“…In response to the increased urban (air and land surface) temperatures and the strong relationship between high urban air temperatures and adverse heat-related health outcomes (e.g., thermal discomfort, mortality, and heat-related illness) [7][8][9][10][11][12], urban planners and decision makers are recognizing the growing need to create more attractive, thermally comfortable, and sustainable cities, especially as urban populations expand and climatic variability and extremes increase [13][14][15]. Results of specific building adaptation studies for Athens, Greece showed that this is possible when appropriate and energy-efficient building technologies are used [16].…”

Mitigation plans to counteract overheating in urban areas need to be based on a thorough knowledge of the state of the thermal environment, most importantly on the presence of areas which consistently demonstrate higher or lower urban land surface temperatures (hereinafter referred to as "hot spots" or "cold spots", respectively). The main objective of this research study is to develop a methodological approach for the recognition of thermal "hot spots" and "cold spots" in urban areas during summer; this is accomplished with (a) the combined use of high and medium spatial resolution satellite data (Landsat 8 and Terra-MODIS, respectively); (b) the downscaling of the Terra-MODIS satellite data so as to acquire spatial resolution similar to the Landsat one and at the same time take advantage of the high revisit time as compared to the respective one of Landsat (16 days); and (c) the application of a statistical clustering technique to recognize "hot spots" and "cold spots". The methodological approach was applied as a case study for the urban area of Athens, Greece for a summer period. Results demonstrated the capacity of the methodological approach to recognize "hot spots" and "cold spots", revealed a strong relationship between land use and "hot spots" and "cold spots", and showed that the average land surface temperature (LST) difference between the "hot spots" and "cold spots" can reach 9.1 • K.

“…The agreement in the calculation of whole building heating requirement between the two methods indicates that the two methods can be safely used together for the purposes of this study. Further to this the predicted heating requirement is found to be within the range presented by a relevant study for this climatic region 1 [49] Equation Table 2)  Sola olle to s surface area…”

This paper examines the inextricable link between the performance of solar combi-systems coupled with under-floor radiant heating and the architectural design of buildings where such systems may be used. It focuses on the impact of building fabric, area and oo s layout on both the s ste s pe fo a e a d thermal comfort. The building integration of the distribution pipework is sensitively examined through an experimental analysis of a case study; a residence in South Europe, using dynamic thermal simulation and numerical modeling. It is found that pipe losses -regarded both as energy wastage and heat gains to the space -can be significant but also controlled if the pipe network is carefully planned. The results show that collector loop losses can be comparable to tank losses for most of the year or even higher in some months, and that the management of the collector loop piping length can be more effective in controlling these losses than improving the pipes insulation. The analysis further shows that there are times when distribution losses have the potential to cause noticeable local overheating e.g. long piping length or piping route passing through narrow spaces like corridors and lobbies.

“…According to [26,27] the building sector is projected to encounter significant changes in reference to its energy consumption profile, through the implementation of regulatory measures, the growth of the energy service sector, the employment of demand side management measures, as well as by the technological advances and market penetration of energy efficient systems and technologies. In particular, the introduction of new building codes enabling the construction of near to zero emissions buildings in 2020 together with the rehabilitation and energy renovation of older buildings will lead to a significant reduction of the energy consumption of the buildings sector, considering not only domestic, but also commercial and public buildings.…”
