Internal airflow sensitivity in a naturally ventilated atrium subject to variation in external wind conditions | 2007 | English
The use of windows is a key adaptive opportunity in naturally ventilated buildings especially in summer when the building is likely to be free-running.
The primary aim of the EP label project was to develop a methodology for energy benchmarking and certification of buildings, based on Operational Ratings, to address the EPBD Article 7.3 requirement for Public Buildings over 1,000 m to display an
Methodologies to bring innovative environmental technology R&D results into the market | 2007 | English
It has been widely recognised that too few projects initiatedunder both national as well as EU funded research projects find their way to commercial exploitation.
The paper deals with applicability of passive and low energy cooling technologies in the Czech Republic.In the paper there are presented two recent studies, where computer simulation helps to design properly the passive and low energy cooling for
Estimation on the effectiveness of the crossventilation as a passive cooling method for houses | 2007 | English
The integration of research outputs on the cross ventilation is tried in order to quantify the reduction of cooling energy, by raising the stepwise questions and by reviewingexisting knowledge useful to find solutions.
The effect of natural ventilation on the indoor air quality in classroom of the elementaryschool without heating equipments during winter season | 2007 | English
Field survey on indoor air quality was conducted during winter season, in an elementary school at Kagoshima city.
Variable flow rate summer air-conditioning systems with low energy consumption for small buildings | 2007 | English
The energy performances of a summer air-conditioningsystem with variable airflow destined fora sole air-conditioned open-space environment which hosts a call-centre are presented.
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.
Solar shading and ventilation patterns: to what extent are they accurate to comfort expectations? | 2007 | English
In temperate continental climates, the reduction of the solar radiation influence in summer season, over the comfort conditions of internal spaces, can only be achieved by natural means in two ways: one possibility is through occupants adjustments
In order to overcome the increasing energy demand in buildings and related environmental problems, new efficientenergy technologies and new integrated building concepts, like solar passive and mixed-weighted thermalmass buildings, are being develo
Floor cooling and air-cooling, the effects on thermal comfort of different cooling systems | 2007 | English
One of the research areas of the Energy research Centreof the Netherlands (ECN) concerns the built environment.Several facilities to conduct research activitiesare at ECNs disposal.
In Korea, all residential buildings adopt floor- heating systems for indoor thermal comfort. And the ratio of multi-family houses exceeds 50%.
