Wind Catcher and Solar Chimney Integrated As An Alternative Ventilation For Urban Dense Settlements In Tropical Climate

The high energy use for building operations in humid tropical climates is mostly used for operational mechanical ventilation such as air conditioning (AC) and fans. The use of large amounts of energy, especially fossil energy can reduce the quality of the environment, causing an increase in the temperature of the earth. Need more efforts for management of energy use by reducing fossil energy consumption. One effort that can be done is to replace mechanical production and utilize passive ventilation in buildings. this study is a literature review regarding the use of passive ventilation using a windcatcher integrated with solarc himneys. The use of windcatcher and the solar chimney is still very rare in Indonesia, but has the potential to solve thermal problems, especially in densely populated residential areas in cities that have the character of a humid tropical climate. The results of this study recommend criteria from windcatchers and soler chimney that might be applicable and adapt to the character of the urban humid tropical climate.

High Speed Railway

In recent years, the energy performance of public buildings has attracted substantial attention due to the significant energy-saving potential. As a semi-open high-space building, the high-speed railway station is obviously different from other public buildings and even traditional stations in terms of energy consumption and internal environment. This paper investigates the current energy consumption situation and environmental quality of 15 high-speed railway passenger stations in China. Results show that the energy consumption of the high-speed railway station is between 117–470 kWh/(m2·a). The energy consumption of the station is related to the area and the passenger flow. The energy use of the station using district heating is higher than that of the station without district heating in the same region. The higher glazing ratio induces good natural lighting in the station, but the uniformity of the lighting in the station is not good. The acceptable temperature range of passengers in winter is larger than that in summer. The average air change rate of the high-speed railway station is 3.2 h−1 in winter and 1.8 h−1 in summer, which is the main reason of high energy consumption of the HVAC (Heating Ventilation Air Conditioning) system in this kind of building.

Adequate food supplies and a reasonable quality of life require energy —both noncommercial and commercial forms. Energy is a prime mover of economic growth and development. Although the linkages between energy and development are complex and still imperfectly understood, energy undoubtedly fuels economic development. And the developing countries where most of the population growth is occurring face an energy crisis of staggering proportions. An ample energy supply is not an automatic guarantee of smooth economic advancement, social progress, or stability, but it is, indisputably, their essential precondition. The future of our increasingly interdependent world will thus be very much influenced by the success or failure of the developing countries to ensure a sufficient and sustainable flow of energy (Smil and Knowland, 1980). The global inequity in the use of commercial fuels is familiar. About 1.5 billion people live in countries where the per capita consumption is less than 7 gigajoules (GJ) y-1, and another 1.1 billion consume only 7-20 GJ y -. Let’s translate this into more meaningful terms: 7 GJ is the equivalent of about 180 1 of diesel fuel —or about 0.5 1 per day to cover all human needs, such as food production and cooking, shelter, heating, and clothing. Millions and millions of rural inhabitants use virtually no commercial fuel. Clearly, no one can achieve a desirable quality of life (QOL) with so little energy available (Leach, 1979). Many studies have related GNP and energy use, but scholars debate the correlation with QOL. When one considers that energy is required to produce all the basic needs of humans, it seems apparent that a relationship as shown in Figure 5.1 may exist. Morrison (1978) carried this concept a step further by expressing QOL as a function of energy use. At low levels of energy use (quadrant III), he hypothesized that basic need satisfaction is linearly related to energy use. As the amount of energy increases (quadrant II), two paths were hypothesized. Option A projects a linear relationship between QOL and energy use, whereas option B suggests an optimum QOL at a moderately high level of energy use, followed by a deterioration of QOL due to environmental degradation at excessively high energy use rates.

From whatever perspective we look upon the sustainability and health quality of housing, the quality improvement of the housing stock will be of major importance. To achieve the goals of reduction of fossil energy use, large scale refurbishments programs will have to be carried out. This goes together with the necessity to prevent the ageing stock from deterioration and to improve the physical quality of neighborhoods and dwellings for livability reasons.

Range Of Values

Efforts to achieve an energy transition often neglect to account for the levelling of benefits realizable with higher levels of energy use, despite knowledge of a saturation effect and recognition of increasing harms of use. This research examines energy sufficiency as a maximum quantity of energy associated with improvements in human well-being to inform a recalibration of energy targets among high-energy societies. A systematic review of recent research was performed to identify the point at which increasing levels of energy use no longer correlate with meaningful increases in well-being. For selected studies (n = 18), energy sufficiency values range from 60–221 gigajoules per capita per year with a mean of 132 gigajoules per capita per year for associated measures of well-being. The review finds agreement in a pattern of saturation and provides a range of values for energy sufficiency maximums, suggesting that a relatively modest amount and a diverse quality of energy is needed to support high levels of human well-being. Beyond the conventional emphasis on energy efficiency and renewable energy, energy sufficiency therefore offers a necessary and complementary approach for supporting just and ecological energy transitions.

The World

Efficiency has replaced productivity as the prime rationale for research and development in agriculture. The reasons for this are to (1) reduce input costs when output is static; (2) to make best use of limited renewable resources; (3) to conserve both non-renewable resources and the quality of the environment. Efficient agriculture and conservation are often seen as opposing arguments because parties are arguing from different, incomplete premises. Blaxter (1975) explored the biological efficiency of agricultural systems using energy as a unit of account. He recognised that it was primarily the use of fossil energy as fuel (0.42) and as fertiliser (0.38) that had increased the productivity of U.K. agriculture but that “in the long term …the world must eventually reach a steady state in which energy provision will not entail a depletion of its capital resources.“

Abstract Twelve quasi-identical almshouses with an architectural-historic value were reno-vated, because of their high energy use, poor indoor comfort and numerous moisture problems. Aerogel plaster was applied for the hygrothermal upgrade of the uninsulated brick walls, while limiting the reduction of living space in these very small houses and keeping the monumental character of the facades in their original state. Several quality assurance tests were executed to evaluate the quality of the renovation of the building envelope and to compare the results with the initial theoretical design calculations. It appeared that the existing materials performed considerably better than the assumed conservative default values. On the other hand, the newly installed insulation materials performed somewhat less than declared, for example due to on-site processing. This resulted in a strong overestimation of the improvement in thermal performance by the renovation works. Field measurements of the existing situation can help to close this gap.
