Multi-Family Ventilation Update
Due to the historical dominance of single-family construction in California, multi-family buildings have been largely overlooked by the building code improvement process. As a result, the unique characteristics of these buildings are either unaddressed or forced to adhere to guidelines developed for entirely different purposes. For example, the ventilation rate required for an identical apartment, with only an additional story is 2 times the amount (from a 3-story building to a 4-story building). This may be a safe and easy to implement guideline for commercial buildings that range from moderate to heavy occupancy rates, but for multi-family buildings, this amounts to significant over-ventilation and increased energy use.
The Multi-Family Ventilation project, which is part of a larger PIER funded project, looks to address several code relevant measures specific to multi-family buildings. The project investigates and identifies the unique HVAC challenges, particularly ventilation requirements and indoor air quality, encountered in multi-family buildings. The result is a set of code change guidelines that include lower ventilation rates for high rise buildings to equal that of low rise buildings, and changing requirements for buildings with central shafts to auto-balance ventilation between floors, and have the ductwork manually or automatically sealed.
WCEC has completed its research on this project, and a shorter version of the final report is available to read here:

Emerging Technolgies Summit: October 20-22, 2014
What is the ET Summit?
From October 20-22, more than 500 stakeholders in the energy efficiency and demand response emerging technologies sector will gather for an interactive conference at the Parc 55 Hotel in San Francisco to learn, ideate and debate the intersection of utility programs, technology, market drivers, customer engagement, policy and implementation in order to impact the advancement and adoption of emerging technologies.
The ET Summit's presenting Sponsor is The Emerging Technologies Coordinating Council (ETCC). To help achieve the state’s ambitious energy savings goals, Pacific Gas and Electric Company, Southern California Edison, Southern California Gas Company, San Diego Gas & Electric, Sacramento Municipal Utility District, the California Energy Commission with oversight from the California Public Utilities Commission created the ETCC.
The ETCC provides a collaborative forum for its members’ to exchange information on opportunities and results from their Emerging Technologies activities. Efforts are focused on identification, assessment, and support for commercialization of energy-reducing technologies, such as advanced lighting, water heating, and air-conditioning systems, for residential, commercial, agricultural and industrial customers. ETCC members are committed to helping achieve California’s energy-reduction goals by screening potential technologies, assessing them to validate performance and customer acceptance, performing in-situ demonstrations and recommending the proven winners for IOU customer education and rebate programs. The ETCC is particularly interested in technologies that offer large energy savings and rapid market penetration.
