LoginThis paper presents a numerical model for the analysis of impact of building envelope porosity on energy.
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.
Many existing building energy performance assessment frameworks, quantifying and categorising buildings post occupancy, offer limited feedback on design decisions.
While most of the existing artificial neural networks (ANN) models for building energy prediction are static in nature, this paper evaluates the performance of adaptive ANN models that are capable of adapting themselves to unexpected pattern chang
This paper presents first steps of a methodology for calibration of building simulation models through definition of the parameters that most affect the main electric end-uses of a building.
Natural night ventilation is an energy efficient way to improve thermal summer comfort. Coupled thermal and ventilation simulation tools predict the performances.
A finite differences numerical model for buried pipe systems is presented, accounting for sensible as well as for latent heat exchanges, so as for fully three dimensional heat diffusion in soil and flexible border conditions.
We present a model for calculating the sky radiation values considering the sky radiance distribution for a simulated building.
This paper reports on the measured performance of a residential solar water heater system over a period of 22 years and the modeling of the system to simulate its degradation over that period.
Past research of predictive optimal control of active and passive building thermal storage inventory has confirmed the importance of accuracy in the employed building model.
CFD calculations on night cooling by natural ventilation have been carried out for two different opening geometries: 1) a set of panels and 2) a 'parallel window'. Ventilation rates for these geometries have also been measured in a research facili
This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force.
This paper studies in three-dimension the coupled convective and radiative heat transfer rate from a window surface with adjacent aluminium venetian blind using commercially available CFD software. The flow patterns (temperature and velocity field
There is a strong demand for accurate moisture modelling since moisture poses a risk for both the constructions and the indoor climate. Thus, in this investigation there is special focus on moisture modelling.
In the world-wide scale outbreak of SARS in 2003, cluster of cases occurred in large building blocks, especially in Hong Kong.
This paper is about the application of a local (radiant) bench heating system in a church.
Previous simulations predict the possibility of reducing cooling demands in office buildings in hot arid areas if a selective double skin facade is used. The reductions on cooling loads in rooms range between 19%-40% depending on the glazing therm
The tendency to impose stricter building regulations in order to further decrease energy consumption contradicts the tendency to build more transparent architecture and apply thinner façade construction elements.
In a survey recently conducted by ECN and the University of Utrecht in The Netherlands [Visscher, Oonk et al, 2004]), several potential thermo chemical materials (TCM's) for seasonal storage of solar heat were determined.
This paper presents the results of a case study in which Low Temperature radiators, High Temperature radiators and floor heating systems are compared using a TRNSYS16-model of a typical erraced house.
This paper presents the results of a comparison between measurements of a co-heating test in a passive house and the simulated response of the building to the same outdoor conditions calculated with the building simulation program Trnsys. Special
