Webinar #4 - How and what can we learn from verifying energy savings first estimated with engineering calculations? (Part 2)

Webinar #4 - March 5, 2019 - 11:00 to 12:15 am CET

You will find the webinar detailed program and presentations at the bottom of this page.

The EPATEE project dedicates two experience sharing webinars to the comparison of energy savings based on engineering calculations with energy savings determined from metered energy consumption. The first part – see webinar #3 - presented two examples of ex-post evaluations that tackled this issue.

This webinar #4 provided a complementary experience from studies using large databases of metered energy consumption by presenting the following cases:

  • Case 1: Energy savings from renovations in the Dutch non-profit housing sector, with a statistical analysis of the differences between results based on the Energy Performance Certificates, and results based on metered energy consumption.

Presented by Prof. Laure Itard, Chair Building Energy Epidemiology, Delft University of Technology (Netherlands)

  • Case 2: Analysis of the differences between energy consumption from building energy stock models, Energy Performance Certificates, and the impact of efficiency measures using metered data from the UK National Energy Efficiency Data-framework (NEED)

Presented by Dr. Alex Summerfiel, Energy Institute, University College of London (UK)

The webinar dealt with the following questions:

  • What data and methods could be used to assess energy savings?
  • How could the “metered” energy savings be compared with the “estimated” energy savings?
  • What difficulties were encountered?
  • What can be learnt in terms of evaluation practices for future evaluations?
