Improving the Microclimate in a Dense Urban Area Using Experimental and Theoretical Techniques – The Case of Marousi, Athens | 2012 | English
The aim of this paper is to illustrate the impact of urban wind environments when assessing the availability of natural ventilation.
A Modelling Study of Segmentation of Naturally Ventilated Tall Office Buildings in a Hot and Humid Climate | 2012 | English
The prevailing paradigm in indoor environment control of office buildings often excludes natural ventilation, due to the fact that its dynamic nature may not be compatible with the close control of mechanical conditioning systems.
Field Study Assessment of the Performance of Displacement Air Distribution in a Canadian School during the Heating Season | 2012 | English
Stratified ventilation systems use a fundamentally different approach to supply heated or cooled air through a building than the ‘fully mixed and dilution’ ventilation systems found in the majority of non-residential buildings.
Evaluation of Indoor Air Quality in Classrooms Equipped with Cross-Flow Ventilation | 2012 | English
In this work the evaluation of indoor air quality in a classroom equipped with cross-flow ventilation is presented.
The accurate prediction of particle deposition in ventilation ducts is an important step in estimating the exposure risk of building occupants to particulate matter.
The air pumping effect of a fire plume, proposed years ago, to give a higher air intake rate through vertical openings in a compartment fire is further investigated in this paper.
As compared to mixing ventilation systems, the personalized ventilation system (PV) can help to create a healthy and comfortable working environment with a simultaneous reduction of energy consumption.
Exploiting a Hybrid Environmental Design Strategy in the Continental Climate of Beijing | 2012 | English
The built environment in China is required to achieve a 50% reduction in carbon emissions by 2020 against the 1980 design standard.
With the rapid development of urbanization, the economy and number of vehicles, the urban climate has worsened in recent years, causing serious urban problems including urban heat islands, air pollution and infectious disease transmission. Ventila
To study the thermal effects on airflow in a street canyon under real heating conditions (due to diurnal solar radiation), a one-way static approach combining an urban canopy model and CFD is proposed in this paper.
An Optimization Method of Sensor Layout to Improve Source Identification Accuracy in the Indoor Environment | 2012 | English
This study presents an optimization method of sensor layout to improve identification accuracy of indoor contaminant sources.
Experimental Investigation of Air Distribution in the Occupied Zones of an Air Curtain Ventilated Enclosure | 2012 | English
This paper focuses on the performance of a new air curtain ventilation system.
An Experimental Investigation of Natural Ventilators for Improving Indoor Air Quality | 2012 | English
Based on the theoretical and experimental studies of natural ventilation, the performance of natural ventilators has been analysed. Four types of natural window ventilators and three types of wall ventilators were studied.
Comparison of Wind-Driven Natural Ventilation for Different Windows in a Room with a Single Opening | 2012 | English
In order to get more effective natural ventilation into a room with a single sided opening or large depth, two new window types have been developed in the laboratory. These are based on three new patent developments.
Assessing Adaptive Thermal Comfort Using Artificial Neural Networks in Naturally-Ventilated Buildings | 2012 | English
This paper presents a method for predicting occupants’ indoor thermal sensation in naturally-ventilated environments, based on real thermal sensation samples, using a GA-BP neural network model.
Performance of Counter Flow Heat Recovery Ventilation Systems in Dwellings Considering the Influence of Uncertainties | 2012 | English
Both critical and optimistic claims have been made regarding the performance of heat recovery ventilation systems (HRVS) in dwellings. Such arguments are raised partly because two key aspects are not fully clarified, i.e.
A Static Pressure Reset Control System with a New Type of Flow Damper for Use in Low Pressure Ventilation Systems | 2012 | English
The control strategy for mechanical ventilation systems has significant impact on the performance of the system, in terms of energy consumption and correct air distribution.
A Wind Channel Passive Ventilation System for Deep-Plan, High-Rise Residential Buildings | 2012 | English
In a world where energy conservation in buildings is an important target, natural ventilation is an important field in which carbon footprint reductions can be achieved.
Optimization of a Lobed Perforated Panel Diffuser - A Numerical Study of Orifice Arrangement | 2012 | English
Heating Ventilating and Air Conditioning (HVAC) systems are primarily designed for ensuring good indoor air quality and thermal comfort. However, building energy requirements tend to put demand on reducing air change rates.
