Leakage to the outdoors has always been a requirement for LEED for Homes. However, leakage between units has not been accounted for. Although there is typically not a significant energy penalty for leakage between units, excessive connectivity between units decreases the indoor environmental quality of occupants by allowing a pathway for odor and sound transfer.

Additional Questions

  • Was it difficult to seal the units sufficiently?
  • Did any units fail initially? If so, what actions were taken to lower the envelope leakage?
  • What challenges occurred when performing the envelope leakage test?
  • What equipment was used to test the envelope leakage area (make and model number)?
