Fan retrofits by ebm‑papst
By 2030, the Singapore government aims to reduce energy consumption in buildings and green 80% of all new and existing building stock. To achieve this goal in existing buildings, retrofitting is always the more sustainable option than tearing it down.
Air Conditioning and Mechanical Ventilation (ACMV) systems can account for more than 60% of the energy consumption of a building. Of that value, fans can account for 35% of the energy consumption.
Therefore, implementing energy-efficient fan technologies can be one of the strategies building owners and facility managers deploy to reduce their energy consumption.
EC stands for ‘Electronically Commutated’, which means it is a fan with a Permanent Magnet Motor (PMM). EC motors are more efficient than AC motors because they use permanent magnets rather than inducing a secondary magnetic field in the rotor. ebm‑papst has pioneered the development of EC motors and fans, which can be connected directly to an AC mains supply rather than a separate DC power supply, making them easy to retrofit as a replacement for inefficient AC fans.
