LoginThis study is focused on the ground heat pump (GHP) used in heating single-family houses. These systems generate a ground heat depletion which decreases its performances after several years of operation.
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 investigates airflow in an office room with a displacement ventilation system parametrically using three-dimensional CFD.
Multizone network models employ several assumptions, such as uniform pressure and quiescent air inside the zone, which may cause inaccurate results in flow calculations.
Active diffusing light pipes (such as hollow tubular lighting) are means of directing and diffusion light (daylight or electrical light) into interior spaces. The two principal objectives of this paper are : 1) to show the development of an advanc
This paper describes how the energy performance of single storey multiple-skin facades can be optimized by changing the settings of the facades and HVAC system. The energy performance is analyzed with a yearly whole building energy analysis under
A desiccant cooling unit powered by 14.8 m2 of solar liquid collectors is implemented in a training room in Chambery in Eastern France.
Different heating system controllers for passive solar buildings are compared on two different buildings. The performance criterion combines energy performance and thermal comfort using the "cost function" paradigm.
Dynamic, three-dimensional models of existing facilities that are updated automatically based on data provided by advanced sensing technologies appear increasingly feasible.
Moisture is one of the main problems in buildings. In spite of the complexity to describe moisture physical phenomena, recent technological improvements have allowed them to be incorporated into building simulation programs.
The hygrothermal environment of the Japanese traditional house constructed by wet process with clay wall and the recent house constructed with industrial building materials are estimated through the interrelated simulation of heat and moisture tra
This paper proposes a method for creating an extreme seven-day weather data set for HVAC design purposes and examines its suitability.
This paper complements a previous publication in the Building Simulation Conference series by identifying where perceptualization techniques can improve data presentation and assist with the interpretation of the underlying performance message.
The introduction of EU directives 2002/91/EC and 2003/87/EC both prompt a reduction in energy consumption from European buildings. Buildings account for 50% of European energy use.
The models for photovoltaic (PV) systems currently in ESP-r prove very useful in estimating the electrical and thermal impact of building-integrated photovoltaics.
A simplified optimization process (SOP) for determining set points is proposed and evaluated using the monitoring data and model of an existing VAV system.
CEN TC247 has prepared draft standards for main types of room controllers. These standards include a performance testing procedure that was designed to facilitate the introduction on the market of electronic controllers.
Tall buildings pose unique challenges for simulation software and modelers. Environmental factors such as air temperature and wind speed change with altitude.
In this paper, four different system configurations:
An optimal controller for auxiliary heating of passive solar buildings and commercial buildings with high internal gains is tested in simulation.
Earth-to-Air Heat Exchanger (ETAHE) technology has been implemented in many mechanical ventilation systems. A literature review revealed that recent advancements in ETAHE modeling were focused on simulating heat conduction in soil.
