Implementing the recommendations of an air-conditioning inspection carried out by Efficient Air last year has improved the energy performance of the Eland House headquarters of the CLG by 12.6%. The energy saving is 662 MWh a year, valued at £41 000. CO2 emissions are calculated to have been reduced by 250 t.

Not only will a new VRF air-conditioning system in the University of Sheffield’s S10health fitness centre achieve significant energy savings compared to the previous system but it will also meet increased cooling demands.

Chilled ceilings and beams can often provide effective comfort cooling when refurbishing existing buildings — as John Staunton explains.

Existing 27-year-old boilers at Ashville College in Harrogate have been replaced with Buderus condensing boilers to meet the heating requirements of the entire senior-school building. The two GB312 boilers have an output of 200 kW and replace two 300 kW cast-iron boilers.

A failing Victorian heating system in a church at Penwortham near Preston has been replaced with a modern boiler-based system using two Remeha Quinta 65 boilers.

By eliminating the cycling of boilers to compensate for standing heat losses, Sabien Technology’s M2G controller can reduce energy consumption and carbon emissions by 10 to 25%, depending on site conditions and applications.

To meet the particular requirements of refurbishment projects, Advanced Ergonomic Technologies has launched an all-air VAV underfloor air-conditioning systems

When refurbishing, new boilers can provide a reliable means of reducing carbon emissions and savings on energy costs says Bob Walsh.
