Calculate tonnage of heating and cooling equipment needed based on square footage of homes, such as 1 ton for every 1,000 square feet. Find the overall tonnage by factoring several criteria such as number of windows, people in the house, thermal properties of appliances and overall heat gain of the dwelling.Know More
Know the general rule of thumb for newer homes in the United States, which is 1 ton of equipment for every 1,000 square feet of living space. Realize that energy-efficient homes may only need 1 ton for every 2,000 square feet.
Calculate variables that add heat to a home. A human body averages 230 BTUs per hour. The total amount of appliances account for 1,600 BTUs in an hour, and lighting adds another 1,600 BTUH. Houses with more efficient appliances, fewer windows and better lighting do not have as much inside heat. Denote that heating and cooling zones mean different needs based on local climates. Square footage needs for HVAC equipment differs from warmer climates to cooler climates in the United States.
Get assistance from computer programs that help by automating the process. Find programs that follow the "Manual J" method adopted by the Air Conditioning Contractors of America. When calculations are done correctly, the computer program determines a smaller air conditioner is needed than what is normally calculated using a rule of thumb.
To figure out the size of air conditioner that is needed for a space, the square footage needs to be established so that the cooling capacity can be determined. It is important that the air conditioner is not too small or too large for an area as either of these can waste energy.Full Answer >
The pricing of a modular home is set by the individual company, but, in general, it is possible to take a base square footage price and apply multipliers and additional fees to this value, according to Modular Home Owners. This base square footage price does not include shipping or customizations.Full Answer >
To estimate an interior paint job, one must consider the cost of paint, the square footage to be covered, other painting supplies needed, the labor costs if one is hiring painters and any special needs of the specific job. With this information in hand, one can calculate the costs of the job or use a job cost estimator to produce a final estimate.Full Answer >
Determine the square footage to be covered with insulation by measuring the height and width of the surface and multiplying those numbers. An 8-foot by 10-foot wall would be 80 square feet and would require two rolls of insulation at 40 square feet each.Full Answer >
