The Group of Building Environmental Research (GRBES), operates under the frame of the Section of Applied Physics, Department of Physics of the University of Athens. It carries out specific research and development programs in the fields of environmental quality of the built environment and environmental materials. In parallel, it offers education and training to under- and post-graduate students, and prepares educational material and books on the field of energy and environment. The Group was established after 1991. It employs 19 researchers and carries out specific research under contracts from National and International Institutions.

The Group works on the following research topics within the corresponding laboratories:

The Laboratory of Energy audits and energy efficient design of buildings, specialises in energy and environmental assessments of the built environment and studies to improve the energy and environmental performance of buildings. It has all the necessary equipment to support experimental and theoretical studies integrated in a modern mobile energy bus (infrared cameras, luminance cameras, tracer gas, equipment to measure in situ U values, thermal and visual comfort, all climatic parameters etc.). The Group has carried out more than one thousand energy audits and studies aiming to improve the energy efficiency of buildings in Greece and elsewhere. In parallel, the lab has developed materials that present thermochromic properties for the outdoor environment and materials that have extremely high reflectivity and appropriate emmissivity using nanotechnology procedures and tools. Experimental facilities involve advanced spectrophotometers and other sophisticated equipment to carry out ageing tests and measure the emissivity of materials.

The Laboratory of Ventilation and Indoor Air Quality involves all the necessary equipment to carry out specific ventilation and indoor air quality measurements. It combines multiple and single tracer gas equipment with an air chromatographer, an advanced indoor pollutants measurement equipment, air flow visualisation equipment, and equipment to measure the air speed and flow in indoor and outdoor environments. The lab has extensive experience in natural ventilation experiments. In parallel, the Group is equipped with a blower door facility to perform research and development work related to air infiltration and transfer of pollutants between the ambient and indoor environment and a modern GCMS facility for the qualitative and quantitative analysis of indoor pollutants.

The Group has coordinated the following International Research and development programs:

The most recent publications by the Group include, among many others:

Buildings, Energy and the Environment, University Studio Press, Thessaloniki, 2008

The scientific work carried out by NKUA fits in perfectly with the objectives of INIVE. INIVE membership facilitates efficient collaboration and information exchange among its members, while at the same time bringing complementarity to existing knowledge and skills. NKUA is a very active partner and participates in most of the activities of INIVE.
