TDE provided MEP services to deliver a naturally ventilated high-end residence complete with radiant floors. The building is located on Pacific Avenue on a narrow lot but climbs to four stories with panoramic views of San Francisco bay.

The house construction is a wood frame building with the basement comprised of concrete and steel. The façade is modern in nature with large windows, aged copper and wood paneling. The roof sports a Jacuzzi, a full wet bar and built-in cooking area for entertainment.

Each room has a dedicated heating zone with 14 zones throughout the house. A central stairwell that acts as a light well and a thermal tower. TDE took advantage of the openness of the design to encourage natural ventilation via operable windows on the north and south faces of the building with a main entry low-level air intake louver and a top of light-well ventilation/exhaust louver. To assist the ventilation process a roof mounted exhaust fan was installed and connected to one of the main stairwell, roof access louvers.
Radiant heating with a dedicated zone control system ensure thermal comfort in all areas of the house and on all floor finishes. Combined together, the natural/forced ventilation system and the radiant floor system offer an energy efficient and cost effective solution to residential thermal comfort.
