cell sprayed polyurethane insulation throughout the house; Energy Star® appliances and light fixtures; and WaterSense plumbing fixtures. Rain barrels and a modular green roof are also part of the home.
4M. White Home (AKA Casa Agua) -
We began constructing our green house by installing a “living
shoreline” all around the property to protect Woodas Creek, which is an
extension of the East River. An oyster reef, coir logs and
marsh vegetation were installed and planted. Eventually this will
create a 10 foot buffer to filter any runoff.
5M. Bond Home - Solar PV
We recently built our home and went with options that allowed our solar array to function best. We installed all high efficiency appliances including a tankless hot water heater. We included foam insulation, high efficiency windows, lower ceilings, low flow toilets, and automatic shut off lights in closets. The most environmentally friendly part of our home is the solar panels. The array consists of 20 photovoltaic panels that are capable of producing 4.7 kilowatts per hour in the best conditions. Solar Services, in Virginia Beach installed the panels and inverter they were wonderful). So far our highest power bill was 20.00. This was in the hottest weather we have experienced this year. They were installed in April.
6M. Dezern Home - photovoltaic solar system
This home has a 9.4 kilowatt ground mount photovoltaic solar system consisting of forty (40) Sharp 240 volt solar panels installed with forty (40) Enphase micro-inverters connected to the back of the solar panels that are in turn connected to the electrical service panel box via #4 wire and two 50 amp circuit breakers. The installation was completed in 2011 by Royer Technical Services, Inc. The installation includes a communications system that provides reports of past and present power and energy production by the solar system via an internet connection with the manufacturer. Electric bills have been substantially reduced. Specific information will be available to visitors.
7M. Senyk Home -
Originally designed and constructed as a "solar home" in 1980-1981
using 1970's technology:
8M. Tolson Home - 7 KW PV array and 4 KW solar hot water system
9M. Middle Peninsula Landfill and Recycling Facility Waste Management Renewal Energy Plant
Only available until 2PM on 6 October
The facility takes landfill gas from decomposition of waste and uses to fuel eight (8) Reciprocating engines to produce electricity
