New construction in Washington State requires builders to hit some energy efficiency marks, or as the code state credits. The number of credits you will need to achieve will be based on the size of the home. Here are the credits required based on size for 2015 IRC-1. Small Dwelling Unit: 1.5 credits Dwelling units less than 1500 square feet in conditioned floor area with less than 300 square feet of fenestration area. Additions to existing building greater than 500 square feet of heated floor area but less than 1500 square feet.

Scientific Basics of an Insulator- Wenatchee and Chelan Home Inspections The basic principle of any insulator is its ability to limit the transfer of heat energy. Heat is the energy exchange between two thermodynamic systems which differ in temperature. Like the Sun to the earth or your bare body to snow. The transfer of thermal energy will always go from the system of higher temperature to the colder system. When the two systems have reached a thermodynamic equilibrium (same temperature) they will cease to exchange thermal energy.
Heat moves by three basic ways: conduction, convection, and radiation. The first … (4 comments)
Chelan and Douglas County Home inspections-The need of Proper ventialtion Proper Attic Ventilation

It is generally required that one square foot of free vent area be provided for every one hundred and fifty square feet of ceiling area. Proper ventilation will help to keep the home and garage cooler during warm weather and extend the life of the roofing materials. Proper ventilation will also help reduce the potential for heat build-up and condensation within the attic. One of the critical aspects of … (0 comments)
