Manual N Load Calculation
Why a Manual N for Commercial Load Calculations?
The Manual N for commercial load calculation is designed to instruct contractors and others on how to meet the complicated new heating and air conditioning requirements for commercial buildings. This manual treats in detail all that you will need to know, including the latest developments in the commercial construction industry such as the use of new materials, assembly, operational requirements, and more. Being up to date on your commercial load calculation will ensure that you meet any possible building codes that may be in place, are keeping the occupants safe and comfortable, and are keeping the utility bills as low as possible.
Commercial Load Calculation
As will eventually happen, when it comes time to replace your heating and air conditioning system in your commercial building, be sure to have a professional technician perform a commercial load calculation beforehand. A ‘load’ is the amount of heating or cooling that is required in order to maintain the temperature level comfortable enough for the occupants. A ‘commercial load calculation’ is the complicated process by which you come to determine the exact size of the load and the size and power of the heating and cooling system that will be needed. Choosing the correct size of the system will be important for several reasons, as mentioned quickly above.
In general, if the size of your heating and cooling system is too small and too weak, it will, of course, not be able to properly affect the temperature of the rooms, resulting in an uneven spread of temperature regulation. Also, if they are too small, they will be working overtime in an attempt to regulate the temperature, which will result in the units breaking down prematurely. On the other hand, if the cooling and heating units are too big, too powerful, they will be producing too much heating and cooling, even when set to their lowest setting. This will result in indoors being too hot or too cold, and it will also result in accumulated amounts of humidity.
Having the perfect sized heating and cooling system unit for your commercial building is key, and using a commercial load calculation will help achieve just that. This calculation will be determined by inserting the physical and thermal characteristics of your building.
- Size of the building
- Number of doors and windows
- The efficiency of the sealing
- Expected climate.
