This translates to substantial savings over the lifespan of the siding.
The reduction in energy consumption achieved through insulated siding is directly related to several key factors. These include the climate in which the house is located (colder climates see greater heating savings, while hotter climates see greater cooling savings), the size of the house (larger houses naturally require more energy), and the level of existing insulation in the walls and attic (better pre-existing insulation means less impact from the siding, but still offers benefits). The type of insulated siding chosen also plays a crucial role, with different materials offering varying levels of R-value (a measure of thermal resistance).
Energy Savings Calculations
Calculating potential energy savings with insulated siding involves a multi-step process. While precise calculations require professional energy audits and specific software, a simplified estimation can be made using readily available information. This estimation will provide a general idea of the potential benefits.
- Determine your current energy consumption: Check your utility bills to find your average annual energy usage for heating and cooling. Let’s assume, for example, an annual energy cost of $1500 for heating and cooling.
- Estimate the R-value improvement: The R-value of standard siding is typically low (around R-4 or less). Insulated siding can significantly increase this, with values ranging from R-5 to R-15 or higher, depending on the material and thickness. Let’s assume an improvement of R-10.
- Consider your climate: A colder climate will yield higher savings on heating, while a warmer climate will result in greater savings on cooling. The percentage of savings will depend on this. Let’s assume a moderate climate resulting in a 15% reduction in energy usage.
- Calculate potential savings: Multiply your current annual energy cost by the percentage reduction. In our example: $1500 x 0.15 = $225. This represents the estimated annual savings.
Illustrative Scenario: A Case Study
Consider a two-story house in a moderate climate with 2000 square feet of exterior wall space. Currently, it uses $1800 annually for heating and cooling. Installing insulated siding with an R-value of 12 might reduce energy usage by approximately 20%. This translates to potential annual savings of $360 ($1800 x 0.20). This is a simplified example and actual savings may vary depending on factors such as window efficiency, overall home insulation, and individual energy usage patterns. A professional energy audit would provide a more precise estimate.
Potential savings = (Current annual energy cost) x (Percentage reduction in energy usage)
