The size of your HVAC system is very crucial since in most cases it will affect the overall efficiency in heating and cooling. The mistake most people make is to think that just because an HVAC system is big it is good enough. A lot of modern buildings today are prioritizing energy efficiency, and right sizing the HVAC system in line with the building requirements is one way of achieving this goal.
In most cases, people will determine the size of HVAC systems needed based on outdated specs and ultimately this will lead to avoidable mistakes. Here are some simple tips that can help you get the size of your HVAC system right:
Design Buildings with HVAC in Mind
It is very important to take care of the duct and distribution right from the start. During construction, the builder should understand where and how the system will be installed and make the right layout to ensure this is achieved. The HVAC systems and ductwork should preferably be placed on the conditioned envelop of the building. The attic should only have more insulation. This approach in right-sizing will basically ensure that even the equipment size is resized accordingly.
Test the Systems Performance
After you have designed the layout of commercial HVAC system, it is also nice to test your system to see if it meets the specifications you want. In most cases, testing is as easy as gauging how effective cooling and heating is and the overall amount of energy you are using. If you can get help from an HVAC technician, testing the efficiency of the installed system can be done as fast as possible without any margins for error.
The right Window U-value and SHGC Must Be Factored
When you are determining the size you need for your HVAC system you should remember to factor the Window U-value and the Solar heat gain coefficient. Getting these two factors wrong can have a significant impact on the HVAC system you are going to buy for your commercial space.
Right-sizing your Commercial HVAC systems will help you achieve your HVAC performance goals and can significantly reduce your construction costs.
