Ventilation is essential for health and comfort of building occupants. It is particularly required to diluteand/or remove pollutants emitted by occupants metabolism.
Prediction and Control of Temperature in Air-Conditioned Indoor Spaces Using Proper Orthogonal Decomposition | 2006 | English
A method for controlling the temperature of the occupancy zone in a room equipped with a fan coil ispresented. The heterogeneity of the air velocity field and the temperature distribution is considered.
This work lies within the concept of positive energy buildings.
Impact of Pump Control on Indoor Climate and Energy Efficiency of Hydronic Networks | 2006 | English
The use of variable speed pump allows to save energy. Therefore, the impact of these technologieson the heating system and thermal comfort in buildings is rarely highlighted.
The use of electricity in buildings constitutes around 16% of Singapore’s energy demand. To incorporate energy efficiency measures is one of the key mission to ensure that the economy is sustainable.
Measuring Air Change Rates using the PFT Technique in Residential Buildings in Northern Portugal | 2006 | English
Portugal has technical recommendations and standards regarding ventilation rates in naturalventilation systems.
Management Of The Time-Distribution Of The Needs For Indoor Air Renewal In Humidity Sensitive Ventilation | 2006 | English
Although unanimously acknowledged by the experts for its performances as regards energyeffectiveness and indoor air quality optimisation, humidity sensitive ventilation still too often suffersfrom a lack of knowledge inherent in its singularities.
Although the concept of ventilation has been around for several thousand years, the application of ventilation to overcome low productivity in warm to hot climates has been neglected over the last few decades.
Indoor Thermal Climate Criteria and the Effects on the Overall Environmental Performance of Air-Conditioning Systems | 2006 | English
The cooling loads of an office building vary with the desired indoor thermal climate.
Experimental determination of thermal characteristics of lightweight building element with dual ventilated cavities | 2006 | English
Available time for building construction is getting shorter, therefore the number of buildings which are built with lightweight building elements (LBE) is increasing.
Air leakages can cause a significant energy penalty, inability of the heating system, and failure of the ventilation system – especially in passive houses. However, they can be avoided if given serious consideration in the design phase.
Demand Controlled Ventilation as Efficient Means to Achieve Energy Savings in Tertiary Sector Buildings | 2006 | English
Demand-controlled ventilation (DCV) has largely been documented in the literature through fielddemonstration projects and computer simulation studies.
The passive cooling techniques such as night time cross ventilation is potentially an interesting strategy to provide substantial cooling energy savings in warm climates.
The potential for passive cooling of roof slabs incorporating an air cavity is important with respect tothermal comfort.
The purpose of this study is to determine how levels of ventilation rates and indoor air quality vary in elementary schools in southern Japan. This study is based on field monitoring carried out as intermittent monitoring from summer to winter.
A Survey on Workplace Occupant Satisfaction. A Study in Sixteen German Office Buildings | 2006 | English
This paper presents results of an evaluation of workplace occupant satisfaction in 16 state ofthe art office buildings of a variety of sizes and energy concepts in Germany.
Study on the Airflow Structure in Cross-Ventilated Rooms with the Full-Scale Model Experiment | 2006 | English
Cross ventilation is one of the most important techniques for maintaining a comfortable indoorenvironment in hot and mild seasons with less cooling energy.
In this study the COwZ model (COMIS with sub-zones) was modified to allow dynamic simulations ofindoor thermal conditions, humidity and pollutant transport and concentrations throughout wholebuildings.
CFD Modeling of Heat Convection in a Large Cross-section Earth-to-Air Heat Exchanger | 2006 | English
An Earth-to-Air Heat Exchanger (ETAHE) is a low energy cooling and heating technology for buildings.
