Experimental determination of thermal characteristics of lightweight building element with dual ventilated cavities | 2006 | English
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.
Monitoring and Data Analysis of two Low Energy Office Buildings with a Thermo-Active Building System (TABS) | 2006 | English
A promising approach to reduce the primary energy demand of office-buildings without violatingthermal comfort is passive cooling by thermo-active building systems (TABS).
Quality Assurance of Solar Ventilated Facade and Mixing Chamber of the Moravian Metropolitan Library | 2006 | English
The objective of this paper is to present long time monitoring and post occupancy evaluation of theMoravian Metropolitan Library with the ventilated solar faade used for space heating and with mixing chamber for cooling with the forced ventilation
Being the largest energy consumer, building sector represents a major stake for the actualenvironmental concerns.
Application of Different Dynamic Analysis Approaches to Estimate the U and G Values of Building Components | 2006 | English
Dynamic analysis is very useful to obtain thermal properties of building components.
Energy-Environmental Efficiency in the Integrated Design of a School Building in Imola, Italy | 2006 | English
The Municipality of Imola is strongly committed to environmental friendly and energy consciouspolicies both at urban planning level and public building design.
Responsive Building Elements (RBE), as defined in International Energy Agency - Annex 44,are building construction components which are actively used for transfer and storage ofheat, light, water and air.
Exergy Analysis as an Assessment Tool of Heat Recovery of Dwelling Ventilation Systems | 2006 | English
In cold and moderate climates, improvements in building shell insulation and air-tightness imply a shiftin heating loads from transmission and infiltration towards ventilation.
In this paper, a model for predicting whole building heat and moisture transfer was presented. Both heat and moisture transfer in the building envelope and indoor air were simultaneously considered; their interactions were modeled.
The state of the Implementation of the European Energy Performance of Buildings Directive (EPBD) in Austria | 2006 | English
The process of implementation of the EPBD in Austria is now carried out for several years.
Study on Performance Evaluation of Mechanical Ventilation Systems for Occupied Houses | 2006 | English
In the first phase of the current project, the ventilation rates of occupied houses in the northern region of Japan were investigated from 2001 to 2005.
Ventilation Performances of Mixing, Displacement, and Impinging Jet System under Different HVAC Scenarios : Part II | 2006 | English
In most conditioned spaces, the Mixing Jet Ventilation (MJV) systems are commonly installed. Relying on turbulent mixing, MJV homogeneously controls the room environment.
The idea proposed in this paper is to control the HVAC equipment with predicting the heating/cooling loads and indoor conditions by computational simulation according to the target, such as energy consumption, energy cost, CO2 generation and indoo
