ERV handles the airflow for the Proud Green Home at Serenbe

One of the challenges in building an energy-efficient home is planning for adequate ventilation in a tightly sealed structure.

For the Proud Green Home at Serenbe, architect Chris Laumer-Giddens and builder Luis Imery took into account the super tight building envelope that's a result of the Huber ZIP System R Sheathing and Tape, and the Home Slicker ventilating rainscreen from Benjamin Obdyke. Spray foam insulation from BASF also contributes to the tight envelope.

Take a virtual tour of the Proud Green Home at Serenbe.

The Proud Green Home is being built southwest of Atlanta in the sustainable community of Serenbe. It has will be certified EarthCraft House Platinum, ENERGY STAR Version 3.0, EPA Water Sense, and EPA Indoor Air Plus. The home will also produce on-site electricity (photovoltaics), and will be a net-zero home, in other words it will produce as much energy as it uses.

The home was designed to keep the energy consumption to 55 percent less than that of the same home built to meet the current energy code.

To ensure the home has the proper amount of air change to control moisture and provide a high level of comfort, the home is using an energy-recovery ventilator (ERV) from Zehnder America to supply fresh air.

An ERV provides a flow of fresh air to the home, and exhausts stale air. During that process, it allows some of the moisture in the more humid air stream (usually the stale air in winter and the fresh air in summer) to be transferred to the air stream, which is dryer.

The Zehnder ERV is a full-ducted ventilation sytem that will provide fresh air to the bedroom and exhaust air from the bathrooms and kitchen.

"It will provide the optimum ventilation and fresh air with the lowest amount of air movement possible to provide the air change," Imery said. "It's the Porsche of ventilation systems."

In partnership with Southface Energy Institute, will monitor the performance of the home after it is completed and occupied in order to provide real-life feedback.

The home is designed to achieve performance ratings in multiple programs including Earth Craft House (Platinum Level), ENERGY STAR (Version 3.0), EPA WaterSense and EPA Indoor Air Plus. These certifications give the owner the assurance that their home is designed and built to the highest standards in home energy efficiency, durability and sustainability.

LG Squared, Inc.’s unique house-as-a-system design approach results in a beautiful home with a high performance building shell and integrated high-efficiency HVAC system. As part of this collaboration, their expert application of cutting edge products has been made possible by the generous contributions and sponsorship from industry leading brands such as Huber Engineered Woods (ZIP System), Benjamin Obdyke, BASF, LG, Zehnder America, Boral Brick, Metal Sales, PlyGem, KOHLER, and KleenWrap.
