From an experienced builder and carpenter’s perspective, the course met my expectations and needs. I got the hands-on experience to complete my skill set to build my own timber frame straw bale house. By showing me the traditional alternatives that are not often found in the big box stores, it reinforced my desire to stop using and being exposed to toxic materials also, the course filled in the gaps in my training and education in regards to building science so that I can make high-performance envelopes from here on. I enjoyed the format and flow of the course. There was a good distribution of in-class and hands-on time and site visits. I was surprised that we could use multiple type of insulation and wall systems in the same building, a practice not common to the residential building industry. The course setting was appropriate since Peterborough is a beautiful town with lots to do and explore after and in between the classes. It is also host and near many natural buildings Based on the nature and pace of the course, I think that the course is well adapted for experienced builders such as myself that care about the environment and the health of the occupants. It is also a good intro for people that are motivated do-it-yourselfers who will take the time to experiment on their own before going full scale.
