From Pilot to Campus-Wide: IAQ at Christian Alliance School

Christian Alliance International School's brand-new Lai Chi Kok campus looked great — and smelled terrible. Fresh paint, new furniture, and construction materials filled the classrooms with harmful VOCs. With the academic term fast approaching and young children about to walk through the doors, the school needed a solution that worked fast and worked reliably. There was no room for trial and error.

RHT started with a pilot: eight EC 920 ceiling-mount NCCO units. Independent testing confirmed IAQ hit the EPD's 'Excellent' benchmark within days. The school's response said it all — they ordered 73 more units on the spot, bringing the total to 81 covering every classroom and common area. When the proof of concept is that compelling, scaling is the easy part.
