The purpose of this project is to perform a laboratory assessment of fault detection and diagnostics technologies (onboard and in-field) on a packaged rooftop unit air...

This system eliminates the central engine room, long piping runs and associated parasitic losses with a traditional ammonia-based system. All components are energy optimized, fully automated, remotely monitored and auto DR ready. This assessment looks at low temperature (-15'F) refrigerated...

Verify the performance of two advanced indirect evaporative technologies as replacements for air-cooled DX cooling. Two field demonstrations will be undertaken to evaluate and validate the technologies. The units will be installed and monitored for a...

Produce chilled water for building cooling without the use of compressorized...

The pool pump system being evaluated is a hybrid AC and solar powered DC system. A DC pool pump is directly fed by PV panels installed on the roof of a building. An automatic digital motor controller changes the torque and speed of the DC motor based on the input power coming from the PV panels....

The Project Purpose is to identify lessons learned while retrofitting residential homes to ZNE levels. Observations in the field during the ZNE retrofit projects will form the basis of this report. The expected outcome of this project is to educate builders, trades people as well as other...

Laboratory test of an indirect evaporative pre-cooler on the outside air intake of a packaged AC unit, along with a direct evaporative pre-cooler on the AC unit's...

Develop test protocol for uniformly evaluating performance of AC unit condenser air evaporative pre-coolers. The purpose of this project is to establish a nationally-recognized performance standard for the different types of technologies designed to pre-cool AC unit condenser air, using water...

Cook and hold cabinets are ovens with the ability to cook the food product and switch to holding mode to maintain product temperature and freshness. Ovens will be tested in a laboratory setting. This project will encompass applying an industry-accepted standard test method to up to five different...

Conduct field evaluation of the performance of a novel approach to cooling dairy cows by installing hydronic heat exchanger panels beneath the manure free stall beds. The project will measure energy consumption of the new system relative to the baseline high-speed low-volume fans and feed lane...
