BOULDER, Colo.–(BUSINESS WIRE)–Heating, ventilation, and air conditioning (HVAC) in commercial buildings typically accounts for roughly 40% of total building energy consumption. While advancements have been made in the efficiency of HVAC equipment, the actual energy consumption of HVAC equipment depends largely on their operation – which can be made much more efficient and less energy-intensive through the application of advanced HVAC controls. […]
“The drive to reduce energy use in commercial buildings has put a spotlight on improving the efficiency of HVAC systems, and HVAC controls retrofits offer a compelling value proposition through reduced energy consumption in existing buildings.”
New building certification and benchmarking regulations are driving faster retrofits of controls in existing buildings, according to the report, and changing how automation is designed into new buildings. The wider adoption of open standards for controls functions (such as BACnet), and of communications based on the Internet Protocol (IP) suite and Ethernet connectivity, is expected to help bring advanced HVAC technology to a wider market.
Buildings in the U.S. consume[…] 42 percent of the nation’s primary energy and 72 percent of its electricity. Much of that energy is needlessly wasted through inefficient design and operation.
Duane Tilden‘s insight:
>Rather than examine energy costs in isolation, our approach assesses how energy and sustainability improvements add value to all parts of a property or company. This approach is not revolutionary, but rather more comprehensive, applying industry-accepted valuation methods to the full set of retrofit value contributions, including saved energy costs, health and productivity benefits, reputation and leadership, and risk reduction.
Energy investment (and resultant property outcomes) should be treated as one of many factors that influence value, including location, tenant mix, quality of design, and more. Evaluating retrofits within the broader context of property/company value enables a logical, defensible calculation and assessment of a deep retrofit’s relative contribution to value. Previous attempts to value energy retrofits have ignored retrofits’ value contributions and overlooked standard approaches to valuing properties and companies.<
