Natural ventilation specialist, Breathing Buildings, is championing the benefits of PCM (phase change materials) in the construction of a more sustainable built environment, at this year’s EcoBuild exhibition (ExCel London on 5-7 March 2013).

Dr Shaun Fitzgerald, Managing Director of Breathing Buildings, will be presenting the case for greater use of PCM with John Spicer, Technical Sales Manager of Armstrong.

Backed by over 150 years of successful operations, Armstrong is a global leader in providing acoustic, design and environmental ceiling and wall system solutions for interior environments. Based in Lancaster, Pennsylvania, Armstrong operates 32 plants in eight countries and has approximately 8,500 employees worldwide. In 2012, Armstrong's consolidated net sales from continuing operations totalled approximately $2.6 billion.

The presentation by the two companies will take place on Thursday 7 March and forms part of the Ecobuild Product Search CPD (continual professional development) programme hosted in the CPD zone, located in the North Hall (N2020). Breathing Buildings and Armstrong’s presentation is titled ‘Case study: energy saving solutions using phase change materials’, which is part of the session ‘Making the most of low and zero carbon energy technologies in buildings’. This session will run from 2:15pm-3:45pm in Seminar Room 11.

Phase change materials convert from solid to liquid and liquid to solid to absorb or release large amounts of latent heat at a relatively constant temperature.

As Dr Fitzgerald says: “When the internal room temperature increases, the PCM core changes from a solid to liquid state and in doing so absorbs and stores latent heat. As the internal room temperature cools the PCM core changes again, but this time from liquid to a solid state, thus releasing the stored latent heat.”

“By removing the peaks and troughs in temperature change significant reductions can be achieved in the energy demand of HVAC systems.”
