Fellow ESF Members and Friends,
 
Engineers for a Sustainable Future (ESF) is pleased to announce a presentation from Gertrude Villaverde on May 9 at noon.  Gertrude will speak on "Efficient HVAC Design for Healthy Indoor Environments".  This email is intended to be a reminder for virtual attendance at our meeting. The Zoom link is below.
 
Speaker: Gertrude Villaverde, CEM, CMVP
 
At Energy 350, Gertrude supports multiple contracts with technical analysis in production efficiency for industrial facilities, efficiency upgrades for existing buildings, and market transformation for regional energy efficiency. Gertrude is a Certified Energy Manager (CEM) and a Certified Measurement & Verification Professional (CMVP). She has an Honors Bachelor of Science in Energy Systems Engineering from Oregon State University – Cascades. She’s been involved with the Association of Energy Engineers (AEE) since 2015 and is currently president of the Columbia River Chapter in Portland, OR.
 
Presentation: Efficient HVAC Design for Healthy Indoor Environments
 
This session will present a proven HVAC system approach called very high efficiency dedicated outside air systems (very high efficiency DOAS). Configured to optimize HVAC performance, very high efficiency DOAS combines high-efficiency equipment with design best practices to improve occupant comfort and indoor air quality while significantly reducing energy use. In partnership with local utilities and HVAC experts, this system approach has been installed and monitored in 12 small-to-medium commercial buildings that resulted in an average 69% reduction in HVAC energy use and a 48% reduction in whole-building energy use over code minimum of the existing equipment (often a packaged RTU). Attendees will learn the cost and energy savings outcomes of these Northwest-based projects.
