This paper looked into the possibilities of adaptive reusethrough the environmental retrofit of an existing warehouse. The project was built on the intent of convertingan abandoned building into an exhibition hall, within the tropical island climate of Subic Bay, Philippines.Analyses of the existing warehouse were undertaken;from this initial study, three main strategies were identified shading, the use of thermal mass, and ventilation.These three aspects formed the core of the research,and were further investigated through the use of computer simulations.
This study compares various optimization criteria for a solar domestic hot water system (SDHWS). First of all, we present the various parameters used to evaluate a SDHWS. We consider the energetic, exergetic, environmentaland financial analysis. Various optimization criteria of a standard solar hot water system are then proposed. The optimized solutions are compared with a standard hot water system.
The scope of the current paper is to present two buildingprojects that have been designed within 2006 by Gavalas Architects & Associates. On both of them, the main target was to produce a result of high functionality and innovative aesthetics while resulting a low-energy building, using mainly simple passive systems, providingthe best possible environment for the occupants. From a sustainability point of view, the main targets are: To reduce the energy consumption for heating during winter season and for cooling during summer season.
Every time with major frequency grows the necessity of energy efficient buildings, adapted to their environment, which consume and contaminate as least as possible.In this study it has been analyzed and evaluated the thermal conditioning of two blocks of flats, a renovation one and a new one, taking advantage of the bioclimatic technologies and using renewable sources of energy.
There are in Brazil ten million people in the south region of the country. In the south states of Brazil the buildings of social interest do not have any kind of heating possibility.Although it is hot in the most part of the country, in the winter there are some regions in south with negative temperatures. The costs of the energy and technology for heating are expensive. This makes with those who doesnt have financial conditions do not have thermal quality in the winter, because in this cases there are not any kind of heating systems in the buildings.
The buildings sector accounts for 40% of the energy requirements in Europe, which is more than by industryor transport. That is a lot and it is too much! Buildingstherefore have a major part to play in meeting the emissions reductions targets! And buildings of the futureshould therefore be designed in mutual cooperation in the design teams, i.e. between architects, developers,clients, engineers, etc. from day one of the design phase. This paper presents an EU supported project commenced in January 2007 looking especially on the processes of integrated energy design - IED.
Earth heat exchange (EHX) through buried horizontal air ducts (EHXair-hor) can be an effective passive/ibryde system to reduce heating and cooling loads in temperate climate zones. This paper shows the results of the authorsmost recent testing and design experience on the field. Conclusions are drawn in relation to the necessity of further monitoring and testing on more complex and variegated EHXair-hor systems.
Thermal insulation in the warm climate can reduce the energy demand for cooling in residential buildings up to 70%.To define the gap in between the actual applied thermal requirements and what would be todays economic optimum,Eurima ordered a study to Ecofys which also quantified the impact of thermal insulation in reducing the cooling demand in residential buildings.
