An innovative thermal insulation material for building envelopes.

Résumé

CO2 is a substantial greenhouse gas; emissions of CO2 are the greatest contribution to global warming, and buildings are large emitters of CO2. Therefore, energy-saving technology, especially to reduce electricity consumption for air-conditioned (or solely heated) buildings, has been widely investigated. The properties of the building envelope have a strong influence on the thermal performance of buildings (in addition to airtightness of the building envelope), in particular the U-value of their walls/roofs. This paper aims to summarise current developments of state of the art vacuum insulation panels (VIPs), which provide a quantum leap forward in thermal insulation, offering exciting opportunities for both new and retrofitted buildings. Thermal modelling for VIPs and overall effective U-values of walls constructed by VIPs have been carried out. Use of VIPs not only reduces the internal area of buildings but also exhibits excellent performance to meet the requirements of building regulations, as well as offering a great potential to reduce energy consumption for heating, ventilation and air-conditioning systems. The most important consideration in using VIPs is to eliminate cold bridging at the edges and joints between panels in addition to achieving sufficient longevity.
