LETI’s plan for retrofit energy targets

The energy demand of our homes must be reduced significantly to make a net-zero future viable, but for a high proportion of existing buildings this will be challenging. Passivhaus Trust’s John Palmer says upcoming LETI guidance will show professionals what is possible

The realistic route to zero carbon

To achieve carbon reduction targets, Chris Twinn says the UK should be looking at large-scale offsite renewables and achievable building performance targets that are rigorously upheld

Building resilience into net-zero schools

Schools designed today must withstand future climate change. Tim Taylor, Joe Jack Williams and Paula Morgenstern, from CIBSE School Design Group, look at the likelihood of them overheating

Net gains – retrofitting scenarios for net zero carbon

Retrofitting homes to be net-zero carbon is one of the great challenges of the new decade. Radwa Salem applies the existing nZEB standard to two dwelling types to assess its suitability and predict the overheating risk of targeting net zero

What is the most efficient system for heating zero carbon homes?

What is the most effective way of heating our future zero carbon homes? Chris Twinn has been researching the issue for five years and has found that standalone ‘autonomous’ heat recovery systems offer the most benefits when considering high-density homes
