AEA West

AEA opened its West Coast office in 2010 and has since helped lead the charge towards a clean, efficient, and equitable zero net carbon multifamily building stock in California.  We are deeply committed to addressing the challenges of climate change by delivering the benefits of energy efficiency and solar to the communities that are most susceptible to climate impacts and have the fewest resources available to them to protect themselves from the consequences.  With a focus on improving the lives of low and moderate income Californians AEA West aims to rapidly scale the delivery of high performance net zero carbon buildings through the effective and efficient delivery of energy programs, cutting edge research and demonstration projects, and educating policy makers, property owners, contractors and the general public.

AEA West is currently involved in implementing whole building multifamily retrofit programs throughout California, most of which serve both low income and market rate properties.  In each of these programs AEA works directly with property owners and design teams to schedule and perform on-site property assessments, develop energy models and savings calculations, produce comprehensive scopes of work, and document all findings and recommendations in detailed energy audit reports.  Additionally, for most of these programs AEA assists owners in accessing financing and/or rebates; develops detailed measure specifications; communicates the findings to property owners, contractors, program administrators and other key stakeholders; assists owners with contractor procurement; reviews and evaluates contractor bids to ensure cost control; and performs on-site interim construction inspections and final post construction verification inspections.

Research and Development

Research and Demonstration Projects:  Since 1994 AEA has been involved in a variety of research and demonstration projects, primarily with funding support from the California Energy Commission, U.S. Department of Energy, New York State Energy Research & Development Authority (NYSERDA), and NYS Division of Housing & Community Renewal and others.  Current projects in CA include:

  • EPC–15-097: Achieving Zero Net Energy in Multifamily Buildings.  AEA is currently partnered with Build It Green, Stone Energy Associates, Redwood Energy, and LBNL in the CEC-funded research study entitled Achieving Zero Net Energy in Multifamily Buildings, EPIC 15-097, which aims to demonstrate the technical and economic potential for optimized ZNE construction practices in new multifamily buildings through four demonstration projects.  The project will inform best practices as well as codes and standards and will communicate lessons learned to the multifamily design and construction community in a way that facilitates broader adoption of ZNE practices with reduced performance risk.  AEA leads the measurement and verification component of the project and is responsible for monitoring equipment installations, data retrieval, cleaning, and analysis associated with the HVAC and water heating-related mechanical systems.  Project Announcement
  • EPC–15-308: Integrating Smart Ceiling Fans and Communicating Thermostats to Provide Energy-Efficiency Comfort.  This project seeks to develop optimal ways to integrate commercially available “smart” ceiling fans and thermostats now on the market, and to evaluate how they impact energy use and comfort in multi-family residential and small commercial buildings. The CEC funded project team is led by UC Berkeley’s Center for the Built Environment (CBE), and includes TRC, AEA, and Big Ass Solutions (BAS). 

A new generation of smart, internet-enabled building products offer opportunities to improve comfort while at the same time reducing customers’ energy use and utility costs. However a challenge remains in how to describe the benefits they offer, and support the adoption of such integrated solutions by customers. The Berkeley-led project will gain insights into these questions through a series of laboratory tests and field demonstrations, using BAS ceiling fans with “SenseME” controls that respond to the environment and occupants’ preferences, integrated with communicating and learning thermostats. The demonstration sites will include dwelling units, common areas, and fitness facilities, in historically under-served low-income multifamily housing in California. A series of complimentary laboratory studies will conducted to create a new standardized method for testing and rating fans for energy and comfort performance, helping manufacturers to refine their offerings, and customers to make informed choices.  Project Page

  • EPC–17-304: Mass Deployment Model for ZNE Retrofits:  In partnership with Prospect Silicon Valley, Rocky Mountain Institute, the UC Davis Energy Efficiency Center, David Baker Architects, Integral Group, Stone Energy Associates, San Francisco Department of the Environment, and the California Housing Partnership, AEA was recently awarded a CEC EPIC research and demonstration grant that will demonstrate the design and rapid delivery of affordable Integrated ZNE Retrofit Packages with a business model to drive scale.  AEA will serve as the Principal Investigator and will oversee the design, installation, and verification of all four advanced technology demonstration projects.  The program targets a 50% cost reduction on the installed measures that will deliver 50% reduction in energy use through standardization of the retrofit solution, combined with a market facilitation platform that aggregates demand and empowers it to negotiate with and inspire innovation amongst suppliers.  The program includes an innovative performance assurance mechanism that expands the availability of affordable financing for deeper efficiency savings, unlocking the potential for rapid adoption in the market.  The project will be demonstrated in disadvantaged communities across various climate zones and will ensure they benefit long-term by transforming the building stock most relevant to this community – multifamily residential buildings. The program will unlock the market to innovate productized and mass manufactured “Integrated ZNE Retrofit Packages” to transform the State’s over 420,000 low-income housing units, and ultimately the 13.5 million single-family and multifamily housing units in California. The project will precipitate roughly $7.7 billion in utility cost reductions for Californian’s by 2030, 8.4 million metric tons of greenhouse gas emission reductions, and nearly 69 billion gallons of water savings.
  • PIR-16-012: Effective Kitchen Ventilation for Healthy ZNE Homes with Natural Gas Appliances.  The goal of this Lawrence Berkeley National Laboratory (LBNL) led project is to inform developers of residential building codes and standards that protect indoor air quality and health for ratepayers, focusing on kitchen ventilation requirements for California multifamily ZNE homes with natural gas. 

The project team will collect data and conduct analyses and simulations to inform the potential beneficiaries of changes to the building code requirements for kitchen ventilation. AEA will contribute to study design and protocol development, and will lead on project identification, recruitment of participating occupants, preparation and deployment of measurement and data logging devices, ventilation equipment characterization, execution of quality assurance procedures, data handling, documentation of fieldwork activities, and the reporting of field observations.
