As of January 2011, this is believed to be the highest scoring LEED Platinum home in the state of Florida with 112 points.  Located at 4512 Grove Park in Tallahassee, the craftsman bungalow style home is owned by Mark and Linda Powell and features two-level living, SIPs construction, a large solar PV array, and EPA Indoor airPLUS certification.

The home is 3,000 square feet and earned a HERS index of 18 — i.e., it’s about 82% more efficient than a standard code-built home (a net-zero home would receive a HERS index of 0).  The home has Bosch appliances, Energy Star televisions, a GreenSmart Fireplace Extrordinair, SIP wall and roof panels, and a WaterFurnace geothermal heat pump.

To capture renewable energy from the sun, the home has a 5.2 kW Sharp photovoltaic system and a 50-gallon Progressive Tube solar hot water system with an 80-gallon conventional tank and recirculation loop.

For water savings, the home in Southwood has WaterSense fixtures, native landscaping, micro irrigation, pervious concrete and walks, rainwater harvesting, and a rain garden.

Other green products include sustainably harvested heart pine floors (Red Hills Lumber), fiber cement shake siding (Nichiha), low-VOC paints (ProMar), wheatboard kitchen and bath cabinets (Koch), interior doors (CraftMaster), and an FSC certified entry door (MAI).  Lastly, the air is maintained with an ERV and HEPA/MERV 13 filters.

All in all, this home demonstrates sensible traditional style, a balanced and impressive green approach, and the collaboration of several members of a project team including architect Kevin Sossong, builder Jake Myddleton, landscape designer David Copps, and interior designers Leilani Aletras and Barry Pujals.
