06 Sustainability
Air hygiene is an energy measure.
Fouled systems work harder to move the same air. Scroll the drawing — cleaning drops the gauge.
06.1 The NADCA energy result
Scroll: fouling comes off, the energy gauge comes down.
Fan and blower energy fell 41–60% after fouled air handling systems were cleaned — NADCA energy research project. Drag to rotate; scroll to run the clean.

Results depend on how fouled the system is — which is why every engagement starts with an inspection that measures yours. We publish only system-level, sourced numbers; anything unverifiable doesn't ship.
What we do on-site
- HEPA-filtered containment — captured contamination stays captured
- Responsible disposal of removed debris and filter media
- Chemical-minimal methods: mechanical source removal first, agents only where indicated
- Post-service energy talking points your team can lift into the ESG report
Feeding LEED, WELL & ESG reporting
What your frameworks want is data, and cleaning produces it: pre/post airflow readings, photographic evidence of restored components, and a dated report. That supports IAQ and ventilation-effectiveness intents in LEED and WELL, and gives corporate ESG reporting a measured operational-efficiency line item.
On the projects side, rain water harvesting installations serve the same reporting need for water stewardship.
Energy & reporting questions
How does duct cleaning reduce energy consumption?
Dust on coils and duct surfaces forces fans and compressors to work harder to move and condition the same air. Removing the fouling restores design efficiency — NADCA’s energy research project measured 41–60% lower fan and blower energy consumption after cleaning fouled air handling systems.
Can HVAC cleaning contribute to LEED or WELL credits?
Cleaning itself is not a credit, but it supports the IAQ performance, ventilation effectiveness and energy-optimization intents both frameworks score. The post-service report — airflow readings and photo evidence — is documentation your consultant can cite.
What data do we get for ESG reporting?
Every project closes with before/after photos and, where scoped, airflow readings against the pre-clean baseline. That gives your EHS or sustainability team a dated, sourced data point — a measured operational improvement, not an estimate.
