Algemene ideeën omtrent de toepassing van globale duurzaamheidsprincipes in de stedelijke gebouwde omgeving worden gepresenteerd en bediscussieerd op een kritische manier. A comparison is made of the performance of thermal indices and subjective rating-scales, the temperatures for thermal neutrality, the effect of temperatures different from these, the standard deviations of the responses to temperature, and the distribution of the responses among the scale categories. The article discusses structural considerations, drainage requirements; planting soils and maintenance with regards to roofscaping. The growing complexity in environmental degradation requires a serious action for adopting sustainable initiatives in the different institutions design and operation. For each passive solution a devoted simplified model is introduced. In fact, all the main meteorological parameters are severely affected, resulting in the development of a local climatic regime, which is characterized by increases in temperature the heat-island effect and reduction of humidity and wind.
The system provides a new design paradigm based on the requirements of the Malaysian Green Building Index. The evaluation shows that passive cooling has an important impact on the thermal summer comfort in the building. Der Verfasser warfare seit 1934 im Brückenbau tätig und hat durch viele Neuerungen zu dieser Entwicklung beigetragen, er schöpft daher aus reicher eigener praktischer Erfahrung. This is especially apparent when certain climatic characteristics are considered, e. In this article the overall thermal comfort in the office building is evaluated by means of measuring and simulation results. The highly reflective material on outer walls and roofs is a significant way to prevent heat from penetrating indoors; such materials have been installed on the surface of buildings in Osaka, Japan.
A new method of estimating the median warmth response is presented and tabulated. Energy consumption for space cooling is growing rapidly, increasing the need for alternative low-energy solutions. In office buildings, the use of passive cooling techniques combined with a reduced cooling load may result in a good thermal summer comfort and therefore save cooling energy consumption. Data from over thirty field-studies of thermal comfort are collected and tabulated. Samenvatting Deze paper wil voornamelijk de onderwerpen gerelateerd aan energie-en milieuproblemen in steden analyseren.
The methods of study and analysis are critically described. To conclude, this book describesclearly and technically correctly the fundamentalsof passivecooling including analytical and experimental methods neededfor its successful practical implementationand will serveasan excellent teaching and learning text. Under the same urbanization pressure, the local climate in large metropolitan areas is also altered. This paper introduces a process that highlights each strategy's applicability by month. The aim of this chapter is to underline and review the recent state-of-the-art technologies for passive cooling convective strategies for buildings and their contribution in the improvement of the indoor environmental quality as well as in the reduction of cooling needs. The author points out that hazardous sites are frequently the ones with the greatest locational advantage for situating human activities, and suggests that mankind's highest priority should be to shape and control the enormous urban environment that is emerging.
Within this context this research was carried out on a pre-existing urban layout that has little to do with what is known as solar urbanism Amado, 2014. The aim of this research is to demonstrate the effectiveness of the design concept without the need for any chemical, complex, or expensive solar design techniques. Based behavioral survey scenarios were deduced from a questionnaire analysis in both winter and summer seasons. Hence, the climate analysis includes the incidence of sunlight and passive cooling Santamouris, 1996. As property costs and concerns for the quality of the urban environment increase, however, developers are becoming increasingly attracted to the roof as an additional outdoor space. In hot dry climates, natural ventilation is considered one of the most important passive cooling strategies. It allows you to enhance potency and economize in every kind of structures and vegetation, starting from person homes to advertisement constructions to giant associations and business crops.
In summer, the earth-to-air heat exchanger cools the ventilation air by day. It becameone of the strategic technologics aimed to increasebuilding's energy efficiency. One of the important countermeasures to the heat island effect is to reduce thermal storage in buildings. Description: 1 online resource 485 pages. The results of this research would potentially help Effat University to improve the campus environmental and energy performance through recommending a set of evidence-driven actions that can help in reducing heat island effect and enhance the efficiency of the university landscape sitting and material.
The first Chapter reviews the history andenergy consumption for cooling in buildings, air-conditioning technologies an3 systemsversus natural ventilation technology. Factor analysis was carried out in summer taking into account the greater influence of the climate factors in the warm region under study. In winter, the supply air is successively heated by the earth-to-air heat exchanger and the regenerative heat exchanger, which recovers the heat from the exhaust air. This is part of a specific plan which targets at the implementation of smart grid related research, training, innovation and dissemination activities. Computa- tional results were compared to field data col- lected during consecutive three-day experimen- tal campaigns that took place in the summer pe- riod.

With higher knowledge of the necessity to decrease strength intake comes a progress of curiosity in passive cooling, rather in its place to air-conditioning.
Passive cooling dissipative systems, based on heat dissipation through heat sinks air, water, ground, … , can constitute a valid alternative to mechanical cooling at least to reduce the hours in which auxiliary cooling energy is needed. Together they consist of over 200,000 observations made in a variety of climates. The choice of material, the exposition and the approachareattractive, valuable and in the sametime encouraging self study and exploration of new conceptsin passivecooling. The paper sets out the changing patterns of global urbanization against a brief historical background, showing the recent and transitory nature of the dominance of European urbanization. The choice of material, the exposition and the approachareattractive, valuable and in the sametime encouraging self study and exploration of new conceptsin passivecooling. Thermal Analysis and Design of Passive Solar Buildings is an important contribution towards the optimization of buildings as systems that act as natural filters between the indoor and outdoor environments, while maximizing the utilization of solar energy.
The process starts with a basic monthly categorization of the climate based on temperature, categories are then refined in a more detailed manner using a time table plot, guided by psychrometric and average diurnal temperature charts, information is extracted in conjunction with the wind wheel that graphically plots speed, direction, and frequency. This paper discusses the effectiveness of occupant behavioral strategies of open and close windows on indoor thermal comfort in residential buildings in the hot arid climate of Cairo, Egypt. When properly designed and constructed, however, planted roofscapes can satisfy a roof's primary goals - structural support and protection from temperature variation and water penetration - while enhancing a structure's usefulness and attractiveness. With greater awareness of the need to reduce energy consumption comes a growth of interest in passive cooling, particularly as an alternative to air-conditioning. Chaptersnine and ten are devoted to the most important theoretical and empirical descriptionand prediction methods of natural ventilation processes, sun'smotion and solar radiation, solarirradiance andcontrol in buildings.
