A Winter Guide to Air Conditioning and Ventilation

30th May 2022

The nights have drawn in, the mornings are darker, and the annual flu season is upon us. This year, we are faced with the double threat of flu and Covid-19 in the workplace.

This article aims to illustrate some of the industry best practices when it comes to using and managing your ventilation and comfort cooling AC this winter.

During the early stages of the pandemic, air conditioning received bad press as being a contributory factor in the spread of COVID-19 inside buildings. Indeed, a poorly designed, poorly maintained HVAC system with no filtration and no supply of fresh air has the potential to recirculate virus-laden air. However, an appropriate HVAC solution with suitable supply/ extract provision coupled with ventilation, would have the adequate rates of air changes to be safe. In fact studies show doubling ventilation in a space can reduce the risk of transmission of the COVID virus by half. Since ventilation is such a crucial determinant of overall Indoor Air Quality (IAQ), it is vital that ventilation, in all settings, is given the attention needed.

DOs and DON’Ts

Here are our selection of DOs and DON’Ts this winter…

  • DO consider using means of natural ventilation where appropriate. Opening doors and windows is a free way of getting fresh air into the building. However, do always consider the outdoor pollutants and their effect on your building’s IAQ when considering this option.
  • DO pay attention to the positioning of your HVAC units ensuring there are adequate rates of air change in all parts of your building. Incorrect positioning of units can disrupt the flow and lead to recirculation of stagnant air.
  • DO ensure all mechanical equipment is maintained frequently by a competent engineer, as per the manufacturers’ guidelines. This will ensure the filtration stays effective and the systems run at their best.
  • DON’T just think because your building has air conditioning, that it will provide adequate amounts of fresh air. Ventilation is paramount.
  • DON’T crank your air conditioner up to the highest temperature to kick out more heat. The unit will not emit the warm air any warmer or any faster, and this will just consume more energy.
