BUILDING MECHANICAL SYSTEMS

Title	HVAC SYSTEM
Location	Private Residence, Lorton, Virginia
Description	Performed load calculations, zone selection, ductwork design and construction consultation for the HVAC system built as part of a home renovation and addition project. System was a two-zone forced-air type utilizing a geo-exchanger.
Construction Cost	$20,000
Title	HVAC SYSTEM
Location	Private Residence, Staunton, Virginia
Description	Project to install a geo-exchange heat pump system for space heating and cooling for a new 3800 square foot home. Primary heating was provided by radiant floor panels, with forced air as a backup (and for cooling). We provided a construction specification, selected the zones, specified the heat recovery ventilator, and sized the HVAC system and backup generator. Corish Engineering also provided construction observation and commissioning services.
Construction Cost	$100,000
Title	YOGA STUDIO HVAC SYSTEM
Location	Private Residence, Boyce, Virginia
Description	Project to install a geo-exchange heat pump system for space heating and cooling and domestic hot water heating for a new yoga studio. We engineered the HVAC system and the domestic hot water portion of the plumbing system, and provided construction observation and commissioning services. The studio was built adjacent to an existing residence. The geo-exchange loop was sized to heat and cool the existing structure as well. A custom-designed fresh air system with heat recovery ventilator was also provided. This was the first LEED Gold-certified residential project in Virginia. The project received an award from the Northern Virginia chapter of the American Institute of Architects. Additional information on the project can be found at GreenBuildingAdvisor.com.

Title	BOILER REPLACEMENT
Location	Office/Apartment Building, Front Royal, Virginia
Description	Project to replace the oil-fired space heating boiler for a 6800 square foot office/apartment building. The boiler, which supplies a hot water radiator system, was aging and oversized. The client wanted to replace it with a modern efficient unit, "right-sized" for the building load. We performed heating load calculations to select the new boiler. Also recommended addition of wall insulation in one room, reducing energy use and improving temperature control by balancing envelope U-factor amongst rooms.
