A Study on Thermal environment of the Raised-Floor Ondol with aVentilation System at an Apartrnent | 2008 | English
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.
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.
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.
Energy-efficient building design often makes use of night-time ventilation or thermal slab activation. The quality of the design tools used depends on the quality of the empirical valuesused within them such as heat transfer coefficients.
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.
On the Influence of the Reynolds-Stress Anisotro y Tensor on thePrediction of Wall-Affected Three-Dimensional Room airflows | 2008 | English
It is well known that the turbulence anisotropyhas a remarkable influence on the flow of threedimensional wall jets.
In the desiccant dehumidifier using adsorbentsuch as silica gel and zeolite, outdoor moist airis dehumidified in adsorbent.
Design Engineering Review of Two Canadian Displacement VentilationApproaches with in-situ Performance Measurement of the Buildings | 2008 | English
Displacement Ventilation approach is becomingan interesting alternative to mixing ventilationainong Canadian consulting engineers. Thispaper presents two recent DisplacementVentilation projects designed by two inajorCanadian engineering firms.
A new innovative design concept for the indoorair conditioning systems is proposed. Thisconcept uses passive control and modularly airdiffusion devices and aims complying with boththernial conifort and energy efficiencyobjectives.
In this work the problem of the estimation of achange in the dynamics and time-varyingthermal parameters for a wall from experimentaldata is solved in several ways.
"At the G8 Hokkaido Toyal
Honda Wako Building(hereinafter called HWB)" is ahigh efficiency saving energyoffice building with six floorshaving 52,138-m2 of total floorarea.
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.
Development of behavioural algorithms for thermal simulation of buildings- evaluating constraints on the operation of windows and fans | 2008 | English
Realistic knowledge of window-opening andfans use behaviour is needed, for the thermalsimulation of naturally ventilated buildings. Ifcontrols such us windows and fans wereefective and easy to use, thermal discomfortcould be largely avoided.
Experimental and numerical study of air temperature distribution of anunderfloor air distribution system | 2008 | English
A numerical model of an underfloor air distribution system was created to aid future research on the system's environmental performance. A validated numerical model can serve to minimize the need for costly experimental setups.
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.
A Case Study of Energy Consumption and Indoor Environment in a WoodConstructed Office Building | 2008 | English
In this study, field measurements andinvestigations have been carried out tounderstand the energy consumption and indoorenvironment of a sustainable designed officebuilding.
The effect of downdraft spoilers is questioned.CFD results are presented for a large atriumequipped with downdraft spoilers ("obstacles")to counteract downdraft from glazed faqades.Simulations are in addition presented for oneandtwo-story test roo
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.
