The balance of power: the bivalent approach to heat pumps
Using a boiler to top up peak space heating in heat pump systems can save CO2 and costs, says Mitsubishi Electric’s Chris Newman, who gives examples of two configurations
Sound advice
Noise and vibration from HVAC systems such as large heat pumps can have a huge impact on occupant comfort. KP Acoustics Group’s Kyriakos Papanagiotou and Mason UK’s Adam Fox say CIBSE’s Guide B4, and early engagement with acoustic specialists, will give peace of mind
Lochinvar launches high temperature low GWP heat pump
New range of high temperature air-to-water heat pumps capable of producing hot water up to 70degC while still achieving high energy efficiencies
Formula for success: Sizing heat pumps in hybrid energy centres
Reducing the size of heat pumps in hybrid energy centres can cut carbon and capital costs dramatically – but what ratio of heat should they supply? Research by FairHeat’s Ellie Hiscock used hourly load modelling to come up with a rule of thumb for the optimal heat ratios for heat pumps and thermal storage with electric boilers
Beauty in standardisation: Travis Perkins’ digital plan to decarbonise housebuilding
Travis Perkins’ WholeHouse digital design platform allows housebuilders to deliver efficient, repeatable housing to the latest sustainability standards, and includes prefabricated heat pump systems. Alex Smith reports
Taking the waters: recovering heat from the Roman Baths
Heat from Bath’s hot springs is being used to warm surrounding buildings including the new Clore Learning Centre. Andy Pearson finds out how Buro Happold extracting heat from the mineral-rich waters of the Roman Baths
Solar thermal springing back into fashion
The growth in heat pump applications is another development in favour of solar thermal
Arriving on Platform G: Google’s new King’s Cross office
Google’s landmark ‘Platform G’ office development will be arriving in King’s Cross, London in 2024. Andy Pearson talks
to building services consultant Atelier Ten to find out how a BIM model was used to coordinate the highly innovative buildings services design along its 330-metre length
Switching to propane: reducing charge in a propane heat pump
Propane’s low GWP is making it an increasingly attractive alternative to refrigerants restricted by the F-gas Regulations. Tim Dwyer tracks the growth of propane and looks at the L150 initiative in Germany that is aiming to reduce the charge in a propane refrigerant circuit
