Measure Methods

For many elderly people, residential energy conservation options are often limited to little or no cost measures such as reducing their winter nighttime thermostat setting. As a result, conflicts can arise between the need to preserve health and the necessity to conserve energy. Under these circumstances, accidental hypothermia is an important and growing concern. This study examines the association between concern for health and the adoption by elderly persons of a lowered winter nighttime thermostat setting. Evidence from two surveys of elderly respondents who maintain separate owner-occupied residences shows that health and thermal comfort concerns are the major reasons for nonadoption of this energy conservation measure. Methods are presented for increasing energy conservation while maintaining a healthful home environment.

Decision Support Process

Building energy conservation measure (ECM) of insulation materials suitable for the domestic situation in the construction sector (passive) is established. The ECMs of insulation materials were classified into walls, roofs, and floors. Also, economic evaluation databases, which are composed of material costs, labor costs, and expenses for constructed alternatives, were built. After setting the target building and deriving the ECM list of insulation materials for the target building, the energy use evaluation and economic evaluation were performed for each constructed alternative. Based on this, the optimal building energy conservation measure of the target building was derived by applying the decision-support process.

The Impact

The world has gone beyond the realization that fossil fuels are a depleted energy source, that the earth is going through a global warming phase, and that it is important to find the necessary energy alternatives, with the least environmental impact, and to address energy consumption in the building sector in particular. Passive systems and their use, or combined with effective systems. due to the dependence of the Iraqi urban environment on the electricitySignificantly and the source of fossil fuel, it is important to find suitable solutions, especially in the summer because of high temperatures and increased drought, by taking advantage of the experiences of countries within this scope, and applied to buildings , Because the roof is the main source of thermal gain inside the buildings it is necessary to take the systems of cool roofs, which is a passive system in the roofing of buildings, contribute to improving the internal environment and achieve the thermal comfort of the occupants, the research problem was:"There is no clear conception of the possibility of applying cool roof systems in the local administrative buildings" and The objective of the research is to" clarify the importance of achieving the concept of conservation of energy and improve thermal performance through the application of cool roof systems in the administrative buildings in the urban environment of Iraq with a hot- dry climate, "and then ensure the research Two aspects,first one:The concept of thermal performance and conservation of energy in administrative buildings and the way of achieving energy conservation using cool roofs, while the practical side included: the handling of several global experiences of sustainable administrative buildings used cool roofs and indicate the impact of this system on the efficiency of thermal performance, The research concluded that it is possible to apply cool roofs in claimte of  Iraq (hot-dry) because the cool roof has the ability to reflect a large amount of solar radiation falling on the surface of the roof, thereby reducing the thermal gain of the building and improve the thermal performance of the administrative building envelope, and as a result achieved Save energy within its spaces

The objective of this study is to conduct a field survey, including data collection and measurements to study the potential of energy conservation measure of Rerm-Udom sugar factory in Udon Thani. The boiler efficiency is measured and calculated using the indirect method. The results of this study show that the most significant loss of the boilers is heat loss due to exhaust gas, which is 17.2%, while the rest heat loss is around 2%. The proposed energy conservation measure to improve the performance of the boiler is to install the economizer, which helps to increase the boiler efficiency for 1.5% and helps to produce additional electricity for 2,362,800 kWh per year or 7,088,400 Baht per year. The investment cost of the economizer is 7,200,000 Baht and the maintenance cost is around 1,000,000 Baht per year. Therefore, the payback period of the energy conservation measure is 1.2 years.
