Friday, May 31, 2013
Noon to 1:30pm
Free and open to all; bring your lunch.

1.5 CES/HSW LUs

A Committee on the Environment program.

This Net Zero Energy project case study will present the design, construction and performance of the first HERS-certified NZE new home in California, which achieved special recognition by the CEC.  This ground-breaking project is now known as “The Hair Dryer Home” since it can be heated with only a hair dryer as documented in a YouTube video. The presentation will highlight:

  • A NZE design framework; energy loads analysis, conservation and production
  • Passive House design as a fundamental conservation strategy
  • Key climate-specific design issues and strategies
  • Performance results from DOE Building America program monitoring data
  • Energy offset opportunities for synergistic transportation fuel/carbon reduction.

Learning Objectives: 

  • Understand the fundamentals,  issues and challenges of NZE design
  • How do Passive House methodologies and standards contribute to NZE design
  • Recognize the important new characteristics and behaviors of super-insulated buildings and their mechanical systems
  • Understand the potential for building and transportation energy synergies
