Quality installation and maintenance sensitivity studies in heat pumps

A recent report from the ETI dealing with heat pumps (HPT) investigates heat pump faults commonly found in operating equipment, and assesses the relative capacity and efficiency degradations caused by these faults.  The resultant effort is aimed at positioning stakeholders to better understand how installation and maintenance practices affect heat pump performance.  Download from the HPT website here.

Impact of 'phase-out' regulations on lighting markets

An updated benchmarking report and a Policy Brief summary from the ETI focusing on efficiency of end-use equipment (4E) updates the results of the domestic lighting benchmarking report published in 2011 based on new data that gives insight into more recent market trends. Download the 4E report from their website here.

Modeling, design, and optimisation of net-zero energy buildings

This recent publication is the result of a joint project between the ETIs on solar heating and cooling (SHC) and efficiency in buildings and communities (EBC). The objective of the project was to study current net-zero, near net-zero and very low energy buildings and to develop a common undestanding, methodology, tools, innovative solutions and industry guidelines.
