Nov. 1-2: Solutions to Building NZE in Alaska

Nov. 1-2 Workshop: Practical Solutions for Building Net Zero Energy in Alaska

Net Zero Energy homes produce as much energy as they use. Join Fairbanks builder Thorsten Chlupp for this workshop looking at Net Zero Energy building in Alaska. Thorsten will discuss his experiences building and living in NZE homes in Alaska. This workshop will cover practical lessons that explore limitations and solutions for Passive House and Zero Energy buildings in the heating-dominated climate of Alaska. We will investigate how to overcome the hurdles of building high-efficiency structures in a cold climate, including lessons learned from building solar heated homes at Latitude 64. Webinar Available Saturday.

Thorsten Chlupp is the founder and owner of Arctic Sun and REINA, LLC, and works closely with the Cold Climate Housing Research Center in Fairbanks, Alaska. He has given many presentations, talks and seminars about Green Building, Passive House, Zero Energy Design and Sustainable Building approaches throughout the states and overseas. With a great passion for building science, his focus has been to develop and build high performing buildings with integrated renewable energy systems with a strong focus on solar and annual heat storage. He is absolutely convinced we need to develop truly sustainable buildings and communities now, while we have the time and resources to do so.
