EPBD

The opening keynote will present an overview of the current status and future opportunities for smart buildings in Europe, in the context of the transition to more sustainable use of energy. In 2017 EASME mapped the activities of projects working on smart buildings and the extent of EU support given under the Horizon 2020 framework programme. The results were presented at the conference Sustainable Places 2017 at Teeside University (UK) and published the same year in a special issue of the peer reviewed journal Buildings.

This paper uses two case studies to illustrate the process of building design with due regard to sustainable construction and how the recent changes in legislations affect the way buildings are designed in the UK. Two real case studies cover housing and commercial office sectors. These case studies indicate that a performance based design approach exploiting building simulation offers a building with an improved indoor comfort, lower carbon emissions and added value to the client. Finally, this paper offers some insight into future developments of the UK legislations.

Paper is focused on description of Czech national methodology and tool for energy performance calculation according to EPBD (Energy performance building directive 91/2002). Energy performance calculation is expressed by total annual energy consumption, including heating, cooling, ventilation, auxiliary and other energy required for building operation. There is a simplified multizone model, loaded by typical day for each month in hourly time step. Climate data are synthetic data for 4 climate zones according to standards, used for building physics calculation.

The updated ISO 13790 Standard is part of the new set of CEN Standards that supports the European Energy Performance of Buildings Directive (EPBD) requirement for a general framework for calculation of the energy consumption of buildings. The Standard sets out procedures for space heating and cooling energy calculations, allowing the use of three different methods: a simplified monthly quasi-steady state method, a simple-hourly method and detailed simulation. This paper examines the implications of allowing different methods to be used for assessing the energy usage.

It is only comparatively recently, since the development of mechanical ventilation and refrigeration, that it has become possible to completely control the air quality and thermal environment inside buildings, irrespective of outdoor conditions. However, such control is an energy intensive process that requires reliable energy supply. Concerns about future security of conventional supply, combined with the impact of fossil fuel emissions on global warming, has resulted in renewed emphasis on building energy efficiency.

At present 95% of energy consumption for heating, domestic hot water, air conditioning, lighting andventilation in Europe are related to buildings built before 1980.

The existing buildings stock in European countries accounts for over 40% of final energy consumption in the European Union (EU) member states, of which residential use represents 63% of total energy consumption in the buildings sector. Consequently, an increase of building energy performance can constitute an important instrument in the efforts to alleviate the EU energy import dependency and comply with the Kyoto Protocol to reduce carbon dioxide emissions.

The European Union’s (EU) Energy Performance of Buildings Directive (EPBD) aims to increase the energy performance (EP) of buildings by requiring EU Member States to develop an EP calculation methodology and to certify the EP of their buildings. Dynamic s
