New report on building energy efficiency renovations

The International Partnership for Energy Efficiency Cooperation (IPEEC) has been active promoting energy efficiency since its founding in 2009. Its membership now includes 17 of the Group of 20 (G20) economies, which represent over 80% of global energy use and over 80% of global greenhouse gas (GHG) emissions

IPEEC’s Buildings Energy Efficiency Task Group (BEET) has just released its sixth publication on energy efficiency in the buildings sector: BEET 6. The report provides an overview of regulatory policies for the renovation of existing buildings and complements the task group’s previous work, which focused on building energy performance metrics, codes and energy efficiency rating schemes.

Why focus on the renovation of existing buildings? While new buildings are being built in accordance with energy efficiency principles and low energy-consumption buildings are starting to reach a “critical mass”, a large portion of existing building stock is much less efficient. In 2014, buildings still accounted for over 30% of global final energy consumption and 55% of final electricity demand.

Implementing building energy codes to the renovation of existing building stock is particularly difficult due to the challenges that arise from varying perspectives and the competing goals of different stakeholders. However, case studies from the United Kingdom, Germany, France, Canada and Japan show us that it is possible – as long as the appropriate regulatory policies are in place. BEET 6 synthesises and highlights which policies have driven the most significant activity .

This report provides an overview of the key regulatory policies which have been used internationally to require improvements to existing commercial and residential buildings at the point of renovation, refurbishment, retrofit, alterations, or additions. This study, based on best practices and case studies, aims to identify the best strategies to reduce the energy consumption in existing building stock.
