“…The incorporation of mandatory energy performance requirements during the design or renovation phase of a building has been a key driver for the uptake of energy efficiency measures in the Cypriot building stock. Focus however could be drawn on increasing the ambition of NZEB levels [3] and strengthening compliance with the minimum energy performance requirements during major renovations. In addition, the role of Energy Performance Certificates as an information tool could be strengthened by establishing independent control systems, creating a publicly available EPC database and putting penalties for noncompliance.…”

“…In 2015, the residential and services sectors collectively represented the second largest energy consuming sector in Cyprus (after transport) at 317 ktoe and 214 ktoe, respectively. In the bottom-up analysis carried out for the Cyprus residential building stock as part of the TABULA-EPISCOPE project, it was found that the final energy demand for heating and cooling of typical houses could be reduced by up to 84% through ambitions energy renovations [3]. Indeed, statistical data published by the Cyprus Energy Agency (Buildings' Typology Cyprus, Cyprus Energy Agency, May 2012 (available on TABULA-EPISCOPE website)) show that less than 10% of the residential building stock are equipped with wall, roof, or basement insulation, while over 50% of the buildings have no thermal insulation.…”

Financing the Renovation of the Cypriot Building Stock: An Assessment of the Energy Saving Potential of Different Policy Scenarios Based on the Invert/EE-Lab Model

Despite various government policies promoting energy efficiency in buildings over the last 15 years, Cyprus is still associated with a large untapped energy efficiency potential in this sector. The impact of different policy scenarios on future energy needs of the building sector in Cyprus is explored by first reviewing the current status of the building stock in Cyprus and existing national landscape of energy efficiency policies. Various new policies are then proposed to complement the existing framework and help exploit further the potential. Using the Invert/EE-Lab model, three policy scenarios extending to 2050 are assessed with the aim to estimate the energy efficiency potential of the Cypriot building sector and identify policy solutions to harness this potential. The energy consumed for heating, cooling, hot water, and lighting in the entire Cypriot building stock is expected to drop by up to 16% in 2050 compared to the baseline scenario. Under the most ambitious scenario, nearly 60% of the building stock in 2050 will be energy efficient, consuming less than half of the energy used by the average building stock in 2012. Taking into account the modelling results, recommendations on how to improve the financial landscape in buildings until 2050 are presented.

“…The existing literature on bioclimatic design primarily considers case studies of certain regional characteristics, with the results being applicable mainly to areas with similar attributes. For example, in a refurbishment study it was estimated that adding movable shading devices to an existing single family house of the Mediterranean region was the optimal solution for energy conservation and economic viability [12]. A similar study in a Cyprus dwelling also suggested external bioclimatic interventions (horizontal overhangs) within a range of measures that could be applied to refurbish an existing dwelling into a nearly zero energy building (nZEB), with a payback period of less than 1 year [13].…”

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.

“…Some of them pointed out the need to define this concept more precisely. In the research field, there are case studies of new constructed nZEB dwellings [17], or the renovation of a single family house to achieve the nZEB level in the Mediterranean region [18,19]. Lindkvist et al [20] presented an extension of the nZEB concept to the near Zero-Energy Neighbourhood; the authors concluded that, although this constitutes an area with opportunities for intervention, the knowledge of nZEB renovations is not being transferred and financial and social barriers should be addressed.…”

Perspectives on Near ZEB Renovation Projects for Residential Buildings: The Spanish Case

EU regulations are gradually moving towards policies that reduce energy consumption and its environmental impact. To reach this goal, improving energy efficiency in residential buildings is a key action line. The European Parliament adopted the Near Zero-Energy Building (nZEB) as the energy efficiency paradigm through Directive 2010/31/EU, but a common technical and legislative framework for energy renovations is yet to be established. In this paper, the nZEB definition by COHERENO was adopted to evaluate several energy renovation packages in a given building, which is also representative of the Spanish building stock. Global costs are calculated for all of them following EPBD prescriptions. Two economic scenarios are analysed: with entirely private funding and with the current public financial incentives, respectively. The results show the divergence between optimum solutions in terms of costs and of minimum CO 2 footprint and maximum energy saving. Moreover, in the absence of enough incentives, some inefficient renovations could achieve a global cost close to the optimal cost. The optimum solution both in terms of energy performance and global costs was carried out and described.
