When Andy and Cathy Homoly built their new Parkville home in 2012, they wanted the highest level of energy efficiency — with no energy bills — in a traditional, southern-style house. Their 4,200-square-foot home is certified Leadership in Energy & Environmental Design (LEED) at the platinum level. The LEED for Homes program of the U.S. Green Building Council awards certification for houses that meet the highest levels of sustainability for energy and water efficiency, materials and resource management, indoor air quality, sustainable sites and other criteria. The Homoly home features a 25kW ground-mounted solar array, solar-powered heat pump, energy recovery ventilator, 1.5 kW wind turbine, micro-hydroelectric generator from pond to lower creek, R30 wall insulation and R45 roof insulation. A 1,500-gallon cistern captures rainwater for flushing toilets. Homoly Construction built the house and Homoly Solar installed the renewable energy features.
The Homoly house is open for tours at 11:30 a.m. and 1:30 p.m. at 6401 NW Monticello Drive in Parkville, MO.

Creating an air barrier at the sheathing level and insulating on the exterior with rigid foam insulation is key to the PERSIST and REMOTE building strategies as well as Andrew Homoly’s “perfect” building envelope.
Is there such a thing as a perfect building envelope? One that could be mass-produced from readily available materials, and be appropriate for 90% of all new homes?
Andrew Homoly thinks he’s found one, as he explains in this Q&A post at GreenBuildingAdvisor.
Here are the basic elements:
It is this last detail, the insulated and vented soffit and fascia, that has Homoly thinking he’s nailed it. He calls his approach the Homoly-Pedley Perfect Envelope, sharing the credit with his framer, Mike Pedley, who came up with the soffit/fascia detai
“Note the ‘gap’ goes all the way up the wall, around the soffit, around the facia, and up the roof to the ridge vent,” Homoly writes. “Periodic vent strips could also be added in the soffit if desired. The entire home from foundation to wall to soffit to facia to roof is wrapped in an uninterrupted thermal envelope.
“I believe this system accomplishes multiple goals … and could easily be mass-produced since it utilizes all common building techniques and materials.
After you answer, ask yourself “Why?”. After you answer this, keep asking why until you get to what you know is your final answer. For most people, it will go like this… “My biggest goal is to start my own company… or meet my future spouse… or start an exercise program…” When they answer the why question, it will sound like this… “So I can have more freedom… or to start a family… or to be healthier”.

The home’s power consumption is monitored by eMonitor, a device installed in the circuit box which provides real-time consumption data of all electricity usage throughout the home on a circuit-by-circuit basis and tracks energy production by the renewable and/or alternative sources on the property.

The Homoly Residence epitomizes green building. Spearheading the Kansas/Missouri high-performance building movement, owners Andrew and Catherine Homoly have incorporated the height of technological advancement and responsible building in their personal home.
The architecture, layout and overall vision of this home represents years of planning and dreaming on the part of its owners. Andy hopes that this traditionally-styled home will help prove to skeptics that energy efficient, high-performance structures do not have to look modern or modular as some assume, nor does this style of building have to break the bank. Technology and construction materials have advanced to meet the demands of even the most traditional styles. Home Tours are available upon request. Continue reading
The Heartland Renewable Energy Society’s 13th Annual Tour
Don’t miss the 2012 Energy Solutions Homes Tour on October 6, 9:00 am – 4:30 pm. The Homes Tour will feature 8 locations touting energy efficiency and renewable energy in virtually every part of the KC Metro area. The Tour will be a “self-guided” tour, meaning that attendees will select the homes they wish to see and the times they wish to see them, and then drive themselves to the homes of most interest to them. $10 tickets for the entire Tour will be available at any of the Tour Homes (kids 12 and under are free. Visit four of more sites and receive a $10 gift certificate.). Greenability Magazine will feature the Homes Tour in its September-October issue. You can find Tour Homes’ addresses there or at the Tour website www.kcsolar.org. The website has photos, directions, home features, and an interactive map of the tour sites. Continue reading
Another new solar installation is happening at the Randy Reed Buick GMC. Solar and Wind KC is installing a 100.32kW system, with American-made panels manufactured, assembled and supplied by an American company. These panels offer state of the art technology because the panels receive bi-directional light via a reflector panel that is mounted on the adjacent side of each solar panel. The addition of the reflector panel increases output by more than 30%! The Randy Reed array covers approximately 16,000 square feet of space and is mounted over a water detention area, a space previously wasted on the property where square footage literally means dollars for a car dealership. This solar array is estimated to harvest 182,000 kWh of electricity per year, and an estimated $18,500 in first year savings.
Solar and Wind KC has unveiled a unique combination of rooftop solar panels and solar awnings at the Parkville Heights Animal Hospital. The roof-mounted array maximizes energy capture, while the solar awnings provide instant usable power via micro-inverters as well as shade. This approach utilizes an advance in solar technology called micro-inverters which allows for separating and mounting panels around the perimeter of a site, instead of all panels being mounted together as with traditional systems and inverters. Now, the solar awnings are an incorporated piece of the building’s architecture. The solar array also is equipped with a special type of inverter, which not only changes direct current to alternate current but also actively monitors the solar array and adjusts for periodical shading. The overall solar array is a 25kW system, and the awning structure was designed exclusively by Solar and Wind KC.
The Williams-York Residence in Leawood, KS has recently been certified LEED Platinum, the highest certification level from LEED for Homes by the U.S. Green Building Council (USGBC) and the Green Building Certification Institute (GBCI).
