Active thermal solutions

Active solutions come into play when we used a maximum of passive solutions and they supplement them:

  1. Directional sunscreen to replace the shutters and curtains to have more sun that can penetrate during winter (replacing the curtains) and protection from the summer sun at certain times where the hoverhangs do not work, including west in the evening
  2. Heat recovery ventilation to take as much heat as possible from the extracted air during winter.
  3. Solar waterheater/heater. The waterheater will be based on builditsolar, but there will be some modifications because of the greyater heat exchanger. Indeed, the scheme would cause problems provided in yields if connected on greywater heat exchanger. Here is the description of the system:

I chose to build the solar water heater that way for several reasons:
