LoginThe Loop Equation Design Method has been proposed for sizing ventilation airflow components of natural and hybrid ventilation systems.
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.
External shading devices have been utilized very extensively in residential buildings in the tropics to reduce the amount of solar radiation entering into the buildings.
The present paper addresses and fosters the factors that affect airflow movement and energy efficiencies in the surgical operating theatres.
The balance between the energy efficient thermal comfort and Indoor Air Quality (IAQ) in healthcare facilities is the main of this paper. The present paper will present this balance from the viewpoint of the air conditioning design.
Condensation and mold problems have been identified as one of the severest IAQ problems in Japan.
The necessity of focus on more large integration of passive concepts for indoor climate conditioning is today a reality.
An improper air distribution within air-conditioned rooms is one of the largest causes of inadequate indoor air quality and thermal comfort.
Present international standard for thermal comfort such as ASHRAE Standard 55 and ISO 7730 were developed to serve as a guideline for moderate thermal environments e.g. mechanically airconditioned spaces [CEN ISO 1995].
At the new institute building of Fraunhofer ISE, both mechanical and free night ventilation is used for passive cooling of the offices.
In this work two numerical models are presented.
Considering the natural ventilation, the thermal behavior of buildings can be described by a linear time varying model. In this paper, we describe an implementation of model reduction of linear time varying systems.
The design for the new Federal Building for San Francisco includes an office tower that is to be naturally ventilated.
For the multi-room ventilation calculations, bi-directional flows or counter flows in openings have been rarely taken into consideration and only uni-directional flows have been allowed for the calculation.
From the view point of designing the energy efficient air conditioning system with maximized ventilation, the possibility of an all fresh air system was discussed using the simulation results of a model building in Tokyo.
In the frame of the IEA Future Buildings Forum, a workshop was held January 15 -17 2003 in St. Moritz, Switzerland.
The scope of the program SUBURET is to develop tools and design methods for advanced retrofit, to demonstrate successful retrofit concepts and to perform a technical and social evaluation.
Buildings leak water and air : it is normal and impossible to avoid.
In the 1970's variable-air-volume (VAV) revolutionized the use of air-conditioning for commercial buildings.
The aim of that study was to demonstrate the potential to design buildings that can simultaneously improve indoor environmental quality along with a reduction of energy.
In this one-page paper the author points out the misinformation related to IAQ. He gives a liste of myths and truths about it.
