The active management of thermal flow within glazed structures has been a long standing issue for building owners, tenants and operators – in California, USA, it is estimated that 40% of a typical building’s cooling requirements are due to solar heat gain through windows. Passive solutions to solar heat gain issues exist using layers of insulation and films – however they serve only to block heat and cannot be managed to actively manage the flow of heat. PicoworX are in the process of optimising and further developing an active technology, incorporating the use of nanotechnology controlled by active low power electronics that can alter the conductivity of glass – enabling an intelligent Building Management System (BMS) to monitor interior temperature, adjusting the glass conductivity to allow heat into or out of the building as required. This technology can be used in conjunction with other glass technologies that adjust the levels of light transmission within the building, making truly intelligent buildings a reality – with adjustable control over thermal flow and light transmission. The PicoworX technology was developed in University College Dublin by Professor Dominic Zerulla and his colleagues in the Physics Department. Development work on the technology is ongoing as the PicowroX team engage with industry to ensure their requirements are exceeded.
