A push-pull fume cupboard is a device to capture chemical vapors in a laboratory or a factory.
The aim of this paper is to have a generaldiscussion of the status regarding energybuilding codes in relation to TAQ concerns.First, there is a brief discussion of the trends inenergy regulations and in IAQ concerns.
This paper presents a design method to definethe settings of HVAC systems in order toprovide thermal comfort in high MRTenvironment in hot climates.
In the desiccant dehumidifier using adsorbentsuch as silica gel and zeolite, outdoor moist airis dehumidified in adsorbent.
People who become too warm or too cool willadjust their clothing or reset building controls(windows, blinds, fans, thermostats) with theainz of restoring comfort or reducingdiscomfort, if they are free to do so.
Conflation of computational fluid dynamics(CFD) and building energy simulation (BES)has been used in recent years in order toimprove the estimation of surface coefficientsfor studies on thermal comfort, mold growthand other performance aspects of

Translucent thermal insulation walls forJapanese houses have been designed to allowsolar radiation and daylight to pass through thewalls into the house (Fig.
Comparison of Physical and Psychological Aspects of Light and Heat Radiation Brought by Daylighting | 2008 | English
This paper describes the merit of daylighting bycomparing the physical and psychologicalaspects of light and heat radiation.
Thermal adaptation in residential buildings in the Hot Summer and WinterCold Zone of China, case study of Wuhan in summer | 2008 | English
This field work was conducted in Wuhan in2007 summer to investigate local residents'thermal adaptation.
A survey of air conditioner temperaturesettings and clothing insulation was carried outfor university student rooms in June-Octoberduring daytime on weekdays in Osaka, Japan.The results are as follows.
A com~nonp ractice, adopted by several buildingenergy simulation (BES) tools, is the use ofsurface averaged wind pressure coefficients (Cp)instead of local Cp values with high resolutionin space.
Air tightness is an important property ofbuilding envelopes. It is a key factor indetermining infiltration and related wallperformanceproperties such as indoor airquality, maintainability and moisturebalance. Air leakage in U.S.
Sales data shows that the use of air-to-air heatpumps in New Zealand houses is rapidlyincreasing. This rapid uptake will lead to newenergy and peak power demands on theelectricity supply system.
A roof is one of the most importantcharacteristics of Thai architecture especiallyin a house, traditionally. Also, the roof is apart of the house that mainly effects energysaving due to heat allowance pass through andrelease from indoor space.
Exergy assessment of building energy use in China's hot summer and cold winter climate zone | 2008 | English
BEU accounting and assessment is a fundamental task for development of energy efficiency in buildings. The traditional methodology is based on caloric value of energy carriers, which is only relates to energy quantity.
