How Can We Conserve Energy in Buildings


Energy conservation will reduce operating costs in buildings. It’s especially the case in buildings with spaces of high usage such as offices, restaurants, schools and healthcare facilities.

How can we conserve energy in buildings

To conserve energy and reduce operating costs, one way is to upgrade, replace or simply service the building HVAC system. After all, HVAC takes up to 50 per cent of a building’s monthly energy use. The percentage could go even higher on unusually hot or cold days where heating and cooling equipment must work harder and consume more energy.

Although reducing or minimising HVAC use is always an option, building tenants and other occupants still need to stay productive and accomplish things (including shopping and dining out). A comfortable temperature level should be maintained throughout the day or night. As a result, HVAC systems still need to run despite the high energy usage associated with them.

Fortunately, there are modern ways to make HVAC systems save on energy. It can start with improving the ventilation and insulation of the building (including adding high-performance window glazing and external window shading). About the HVAC systems themselves, some perform a ‘night purge’ wherein the building is flushed with natural cool air at night (instead of solely relying on mechanical cooling). Proper maintenance and prompt mechanical repairs can also help HVAC systems save on energy.

Other pratical ways for optimising HVAC systems are about detecting and fixing duct leakage, forecasting and responding to heating and cooling demand and setting automatic controls according to building occupancy. Often, all these measures are done in a structured and comprehensive manner for maximum energy efficiency.

Towards having a low-energy building

The recent trends are always about driving down energy consumption because of rising energy prices and increasing pressure on our environment. As a result, more and more buildings now have lower energy footprint especially when it comes to their heating, ventilation and air conditioning systems.

Aside from lower energy consumption and lower operating costs, other benefits also include gaining a higher return on rentals and increased property value. After all, prospective investors and buyers now prefer buildings and properties with lower energy consumption.
