Comparing Rescheck requirements for different climates and regions

Updated: Jun 7

Rescheck is a software tool developed by the U.S. Department of Energy (DOE) that is used to verify energy code compliance for residential buildings. Its primary function is to ensure that all new construction and renovations meet the minimum requirements for energy performance, ventilation, and insulation. Rescheck requirements may vary based on different climates and regions.

Rescheck requirements for hot and humid climates

In hot and humid climates, homes require more insulation and air sealing to maintain a comfortable indoor temperature. The Rescheck software takes into account the local climate data, such as temperature, humidity, and solar radiation, when calculating the energy efficiency of a building. In addition, Rescheck requires higher R-values for wall, roof, and foundation insulation in hot climates to reduce the amount of heat that enters the home from outside.

Rescheck requirements for cold climates

In cold climates, homes require more insulation in order to retain heat and minimize heat loss. Rescheck requirements for insulation R-values are typically higher in colder regions than in warmer ones. Additionally, the software may require an increase in window U-values, which measures the amount of heat that passes through windows.

Rescheck requirements for coastal regions

Coastal regions are often prone to high winds and hurricanes. To build a home that can withstand strong winds, Rescheck requirements in these areas may include stricter wind load, thermal bridging, and insulation requirements. Windows and doors, which are more susceptible to wind damage, may also need to meet certain impact-resistance ratings.

Rescheck requirements for high altitude regions

In high altitude regions, the air is thinner, and the temperature drops faster at night. Homes in these areas require more insulation than those at lower altitudes due to the temperature fluctuations. Rescheck may require increased R-values for insulation to maintain a comfortable indoor temperature and to prevent heat loss.


Rescheck is an essential tool for ensuring energy efficiency in residential buildings. The requirements vary based on the climate and region in which the building is located. By considering local building codes, insulation, and ventilation requirements Rescheck can provide energy-efficient guidelines for construction. A comprehensive Rescheck analysis will help builders and homeowners save money on energy bills and reduce their carbon footprint. In short, building an energy efficient home not only saves money, but it also helps to reduce greenhouse gas emissions.
