For commercial buildings, the building envelope (walls, roof, windows, doors, and insulation separating indoors from outdoors) is one of the most important yet overlooked opportunities to reduce energy waste and improve comfort. When the envelope leaks, a building’s heating and cooling systems work overtime, driving up utility costs and creating drafty, inconsistent indoor temperatures.
Why Weatherization Matters
Lower Energy Usage and Operating Costs
Air leaks, damaged insulation and thermal bridging are major drivers of unnecessary heating and cooling loads.
A More Comfortable, Productive Indoor Environment
Drafts, temperature fluctuations, humidity problems, dust and noise can all stem from a leaky building envelope. Weatherization helps stabilize indoor temperatures and humidity levels. The result:
- More comfortable conditions for employees and customers
- Increased staff productivity
- Improved indoor air quality
Lower Maintenance Risk and Longer System Life
Poorly sealed buildings force HVAC systems to run longer and harder. Keeping conditioned air in and unconditioned air out reduces equipment runtime, prevents moisture damage and protects a building’s infrastructure.
Real CO2 Reductions
Envelope upgrades directly cut fuel usage. By reducing air leakage, buildings lower natural gas consumption and their overall emissions.
