106 NET ZERO


energy requirements without a viable path to do so will negate achieving any energy efficiency at all.’


‘People need to be regulated and to self- regulate, so certification is always going to be a necessity, but how you arrive at that standard needs to be tangible,’ stresses Simon Henley, principal at Henley Halebrown. ‘Te flaw with some schemes is you have to utilise materials that require more energy in their manufacture to achieve relatively small gains

during use. What we need is a whole-life carbon model without the use of offsets.’ Off-setting is almost universally despised. As Henley says: ‘Off-setting is neither palpable nor comprehensible and doesn’t engage people – it is just sleight of hand. We have to return to being thrifty, and that’s about more than sticking a label on a building. Yes, you can reach net zero with only a spreadsheet, but the solution would be so abstract that the people who are going to use the building are

Not every building can reasonably reach net zero, and yet may still have a history worth preserving. Compromises were made to preserve Sir Giles Gilbert’s Grade II* Battersea Power Station both in terms of architectural interventions and sustainability. WilkinsonEyre saved the embodied carbon, improved the thermal performance and added more eficient services, as well as leaving the large turbine halls unheated, successfully giving the landmark, empty for 30 years, a new lease of life.
