Healthy and green buildings rely on good indoor environmental and air quality (IEAQ) to maintain the wellness and productivity of their occupants, notes Navigant Research. Related IEAQ technologies can provide the measurement and verification of appropriate ventilation and moisture management.

Those actually responsible for shaping the future of IAQ products have taken notice of the swelling public interest, and trends in the marketplace show products are becoming more interconnected and accessible to the average consumer.

There is quite a bit of confusion about the costs and benefits of IAQ improvement — even among building designers, engineers, managers, owners, and tenants — according to a survey by Drexel University researchers.

Guesswork often leads to customer complaints, poor system performance, and frustrating callbacks that can be avoided with a little bit of upfront planning, preparation, and testing. Let’s look at how to set fan airflow based on the needs of the equipment in both cooling and heating mode.

Model HBS-430 and HBS-431 blast dampers are designed to protect against blasts and any instantaneous pressure changes. 

The LED attachment for the Powerfoil X2.0 industrial ceiling fan produces up to 20,700 lumens, equal to the light output of 25 60-W incandescent bulbs. 

Start testing the right way and make sure you have a complete list of possibilities. Otherwise, you’re guessing at the solution and possibly creating more problems. Remember: if you don’t measure, you’re guessing.

The SelectCycler System— a cost-effective, whole-house mechanical ventilation solution that complies with ASHRAE 62.2 — combines parts of central fan integrated and exhaust fan ventilation to provide an energy-efficient solution for supply or balanced ventilation. 

Smartcool Systems Inc. announced that the company has delivered its first wireless demand control ventilation (DCV) system. The installation was a three-way collaboration between Smartcool Systems, Airtest Technologies Inc., and Total Energy Concepts Inc.

The John Wayne Birthplace is the only museum dedicated to John Wayne and contains more than $2 million worth of artifacts. So far, the HVAC design has proven more than capable in terms of occupant comfort, sustainable operation, and protection of artifacts.
