Environmental Performance Monitoring at Rowan House Passivhaus Building

We have finished installing all of the sensors and monitoring equipment at Rowan House and finished the air permeability testing and MVHR balance checks.   Monitoring is now underway.  We will be looking forward to receiving some objective data to see how these flats are performing.  As with Knights Place (see Knights Place blog below) the aim of this study is to monitor the following:

  • Air quality over 2 winters and 2 summers via CO2 sensors in the bedroom and living room
  • Air temperature and humidity monitoring over the 2 year period
  • Energy consumption of all the electrical sub circuits - cooking, ventilation, small power, lights etc
  • Solar hot water panel energy monitoring
  • Air permeability re-tests in the first year and second year after handover
  • Mechanical ventilation with heat recovery (MVHR) monitoring - testing air volumes over time, power efficiency of the unit in use, heat recovery efficiency during use
  • Infrared surveys and fabric dynamic heat flux tests
  • Occupant surveys and BUS questionnaires
  • EMF Studies to test the low EMF design
  • Daylight Studies

As results come in we will post them on our blog - keep an eye out, it should be interesting.
