Paris A. Fokaides is a visiting Lecturer of experimental and computational building physics in the Department of Civil Engineering of Frederick University, Cyprus. Dr. Fokaides’ research is primarily concerned with experimental thermofluid mechanics, with a particular focus on the field of buildings’ energy efficiency. He is the author and/or co-author of more than 30 publications in peer-reviewed journals and conference proceedings as well as 4 book chapters. Dr. Fokaides is the coinventor of a European patent regarding a novel gas turbine fuel injection system. Currently Paris offers the courses of building physics, renewable energy sources and experimental fluid mechanics.

Kalogirou: „Application of infrared thermography for the determination of the overall heat transfer coefficient (U-Value) in building envelopes“, Journal of Applied Energy (2011), DOI:10.1016/j.apenergy.2011.05.014. Infrared (IR) thermography constitutes a reliable measurement method for the determination of spatially resolved surface temperature distributions. IR thermography may be used for several research problems, applications, and measurement environments with a variety of physical arrangements. In this work the results of the determination of the overall heat transfer coefficient (U-Value) with the use of IR thermography for building envelopes are presented. The obtained U-Values are validated by means of measurements performed with the use of a thermohygrometer for two seasons (summer and winter), as well as with the notional results provided by the relevant EN standard. Issues related to the applicability of the method due to the nonsteady heat transfer phenomena observed at building shells are also discussed. A more precise validation of the proposed technique was also performed with the use of heat flux meters.

Kalogirou: „Comparison between measured and calculated energy performance for dwellings in a summer dominant environment“, Journal of Energy and Buildings (2011), DOI:10.1016/j.enbuild.2011.08.005. The objective of this study is to present a comparison between the measured and the calculated energy performance of dwellings. For this purpose, the energy consumption of ten dwellings is measured for one year. The added value of this work is that it is performed in a summer dominant environment. The energy needs of the same dwellings are also calculated by means of the methodology based on European Standards described in the CEN/TR 15615:2008 technical report. According to the findings of this study, a large gap exists between the calculated and the measured energy consumption of the examined dwellings. In order to evaluate the reasons for this deviation, a detailed analysis of the heating and cooling loads of the dwellings is performed. The intermittent heating of the building is found to be simulated accurately by the employed methodology, whereas the comparison between the calculated and the measured cooling loads reveals a large deviation of about 150%.

  • P.A. Fokaides: „Towards zero energy buildings (ZEB): The role of environmental technologies.“, Book chapter in: Green and Ecological Technologies for Urban Planning: Creating Smart Cities, Ed. Ö. Ercoskun (2011), DOI:10.4018/978-1-61350-453-6.ch006. In 2009, European Union (EU) member states forged a long awaited compromise on the recast buildings directive, agreeing that all new buildings would have to comply with high energy performance standards by the end of 2020. The recast Energy Performance of Buildings Directive, which was finally announced in May 2010, requires the public sector to take the lead by owning buildings with “nearly zero” energy consumption standards by the end of 2018, which is two years in advance of the private sector. The objective of this chapter is to discuss both the range of potential consequences to European cities resulting from widespread implementation of zero energy buildings (ZEBs) and the relevant environmental technologies in accordance with the national goals set by the EU Member States. As EU member states are moving ahead with their targets and strategies for ZEBs, this chapter presents the most possible scenarios for the implementation of the EU recast buildings directive regarding ZEBs by 2020. A detailed review regarding the existing EU member states’ definitions and policies on low energy buildings and ZEBs, and the current status of RES technologies for ZEBs is also presented. Finally, some first thoughts are provided regarding the minimisation of energy consumption in the building sector and the green city goal, as energy is considered to be one of the most important chapters when evaluating a green community. The next step for the integration of green buildings would be the adoption of 3 principles resulting from ZEB analyses and descriptions in existing green building models.

  • Fokaides, M.C. Phocas, N. Charalambous: „Aiming at sustainability through multilayering for the Cyprus News Agency building proposal“, Proceedings of COST 25 Final Conference, 2011, Austria. The present paper analyses the design proposal for the new building of the Cyprus News Agency. In terms of sustainability, of major importance was the interactive development of the spatial configuration and the façade elements design according to the natural ventilation of the interior and the external sun-protection systems applied. In the latter case the glass façade of the newsroom of the building is sun-protected through a double mesh layer of steel elements. Hori-zontally the layers form a filigree “curtain” with openings that are defined parametrically as to the visual interconnections from the inside to the outside and vice versa. The environmental anal-ysis of the space refers to the natural lighting and the thermal comfort of the users. The design example clarifies the methodology of interdisciplinary integrated design, whereas architecture, morphology, construction and bioclimatic design are interrelated from an early design stage to achieve innovation in materials and systems.
