This two day training will focus on design and construction details to achieve net-zero energy use in new buildings. Join Ian Shapiro, founder of Taitem Engineering and co-author of the book Green Building Illustrated (Wiley, 2014) and Liz Walker, co-founder of EcoVillage Ithaca, and Executive Director of its educational arm,Learn@EcoVillageas they address fundamentals and strategies for zero energy design. Ecovillage and cohousing concepts will be covered as well as site visits to homes and community buildings at Ecovillage’s three cohousing neighborhoods, emphasizing different green building approaches, styles and details, culminating in the newest neighborhood called TREE, the largest Passivhaus development in North America, which includes a number of net zero homes.

Learning Objectives:

  • Learn the fundamentals of design to achieve net-zero energy in new buildings, including heating/cooling options, hot water strategies, insulation and window design, lighting and electrical load for net-zero. 
  • Learn specific construction details which help to achieve net-zero energy, including techniques to achieve low infiltration and to minimize thermal bridging.
  • Understand the concepts of cohousing and ecovillages as examples of neighborhood level design for sustainability.
  • Learn options for measuring and verifying net-zero performance, and approaches to maintain persistent net-zero performance
