The majority of residential and commercial air conditioning units include throwaway fiberglass media filters. This project will replaces these filters. In principle, it captures a larger amount of airborne contaminants, captures smaller size contaminants, and operates at a lower air pressure drop...

This is a paper assessment of a site with diverse and plentiful opportunities for energy savings through the application of advanced technologies among its lighting and mechanical systems. The project is aimed at identifying the potential energy efficient opportunities with special focus in...

Variable Refrigerant Flow (VRF) systems are fundamentally different from unitary or other types of traditional HVAC systems. The space is cooled or heated directly by circulating refrigerant to evaporators located near or within the conditioned space. The system will replace electric resistance...

Blowers are widely used by industrial customers for various industrial processes. According to the Pacific Gas and Electric Company’s 2006 study, blower (and fan) consumes approximately 1,300 gigawatt hours (GWh) per year in SCE’s service area alone. This is fourth largest electric energy...

The goals of this project are to develop market understanding of the medium commercial segment – to include the key organizational, operational and decision-making characteristics and drivers. Additionally, whole building performance, equipment and system characteristics of this segment will be...

Evaluate the benefits of using a liquid desiccant system in an actual supermarket to lower and maintain indoor air relative...

Evaluate the performance of standard and high efficiency A/C units at hot and dry conditions. The assessment involved testing pairs of 3-ton split and 5-ton RTUs. Each pair consisted of standard and high efficiency...

A hybrid AC and DC platform that is being designed as an open architecture focused on reducing or eliminating inefficient AC to DC conversions between power sources and light sources by converting and distributing power in DC. This platform is designed to improve reliability and energy efficiency...

Evaluate a new piece of cooking equipment. At least one manufacturer has built a prototype to replace the existing unit, testing is needed to compare performance based on efficiency and dissipation of heat to the surrounding space. In addition, this study will be determining the proper sizing of...

Recessed LED luminaires, also known as lay-ins or troffers, feature an LED light engine in a traditional recessed luminaire form factor with dimensions 2'x2' and 2'x4'. This lab evaluation project will compare the light characteristics of the LED versus a linear fluorescent fixture of the same size...
