One benefit of joining iSERVcmb is the availability of case studies. We will create a number of case studies for those participants which are willing to join iSERVcmb unanonymously. In order to provide you with a feeling how these publications look like, we decided to upload our case study report on McKenzie House in Cardiff, UK. The report summarizes the results of Cardiff University’s participation to the iSERVcmb project with regard to its HVAC system energy consumption. It refers to the period from 2003 to 2012.
