Every minute of every day, valuable data is collected about energy consumption at the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) headquarters in Atlanta. This data is accessible to researchers around the world, allowing them to monitor performance of the building’s resource-conserving systems and extract data for further study.
ASHRAE, the international oversight organization for the heating, ventilation, and air conditioning (HVAC) industry, completed a $6.2 million renovation of its 30,000-square-foot headquarters in 2008, creating a sustainability showcase to promote renewable energy, water efficiency, indoor and outdoor environmental quality and, above all, highlight the energy efficiency of …show more content…

VRF manufacturer Daikin disputes the findings reported by HIA. ASHRAE isn’t formally endorsing one technology over the other, though the data is available online for review by industry professionals.
While there is growing interest among consulting engineers, contractors and building owners to adopt new HVAC technologies such as VRF, a lack of performance data should temper acceptance of manufacturer efficiency claims. The concern over sparse data has been noted in a number ofpapers on VRF, including this 2012 report prepared by the Pacific Northwest National Laboratory for the U.S. General Services Administration: “Surprisingly, despite the long history with VRF technology in Europe, Japan and elsewhere, the U.S. research community has not found useful research on VRF from these places. While some general literature is available about these systems, there is a lack of critical evaluation of actual field energy performance.”
In addition to strong mixed views on efficiency, a number of perceptions exist among industry professionals on the advantages and disadvantages of VRF systems, driven in large part by aggressive marketing and education campaigns by VRF manufacturers.
Key areas of differentiation between the two types of HVAC systems are outlined as follows, along with important considerations for those who influence system selections.
