Usually, Indoor thermal environment is controlled by temperature with wall mounted thermostat. Indoor temperature control could not be provided the thermal comfort at all the time because thermal comfort is influenced by many parameters of environment such as temperature, relative humidity, air velocity, activity level, clothing insulation and radiant temperature. The purpose of this study is that predicted mean vote(PMV) would be available as index as control parameter. And, Thermal comfort is evaluated both PMV control and temperature control by simulation and several cases were compared, in which the set-point temperature range of between 22℃ and 24℃ and, set-point PMV index through the respective heating season in the simulation. The results show that PMV control is better to maintain human comfort condition and to save the energy than ordinary set-point temperature. It is time to foster a comfortable indoor environment, while minimizing the energy consumption of building systems. The thermal comfort provides satisfaction of thermal environment and affects productivity of occupants in residential building.

This paper discusses the modeling methodologies and optimization methods for building energy system using time series auto regression artificial neural networks. The model can be integrated into energy solution tools for building energy assessment, optimization, and many other applications. The model predicts whole building energy consumptions as function of four input variables, dry bulb and wet bulb outdoor air temperatures, hour of day and type of day. To train and test the models, data from simulations are used for the analysis. Advanced computational methods are used for data analysis and preprocessing. Different neural network structures are tested along with various input and feedback delays to determine the one yielding the best results. The optimization method was also developed to automate the process of finding the best model structure that can produce the best accurate prediction against the actual data. The results show that the developed model can provide results sufficiently accurate for its use in various energy efficiency and saving estimation applications.

Development of sensing and measurement technology contribute greatly to the expansion of application using sensor based DCV (Demand Controlled Ventilation). So, in this study, It made investigation current state and problems of ventilation system and prospected of the alternative ventilation system using sensor based DCV system in high-rise residential building. It was setting up various sensor based DCV strategies that they are CO₂-DCV, TVOC-DCV, and IR(Infra-Red)-DCV for evaluation on characteristic of indoor contamination levels and analysis of energy consumption. As a result, sensor based DCV system is proper to maintain indoor air quality and to decrease outdoor air intake and energy consumption compare with 24 hour continuos ventilation system. CO₂-DCV appropriate to control carbon dioxide concentration in the each zone but can not control TVOC concentration. TVOC-DCV can control TVOC concentration better then CO₂-DCV but it appeared that period of CO₂ concentration is high. IR-DCV have benefits to control CO₂ concentration but can not control TVOC concentration during the vacant of occupant. And, the energy consumption decrease rate is approximately from 13 to 21 percent case by case basis by ventilation strategies for one year.

The underground utility tunnel is an installation of public facilities such as electricity, gas, water supply, waste water drainage, telephone and communication which are required for managing urban life. Acquiring the stability and reliability are regarded as important because it is the public facilities, which provide the conveniences in daily life, socio-economic activities of citizens; maintain the comfortable urban environment; and efficiently run cities. The underground utility tunnel facility is specified in the Urban Planning Act so as to aim for the aesthetic appearance of a city, preservation of road structure, and smooth flow of traffic.The underground utility tunnel is a very important infrastructure in modern urbanization. However, it is true that a lot of problems are being pointed out such as the reduction of air quality, reduction of ventilation volume, dew condensation and non-emission of poisonous gas due to the lack of smoke ventilating facilities in case of a fire breaking out in a utility channel because, in relative contrast to the rise in demand of underground utility tunnels in the city, the factors of underground space had not been reflected properly in the design and construction of underground utility tunnels and its maintenance system. Therefore, the purpose of this study is to establish a database for the environmental information of underground utility tunnels by measuring the temperature, humidity, surface temperature and air stream velocity in underground utility tunnels, and to use it as base data for maintaining. The underground utility tunnel located at Inchon, Korea was selected as the subject for the study. The point of measurement was the halfway point between the inlet and outlet of the utility tunnel. The air velocity with and without mechanical ventilation operation were compared and they were summarized. As a result of measuring the underground utility tunnel which was the subject of this study, it is considered that there will be almost no damages such as the weakening of structural durability, corrosion of indoor facilities and electric leakage of electric power facilities because the normal conditions. However, it is necessary to establish a database by collecting more data and additional measurement during spring, summer and winter.
