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

A condensing guide to CHP efficiency

CHP can offer savings in applications with high, constant heat demand, but how designers integrate it will impact on the benefits. Remeha’s Ryan Kirkwood considers the options in the first of a two-part series

Case study: One Angel Square, Northampton

Robust modelling and an intelligent redesign enabled BDP to retain natural ventilation in Northamptonshire County Council’s new offices. Andy Pearson finds out how collaborative value engineering resulted in a CIBSE Building Performance Award

Testing the water – designing the UK’s first Passivhaus swimming pool

The UK’s first Passivhaus swimming pool, currently being developed by Exeter City Council, seeks to halve energy use and create a chemical-free, healthy environment. Andy Pearson speaks to project team members about the innovative design that aims to set new Passivhaus standards for pools

Completing the picture – London Energy Map

The London Energy Map project tried to provide a clearer picture of building energy use in the capital by analysing the existing dataset. Dora Ma and Ed Cremin, of Etude, analyse the numbers

The Passivhaus that Max Fordham built

Max Fordham’s Passivhaus house features automated insulated shutters, developed to reduce night-time heat losses and to achieve an energy balance between gains and losses on a cold winter’s night. Liza Young reports
