Energy and indoor environmental performance of buildings are highly influenced by outdoor/indoor climate, by building characteristics, and by occupants’ behaviour.
Valentina Fabi, Rune Vinther Andersen, Stefano Paolo Corgnati, Bjarne W. Olesen, Marco Filippi
In order to decrease the concentration of indoor pollutants, sorptive building materials have been used.
Janghoo Seo, Sunwoo Lee, Sumin Kim
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.
Yutaka Oura, Satoshi Sawaki, Yoshikazu Nomura, Katsuhiko Mori, Sihwan Lee, Miho Tanaka, Shinsuke Kato
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.
Sihwan Lee, Tanaka Miho, Shinsuke Kato
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.
Michael J. Brandemuehl, Kristin M. Field
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.
Nathan Mendes, Antonio César Silveira Baptista da Silva, Rogério Marcos Barbosa
In future highly energy-efficient buildings, heat pumps will play a key role.
Thomas Afjei, Ralf Dott
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.
Ilaria Ballarini, Vincenzo Corrado
Many simulation software to predict thermal environment of buildings, such as temperature, humidity, heating and cooling load of building spaces, have been developed.
Akihito Ozaki, Myonghyang Lee, Yuko Kuma
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

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.
Conrad Voelker and Oliver Kornadt
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).
Céline Villa, Raphaël Labayrade
To 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

District heating and cooling (DHC) systems show a great potential for energy saving.
Yoshitaka Uno, Shinya Nagae, Yoshiyuki Shimoda
Carbon dioxide concentration is often taken as an indicator of indoor air quality, especially in spaces where human beings are the main contaminant source.
André Isele, Gerrit Höfker, Malcolm Cook
 In the context of more and more efficient building research, as passive house or Energy plus building, the occupants have become a central actor of building system.
Hervé Chenailler, Stéphane Ploix, Frédéric Wurtz
Automatic optimization and degradation detection tool for HVAC primary system was developed. It synchronizes with Building Energy Management System (BEMS), and it does optimization and degradation diagnosis automatically.
Daisuke Sumiyoshi, Naomiki Matsushita, Je-Hyeon Lee, Yasunori Akashi
The diversity of non-domestic buildings at urban scale poses a number of difficulties to develop building stock models. This research proposes an engineering-based bottom-up stock model in a probabilistic manner to address these issues.
Wei Tian, Ruchi Choudhary
This study reported a series of wind tunnel experiments on the spatial distribution of the pressure drag acting on the walls of rectangular block arrays, which were arranged in staggered, square, and diamond layouts under the conditions of differe
