LoginThe current work presents features of an air-underfloor heating system and CFD model to predict velocity and temperature distribution. The paper describes the constructions of air-underfloor heat exchangers.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
During the last years much interest has been paid to Low Temperature Systems, i.e.
We present a representational framework for the integrated operation of multiple environmental systems in buildings. A methodology for the automatic generation of this framework is introduced.
The primary aim of the present study was to evaluate thermal storage performance of the storage medium embedded with metal fins and to prepare and accumulate design data.
This study discusses charging and discharging performance in building thermal mass storage systems. Building thermal mass storage systems utilize the thermal masses of the beams and the concrete floor slab to absorb cool energy that is produced us
This study develops a simplified estimation method for calculating the effective opening area of automatically operated entrance doors and the winter airflow rate into entrance halls due to the stack effect.
When applying the radiant floor cooling system, it is important to prevent condensation on the floor surface. To solve this problem, a radiant floor cooling system integrated with the dehumidification system has been proposed and evaluated.
Many studies have been performed on floor heating systems.
Validation is the key when attempting to instill confidence in a building simulation tool.
The paper presents the advanced use of S-Functions, facilitated by the Matlab/SimuLink environment.
For many buildings, continuous operation of the air conditioning system is not necessary for achieving thermal comfort during the occupied periods. Depending on the building's thermal and operational characteristics the air conditioning system may
Conventional building control systems usually apply central control schemes that do not fully address individual occupancy differences in built environmental requirements.
In order to reduce the environmental load (energy and materials) of buildings, a study was undertaken to develop and assess solutions for a dynamic, weather and daytime adaptable office façade. The following steps have been taken:
This paper presents the results of an empirical study to establish if and to which extent professionals in design community are familiar with and use building performance simulation applications.
A simulation methodology has been created for establishing the impact of increasing the insulation of the building envelope upon its global thermal performance and annual energy consumption (heating plus cooling).

The objective of this paper is to present an analysis of the weather data contained in a Typical Meteorological Year (TMY) and observe the effect of these data on the simulated load of a typical building.
Simulation exercises covering long periods (e.g.. annual simulations) can produce large quantities of data.
In the mid 1980s the monolithic nature of building energy simulation programs led to proposals for development of so-called "kernel systems," i.e., software environments that would make available to developers basic software modules and a supporti
Daylight design for “extremely” obstructed urban environment is a relatively uncharted area of study. No city in the world has an urban density as high as Hong Kong. Designing daylight in the territory is a critical and important study.
