SCOTTISH PRIMARY SCHOOL OPTS FOR OXYGEN
As part of South Lanarkshire Council’s primary schools modernisation programme, James Aiton Primary School underwent a £7 million rebuild. The rebuilt facility comprises seven classrooms, assembly and dining halls, a library and ICT room. In order to reduce carbon emissions, the building was fited with a biomass boiler alongside a heating system which, the council insisted, would not only heat, but also provide fresh, clean air throughout the classrooms. The council opted for a Jaga Oxygen ventilation system with Maxi LST radiators. “The solution we recommended,” says Jaga’s Jason Boshell, “provided a safe, robust radiator, while the Oxygen system would guarantee the amount of ventilation required.” Jaga has also announced
the launch of the second in its series of e-guides. Called ‘Heating and Ventilation in Schools’, it’s available as a free download from the company’s website (
www.jaga.co.uk) and details considerations for specifiers when choosing heating and ventilation solutions in schools, as well as advice as to the most suitable options available. Managing director Phil
Marris says: “Our second e-guide targets communities involved in the specification of heating and ventilating systems in educational institutions by tailoring each approach to suit the intended outcome.”
Education sector welcomes RHI changes
Launched in 2011, the government’s non-domestic RHI scheme saw some initial success. Some feel, however, that the scheme was dominated by biomass technology as organisations took advantage of the good tariffs available for heat produced by biomass systems. Part of the reason for this, it is said, was the omission of air to water heat pumps from the original eligibility criteria. Now, though, the Department of
Energy and Climate Change has taken action. Air to water heat pumps have been added to the scheme as part of a number of improvements, including changes to some tariff rates. Under the changes, air to water heat pumps are included with a tariff of 2.5p/kWh and the tariffs for renewable heat generated by ground source heat pumps increased with split tariffs of 8.7p/kWh for the first 1,314 hours of operation and 2.6p/kWh for any operation over 1,314 hours. Solar thermal technology also benefits from an increased tariff, up from 9.2p/kWh to 10p/kWh. These changes to the non-domestic

RHI scheme have been welcomed by building service professionals and by schools and universities looking for an answer to rising heating bills. It also represents another step towards achieving the government’s target that 15 per cent of all energy will come from renewable sources by 2020.
Discrete Heat skirts around the issue

One of Cambridge University’s oldest purpose-built student residences has undergone refurbishment. Cripps Court houses 200 student tenants and heating the large building with its many individual rooms in a way which was both cost- and energy-efficient was a priority. Architects specified Discrete Heat’s Thermaskirt heating system, which was installed by contractors Munro Building Services. The combination of the skirting board and radiator in one unit allowed for reduced installation times due to the saving of over 2.4 km
of pipework that would be necessary if using a traditional radiator and skirting system. Health and safety queries were addressed by the low-profile nature of ThermaSkirt and its secure fixing to the wall. These features are designed in order to make it resilient to the exuberant student environment with which it has to cope. “ThermaSkirt a quick and simple-to-install retrofit that enabled us to navigate around the contours of the rooms while freeing up wall space that would otherwise be taken up by radiators,” says Munro’s Andy Maltby.
