Накратко на български

Екологичните леки гранули (eco-LWG) се разработват за съхранение на топлинна енергия чрез материали, които променят състоянието си при топене и замръзване. Те помагат за подобряване на изолацията на сградите, за да се намали консумацията на енергия и въглеродните емисии.

Eco-lightweight granules for energy efficient applications

Buildings in Europe are responsible for more than 40% of total energy consumption and 25% of carbon emissions. This is mainly due to the high number of old housing stock with very poor insulation systems. Such buildings require a huge energy demand for heating and cooling needs, which increases their carbon footprint. Moreover, by 2050 it is predicted that the number of households worldwide will grow by 67% and service sector buildings by 195%. Developing innovative energy-efficient and low/zero-carbon materials are key areas in which the building sector can meet carbon reduction targets. A possible solution is to use phase change materials (PCMs). These can control temperature fluctuations and increase thermal mass in buildings thanks to their ability to store and release thermal energy during phase change processes (melting and freezing). However, PCMs need to be encapsulated before they can be incorporated into the built environment, to avoid leaking and incompatibilities with the construction matrix which contains them. There are several paths to incorporate PCMs. One existing method soaks commercial lightweight aggregates (LWA) in PCM. Therefore, the amount of PCM that the LWAs can host is limited by the latter’s absorption capacity, which is low. The overall objective of this EU funded project was to deliver new energy efficient construction materials that can contribute to achieving the 2020 target of nearly zero-energy and highly material efficient buildings, which is an essential target to achieve sustainable growth in the EU. To achieve this, we engineered eco-lightweight granules (eco-LWG) to help mitigate the aforementioned problems.

Цел на проекта

Buildings in Europe are responsible for more than 40% of total energy consumption and 25% of carbon emissions, mainly due to the high number of old housing stock with very poor insulation systems. This research will develop new energy efficient materials by engineering eco-lightweight granules (eco-LWG) to mitigate these problems. The eco-LWG will have high strength and high water absorption, ~100 wt.%, and be made from widely available waste materials: recycled mixed coloured glass, clay and limestone. The eco-LWG will be used to contain phase change materials (PCM), which use chemical bonds to store and release heat, allowing control of temperature fluctuations. The high level of porosity in the eco-LWG will allow them to absorb and retain much higher levels of PCM than has previously been possible using existing lightweight aggregates. Both the eco-LWG and the PCM loaded eco-LWG will be optimised by statistical design methodology and they will be used to develop new energy efficient construction products. Two impregnation methods will be compared to introduce the PCM into the eco-LWG: vacuum sorption to achieve maximum PCM uptake and short term immersion to partially fill the connected porosity. These will produce innovative lightweight and high heat-storage materials. Incorporating PCM loaded granules in mortars and other construction materials will result in reduced energy requirements to heat and cool buildings and improve indoor living conditions. The eco-LWG developed in this research will also be used in green roofs to provide water retention capacity and slow nutrient release. Green roofs can reduce the energy requirements of buildings and urban pollution. This multidisciplinary innovative research will deliver new energy efficient construction materials that can contribute to achieving the 2020 target of nearly zero-energy and highly material efficient buildings, which is an essential target to achieve sustainable growth in the EU.
