The author had participated IEAIECBCS Annexprojects since 1987, starting from Annex 16 forBEMS, ending at Annex 40 for Commissioning.I used to recognize how this line of continualset-up of subjects to optimize HVAC design andmaintenance through sy
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.
Experimental Study on Thermal Cognition Developed through DailyExperience in the Built Environment during Summer Seasons | 2008 | English
This paper discusses whether there is thermalcognition acquired through daily experience inthe built environment during summer seasons.For this purpose, we analysed the results of asubjective experiment to reveal the relationshipbetween subjective
Buildings are a man-made environment built innature.
Honda Wako Building(hereinafter called HWB)" is ahigh efficiency saving energyoffice building with six floorshaving 52,138-m2 of total floorarea.
Conventional air-conditioning control in a roomassumes perfect diffusion of temperature in theroom, and relies on a temperature sensorinstalled on the wall or ceiling of the room, or inthe return duct.
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 holistic aim of this study is to make clearthe possibility of passive cooling systems usingnatural cool sources produced by cyclic weatherchanges. Here in this study, we focused on apossible use of rainwater for cooling.
The IEA ECBCS: Research and Development for Near Zero Energy and Carbon Emissions in Buildings and Communities | 2008 | English
The Energy Conservation for Buildings andCommunities Systems (ECBCS) is anImplementing Agreement among 23 countriesof the IEA (International Energy Agency) forenergy research and development in buildingsand communities.
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
Recently, supplying glass space like atrium isbeing extended widely for introducing naturallight into a building, improving rest roomfunctions and having a pleasant workenvironment.
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.
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.
Experimental study was conducted onimproving air-conditioners' energy efficiencyusing hydroponic roof plants. The air-coolingeffect caused by the solar-shading andtranspiration of hydroponic-cultivated sweatpotato was measured.
