Adoption of daylight as an energy efficiency strategy is especially relevant for a climate like Malaysia, as the country experiences long sunshine hours throughoutthe year. An important aspect of effective daylight strategy is the performance of the window in permitting daylight entry. This paper presents a study conducted to account daylight availability in an office interior undervarious fenestration options; namely window-wall-ratio (WWR), glass types and application of external shading devices of varying depth.

This document presents the theoretical study of evaporativecooling designed for the outdoor spaces in the Spanish pavilion of the coming International Exhibition in Zaragoza 2008.

It is a well notorious fact that if you get below the surfaceof the earth a few meters, the temperature tends to be constant and at 8 to 12 degrees, depending on latitude.So, it does not take an architect to appreciate that if you could move outside air through a buried pipe, you could alter its temperature and then move it into a house where it can warm or cool the homes interior.Underground temperatures can be very beneficial in balancingthe thermal comfort of the house.

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.
