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.
In recent years, the insulation and air-tightnesslevels of newly constructed houses in Japanhave been improved for purpose of energysaving. However, a reduced design of airpermeability (i.e.
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.
This paper discusses the possibility of asimple solar hot water pre-heating system fordomestic hot water supply. In Japan, the fossilfuel use for hot water supply amounts to about30% of the total in residential buildings.
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.
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.
This paper describes the history and background of the ventilation requirements. Thepaper starts with an overview of existinginternational requirements.
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.
Determination of the Chilled Water Temperature and Flow Rate of theRadiant Floor Cooling System in Residential Buildings | 2008 | English
This study aims to derive design data of thesupply chilled water temperature and water flowrate for the radiant floor cooling system inKorean residential buildings.
Honda Wako Building(hereinafter called HWB)" is ahigh efficiency saving energyoffice building with six floorshaving 52,138-m2 of total floorarea.
A Study on Thermal environment of the Raised-Floor Ondol with aVentilation System at an Apartrnent | 2008 | English
A radiant heating applied to floor, so called'Ondol', is a traditional heating method in Koreaand has been widely used.
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.
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.
