Real-time control of comfort in indoor spaces needs models of temperature distribution and air-velocity velocityfield. Currently, a one zone model is used assumingthat the temperature is homogenous in the whole space. If the heterogeneity of air velocity field and the temperatures distribution is to be taken into account by the control system, a direct or indirect measurement of the temperature in the occupancy zone is needed. The purpose of this study is to control the temperature in the occupancy zone by integrating a low order model into a feedback control loop.
The effect of shading in reducing the energy consumptionof office buildings in Athens is investigated in this article. The aim of this paper is to demonstrate the role of shading devices in the improvement of energy efficiencyof urban buildings especially in Southern Europe.The first phase of research consisted of detailed data collection from 10 office buildings in the region of Athens, employing questionnaires, in-situ visits as well as interviews.
This paper presents a comparison of the characteristics of the energy demand for London, UK and Athens, Greece and explores its relationship with both climate and non-climate related factors. Year-to-year trends for both cities are identified, associated mainly with economic, social and demographic factors. In addition, several other effects such as weekly and holiday effects, unrelated to weather conditions are detected and are examined in comparison for the two cities.
Compact Fluorescent Lightbulbs (CFL’s) use less energy than standard GLS lightbulbs, last longer, are widely available and cost less than ever before. They have also been issued free to households over a number of years through funding provided by the ECC
This paper describes the current Welsh housing stock with a view to assessing the range of existing propertiesin terms of age, construction type and the implicationsfor mechanical heating and cooling of spaces. This work forms part of a larger project that will also involve the development of a series of computer models based on these findings, as well as the design, installation and performance monitoring of a domestic scale solar absorptioncooling system.
This project refers to the study and analysis of a central region of the city of Heraklion in Crete and the proposal of an installation of a light metal construction, aiming at the improvement of comfort conditions of the users of the region.
Energy savings inside buildings require a comprehensivedesign approach to balance bioclimatic strategies with the use of active systems.A climatic responsive building aims to mediate externalagents both to reduce climate loads and to create a healthy and comfortable indoor environment.The sensitive approach to comfort gives nowadays more chances to implement passive strategies and especially the use of natural ventilation.The residential settlement in Pieve di Cento is made with a general Masterplan designed according to sustainableprinciples.
By the new General plan by 2025 in St.-Petersburg it is planned to construct 130 million ??. M of the real estate (for comparison: now in city nearby 140 million ??.). From them nearby 50 million ??. The m is allocatedunder apartment houses, 30 million ??. M - under objects of socially-business purpose (hospital, school, hotel and trading complexes). Besides it is supposed to reconstruct 25 million ??. M industrial ????????and to add to the city real estate 25-30 million more ??. M due to development of an engineering infrastructure.
Looking for the energy efficiency improvement of the buildings, some countries are developing programs for the new or existent buildings to be more efficient. In Brazil, the research is to meet a very recently quality stamp, that is taking care to reduce wastes from the governmental public domain. This article proposes the analysis between the ?glass and wall surface temperatures and increase of classrooms radiance temperature, at Campinas City So Paulo State. For this methodology is adopted the Artificial Neural Network to simulate the variables.
Nowadays in view of the growing expectation of qualityurban spaces, planners, architects and developers concern about urban microclimate in the process of urban development. Under this context, the concept of urban climatic map (UCMap) has been introduced. UCMap is a tool for translating climatic knowledge into urban planning process. It can help urban planning professionals to understand and evaluate the effect of urban climatic issues on planning decision.
