19-20 March 2018, Workshop, Wellington (NZ) - Towards higher-performing buildings: The role of airtightness and ventilation
Wellington, New Zealand 03/19/2018 - 08:00

The objective of this workshop is to discuss and identify ways to improve the quality of our homes with respect to airtightness and ventilation, as well as discussing the impact suboptimal performance has on energy consumption and health of the occupants. Also of interest are the impacts of mandatory airtightness targets and how best to implement these, if at all.

The objective of this workshop is to discuss and identify ways to improve the quality of our homes with respect to airtightness and ventilation, as well as discussing the impact suboptimal performance has on energy consumption and health of the occupants. Also of interest are the impacts of mandatory airtightness targets and how best to implement these, if at all.



Specific topics



  • Indoor air quality in schools and residential buildings

  • Ventilation and its impact on energy and health outcomes for occupants

  • Airtightness of New Zealand buildings - trends and requirements

The workshop discussions will be based on detailed presentations from international and national researchers. Interaction between participants will allow exchange of ideas and experiences.



Context



New Zealand homes and apartments have become more and more airtight and have reached a level of airtightness that requires dedicated ventilation. Despite the fact that there is no airtightness requirement in the New Zealand Building Code, new homes regularly reach an airtightness level of 2-3.5 ACH50. This can be a welcome trend as it allows controlled ventilation and therefore control of the energy demand of the building. Many newly built homes, however, experience excess moisture and mould problems in living areas and/or roof cavities, due to a combination of occupant behaviour and a lack of ventilation.



The goals of a healthy home environment and energy efficiency can sometimes pull in opposite directions, requiring us to find a trade-off between health and energy saving.



Do we need dedicated airtightness and ventilation targets in the Building Code to reach an optimal set point for ventilation related energy use and health outcomes? How can this be achieved?



Organisers



The workshop is organised by INIVE EEIG on behalf of AIVC in cooperation with ASHRAE and BRANZ.
