“…Establishing the actual thermal losses of the typical Cyprus residence, and identifying the dominant mechanisms and elements that contribute the most to the total residential thermal energy demand can become a useful tool in the hands of policy-makers, engineers as well as academia involved in the building sector in general. Even though previous studies have been conducted in modelling the Cypriot residence and its energy consumption (Florides et al 2000) and also identifying the energy behaviour of the residential buildings stock in Cyprus (Panayiotou et al 2010), this is actually the first time that in situ measurements were performed in such a large scale in order to check the accuracy of such theoretical predictions. Theoretical predictions are based on methodologies developed mainly in the USA and northern European countries, thus, their direct implementation cannot be fully relied on due to the difference in climatic conditions, building architecture and materials used for construction.…”

The present work aims to establish the thermal characteristics and actual thermal behaviour of typical residential houses in Cyprus under real weather conditions. For this purpose, a wireless web-based monitoring system has been deployed covering 44 different houses, geographically spread all over Cyprus. Construction materials varied amongst each house, resulting in a theoretical U-value range of 0.467-1.389 W/m 2 K. Calibrated temperature sensors were installed and measurements were conducted at 30-min intervals for each individual house. The indoor air temperature of each house, the outside (ambient) air temperature, and the internal and external wall surface temperatures have continuously been monitored for a period of 15 months. Processing the above-mentioned data has led to the establishment of the mean indoor air temperature of the typical Cypriot residence and calculation of the U-value for each individual wall, facing north, south, east and west, including the roof, comprising the building envelope. Variations of the calculated U-value of up to 25% for each wall orientation were observed, even though construction materials of each wall remain the same. Furthermore, deviations of up to 30% from the theoretical U-value calculation were also observed.

“…The typical annual load profile definition was also based on the statistical analysis conducted by Panayiotou et al [1]. In this statistical analysis a sample of 500 houses along with analytical data given by the Electricity Authority of Cyprus were used and it was concluded that there are two peaks observed on the consumption of electricity in the domestic sector annually; one in summer, which is the highest, and one in winter.…”

“…The characteristics of the baseline scenario concern the structure, location, occupancy and energy systems installed in the house examined. The data used to define these characteristics were based on the statistical analysis conducted by Panayiotou et al [1] which concerned the characteristics and the energy behavior of the residential building stock of Cyprus in view of Directive 2002/91/EC.…”

Abstract:In this work the design and simulation of two stand-alone renewable energy sources (RES) based systems for application in a household in Cyprus is presented. More specifically, the household is located in Nicosia and is used as the residence of a typical Cypriot family for which a baseline scenario of energy consumption is specified in order to define the annual load profile of the house. The first system is based on photovoltaic (PV) modules for the generation of electricity by harvesting the very high solar potential of Cyprus while the second one is a hybrid system combining PVs with a domestic wind turbine in order to take advantage of the wind potential especially during winter. Since both systems are stand alone the energy produced is stored in a battery bank. The software used for the modeling and simulation processes is TRNSYS. A comparison of the two systems in terms of both technical and economical aspects is presented in this study where it is concluded that the wind potential of the specific location of the house, which generally applies on the entire island, cannot substitute and compete in any way with the very high solar potential.

“…Indeed, to achieve a reduction in energy consumption and an implementation of energy efficient technologies, on-going research in the field is needed [33]. According to above stated matters, this study uses the reveal of the energy demand in existing legislation from ELIH-Med (Energy Efficiency of Low Income Housing in the Mediterranean) and Era-co-build (European co-operative organisation) survey data, conducted in 2012 by the EU, which is the most recent data set available at the time of undertaking the research for this study.…”

This research project is undertaken in the Turkish Republic of Northern Cyprus (T.R.N.C.). The objective of the research is to investigate the occupants' behaviour and role in the refurbishment activity by exploring how and why occupants decide to change building systems and how to understand why and how occupants consider using energy-efficient measurements. The housing estates are chosen from 16 different projects in four different regions of the T.R.N.C. that include urban and suburban areas. The study is conducted through semi-structured interviews to identify occupants' behaviour as it is associated with refurbishment activity. This paper presents the results of semi-structured interviews with 70 homeowners in a selected group of 16 housing estates in four different parts of the T.R.N.C. Alongside the construction process and its impact on the environment, the results point out the need for control mechanisms in the housing sector to promote and support the adoption of retrofit strategies and to minimise non-controlled refurbishment activities. The results demonstrate that European Union Energy Efficiency directives need not only inform households about technological improvements that can be installed in their residential properties, but should also strongly encourage and incentivise them to use them efficiently. Furthermore, the occupants' energy consumption behaviour and the applicable policy interventions will make the difference between implementing policy which in fact delivers on its aims for energy efficiency and sustainability.
