Three townhouses at 3011, 3013 and 3015 Cohoon Street recently completed in O’Bryonville earned LEED for Homes certificaton. LEED (Leadership in Energy & Environmental Design) is a green building certification program that recognizes best-in-class building practices for energy efficiency, sustainability and occupant health. To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. This project earned Gold certification on 11/25/15. These homes replaced two 1900’s bungalows and were designed with an “Italianate” exterior to fit with the predominant style of the neighborhood. The interiors are a modern open floor design, featuring high ceilings, hardwood floors and master suite with a large walk-in closet.
The project was developed by Renee Duncan LLC, a new company focused on energy efficient new construction and renovation. The builder was Potterhill Homes Ltd., a leader in the area for energy efficient construction techniques and LEED certified homes. For more information on “The Potterhill Difference” you can visit their website at www.potterhillhomes.com. This project’s building envelope consists of 2×6 exterior walls vs. standard 2×4, increasing the amount of insulation. Attic insulation is also 30% more than standard. Special attention was placed on air sealing the envelope to reduce infiltration of hot air in the summer and loss of warm air in the winter. The average HERS index (Home Energy Rating System) for the three homes was 58 vs. 100 for standard new construction and 130 for typical older resale. This translates into real energy savings for the homeowner.
Renee Duncan LLC was formed by two recently retired Procter & Gamble women managers. As the two began working with various vendors on this project, one question always arose. Who is Renee Duncan and when do we meet her? Actually, the name of the company consists of the owners’ middle names so Renee Duncan is not an actual person – even though they both wish she would pay the bills. With this project completed, sold and occupied, they are now looking for their next green building or renovation opportunity.
