When considering the right size, application and style for your building’s HVAC system, there is a way to ensure energy efficiency as well as maximise the comfort of those inside at any given time by using a mathematical process known as ‘load calculation’. This is a more precise way of calculating efficiency and comfort; therefore, it is better than the ‘rule-of-thumb’ method which is still in use today.

Over the years, this load calculation has become faster and increasingly consistent due to advances in technology. According to engineering consultants in Dubai and engineering companies in Abu Dhabi, load calculation should take into consideration multiple factors about the structure. These include verifying the total square footage of the property, factoring in the number of floors (living space vs. attic space), windows, doors and entry ways, analysing the type/ location/ density of insulation, considering the condition/ size of the duct work and vent systems, and finally examining how much the landscaping, as well as shades, blinds or other treatments, allow/prevent sunlight from entering the property. JPW Group suggest that before hiring a contractor, you should find out if their service will include load calculation incorporating the list above.

So, why is this important? There are multiple reasons why engineering companies in UAE should make the permanent switch to load calculation. Choosing the right-sized system will ensure maximum efficiency and comfort, lowering your utility bills and ensuring fewer service calls. Your systems will consume less energy than if the system was too big, a.k.a. ‘oversizing’, since it takes more energy to run a larger system (‘short cycling’). If your systems are too small, a.k.a. ‘undersizing’, they may run continuously to meet output levels and are more likely to malfunction. Therefore, the capacity of your equipment should always match the area being heated or cooled, and it’s the load calculation that will provide you with the right information to make an informed decision and avoid oversizing or undersizing.

JPW Group suggest taking on a specialist to calculate your heating and cooling load as a much safer way of approaching this important engineering process. Load calculation can take time, and less experienced engineering companies in UAE risk miscalculating, which will result in various problems down the line. Seasoned MEP consultants in Dubai are less likely to make mistakes due to the volume of cases they have handled over the years.
