Environmental sustainability is becoming more and more important in building design, construction and maintenance. In a commercial building the majority of the energy consumption comes from the lighting (39%). 28% is used for HVAC and 33% for office equipment, computers and refrigeration (US Energy Information Administration).
Reducing energy consumption is a key objective for many building managers. With some key enhancements in lighting technology in recent years, there are some simple ways to achieve reduced energy consumption in your premises.
Replacing your existing lighting with LEDs can reduce electricity bills by up to 50%. One of the main reasons for this is that the majority of the energy consumption used by an LED light goes into producing light, whereas with traditional incandescent lamps almost 90% of the energy is lost in the form of heat.
LED lighting also has a big impact on a buildings EPC rating (Energy Performance Certificate). If you haven’t already considered this, you should. In 2018 new legislation will come into force stipulating that any let commercial building must have an EPC rating of A-E.
Installing light sensors can also have a significant impact on the energy consumption. Especially in rooms that are not continuously being used, such as meeting rooms, toilets and kitchen areas. Intelligent sensor technology now allows for the brightness of lighting to be altered depending on how much daylight is detected in the room.
Sensors can be used for more than just the lighting. Heating and air conditioning can also be controlled by sensors, meaning that you won’t be wasting energy heating a room that is not occupied. You may also want to review your timing controls for heating and lighting, ensuring that the minimal amount of energy is being used when the building is not in use.
