A Tale of Two Buildings

A Tale of Two Buildings

Are Energy Performance Certificates (EPCs) a true indicator of energy efficiency?

Whilst not denying the value of EPCs, ‘A Tale of Two Buildings’ report from Jones Lang LaSalle and the Better Buildings Partnership (BBP) emphasises the importance of measuring and achieving reductions in actual energy consumption.

Using data gathered from over 200 buildings over the past four years, Jones Lang LaSalle has worked with the BBP to measure the actual energy performance of its members' managed properties in London with surprising results.

Based on our findings, we tell the tale of two buildings with very different EPC ratings and uncover which is actually more energy efficient.

The report also considers:

Are EPCs alone sufficient to deliver the Government’s targets to ‘de-carbonise’ the UK’s built environment?

How successfully is the property industry tackling the issue of reducing actual energy consumption?

What do we do now? Recommendations and guidance for both owners and occupiers.

This report provides yet more evidence for the inaccuracies in EPCs and, more importantly, the benefits of in-use energy monitoring. This was a theme at some of the talks in Ecobuild 2013 and points towards a need for mandatory DECs to motivate a culture of post-occupancy monitoring and improvements.

Opinion

 

EPCs have been criticised for a lack of accuracy, or alignment with actual operational energy use, although they remain an important tool for raising awareness and giving an indication of how a home or building is designed to perform. 

The Energy Act 2012 put EPCs centre stage by passing legislation that is expected to ban the letting of F and G rated buildings from 2018 onwards, in both domestic and commercial markets – a principle which UK-GBC fully supports. Read more about ‘minimum performance standards’ here.
