Results of Monitoring a Naturally Ventilated and Passively Cooled Office Building in Frankfurt A.M., Germany | 2006 | English
Important oversizing factors are observed for room air-conditioners leading to important energy wastes and costly summer peak demands for utilities.
Analytic models and static approaches as the case of Fanger, Deval, Sherman, Gagge, and Stolwijkmodels cannot completely predict indoor thermal comfort.
Ventilation is essential for health and comfort of building occupants. It is particularly required to diluteand/or remove pollutants emitted by occupants metabolism.
This work lies within the concept of positive energy buildings.
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.
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.
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.
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.
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.
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.
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.
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 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.
The potential for passive cooling of roof slabs incorporating an air cavity is important with respect tothermal comfort.
Consequences of Increasing Insulation on the Annual Energy Consumption of Air-Conditioned Office Buildings | 2006 | English
The aim of this work is to study the influence of global heat transfer coefficient (Utot en W/m2.K) of the opaque walls (walls and roofs) and of the glazed walls (bays) on the annual consumption of heating, cooling and overall consumption energy.
Influence of Air Leakage in Building’s Walls on Heat Transmission Loss through its Envelope | 2006 | English
The energy consumption of a building is evaluated by neglecting the heat loss which can occur when the air passes through the envelope.
