For outsiders, a national energy performance (EP) requirement level is quite a black box.

Comparing Energy Performance requirement levels among Member States of Europe (EU ASIEPI project) | 2009 | English
This paper analyzes some important aspects toward changing energy paradigma in urban area.To that aim it is important to act synergically on three sides of the energy system:- Demand side: by reducing energy demand;- Supply side: by optimizing gen
Experimentation of Hybrid Ventilation in Carnegie Mellon University's Intelligent Workplace, Pittsburgh, PA | 2009 | English
The Center for Building Performances and Diagnostics of Carnegie Mellon University is experimenting with Hybrid Ventilation in Pittsburgh, Pennsylvania, USA, to evaluate the potential energy savings of this technique in a region where there are ma
Ventilation in schools is very important as it has a direct relation to health and performance of pupils.The status quo of school ventilation in the Netherlands is presented: lots of problems and insufficientsituations were found.
Since the 2002/91/CE EPBD was published, all European countries should making efforts in harmonizing local standards, imposing the assessment of building energy and environmental impact through a common certification procedure.
Use of compact balanced single-room ventilation units with heat recovery in existing dwellings | 2009 | English
Renovation of existing buildings, in order to reduce energy consumption, represents a big market inEurope.
The emission from materials is an important source of degradation of our indoor air quality.
Analysis of Dispersion and Prediction of Infection Possibility according to Airborne Viral Contaminants: Tracer gas simulation | 2009 | English
The aim of this study is to analyse the physical characteristics of airborne virus, consider thepossibility of using coupled analysis model and tracer gas for analysing virus diffusion in buildingspace and, based on reports of how the infection sp
Studying influence of airtightness on heating loads by coupling simplified simulation and multizone airflow model | 2009 | English
In order to respond to global warming and natural resources depletion challenges, industrials from the building sector need to propose an adequate offer. Energy simulation tools can support this process.
Thermal bridges increase the building energy demand for heating and cooling. For well insulatedenvelopes and buildings with increased energy efficiency, the influence of thermal bridging on theenergy consumption is of major importance.
The Swedish Code of Statutes SFS 1991:1273, Compulsory Ventilation Checks to be Continued | 2009 | English
Since 1991 has Sweden regulations on compulsory inspection of ventilation systems (OVK). Thereasons to issue these regulations were many studies on poor indoor climate and health problems for building occupants.
This study examines the potential for using passive ventilation systems to meet ASHRAE 62.2requirements as a step in the process for optimizing hybrid ventilation systems.
The French regulation on residential building ventilation relies on an overall and continuous airrenewal. The fresh air should enter the building through the habitable rooms while the polluted air isextracted in the service rooms.
Differences might arise between the design and the real load of ventilation systems during operation.Consequently, the fresh air demand usually varies over a wide range.
Experimental Results and Experience from the Retrofit of an Office Building with Passive Cooling - REB Remscheid | 2009 | English
The office building belonging to the Remscheider Entsorgungsbetriebe REB (Waste DisposalUnit in Remscheid), which was constructed in 1968, was thoroughly renovated in 2004.
Air Distribution Effectiveness for Residential Mechanical Ventilation: Simulation and Comparison of Normalized Exposures | 2009 | English
Even when providing the same nominal rate of outdoor air (OA), different ventilation systems distribute air in different ways, affecting the occupants differently depending on the dwelling, on source disposition and strength, on occupants behavior
The Energy Policy Act of 2005 (EPAct05) requires that federal building energy-efficiency performance standards be revised.
The paper is devoted to the analysis of possibility for construction of low energy buildings withenvelopes controlled for minimization of energy consumption by air conditioning systems.
In most Dutch classrooms draught results in insufficient ventilation and poor air quality during the heating season, adversely affecting the well being and performance of pupils.
The high influence of ventilation on the energy efficiency in buildings containing large-volume spaces - Example-building: The German parliament building "Reichstag" in Berlin | 2009 | English
The influence of ventilation on the energy performance of a building is generally considered to be quite high. It rises clearly, when a building contains large-volume spaces.
