VENTILATION SERVICES FOR MULTIFAMILY BUILDINGS
Fresh air promotes well-being and a healthy lifestyle. Poor indoor air quality can lead to a rise in asthma and allergic symptoms in tenants. In a properly sealed multifamily building, controlled mechanical ventilation ensures fresh air reaches occupants without sacrificing the energy performance you worked to achieve.
SEAL TIGHT, VENTILATE RIGHT
In multifamily buildings, ventilation design must account for individual unit needs as well as common area requirements. Bathroom exhaust fans, kitchen range hoods, and fresh air intakes must be balanced to avoid creating pressure imbalances that cause doors to be difficult to open, back-drafting of combustion appliances, or excessive infiltration through unintended gaps. Building Energy Experts assesses your building's existing ventilation as part of our comprehensive energy assessment and recommends improvements that maintain indoor air quality while preserving energy performance.
— WHY VENTILATION MATTERSThe building science principle "build tight, ventilate right" exists for a reason. Air sealing and insulation dramatically reduce uncontrolled air infiltration, which is what you want for energy efficiency. But occupants need fresh air. The answer is not to leave the building leaky. The answer is to provide controlled, measured fresh air mechanically.
What We Seal in Multifamily Buildings
✓ ASHRAE 62.2 compliant ventilation design
✓ Balanced pressurization, no back-drafting risk
✓ Heat recovery for energy efficiency
✓ Filtration for allergen and pollutant control
✓ Code compliance documentation for renovation projects
✓ Compatible with all major HVAC system types
✓ Coordinated with air sealing and insulation work
— THE SCOPEVentilation Improvements We Provide
A complete ventilation upgrade in multifamily buildings is about more than installing fans. It's about designing a balanced system that supplies fresh air where occupants need it and exhausts stale air where it builds up.
Whole-Building Assessment
We evaluate existing ventilation pathways, measure current air flow rates, and identify imbalances that cause pressure problems. The starting point for any ventilation improvement is understanding what's already there.
Bathroom Exhaust Upgrade
Most multifamily bathroom fans are undersized, poorly ducted, or fail to vent outside. Proper bath fan upgrades remove moisture and odors at the source, reducing mold risk and tenant complaints.
Fresh Air Intake Design
Tight buildings need a planned fresh air pathway. We design intakes that bring in measured outside air through filters, ducted to high-occupancy spaces where it's needed most.
HRV & ERV Evaluation
Heat Recovery Ventilators and Energy Recovery Ventilators capture 70-90% of the heating or cooling energy in exhaust air and transfer it to incoming fresh air. The right choice for very tight multifamily buildings.
Kitchen Ventilation
Range hoods that recirculate instead of venting outside trap grease, moisture, and combustion byproducts inside the unit. We assess and recommend properly ducted exhaust solutions.
Combustion Safety
Tightening a building without checking combustion appliances can cause back-drafting of carbon monoxide. We test furnaces, water heaters, and other gas equipment for safe operation in any newly tightened building.
Healthy Buildings. Healthy Tenants.
Proper ventilation is the final piece of a complete building performance upgrade. We evaluate your current ventilation as part of every assessment and design a system that balances indoor air quality with the energy performance you worked to achieve.
Fewer Tenant Complaints
Asthma, allergies, and "stuffy air" complaints drop significantly in buildings with controlled fresh air supply.
Moisture Management
Controlled exhaust prevents bathroom and kitchen moisture from causing mold problems in wall and ceiling assemblies.
Recovery, Not Loss
HRV and ERV systems recover up to 90% of the heating or cooling energy in exhaust air, instead of throwing it away.
