A common mistake in designing homes is overlooking the energy-saving impact of properly sized and located HVAC equipment.
The Building Code requires builders to provide documents to the inspector that show the heating and cooling load of the home, the design of the duct-work, and the size of the Heating, Ventilation, and Air Conditioning equipment. A properly designed HVAC system will improve the home’s energy efficiency by creating a system that works the least to comfortably condition the home’s air. To do that, you’ll need an expert like D.R. Nelson to perform the Manual J, the Manual S, and the Manual D heat calculations. We will determine the best HVAC layout for you that meets code and saves money.
Designing an energy-efficient HVAC system, with properly sized equipment and the best duct-work layout, will not only improve the home’s comfort, but it will save money on utility bills.
- The MANUAL J calculations determine the heating and cooling load that the home design requires of the HVAC equipment. Once the load is determined, the size and design of the HVAC equipment can be calculated so that you pay for exactly what you need, and no more.
- The MANUAL S calculations determine the proper size of the HVAC equipment. This requires finding the right balance of selecting equipment strong enough to handle the load while avoiding the unnecessary cost and waste of over-sized equipment.
- The MANUAL D calculations determine the design of the HVAC duct-work. With a proper layout, the conditioned air moves directly to where it needs to go with the least amount of burden on the equipment.
