LoginThe paper presents an application of a new method to simplify models of heat sources in CFD simulations of large spaces exposed to variable occupancy patterns.
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.
The paper focuses on control optimization of nonlinear system models where the differential-algebraic equations are formulated in Modelica.
In this paper, predictive models are developed to enable the application of model predictive control (MPC) to naturally ventilated buildings.
A passive ventilation system using solar chimneys was designed to provide ventilation to several classrooms in an addition to an elementary school in Washington, DC.
Minimum levels of attic ventilation have been required by residential building codes in the United States for years, but the precise attic temperature reductions of “poking holes in the roof” and corresponding energy impacts have rarely been robus
Contamination distributions were calculated and evaluated by contamination area ratio at respiration height for actual smoking rooms. As a result, 1) Dust contamination area ratio is about 20 % for required ventilation volume by Guidelines.
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.
In the frame of a multi-year EU project, the set of European Standards from 2006/7 to support the European Energy Performance of Buildings Directive (EPBD) is undergoing a revision. The majority of the standards describe calculation methods.
This paper presents an analysis of internal air temperatures measured hourly in the living rooms of 10 domestic buildings in the city of Leicester, UK.
Building form is one of the most critical factors influencing natural ventilation potential in an urban context, and thus has a significant impact on building energy consumption.
The paper presents a laboratory investigation about cork-cement mixtures designed for building applications. Samples are prepared by mixing cork aggregates, sand, cement and water.
In the absence of thermal comfort standards in India, architects and designers have no choice, except to provide air conditioning to meet thermal comfort criteria for achieving green building rating for their projects and thus end up using more en
Residential and commercial buildings use nearly 75% of the overall electrical energy in the U.S., and the amount of renewable energy in the grid keeps increasing.
Building performance simulation has been utilised for the investigation of thermal comfort and airflow within a naturally ventilated, self-sufficient house in a bushfire prone area.
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
In this study, it is a purpose to grasp the effect of natural ventilation in the apartment house. This study targeted the apartment house of 14 floors.
Validations of implicit large eddy simulation were carried about two wind tunnel studies, which are flow and dispersion measurements around the building.
Double skin façades (DSF), are typically composed by two transparent envelope elements separated by a ventilated airspace.
Occupant behavior is a major contributing factor to building energy consumption.
