LoginThis paper presents the development of a simulation tool based on the Matlab computational environment for building temperature performance analysis with automatic control.
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.
This paper will address the shortcomings of typical heat balance-based HVAC design and analysis software when applied to thermal displacement ventilation (TDV) system design.
With the advancement of technology, and with the widespread availability of simulation tools, we are forced to consider which simulation tool would be appropriate for a particular problem.
Air supply diffusers used in air-conditioning systems can be classified as ceiling diffusers, sidewall diffusers, floor diffusers, jet nozzles, and low velocity displacement diffusers.
The hygrothermal behavior of a building component exposed to weather is an important aspect of the overall performance of a building.
Convective air circulation occurring through wall layers is frequently observed in building envelopes.
Air infiltration through revolving doors may have significant impact on the heating load of commercial and institutional spaces, and may create discomfort to people. This paper modifies a 40-year old model by Schutrum et al.
The Loop Equation Design Method has been proposed for sizing ventilation airflow components of natural and hybrid ventilation systems.
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.
