This project is a demonstration and comparison study between conventional Normalized Metered Energy Consumption (NMEC) analysis and a Measurement & Verification (M&V) method which enhances NMEC with rapid & repeatable interventions. The Enhanced NMEC (E-NMEC) with Rapid Interventions (RI) is...
The proposed project is a demonstration of an emerging high efficiency heat pump product for multifamily space conditioning applications. This project will demonstrate the application of Double Ducted Packaged Terminal Heat Pumps (DDPTHP) in a low-income multifamily new construction project in the...
Many existing non-residential rooftop package units (RTU) including heat pumps do not have monitoring capabilities where temperature, pressure, and energy are known in real time. This is the typical case found in commercial primary and secondary schools within public school districts. The target...
AESC and ASK Energy propose a California-focused field demonstration and market assessment of a packaged, modular, all-electric CO2 centralized heat pump water heater with load shift capabilities designed for commercial and multi-family buildings. The proposed technology supports electrification...
This project is an open source supervisory control technology development and demonstration of ASHRAE Guideline 36 (G36), ASHRAE 2021.
The promise of G36 is that the standardization of the sequence of operations (SOO) allows manufacturers to program and centrally test the control logic and then...
The High Efficiency Dehumidification System (HEDS) technology of interest is a new and patented technology developed in Southern California with energy savings potential for air handlers with chilled water cooling and hot water reheat. The technology was first developed to address dehumidification...
Variable air volume (VAV) HVAC systems dominate the commercial building market but have widely varying performance, with a well-documented performance gap between best-practice and typical operation. Two recent studies by Lawrence Berkeley National Lab and the California Energy Commission (CEC)...
A new energy-saving product called an air management system (AMS) has been developed as a drop-in replacement for compressed air filter-regulator-lubricator (FRL) assemblies. The AMS saves energy by reducing pressure to large pneumatic end-uses during idling and cutting off air supply during...
This field demonstration project in a full service restaurant involves pre-retrofit energy monitoring of existing domestic hot water systems, the installation of single-pass air-source heat pumps (HPs) and other efficiency measures, and post-monitoring of optimized systems. Hot water is primarily...
The majority of building power distribution systems use alternating current (AC). This significantly influences the design of connected, building system components and appliances such as direct current (DC) appliances. With the proliferation of DC devices as standard design elements across many...
