Some of Thorsten's talks have been recorded and made available online. We are working on more educational videos that explain some of the systems we have developed and now utilize. Disclaimer: Lots of rambling, view at your own risk.

Sustainable Building and Community Design Course

Lecture by Arctic Sun's CEO Thorsten Chlupp

2011 PHIUS North American Passive House Conference

Presentations by Arctic Sun's CEO Thorsten Chlupp

All three presentations given at the last Passive House conference in Silver Springs, Maryland in October 2011 were recorded, and they will be available online. Currently, only the first talk is availabe. The link to the conference is: http://www.passivehouse.us/phc2011/main-schedule/ - there is also a link to 2010's talks in Portland.

Track 1: Cold Climate PH 101

Lecture by Arctic Sun's CEO Thorsten Chlupp
Run time:

Limitations to Solutions for PH buildings in our cold northern regions. Lessons learned from building solar heated homes at Latitude 64. What are the technical limitations, and how to overcome the hurdles of a cold climate in high efficiency buildings. Understanding the importance of windows: what glazing to choose, adding thermal shutters, thenintegrating them into buildings. Ventilation and supplemental heating strategies, best practices for cold climates, and tips and tricks from hard-learned lessons building in the Arctic.

Track 2: Searching for the Perfect Wall

Lecture by Arctic Sun's CEO Thorsten Chlupp
Run time:

An update on the ongoing research project analyzing a diffusion open wall system without a conventional vapor barrier at Latitude 64 (monitored by the Cold Climate Housing Research Center). Thermocouples, humidity sensors, and data loggers help demystify real world performance and provide facts over fiction. Datasets, performance, and a primer on: diffusion; airtightness; permeability; vapor drive; sorption; Lambda values; decrement delay; and, embodied energy in medium-weight, super-insulated walls, and their real world implications.

Track 3: Beyond Passive Home

Sustainable Shelters in an Unsustainable World

Lecture by Arctic Sun's CEO Thorsten Chlupp
Run time:

Super-insulated PH buildings, combined with an integral renewable energy system and a holistic and universal design approach, can create living shelters even in the most extreme climates. This is a look at: sustainable design; embodied energy and the bigger picture of energy in buildings; and, integrating natural materials, indoor plants, and living walls within buildings. What makes us human and our shelters to become our homes?
