This paper presents the basic parameters and energy flows of an aquifer thermal energy storage (ATES) systemcombined with reversible water/water heat pumps used for heating and cooling the new hospital Klina (Antwerp Belgium). The system is one of the first ATES projects in Belgium, and its operation is monitoredwith the aid of a DAQ system. The energy flows, primary energy consumption and CO2 emission reductionwere calculated based on DAQ loggings of the first 3 years of systems operation.
Energy-efficiency benchmarking can be used to monitorchanges in overall efficiency of buildings. Benchmarkingmodels, based on energy-efficiency indicators are valuable tools for both public and private stakeholdersbecause they allow an improvement in the building energy management . For the last decade, some governmentshave used these tools to define their building regulations(M. Santamouris, 2005, W. Chung 2005). This paper tries to goes further, integrating a benchmarking and a modelling process, in the same energy efficiency analysis.
The buildings sector accounts for 40% of the energy requirements in Europe, which is more than by industryor transport. That is a lot and it is too much! Buildingstherefore have a major part to play in meeting the emissions reductions targets! And buildings of the futureshould therefore be designed in mutual cooperation in the design teams, i.e. between architects, developers,clients, engineers, etc. from day one of the design phase. This paper presents an EU supported project commenced in January 2007 looking especially on the processes of integrated energy design - IED.
In the last decades researches have indicated an extremelyhigh energy consumption of the building sector. Analysing the amount of consumed energy, it is showed that almost the 70% are expended for the heating and cooling loads of the building. Therefore, it is of great interest to exhaust the possibilities to reduce the thermallosses through the buildings shell.
Earth heat exchange (EHX) through buried horizontal air ducts (EHXair-hor) can be an effective passive/ibryde system to reduce heating and cooling loads in temperate climate zones. This paper shows the results of the authorsmost recent testing and design experience on the field. Conclusions are drawn in relation to the necessity of further monitoring and testing on more complex and variegated EHXair-hor systems.
Microclimate condition in an environment is influenced by the local environment condition. Urban morphology,especially building, pavement and greenery are the main factors. The ambient temperature in a built area located nearby a large park can be reduced with the average of 1.3oC as compared with no park built environment.In other studies also show that area of urban elements (building, greenery and pavement) determines the temperature of a built environment.In the other study, it is found that urban heat island exists in National University of Singapore (NUS).
Ecology in Architecture Design (EAD) is a project with the main aim of developing a blended (face to face lecturesplus online activities) learning course about how to integrate ecology in the architectural design, both at the level of a single building and of territory. EAD started in July 2004 as a project founded by the Swiss University Conference within the Swiss Virtual Campus(SVC), the national program studying the introductionof information and communication technologies in universities and universities of applied sciences.
Every time with major frequency grows the necessity of energy efficient buildings, adapted to their environment, which consume and contaminate as least as possible.In this study it has been analyzed and evaluated the thermal conditioning of two blocks of flats, a renovation one and a new one, taking advantage of the bioclimatic technologies and using renewable sources of energy.
The building sector is at present responsible for more than 40 % of the EU energy consumption. There are technologies under development, which could substantiallyimprove (up to 30 %) the energy performance of buildings, reducing the conventional energy demand in new and existing buildings and substantially contributingto reduce energy intensity, through combined measures of rational use of energy and integrationof renewable energy technologies.
