A new concept of zero carbon classroom construction, incorporating the thermally broken Thermomass concrete sandwich wall panel system, has been developed in conjunction with one of the Thermomass precast concrete suppliers.
Whilst concrete school designs are becoming recognised as an excellent way to build robust and durable constructions, this is the first time that the Thermomass system has been used in a standard zero carbon classroom system.
The Thermomass panels provide a U-value below 0.15 W/m2K: the same as those used in PassivHaus construction. But in this case, they form part of the overall package that enables a classroom to hit the zero carbon targets now being set for modern school construction.
The Thermomass classroom system is virtually a kit of parts that can be finished externally in a range of finishes including real brick (depending on planning constraints) and simply painted internally.
These classroom blocks are delivered from start to completion in just six weeks: totally fitted out, including all toilets, taps, plumbing and electrics.
A structure for a demonstration reception classroom of 66m2 was erected in just one working day.
Visitors to the demonstration show classroom have particularly commented on the comfortable environment within the space. This is due to the high thermal mass of the building, which irons out the peaks and troughs of usual daytime temperatures to provide an almost steady internal temperature state.
The fine control of the internal temperature, by the use of the passive thermal mass effect, has the additional benefit of significantly reducing energy costs; just using top-up and requiring no air conditioning. It is this effect that significantly adds to the zero carbon credentials of the classroom buildings.
Thermomass concrete sandwich panels have revised a tradition originated by the Victorians: building schools that are substantial, robust and durable, acoustically and thermally comfortable, not suspect to fire damage or vandalism, and yet aesthetically attractive with a high level of functionality.
These very high standard schools will be fit for future generations to inherit and use, and yet they can be provided within the limits of the latest government cost targets for education buildings.
