Safeguarding affordable and energy-efficient medical services has emerged as a crucial necessity to sustain national healthcare systems, especially in view of the current pandemic. While a set of national standards and guidelines aim to set minimum energy requirements for the building facilities, more insight into the healthcare sector’s energy consumption in Cyprus is deemed necessary, since it is the 4th most energy-demanding sector per square meter in this country. This is the first extended research on energy consumption in healthcare facilities across the different climatic zones of Cyprus and the types of fuel favoured in each zone, which marks the novelty of this work. The findings of the study highlight that the coastal and inland climatic zones are the most energy-challenging regions, with more than 60% of the final energy needs covered by electricity. On the contrary, in the mountainous region, approximately 80% of the final energy needs are covered by oil and attributed mainly to heating purposes. The average national primary energy consumption of healthcare facilities was found to be 497 kWh/m2 in air-conditioned spaces. Therefore, this study highlights that the mean primary energy consumption per building surface is approximately 4 times higher than the national threshold for nZEBs; compelling critical consideration of intervention for their energy enhancement. Moreover, healthcare facilities in mountainous regions in Cyprus are heavily reliant on conventional fuel; an unreliable and highly polluting energy option. The work demonstrates the prominent challenge and high potential for energy retrofit of the examined facilities and their upgrading to nZEB-Hospitals, towards the endeavour to a climate-neutral energy transition.

The rapid trends of urbanization have catastrophic consequences on the ecology of our cities. The large amounts of energy consumption and the reckless exploitation of natural resources is leading to increased emissions of ozone depleting gases and carbon dioxide emissions, which are polluting our planet and enhancing the effects of global warming. This paper will present the bioclimatic approach in achieving a smart urban isle as a basic unit for the development of sustainable cities of the EU ERANET project “Smart bioclimatic low-carbon urban areas as innovative energy isles in the sustainable city” (SUI). It will outline the project and demonstrate the approach of achieving bioclimatic urban isles through the Cyprus case study. The main aim of the SUI project is to develop sustainable cities through balancing locally the energy systems. Thus, the project aspires to move forward with the urban energy and CO2 reduction. The study will focus on the bioclimatic approach, which is one of the three cornerstone procedures (Bioclimatic design, Smart Grids and Management Platform) on which the project is based. It will exemplify how the various aspects of the bioclimatic design and the utilization of the beneficial aspects of the surrounding environment are exploited and applied on defined urban isles, as a basic unit of the city.

This paper examines the thermal comfort conditions during summer and winter in an existing office building in an urban context. It investigates and correlates the results obtained from a questionnaire survey, conducted during summer and winter, with the two comfort models - for mechanically ventilated spaces and non-mechanically ventilated ones - in order to determine the most appropriate one for the energy performance evaluation of the office buildings in the coastal Mediterranean region. The study is carried out within the framework of the Urban Europe project Smart Urban Isle and it specifically refers to the Cyprus case study. The project considers the bioclimatic design of the buildings and of their urban environment, as well as potential energy management systems, in order to define and evaluate urban isles as a basic unit of energy measurement for Smart Cities. The Cyprus case study focuses on the impact of the thermal comfort Standards on the energy performance evaluation of the buildings and it promotes the sustainable and energy efficient design by selecting the most appropriate Standard to assess the thermal comfort for occupants.
