The increase of the ambient air temperatures in urban areas during the past few decades, due to the heat island phenomenon and the warming of the lower atmosphere, has strong impact on the energy profile of buildings, the comfort conditions, the a

Carbon dioxide has been already recognized as a potential tracer gas towards estimation of the mean air exchange rates (ACH) of a room or building.
D. Kraniotis, T. Aurlien, T.K. Thiis
Cooling energy savings in a building with the roof coated by high reflectance paint are examined. It is difficult to recognize the cooling energy savings by using the data observed every hour.
C. Yamada, H. Takebayashi, E. Ishii and K. Miki
The EPBD directive (91/2002/EU) paved the way for the European Union member states to develop and apply a holistic approach on the building’s energy performance.

Nowadays, important efforts are made to reduce the residential building energy consumption. In this context, a growing interest for heat recovery ventilation has been observed during the last decades.
S. Gendebien, E. Georges, L. Prieels and V. Lemort
Toward the appropriate selection of urban heat island measures technology in the street canyon, the introduction effects of the technologies in the typical street canyon are analysed by the model calculation.
H. Takebayashi, Y. Kimura and S. Kyogoku
Heat recovery ventilation became an unavoidable element of a passive or nearly zero energy building in Northern and Central Europe countries.
F. Flourentzou, S. Pantet
With the continuous improvement of the energy performance of buildings, ventilation plays a crucial role in the control of pollutants from indoor sources and related comfort and health effects.

As a consequence of the energy and environmental issues, it is necessary to reduce the energy consumption of buildings. So, the air tightness of building envelopes is being improved and the air change rate due to infiltration is decreasing.
A. Ginestet, D. Pugnet and L. Mouradian
Roofs are the envelope component more severely hit by solar radiation in summer (1470 kWh/m2 on average in Italy), hence one may expect that using cool materials on the finishing layer of a roof should provide a significant reduction in the heat f

The PerFluorocarbon Tracer (PFT) method is a low-cost method commonly used for measuring air exchange in buildings.
M. Sherman, I. Walker and M. Lunden
This paper describes part of the research that is being done on the prediction of the performance of light pipes and the ways to optimize their design, in order to house artificial lighting, able to supplement daylight in a space.

There is a growing consensus that the climate is changing faster than at any time in the past millennium. This is likely to have major effects upon many aspects of the built environment.
J. Holmes, T. Taylor, J. Counsell
The materials that are used in outdoor spaces are of prime importance as they modulate the air temperature of the lowest layers of the urban canopy layer, they are central to the energy balance of the surface and they form the energy exchanges tha

In order to improve the quality of ventilation systems, assessments are widely used. In this paper, 3 main assessment levels are distinguished based on the number of ventilation systems to be assessed and the assessment objective.

The raise of sustainability in the urban design is a key-factor for addressing the challenges in response to climate change, resource availability, environmental degradation and energy consumption.

Highly reflective building envelope materials are widely identified as an effective design option to limit the peak surface temperatures of roofs in summer conditions, thus mitigating the urban microclimates and the energy demand for cooling.

French authorities have launched an extensive thermal renovation program aiming at retrofitting 4M dwellings over 10 years, with priority given to the most energy consuming ones.

Few studies focus on commercial low-rise buildings which are often characterized by low-cost constructions materials and weak energy performances. For these large volumes, the heat transfers with the roof and the ground are prevalent.
R. Lapisa, E. Bozonnet, M. O. Abadie, P. Salagnac, R. Perrin
Effective conservation of historic buildings subject to monumental restrictions is realized through a re-use for modern functions.
