LoginThe conservation policies and Rational Use of Energy (RUE) developed until the present, had their origin in the search of a smaller energetic consumption in order to reduce economic costs in a growing prices market of the fuels.
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.
The frame work of methodical design as developed at the University of technology Twente is used to specify dynamic system design/configuration concepts and alternatives for HVAC-installations (Heating Ventilation And Air Conditioning).
Hollow core ventilated slab systems provide an effective means of utilizing the building structure as a thermal store to reduce energy cost while maintaining the thermal comfort of the occupants.
This paper discusses the use of a building thermal analysis methodology in which the stochastic nature of the external climates and randomness of physical parameters are considered.
During the past two decades, pressure on the building industry increased gradually. Energy effi-ciency, indoor air quality, comfort, durability, sustainability all became key issues within a framework of growing cost awareness.
Physiological and sensory responses, particularly paid attention to the skin wettedness under clothing at constant average skin temperature, were observed in two male subjects while they were seated on a balance.
A field study on thermal comfort has been carried out in the capital city of Jakarta, Indonesia. There were 596 office workers working in seven multi-storey office buildings participated in this study.
This paper presents a new method for monitoring the performance of control loops. The method determines performance indices using recursive relationships.
This paper presents laboratory and field test results for a new pattern recognition adaptive controller (PRAC) that adjusts the gain and integral of proportional-integral controllers while under closed loop control.
For new design approaches the engineers of HVAC systems need tools for estimating energy requirements of different heating systems in advance. The heat losses of buildings can be classified into three fields.
The aim of this work is to present a simulation programme for PCs which is easy to use and yields quick results of daylighting along the day in an indoor environment provided with a lightshelf, and solar irradiation levels on the external faade of
CA-SIS,Conditionnement d’Air - Simulation des Systèmes (Air Conditioning - System SImulation), software has been developed on PC as a tool for engineering offices in their Heating, Ventilating and Air Conditioning studies.
Through this paper we describe the introduction of a comprehensive routine, able to take into account air changes needed for IAQ purposes, in a computer simulation code based on the explicit form of the finite difference method and devoted to the
A dynamic model based on physical laws and field measurements has been developed to simulate temperature, humidity and gas concentration in livestock buildings and the emission of ammonia from these buildings.
This paper compares the results obtained with the simplified sizing methodologies for thermal energy storage components usual in HVAC current practice and those obtained from an optimised procedure based on hourly simulations.
In the last years, as fenestration and shading systems have become more complex and sophisticated, a great improvement of thermal and solar-optical performance has been required and as a consequence old methods of characterization have become inad
It has been shown by previous researchers that Artificial Neural Networks (ANNs) not only be used to predict energy more reliably than traditional simulation models and regression techniques but can also from the basis for a predictive controller
Defrosting in supermarket refrigeration systems is normally controlled by a preset time cycle with most display cabinets timed to defrost every 6 hours.
The article shows the results of a case study dealing with indoor daylighting concepts and practice.
