Hazardous compounds emitted during the plastic melting process were analyzed to indicate potentialair pollution issues associated with recycle plants for waste plastics. These hazardous compoundsmight be not only from polymer degradation but also from additives and print ink. To confirm what areemitted from them, melting experiments were conducted (150, 200 and 250C, in air or N2) and volatileorganic compounds (VOCs) emitted from samples were trapped by Tenax/Carboxen adsorption tubesand analyzed by TD-GC/MS.

Rapidly growing electricity demand brings into question the ability of traditional grids to expandcorrespondingly while providing reliable service. To solve such as these problems, this paperinvestigates current status of energy conservation and its systems in a complex hospital of Kitakyushu.Simultaneously, operation condition of energy-saving system and available strategy and prospectsabout improving system's effects, are discussed.

Volatile organic compounds (VOCs) emitted from various sources may adversely affect human health,comfort and performance. In particular, formaldehyde has been identified as a major indoor pollutantwhose emission is controlled by workstation systems. Engineered wood products such asparticleboards have widely been used with wood veneer and laminate to form work surfaces ofworkstation systems, which is a major formaldehyde emission component. The emission rate offormaldehyde depends on the composition of each material layer, temperature and moisture content inthe materials.

Hot water is an essential requirement in most Residence. Gas, electricity and furnace oil are beingused for obtaining hot water. These sources are not readily available and are scarce in a part of Japanat present. Fortunately, solar thermal energy is plentiful which can be successfully harnessed forgetting hot water. In this paper, performance of the copper coil heat exchanger type solar water heaterhas been described, which provides domestic hot water for a four-person family.

The ventilation efficiency of different ventilation patterns inside a room containing one person and officefurniture arranged by different inlet/outlet configurations was investigated. The numerical simulation(CFD) was first adopted to predict air flow pattern and ventilation performance. Then, a laboratoryexperimental measurement at room air distribution in a full-scale test chamber was conducted using thehot wire velocimetry (IFA300) to validate the simulation results.

Utilizing renewable energy systems (RES) is an important part of the design and development of greenbuildings. However, it is unreasonable to assess renewable energy utilization (REU) only with the netratio of renewable energy earning to a buildings total energy consumption, while ignoring the systemefficiency of RES with the additional conventional energy consumption, such as electricity. In this paper,the energy quality coefficient (EQC) is introduced to describe the quality of energy, while the energyconversion coefficient (ECC) is applied to evaluate energy system efficiency.

On the environmental problem, the university is considered as the education organ to play a guidingrole, it will be very important materials to grasp the consumption situation of the energy for saving theenergy, making consuming energy standards in the future. But there are few reports of energyconsumption about the Chinese campus at present. This article is aimed at Jilin Architectural and CivilEngineering Institute, and the situation of various energy sources consumption was investigated byfield survey and questionnaires.

Many existing Building Management systems (BMS) used for building services system control were notdesigned to incorporate records of occupant view and did not integrated the real-time occupantsresponse in order to fine tune the building services system to the individual demands in a dynamicmanner. This study based on a survey conducted for collecting occupants feedbacks towards indoorthermal environments, proposed a Bayesian approach in operation of building services systems ofair-conditioned buildings in a humid and subtropical climate in Hong Kong.

This study reports the findings from subjective responses of tropically-acclimatized people and theirrelationships with cutaneous indicators at three air temperatures, i.e. 20.0, 23.0, and 26.0C. A blindintervention study was conducted in a simulated office environment. Ninety-six subjects were recruitedand divided into 6 groups of 16 subjects. Each group was asked to perform simulated office tasks in theroom for a continuous four-hour session. The subjects also completed surveys on general thermalcomfort and sensations at various body locations.

Most of the electric power in China is from coal combustion power station, so that the pressure ofenvironmental protection is high. At the same time, there is big difference of development between EastChina and West China, which brings some difficulties to centralized power delivering. Because of itscharacteristics, distributed power (DP) can slow down these contradictions, so it develops quickly inChina.
