The European research project “EULEB – European high quality Low Energy Buildings” intends to provide information about good examples of energy efficient buildings in use, in order to reduce prejudices and lack of knowledge of many key actors of the build

The discussions around the implementation of the Energy Performance of Buildings Directive (EPBD) [1] – not only in national legislation but also in real practice – have revealed open questions and caused different interpretations. This paper deals with o

Near-extreme solar irradiance, ambient dry-bulb and wet-bulb temperatures are fundamentaldata for determining the peak building cooling load. Design solar irradiance has beenseparately and independently selected by both ASHRAE and CIBSE. This may result in overestimatedcooling loads, and in turn over-sized air-conditioning systems. Hence, a statisticmethod based on probability theory and heat transfer principles was developed for rationalselection of the three coincident design weather data used for calculating peak cooling loadsin a building with thermal lag less than one hour.

A growing interest has been addressed to multi-energy systems in buildings that involve theintegration of different energy sources to cover the thermal and electrical loads of thebuilding. A modelling approach to multi-energy systems in buildings based on the concept ofhybrid energy hub is presented. The model has been customised to be used in the conceptphase of the building design, either as a system simulation tool or as a system designoptimization tool.

The use of bioclimatic solutions in architecture has been for a long time in Europe aconsolidated procedure, especially developed in northern countries. In the last years, in Italytoo, It has been followed through a good policy to increase the construction of buildingsequipped with solar energy harnessing system; many architectural competitions expressly askfor passive solar architectonic solutions.

Novi Sad is capital administrative center of the Province Vojvodina, one of two towns with active oil refinery crossroad of transit traffic artery and until recently great industrial town! In this paper are presented data of imission for basic pollutant matters in the air of the town, microclimate and health condition of children and adult population according to permanent reports of health services for preschool, schoolchildren and physician in primary health care (general population) for the period 2002-2005.

The installation of thermostatic valves and cost allocators represents the main modernizationmeasure of the heating installation. In this study we determined theoretically andexperimentally their effects upon the energy savings. Their adaptive behavior to the dynamicclimatic conditions leads to 15% energy savings. Further on, the people reduce the indoortemperature in order to reduce the price of the energy. This effect represents another 9%,leading to a total of 24% energy savings. The north apartments need 15% more thermalenergy than the south oriented apartments.

Various means of improving the energy efficiency of commercial buildings while preservingand/or improving their internal environmental quality have been extensively studied. In therecent past, the Gas Technology Institute (GTI), produced several of such studies orientedexclusively to identifying the benefits of applying various energy efficiency technologies todifferent types of commercial installations in the U.S.A. and also in Europe. Independently,these involved technologies for desiccant dehumidification and/or systems of combinedheating, cooling, and power generation, (CHP).

The focus on the needs and drives for adaptation of the building automatically leads tochanging needs and demands of the occupants of the building. Building should really takecare of its occupants and show adaptable behaviour and reaction to the changing outdoorenvironment during the day. Design for adaptability should start with the occupants needs forcomfort and indoor air quality. These are partly influences by the changing environmentalforces as wind and sun.

Close to Zermatt (Switzerland) the new Monte Rosa mountain cabin is going to be built in2008 at 2810 metres above sea level. This hut is designed to accommodate 120 mountaineers.Furthermore, it is going to mark a milestone in high alpine building presenting an attractive,unconventional architecture combined with both a surpassing comfort and a high degree ofenergy autarky of over 90%.Of course several measures have to be taken to achieve such a high degree of autarky whilealways keeping a limited budget in mind.
