Market assessment of passive downdraught evaporative cooling in non-domestic buildings in southern europe. | 2002 | English
The purpose of the work is the determination of unsteady variation of the moisture content in the walls. The mathematical model is based on humidity transport equations in porous media.
Performance of heating systems from the point of energy consumption and thermal comfort in dwellings | 2002 | English
The quality of indoor environment in dwellings is provided by physical properties of building constructions and by operation of HVAC-systems.
Performance evaluation of rotary dessicant wheels using a simplified psychometirc model as design tool | 2002 | English
In the present communication, a psychometric model has been presented to evaluate the performance of rotary desiccant wheels based on different kind of desiccants e.g. silica gel and LiCl.
The main goal of the present study was to determine thermal comfort parameters for dwellers of low-cost houses for a given set of indoor environmental conditions.
Experimental evaluation of the performance of a prototype hybrid solar photovoltaic-thermal (PV/T) air collector for the integration in sloped roof | 2002 | English
Detailed simulation studies on the design and development of PV/T systems are being carried out at the Politecnico di Milano, for their possible integration with a sloped roof.
Assessment of natural ventilation potential of a region using degree-hours estimated on global weather data | 2002 | English
The applicability of natural ventilation depends strongly on climate. The potential of natural ventilation represents a measure of the feasibility of natural ventilation in a specific climate.
Moisture transport across imperfect hydraulic contact interface - A parametric study | 2002 | English
Material properties, water vapor permeability, sorption/suction isotherm and moisture diffusivity, are prerequisite for application of all hygrothermal models.
In this work a methodology for indoor environmental quality assessment was applied, based on thermal, visual, and acoustic comfort indices and on their analysis and spatial representation.Object of the study was one secondary school classroom of t
To evaluate innovations and efficiency as regards air-conditioning, it is necessary to know for how long and in which conditions the equipment functions, an indication related with the COOLING LOAD and which is their effectiveness - EER - on avera
Moisture transport in building materials with imperfect hydraulic contact interfaces | 2002 | English
Based on the experimental results and predictions of a numerical model, the effects of uncertainty in estimation of imperfection of the interface on moisture transport were studied in the present study.
This paper describes a modular facade system, which supplies the room behind with the necessary amounts of heat, light and fresh air.
Effect of thermal mass on natural ventilation in a single-zone building with two openings | 2002 | English
This paper considers an ideal naturally ventilated building model that allows a theoretical study of the effect of thermal mass associating with the non-linear coupling between the airflow rate and the indoor air temperature.The thermal mass numbe
The use of hypochlorite for water disinfection is source of chloramines production, which are transferred to the atmosphere.Nitrogen trichloride (NCl3) is the main component, which is a major cause of respiratory and ocular problems for swimmers a
In the introduction of the paper are reasons presented, which cause local thermal discomfort. Currently the reasons of asymmetric thermal radiation are not clearly explained.
In order to save energy for building cooling during hot days in regions with cool nights, air circulation throughout the interior of the building has been envisaged as a means to lower the temperature of the building structural mass.
The main objective of our study was to know more about indoor air quality in offices building over a long period. Our study has been carried out in one building located downtown Lyon (France).
An energy balance over an urban area and over a rural one, reveals that the first case is always more complex than the last one. The urban context is able to change all the energy transferences mainly due to its own layout.
This paper describes the results of a collaboration study between ENTPE-LASH and LEPTAB within the framework of the IEA Annex 35 “Hybrid Ventilation in New and Retrofitted Buildings”.
In this work, experiments were carried out to estimate deposition rate of 5µm particles powder in large cylindrical straight ducts for different diameters. Two types of ducts were compared: rigid ducts and flexible ducts.
