HOW BIG ASS FANS IMPROVE ENERGY EFFICIENCY
DID YOU KNOW?
Approximately 40% of energy consumed by buildings is used for heating and cooling to achieve thermal comfort. This rate can be reduced significantly through climate responsive design that integrates High Volume, Low Speed (HVLS) fans into a building’s HVAC system. Air conditioning on its own can be extremely expensive to install and run. Big Ass Fans’ products work with air conditioning systems, with fans using a fraction of an HVAC system, thereby reducing overall energy consumption. The use of ceiling-mounted fans to provide air movement for cooling in industrial and commercial premises is particularly essential in warm, humid climates like Australia. According to researchers in the US, using large diameter fans in place of conventional fans contributes to energy savings of 40%. ix
By incorporating Big Ass Fans into building automation systems, energy savings become easy and automatic. ASHRAE Standard 55 is an American National Standard that establishes the ranges of indoor environmental conditions to achieve acceptable thermal comfort for occupants of buildings. It defines six important factors that determine overall thermal comfort, including air speed, air temperature, radiant temperature, humidity, clothing insulation and metabolic rate. To comply with ASHRAE Standard 55, less than 10% of occupants should be dissatisfied with the comfort level. Big Ass Fans makes occupants feel cooler, allowing the thermostat setpoints to be raised without sacrificing comfort. Every setpoint raised can save 3–6% in energy costs. x
Australia’s National Climate Resilience and Adaptation Strategy explains how building resilience to the physical impacts of climate change and extreme weather events is vital for the long-term sustainable growth of a business. In 2015, the Australian Government agreed on a target to reduce national emissions to 26–28% below 2005 levels by 2030. The government is in the process of implementing initiatives to achieve low-cost emissions reductions, including improving the use of low- energy reliant technology and developing a low emissions technology roadmap. viii
