LoginTo achieve the low-carbon society, Japanese government has conducted; 1) to revise “Laws Concerning the Rational Use of Energy”, 2) to manifest reducing 25 % of CO2 emission, and 3) to participate COP15 as international activity. Various technique
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.
A multiobjective optimisation methodology is proposed to optimise building design against both physical performance (such as energy efficiency) and psychophysical performance (such as occupant comfort).
When coupling computational fluid dynamics (CFD) with a detailed thermal comfort model describing the human thermoregulation, the characteristics of the micro-climate of the human body have to be known.
In this paper we present a method to simulate res-idential building occupants’ activities, which can be directly used to predict occupants’ presence and as an input to models of occupants’ behavior, resulting in more coherent and accurate predicti
Many simulation software to predict thermal environment of buildings, such as temperature, humidity, heating and cooling load of building spaces, have been developed.
The aim of the work is to present a new methodology that allows to identify the most important parameters affecting the energy performance of buildings under certain conditions.
In future highly energy-efficient buildings, heat pumps will play a key role.
Evaporative cooling is an attractive energy-efficient technique for producing a comfortable indoor environment. The efficiency and low cost of water spray evaporative cooling systems makes them a good alternative to reduce energy use.
The objective of the work is to identify the types of occupant-driven residential behaviour variations that most significantly impact a designer’s ability to predict energy consumption and peak electrical demand of a house.
We designed a new air supply window system to ventilate indoors through the air space of a double pane window and evaluated its insulation efficiency and probability of moisture condensation in order to confirm its feasibility and applicability.
It is important to insulate the glazing or frames of windows efficiently because they usually contribute to some of the greatest heat loss from dwelling houses.
In order to decrease the concentration of indoor pollutants, sorptive building materials have been used.
Energy and indoor environmental performance of buildings are highly influenced by outdoor/indoor climate, by building characteristics, and by occupants’ behaviour.
This research investigates glare control strategies in reference to operational energy consumption and productivity for sustainable upgrades of existing buildings in two very different climate zones.
Modeling of heat transfer in geothermal heat exchanger using GHZ zonal model method | 2011 | English
Two types of Ground Heat Exchanger (GHX) zonal models are suggested for a new analysis method that can reduce analysis time and reflecting heat transfer mechanisms occurring on the GHX section; using a circular pattern (Circular) and replacing the
The Test Reference Year (TRY) weather file was developed in 1993; in 2009 the Typical Meteorological Year (TMY) became the new standard weather file to use in energy based simulations.
This paper presents a case study of the role that Computational Fluid Dynamics (CFD) played in the design of modifications to the existing Hamer Hall auditorium Heating Ventilation and Air-Conditioning (HVAC) systems. The use of CFD allowed the de
Research experts participating in the International Energy Agency (IEA) Task 40 project on Net Zero Energy Buildings (Net ZEB) were asked to classify their countries climate.
Multi-objective optimization algorithms are used in the building design process to find optimal solutions for design problems. Typically, these algorithms provide the decision maker with a Pareto front containing trade-off solutions.
