Overview

  • Rabbits cannot tolerate temperatures greater than 30 degC, this is why they live underground.
  • In this project we experiment with the six Passive House principles to keep internal temperatures as constant as possible.
  • The six Passive House principles are:
    • air tightness - air leaks result in excessive temperature gains or losses
    • insulation - stops thermal leakage through roofs, walls and floors
    • thermal mass - slows heat gain or heat loss
    • double glazed windows - is the equivalent of insulation for windows
    • north facing windows for heat gain
    • eliminating thermal bridges

Discovery learning experiments

  • In this project we will experiment with a foam box that we can modify using the six Passive House principles.
  • To monitor the effects of the six Principles we will use a temperature sensor
  • We will also include two controls:
    • one temperature sensor in an unmodified foam box
    • one temperature sensor measuring atmospheric temperature changes

Experiment 1 - air tightness

  • Using PVA glue, paint the inside and outside surfaces of the foam box with two coats of PVA glue
  • Foam often has small micropores that allows air to pass through
  • We call this an open foam structure
  • Once dry, the PVA coating should help create a box that is more air tight.
  • This should improve thermal performance in comparison to the two controls.
