LoginA passive ventilation system using solar chimneys was designed to provide ventilation to several classrooms in an addition to an elementary school in Washington, DC.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
An HVAC circuit is a collection of interconnected elements that can be modelled by interconnected blocks.
Mixed mode ventilation is an effective way to reduce energy consumption as well as improve thermal comfort.
In order to address the lack of reliable methods that can analyze the overall effects of PDEC tower with a spray system, analytical models that predict supply air conditions of the system were implemented into a whole building energy simulation pr
Most controllers in Heating, Ventilation and Airconditioning (HVAC) applications remain the Proportional-Integral (PI) type.
Validations of implicit large eddy simulation were carried about two wind tunnel studies, which are flow and dispersion measurements around the building.
Where modern buildings are unable to maintain the internal environment to within comfort levels they often rely on mechanical systems to become habitable.
Buildings are the main consumers of electricity across the world. In the electricity system, it is critical to have a realistic forecast of buildings’ demand for adequate power planning and management.
The exponential increase of the cooling demand in buildings obliges to find alternatives to the high electricity consumption with air conditioning systems. This work investigates a new cooling system based on evaporation.
The scientific literature offers a number of methods for assessing the likelihood of overheating in buildings.
As the climate warms, the frequency and scale of extremely hot events are likely to increase. This study predicts overheating risk for the city of Sheffield, UK at a spatial resolution of 5km when the diurnal Urban Heat Island effect is included.
Among passive strategies to reduce energy consumption in buildings, we focus on natural ventilation, which can bring an important decrease in temperature during summer depending on climate.
This paper introduces a longitudinal study monitoring occupants’ window opening behaviour in a mixed-mode office building in Beijing, China, when natural ventilation is specifically used for controlling the building’s indoor thermal environment.
This paper discusses the impact of thermal zone modeling on the thermal comfort prediction during the early design of naturally ventilated buildings within four Brazilian cities.
Automated Calibration of Air Handling Unit Models using A Modified Preisach’S Model | 2015 | English
This paper presents a new approach to calibrate air handling unit models. This approach studies every heat exchanger component separately based on the inverse problem framework, the Preisach model of hysteresis and machine learning techniques.
Attic spaces belong among the most popular forms of housing or working.
In this paper, four different data-driven algorithms including AutoRegressive with eXternal inputs (ARX), State Space (SS), Subspace state space (N4S) and Bayesian Network (BN) are evaluated and compared using a case study of predictions of Air Ha
This research aims to define a modelling approach to simulate District Cooling Systems (DCS). A model of the network has been developed using the equation-based object-oriented language Modelica.
Different simplified simulation models of a Passive Downdraught Evaporative Cooling tower (PDEC) were compared by using experimental data.
Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings.
