In this paper, indirect evaporative cooling in an air cooler has been modeled. This model has been obtained from the governing equations of heat and mass transfer in primaryand secondary air and water flows. Factors affectingon evaporative cooling performance such as mass flow rates, geometry and flow configuration has been investigated. Results show that cooling efficiency considerablydepends on mass flow rates ratios of primary and secondary air flows and spacing between plates of wet and dry passages.

The European Energy Performance of Buildings Directive(EPBD) encourages the use of technologies in buildings that can potentially improve their energy performance.Double ventilated faades can often have a positive contribution to this objective and their effect has to be quantified during the calculation of the overallenergy performance of the buildings. The updated EN ISO 13790 Standard is part of the new set of CEN Standards that have to be delivered to support the EPBD requirement for a general framework for the methodologyof calculation of the total energy performance of buildings.

The Millennium Development Goals, approved by 189 countries in September 2000, and the Johannesburg Plan of Implementation, adopted in 2002 by the World Summiton Sustainable Development (WSSD), emphasize the urgent need for greater commitment to reduce inequalitiesand assist in the development of poor countries.The 21 Mediterranean countries and the European Communitydecided in line with the WSSD process, to prepare a Mediterranean Strategy for Sustainable Development (MSSD), and requested the Mediterranean Commission on Sustainable Development (MCSD) of the MediterraneanAction Plan (MAP) t

The current discussion about energy saving measures in the built environment and the forthcoming new European guidelines “Energy efficiency in Buildings” motivated an aluminium facade company (Hydro Buildings Systems) to set up an interdisciplinary team f

In order to reduce the energy cost for heating and improvethe internal conditions during the summer period in greenhouses, they have been investigated different solutions including passive cooling techniques and hybridsystems. Such kind of solutions is the minimization of the ventilation losses through cracks and openings, the increase of the thermal mass of the greenhouses and the use of ground heat exchangers.

This paper describes an educational and experimental tool developed under LabVIEW environment at LASH/DGCB (France) laboratory of ENTPE. The objective of this tool is to make students sensitive with HVAC equipments, measurements, heat recovery, and regulation techniques in order to expand and test heating, cooling and ventilation control strategies. A large room of the Buildings Sciences Laboratory (LASH) is equipped with balanced mechanical ventilation and a global control/data acquisition system.

Double Skin Facades (DSF) have been a recently developed technology to improve the thermal performance of conventional façades of buildings which use large glazed areas. However, there has been a lack of test information on the behaviour and performance o

This paper outlines the findings of a research project undertaken as part of the design for St. Anthony’s School, a primary school in the town of Gudalur situated in tropical southern India. The objective of this paper is to demonstrate a design approach

The sensation of comfort in buildings depends on externaland internal variables: the well-known PMV method relates the expected temperature with the physiological behavior of the human body. Some models have discussedthe relevance of adaptation factors, in order to explainthe higher expected good temperature of users living in warm climates. The same PMV method has been modified for these climatic situations.

Highly glazed buildings are often considered to be airy, light and transparent with more access to daylight. Their performance, however, regarding to energy use and thermal comfort issues is often questioned. Passive solar systems such as Double Skin Faades are likely to improve the overall building performance if integratedproperly. This article deals with energy and indoor climate simulations of double skin office buildings in Sweden using a dynamic energy simulation tool.
