5 Energy-Efficient Commercial/Industrial Roofing Strategies
When it’s time for your next roofing project, consider the impact that this assembly can have on the facility’s energy expense. Keep the following in mind.
- How your facility and its roof function impact which energy-efficient roof options are most practical.
- Evaluate where and how your facility is consuming energy. Your roof system can impact the amount of energy required for heating, cooling, ventilation, and lighting.
- Consider corporate sustainability goals and energy-efficient initiatives. A roofing project can contribute to their achievement.
Strategy No. 1: Increase roof R-value.
Insulation is the most widely understood energy-efficient roofing strategy. Refer to the International Energy Conservation Code (IECC 2012), as well as other application building codes/requirements of Authorities Having Jurisdiction (AHJs).
Strategy No. 2: Reduce thermal discontinuities.
Insulation application strategies can greatly reduce gaps and voids and increase energy efficiency.
Strategy No. 3: Install a climate-appropriate roof surface.
Identify the ideal solar reflectance and thermal emittance for the climate in your geographic location. Select a roof system accordingly.
Strategy No. 4: Restrict air movement and thermal transfer.
An air barrier is a material installed to impede or restrict the passage of air through a roof assembly. If chosen, it needs to be part of a complete building envelope evaluation.
Strategy No. 5: Install daylighting skylights.
Depending on space function, daylighting skylights can be a practical approach to reduce the need for artificial lighting and energy consumption.
