MAY 21 WORKSHOP
Potential use of nuna (sod) as a local building material. This is a sustainable, locally produced material which was traditionally piled at the base of buildings and used for both structural and insulation value.
Importance of considering high efficiency appliances as a significant way of addressing many current housing issues dealing with water consumption and sewage output.
Lesson learned: need to consider human error in installation or operation when deciding where piping goes, and how to protect from freezing temperature. What would be the damages and consequences if it fails.
Special considerations need to be made regarding sewage.
Sewer and water pipe freeze up remains one of the largest risks to housing.
Local practices introduce a high level of grease and food particles into the drainage/septic system through cultural practices surrounding food and materials preparation (animal hide skinning, waste product removal, etc.). Any waste water removal system involved in the building will need to either filter heavy grease buildup or have sufficient flow to remove them from the system (ie. low flow toilets might not be an option). Grey water and compostable toilets use is not prevalent in the community (CHARS has two composting toilets installed), but there is lots of interest for exploring these options..
How are solar panels impacted by dust accumulation?
Passive solar is incredibly effective in the North. Due to the higher levels of sun, It is often too effective, and has to be mitigated by opening windows and blocking the sun.
Waste heat recovery is a valid option for the Arctic. Some residents are puling waste heat from their boilers to keep trucks warm, etc. However, it would be only to use heat within building – transmission line will cause a lot heat loss, especially in winter.
