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.
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
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.
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.
Allowing for thermal comfort in free-running buildings in the newEuropean Standard EN 1 525 1 | 2008 | English
This paper describes some qf the thinking behind the thermal comfort provisions of the new European Standard EN1 525 1 (CEN:2007) for free-running buildings. This standard deals with all aspects on the indoor environment.
Study the Thermal Effect of Ceiling-mounted Light Fixturesfor a Displacement Ventilation System | 2008 | English
This paper investigates the thermal effect of ceiling-mounted light fixtures for a displacement ventilation system. The influence of fluorescent lainps on a ceiling is examined by computational fluid dynamics and experimental methods.
