Variable flow rate summer air-conditioning systems with low energy consumption for small buildings | 2007 | English
In the present study the relation between the wind speed and the air temperature during the summer period over the greater area of Athens is examined.
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.
The effects of roof angle and width of adjacent buildings on wind-induced cooling ventilation of atrium spaces | 2007 | English
The wind-induced natural ventilation of atrium buildingswith two roof openings has been investigated using computational fluid dynamics (CFD) techniques.
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.
Air quality measured in a classroom served by roof mounted natural ventilation windcatchers | 2007 | English
This study examines air quality measured in two classroomsin a UK school, which uses two different forms of natural ventilation, over an eight month period.
Ventilation systems to minimize food odor spreading in high rise residentialbuildings | 2007 | English
A food odor spread is one of the air quality problems in high rise residential buildings in Korea. The food odor is mainly produced during the cooking of food. The food odor is generated in the limited spaces like in the kitchenand at a table.
Study of a new photocatalytic air cleaner applied to the management of the microbiologicalindoor air quality | 2007 | English
The objective of this research consists of studying the effectiveness of devices used in the microbiological purification of the air. This specifically involves the inactivationof biological aerosols in an air handling unit.
Experiences from the first German EPBD implementations: - Field tests for residentialand non-residential buildings - Certificates for well-known national and international buildings | 2007 | English
In preparation of the implementation of the Energy Performanceof Buildings Directive (EPBD) the responsibleGerman Ministry has undertaken several actions includingthe developmentof a new energy performance calculationprocedure for non-residential
Application of new design of wind tower configuration to existing building for passive cooling | 2007 | English
In hot and arid climates, evaporative cooling appears to have significant potential to provide thermal comfort and reduce the energy loads of summer season.
In situ measurement of window air tightness : stakes, feasibility, and first results | 2007 | English
In order to limit ventilation losses in low-energy buildings,balance ventilation systems with high-efficiency heat recovery units are often used.
Goal of the study was to investigate the relation betweenthe level of ventilation and the performance of school children in classroomsIn one school in two classrooms the same ventilation system was installed.
Feasibility study for renewable and low-energy applications in urban building sector | 2007 | English
Global warming and fossil energy sources depletion represent an emergency at Planet scale.
The exergy approach for the evaluation of heating and cooling technologies; first results comparing steady state and dynamic simulations | 2007 | English
Energy saving and emissions reduction are both affectedby the energy efficiency of the built environment and the matching between the quality of the energy carrierand the quality of the required energy.
The impact of building envelope design on thermal performance of office buildingsin Egypt | 2007 | English
This paper introduces research being carried out to support effective energy efficient design in Egypt. It is based on deriving results of multiple parametric simulationsof energy performance of office buildings in Cairo and Alexandria.
The purpose of this work is to study numerically the indoorenvironmental conditions in an office.
Presently the assessment of the thermal behaviour and the energy efficiency of naturally ventilated double skin facades (DSF) is only possible by using complex simulationtools, which allow inter-connections between fluid dynamics, energy balances
The energy performance of glazed office buildings with double skin facades - BESTFACADE | 2007 | English
Many modern office buildings have highly glazed facades.Their energy efficiency and indoor climate is, however, being questioned.
This document aims to present the progress and the outcome of the research on double skin façades that is being carried out within the European ‘BESTFACADE’ project.
The Energy Performance of Buildings Directive (EPBD) obligates EU member states to develop a reliablemethodology capable of calculating and certifying the energy performance (EP) of their building stock.
