Today Contemporary Technology is the basic factor for the environmental protection and the Sustainable Development. Greenhouse gas emissions reduction requires measurement taking on several thematic fields in order to achieve Kyoto protocol objective, which is reduction of polluted gas emission by 5% in global level and by 8% in EU countries. Energy and Transport are the basic fields where contemporary technology is going to intervene. The basic effort is focused on the use of environmental friendly fuels, which seems to cause big financial cost in first level.
Forward of the shortage of energy resources, the rational use of the energy started to be a subject of great relevance. In the last years, the countries come taking conscience of this and searching alternatives to optimise the energy use. For constructed buildings, the alternative is to use installations efficiently. In this purpose, a posoccupation evaluation becomes necessary to know the building performance and then helps an energy management. In countries of hot climate, the external temperature affects the thermal building performance and its energy consumption.
The integration of solar thermal systems, in buildings has been an aim of intense research over the last thirty years. Solar thermal systems have become the most widespread, and certainly the best-known RES system, being a commonly accepted solution for hot water production. Still, the integration of RES in the urban built environment remains limited, despite a series of ambitious demonstration projects carried out in the 1980s and 1990s and despite the significant progress monitored in the efficiency and performance of these systems.
A glazed space adjacent to an air-conditioned room is an innovative architectural solution to use the energy contribution of solar radiation in the winter and in the intermediate months, whereas in the summer adequate shading systems are needed. The sunspace is separated from the said room by a wall, generally in part opaque in part glazed, which acts as a collection system and directly removes the solar energy to the internal room through the glazed surface, and indirectly through the opaque surfaces.
The Sino-Italy Environment & Energy Building (SIEEB) is an intelligent, ecological and energyefficient building and seen as a model for a new generation of sustainable buildings. This paper describes the integrated design procedure for the SIEEB building design and the methodologies adopted for sustainable architecture and energy saving measures by using advanced technological solutions and control strategies. The results on the building energy simulation, plant optimisation and first estimation of CO2 emission reduction potential through SIEEB are also presented.
Most of studies on thermal comfort have been done considering the environmental conditions of the interior of the buildings, but for outdoor spaces the way to consider the sensation of thermal comfort it is not completely defined. A direct application of indoor comfort criteria for outdoor spaces is not appropriate because the variation of the climatic parameters is greater and faster than indoors. Due to seasonal variations, the acclimatization of the people to the local climate, influences enormously their appreciation of thermal comfort.
Human organism is probably the most perfect example of thermal behavior, adaptation to different climatic conditions, and a way of keeping it’s temperature constant, which is existent in nature. Observing various buildings, their thermal characteristics,
The paper describes methodology and results collected from a professional and research experience oriented to design, build up and monitor an innovative passive system for the preventive conservation of the ancient stained glass windows in the Assisis St. Francis Basilica Superior Church.
In Part 1, it is described that, in overall judgment, the reproduction accuracy is improved when computational fluid dynamics (CFD) is performed using RNG model and the modified model incorporating Durbins limiter (? = 0.65). However, in Part 1, the study was performed on an object with extremely simple shape, and question may arise if this is applied on an actual building. In this respect, we attempted in this study to perform similar evaluation on an object with complicated shape.
This paper looks at the ways in which summer overheating can be avoided in European - and in particular UK - office buildings. Starting with the results from field surveys expressed in adaptive comfort theory the paper defines comfortable conditions and the range of acceptable temperature around these in both free running buildings and those which are heated or cooled. Data from the EU project SCATs and other surveys is used to explore how an upper envelope of acceptable temperatures might be defined.
