We offer a range of tailored services to help you meet today’s growing energy demands:
BLOWER DOOR TESTING
Our certified blower door testing identifies air leaks and envelope inefficiencies, ensuring your buildings meet air-tightness standards required by code compliance, ENERGY STAR, and LEED for your business or home.
ENERGY EFFICIENCY CONSULTING
We work with developers, architects, and builders to integrate energy-efficient design strategies from the ground up, improving building envelope performance, reducing utility costs, and increasing occupant comfort.
WEATHERIZATION
We help you reduce heat loss and improve indoor air quality with insulation upgrades, air sealing, and moisture control solutions. These enhancements lower heating and cooling loads and extend the life of your building systems.
We pride ourselves on being a reliable, technical partner who understands both the construction site and the sustainability blueprint. Let B5 become your energy efficiency and weatherization expert in Chicago and the surrounding areas.
