GEOGREEN, “Waste geopolymeric binder-based natural vegetated panels for energy-efficient building green roofs and facades”, is a R&D Project funded by FCT, Foundation for Science and Technology. It is being carried on at CMADE – Centre of Materials and Building Technologies of University of Beira Interior, located at Faculty of Engineering with collaboration of Superior School of Agronomy of Polytechnic Institute of Castelo Branco (IPCB-ESA).
In development since 2011 until 2014, GEOGREEN project will carry on an interdisciplinary original study for the development of green roof and facades. Originality of this proposal resides in the fact that research intends to develop an pre-fabricated panel, incorporating vegetation, as part of a modular building system, that can be easily adapted to new buildings and retrofitting, being as well, easy to replace and maintained in normal functioning. The panel will be studied by using non-conventional waste-based materials (waste geopolymeric binder-based), combining physical and mechanical properties, as low density, porosity, water retention, mechanical strength, durability and fire resistance.
A brief description of each research activity is presented, as follows:
- Plant growing – Studying use of indigenous or endemic vegetation for a specific climate having with large thermal amplitude (very hot summer- very cold winter).
- Panel production – Studying and production of various compositions for panel structure using non-conventional waste-based materials (waste geopolymeric binder-based ), combining low density, porosity, strength, durability and fire resistance.
- System design – Designing of an original pre-grown vegetated panel modular-base d system suitable for both new building and retrofitting. Studying different combinations of layers composition: growing vegetation, drainage, water management and protection media, as a single composite panel were insulation properties in summer and heat storage in winter will be enhanced.
- Real conditions testing – Carrying on real climate experimental measurements, numerical modeling, and thermal and energy performance, for different solutions, using an infrastructure developed and constructed with this project.
- Practical implications – Proposing practical recommendations for the pre-fabrication of the developed system and its integration in modern urban areas and building retrofitting.
Project achievements will also contribute to sustainable development, particularly in terms of energy savings, waste recycling and use of low CO2 binders, as well for biodiversity, urban modernization and building retrofitting.
