TL;DR: In this article, the authors analyzed the influence of envelope thermal insulation, age and condition of heating system, on the heating energy consumption and the resulting environmental impact of buildings in Europe.

TL;DR: The proposed Hellenic residential building typology is presented for the first time along with an assessment of various ECMs that are used for an estimate of the energy performance of building stock in Greece in an effort to meet the 9% indicative national energy savings target by 2016.

TL;DR: In this article, the major methodologies reported in literature were applied to 20-year hourly measurements of weather data from Athens, covering the period 1977 to 1996, and seventeen Test Reference Years (TRYs) were produced in total.

TL;DR: In this article, a total of 349 residential building audits were performed in seven European countries to collect data on the degradation of building elements (architectural and installations) at different states of deterioration.

TL;DR: In this paper, the authors present an overview of the database and its available tools, and the main results from a case study on Hellenic buildings that reveals relevant characteristics, focusing on the buildings' energy performance, thermal envelope characteristics and the exploitation of solar thermal energy.

TL;DR: In this article, the authors provide a systematic approach to proper selection and identification of the best retrofit options for existing buildings and provide a better understanding of how to effectively conduct a building retrofit to promote energy conservation and sustainability.

TL;DR: In this paper, a review of emerging simulation methods and implementation workflows for bottom-up urban building energy models (UBEM) is presented, as well as an outlook for future developments.

TL;DR: In this article, the authors presented an overview of the EU residential building stock and focused on the Hellenic buildings, and the methodology used to determine the priorities for energy conservation measures (ECMs) in Hellenic residential buildings to reduce the environmental impact from CO 2 emissions, through the implementation of a realistic and effective national action plan.

TL;DR: In this paper, a discrete model-based predictive control methodology is applied, consisting of three major components: the predictive models, implemented by radial basis function neural networks identified by means of a multi-objective genetic algorithm; the cost function that will be optimised to minimise energy consumption and maintain thermal comfort; and the optimisation method, a discrete branch and bound approach.

TL;DR: In this paper, a methodology for the identification of reference buildings, according to the IEE-TABULA project (2009-12) aimed at creating a harmonised structure for “European Building Typologies”, is presented.
