Commercial Heating Systems Example

More than 100%

You create a valuation for a building that has a heat pump for typical heating but also has electric baseboard heat for supplemental heating on days in which the pump cannot generate enough heat. In this case, you could enter 100% heat pump and 10% electric baseboard or wall unit for a total of 110%.

Less than 100%

You create a valuation for a building such as a warehouse in which 75% of the gross floor area is heated with electric baseboards and the other 25% is unheated. In this case, you would enter 75% electric baseboard or wall unit and 25% ventilation only.
