Bridging the gap: gas-fired absorption heat pumps in America

In the US, an abundance of cheap gas and a high carbon intensity for grid electricity compared with Europe is driving a move towards gas-fired heat pumps in small buildings. Tim Dwyer looks at three papers on the technology that were presented at the ASHRAE Winter Conference in Orlando

Making the switch from gas-fired CHP to heat pump

Lower carbon factors for Grid electricity proposed for Part L are already in place in London. Andy Pearson looks at one scheme in North London where the design is switching from gas CHP to heat pump

Class control: optimising HVAC controls in schools

Poor HVAC controls can cost schools thousands of pounds in wasted energy. School teacher Chris Baker explains how he engaged with his students at Parrs Wood school to cut energy bills by £9,000 a year after extensive monitoring

Teeing up a heat pump retrofit at The Oxfordshire Golf Hotel & Spa

The Oxfordshire golf resort is investing £700,000 in a major services retrofit, including a solar array, that will see heat pumps replace oil-fired boilers and potentially deliver sufficient energy and resource savings to boost annual profits by up to 30%. Alex Smith looks at how the challenges were addressed

CIBSE Award winner: Armstrong Tango pumping solution

Armstrong left its mark on the judges with its commitment to the reduction of carbon emissions over the life-cycle of its Tango Parallel pumping solution, the independently verified performance of which also impressed

Case study: Cambridge Central Mosque

Cambridge’s elegant new mosque has comfort and sustainability at its heart thanks to the involvement of the environmental engineer at the project’s inception. Andy Pearson looks at how Skelly & Couch’s creative design worked with the grand scale of the prayer hall to provide natural ventilation and daylighting for more than 1,000 worshippers

In the hot seat: Interview with Dave Pearson

Large heat pump installations could change the way heat is generated in the UK and help decarbonise existing buildings in cities, says Star Renewable Energy’s David Pearson, who speaks to our journalist Andy Pearson
