This project evaluated tunable white LED fixtures (troffers and pendants) with integrated controls, including daylight dimming, to determine visual and circadian performance and energy usage in commercial office space. The analysis culminated in information/recommendations for connected, tunable...

Compare this hybrid exhaust fan airflow and power consumption to other products in the exhaust fan category. A test apparatus will be built to test powered exhaust fans delivering required airflow and static. The fan will also be installed in the field to determine a "real world" performance and...
