The objective of this work package was to develop a quality/performance control tool-box model – a concept from design to post construction life long management, using also BEMS/REMS-type procedures and prevailing methods. Quality control toolbox concept
In comfort control strategy there is an exciting development based on inclusive design: the user’s preferences and their behaviour have become central in the building services control strategy. Synergy between end-user and building is the ultimate in the
Motorized sun-controlled louvers and electrically heated glasses are installed in NIKKEN SEKKEITokyo Bldg. A lot of highly effective equipment systems are set up in this building. In this research,these energy conservation systems are measured and analyzed. This report explains the specificationof the building, equipments, and the window system. . As a result, it was confirmed that the exteriorblinds and a heat generating double glazing was effective in keeping thermal environment comfortableand saving energy.
The results of a case study are presented focusing on efforts to conserve energy in an existing cityblock by physically connecting a number of existing buildings with pipes and cables and aCogeneration System (CGS), and then exchange energy among the buildings using the CGS andexisting heat source equipment. Essentially, the proposed system levels-out and reduces variation inthe combined inter-building energy load among the buildings with a variety of energy use profiles.
Traditional method for measuring airborne microbes is based on two procedures called sampling andincubation. Sampling normally involves drawing a sampler from an air stream or room by means ofinstruments based on 3 types collecting-method, which named impaction, liquid impingement andfiltration. Incubation of agar plates typically requires several days.
This paper presents a numerical study of the coupled airflow and thermal environment in asemi-enclosed space surrounded by buildings. Our numerical simulation couples the heat transfercalculation and the computational fluid dynamic (CFD) airflow simulation in which a RNG(renormalization-group) k-? model is used. Both the solar radiation and building/ground thermal storagewere considered in the heat transfer part.
The large sample size test and statistic of thermophysical parameters of natural ventilated residentialbuildings in hot-summer and cold-winter area, including the indoor air temperature, relative humidity,and wind speed, was performed in this study. The basic situations of the occupant were investigated byquestionnaires. The thermal sensation subjective response of the occupant was investigated withASHRAE seven sensation scales.
In past 20 years, the average prevalence of asthma in China has been growing up from 0.9 % to about3.0 %. We carried out these studies to find out the reasons and relative molecular mechanisms. Datamultiple-regression was used for prevalence and risk factor investigation (1990-2000) and animalexperiments were used for mechanism study.
The measurement of moisture in building fabrics has been of interest for many years due to thepotentially devastating consequences of moisture problems within buildings. A range of potentialtechniques are available with which to measure the moisture content of building fabrics in-situ and thispaper focuses on one particular technique, the thermal dual-probe. Note that this method is distinctfrom the single probe technique. Essentially, a short pulse of electrical energy is applied to a wirewithin the heating needle.
