Improving building performance in the UK’s existing buildings

Brought to you by the CIBSE Heritage Group

Building services appear very late in the history of construction, and we are still feeling our way towards the best ways of optimising their potential for improving the usability of buildings without causing unexpected problems for the fabric (such as condensation) or burning excess amounts of energy. Traditionally constructed historic buildings show us the limits of what can be achieved by fabric alone, and present us with the challenges of integrating services that cater for 21st – century demands for comfort and utility. Meanwhile, listed buildings of modern construction (such as the Lloyds building in London, where the servicing is critical to the design) help to underline other problems being faced by buildings of all types. These sessions will work through the underlying issues, finishing with a plenary that will attempt to unlock some of blockages that are currently preventing building services from reaching their full potential.

TD1 Where are we with services and sustainability in our existing buildings?

Why we need to look at buildings holistically if we’re going to make them usable, long-lived – and sustainable Embodied energy: where you’re going, and how to think it through Services in historic buildings are not just about “high end” examples; good outcomes are the same for all buildings Building Performance Triangle (need to look at fabric and people as Continue Reading »


10:25 - 11:20

TD2 How and why the three elements to the Building Performance Triangle impact outcomes in building performance

How and why the fabric is critical to outcomes How do we assess the performance of the building fabric? How does that interact with the assessment of people and services? What can go wrong if you get it wrong Identifying the goals Measuring and monitoring Speaker: Dr Nick Baker, Building Physicist (Cambridge University, retired) How and why the people are critical Continue Reading »

TD3 Case studies & plenary: What is stopping us doing this properly?

Case Studies  • Lessons in sustainability in practical circumstances • What are the energy savings to be made? • Case studies from a variety of buildings Speaker: Katy Lithgow, Head Conservator, National Trust PLENARY: What is stopping us doing this properly? In this panel session, our speakers will take questions and comments from the audience, all the while attempting to reach Continue Reading »
