“Mind the Gap” – The difference in performance between design and the building “in-use”

Time: 14:40 – 15:10

Date: Day 2 – 23rd November 2017 Theatre: Water and Energy Strategy

I am chairing an expert panel who are discussing why “We have the ability to design good buildings and the knowledge to operate them in an effective and efficient manner – so why doesn’t it happen?”

As we drive the performance of our building stock, it is becoming clear that one of the key challenges we must address is narrowing the gap between design and actual performance. The industry needs support to ensure they understand how the building will perform in operation. If we don’t, the gap in performance can be as big as 200-450% greater than predicted. With project costs squeezed and ‘value engineered’, all too often performance suffers.

This expert panel will discuss the issues such as:

  • Designing for compliance;
  • Commissioning and soft landings;
  • Benchmarks and real performance
