This paper, published as part of the 2024 Summer Study for Energy Efficiency in Buildings proceedings, broadly addresses considerations for the design of community scale sustainability and resilience strategies including which sustainable and resilient features are best managed at the individual building level versus at a larger community scale.

AESC conducted this technology evaluation, the Virtual Power Plant (VPP) Project, with SDG&E’s Emerging Technology Program. The VPP was an initiative to strengthen resiliency and electric reliability in the community of Shelter Valley in East San Diego County.

ASK Energy, Ecotope, and AESC conducted this CalNEXT study on central heat pump water heater systems in two low-income, high-rise multifamily buildings in San Francisco.

With support from CalNEXT, AESC and partners VEIC and ASK Energy analyzed data on the mobile and manufactured housing (MMH) sector to better understand technical and market barriers to electrification.

In collaboration with the CalNEXT program and partners, AESC performed a market characterization of California Senate Bill No. 1383 (SB1383) Landfill Diversion compliance solutions under consideration or are in planning by wastewater treatment facilities.

This market evaluation study by AESC for CalNEXT covers solar assisted heat pumps, a technology that promises to provide supplemental, carbon-free heating to any variable-speed pump air conditioner in the 2-ton to 10-ton range.

Prepared by AESC, this CalNEXT market study report assesses the viability of electrifying heating hot water (HHW) systems in large commercial buildings, with the focus on air-to-water heat pumps (AWHP).

This report prepared by AESC outlines the findings of a CalNEXT market study on industrial heat pumps (IHP) for eleven industrial subsectors.

AESC investigates the energy impact of ultraviolet germicidal irradiation (UVGI) disinfection technology.

AESC conducts a quick analysis of Tier 2 advanced power strips, investigating their ability to drive energy savings in residential and commercial settings.

AESC further explores the energy and cost savings of permanent magnet synchronous fan motors in refrigerated display cases. This study was performed on behalf of SCE’s Emerging Technologies program.

Building upon past research, AESC engineers look into demand response opportunities for water and wastewater treatment plants.

AESC investigates if a new sealing technique for crawl spaces and attics can provide for better building envelope air tightness, reduce duct leakage loads, reduce humidity levels, and improved overall air quality. Results indicate potential solutions for single-family homes with high envelope leakage or high HVAC energy usage.

AESC conducts field tests for three emerging evaporative cooling technologies.

AESC tests the efficacy of an HVAC management system designed for commercial rooftop units and split system applications. Results include implications for improved thermal comfort and energy demand.

AESC conducts a field evaluation of solar powered, ductless mini-split air conditioning systems in a commercial setting.

AESC investigates the efficacy of two Tier 2 advanced power strip models in 98 residential homes.
