How Can Buildings Reduce Energy Consumption?


Given the rising energy costs, it’s a must to reduce our energy consumption while still meeting our productivity and comfort requirements. However, those two goals are total opposites. It’s a huge challenge to meet those two objectives especially given our constant need for heating, ventilation and air conditioning systems (which can account for up to 40 per cent of building energy use).

Reducing energy consumption in buildings

Although there are other constants and activities that use energy such as lighting, computers and other equipment, HVAC is still the largest energy user. HVAC systems may have to run at least eight hours each day and depending on the weather, the system might have to be at the highest settings to achieve the desired level of comfort.

However, much of the HVAC energy could still be wasted. Perhaps the spaces are unoccupied and yet the heating and cooling systems are still running at full force. Although energy is being used, it’s not being employed productively as it doesn’t result in any comfort to any occupants. The solution to this is to install sensors and a smart control system. The goal is to make heating and cooling more responsive to demand (heat or cool the space depending on occupancy levels). It also helps to set an optimal schedule and algorithms to further save on energy while achieving comfort.

Aside from making the HVAC system more responsive to demand, another way to reduce energy consumption in buildings is by upgrading the heating and cooling system. There’s a significant upfront cost here but this upgrade can result in energy savings for up to 25 years. If you’re about to compute the upgrade costs and whether it will be worth it, note that energy costs will continuously rise in the coming years. In addition, with an upgraded system (this may include more accurate sizing and with more modern mechanisms such as those of reverse cycle ACs), the energy savings year after year could be up to 40 per cent.

There are several other ways of reducing energy consumption in buildings. There’s huge opportunity and potential savings in optimising the heating and cooling systems.
