Passive natural cooling techniques for wooden buildings in warm climate: case study | 2007 | English
The consequences of the global climate change are perceptible even in Italy, where in the last 15 years the mean temperature values increased of 0.4 °C in the northern part of the country and of 0.7°C in the southern one.
Dynamic Analysis Methods and Modelling. Application to Energy Performance Assessment | 2007 | English
The application of system identification techniques to the energy performance assessment of buildings and building components requires a high level of knowledgeof physical and mathematical processes.
After the terrible consequence of the Iraq –Iran war and recently USA attack over Iraq the urban green covering disappeared from large areas of the city, beside the extension of the building over the green areas.
Heating and cooling buildings needs too much energy consumption; thing that is becoming rare and more expensive.Internal thermal comfort is essentially evaluatedaccording to bioclimatic conditions and energy consumption.So the aim of the study is
Since 1999, several widely used building energy efficiencystandards, including ASHRAE 90.1, ASHRAE 90.2, the International Energy Conservation Code, and Californias Title 24 have adopted cool roof credits or requirements.
The potential application of residential solar thermal cooling in the UK and the role of thermal energy storage technologies. | 2007 | English
As the UK Building Regulations demand better insulatedand more airtight new buildings, a potential cooling requirement is emerging in new build dwellings in the UK, leading to an increase in the market for domestic air conditioning systems in this
Throughout architectural history, local buildings have used great in providing the most comfortable internal conditions possible within the exigencies and constraintsof local climate.In Iraqis climates, accelerating airflow through induces evapora
The evaluation of thermal comfort conditions in simplified urban spaces: the COMFA+ model | 2007 | English
One of the main elements to consider in urban space design is the modification of the microclimate in order to improve the thermal comfort conditions of people livingin urban spaces.Sometimes it is very important to design very specific conditions
Optimal indoor air quality, thermal comfort and energy conservation in schools is of great importance. A new development in indoor climate control in schools is hydronicradiant heating and cooling (HRHC).
The objective of this paper is to evaluate the usefulness and the accuracy of an artificial neural network (ANN) as a prediction tool of the wind pressure coefficient (Cp). The ANN is applied to predict the Cp for rectangularbuildings.
Due to the lack of national building regulation regardingthe energy requirements of Directive 2002/91/EC (EPBD) in Greece, Southern countries (Italy, Spain and Portugal) have been selected as index reference because of the similar climatic conditi
Case study of the weighed factors of stack effect and the reduction alternatives in tall complex building | 2007 | English
The purpose of this case study is to analyze stack effect problems and to develop the method minimizing stack effect in the tall complex building in the winter season. The main problems in tall complex building occur in high-rise elevators.
Ventilation of Dutch schools presently insufficient; an integral approach to improvedesign | 2007 | English
Indoor Air Quality and thermal climate in schools is problematicin many countries. The status quo in the Netherlandsis presented (e.g. average CO2 levels in schools, problems with ventilation).
Residential active cooling toward snowy cold region in japan andhuman temperaturesensitivity for passive and low energycooling | 2007 | English
Results of survey on residential active cooling as the diffusion rate of air conditioner in five principal cities of in Japan, and those associated “human temperature sensitivity” for passive and low energy cooling are described.
Knowledge extraction from energy certification of buildings – Results from the ENPER-EXIST project | 2007 | English
The ENPER-EXIST project was initiated and coordinated by Centre Scientifique et Technique du Bâtiment (CSTB) within the framework of the Intelligent Energy Europe (IEE) programme.
For the assessment of air to air heat recovery systems in ventilation systems, efficiency seems to be the major evaluation parameter, although other parameters such as pressure drop, frost behavior and power consumption of fans can play an importa
To predict ventilation and related air flow parameters, a lot of calculation techniques could be utilized; however the main difficulties concern ease of use and the providingof input data.
Investigating and analyzing the thermal behavior of the “green roof system” installedin two buildings in Athens, Greece | 2007 | English
The present paper deals with the experimental analysis and monitoring of the energy and environmental performanceof a green roof system installed in two residences,in the region of Athens, Greece.
Window opening behavior and resultant thermal and air quality environment in elementary school classrooms | 2007 | English
A study was performed in 6 elementary schools in Japan,and measurements were made on temperature in classrooms and corridors, outdoor temperature, CO2 concentration and closing or opening of windows and doors.
