One of the prerequisites for the design of buildings that make good use of daylight for internal illumination is a knowledge of the daylight climate in the place where the building is to be situated. The amount of light likely to enter a building is often quantified using Daylight Factor, the ratio of internal to external illuminance, which can be measured by taking some internal and external readings with a luxmeter. A luxmeter is a photometric device that uses a photocell with V-? and cosine correction.
Investigationofventilationmeasurement methodwas carried out in a full-scale test house. The aim of this study was to examine the ventilation rate via human expiration. The adopted method is able to measure multi-zone airflow rates. Airflow rate between rooms was monitoredand the outdoor airflow rate was measured by using the constant concentration tracer gases. The rate of outdoor airflow entering the house and the airflow rate between the rooms were estimated by the ventilation measurement method via human expiration based on system identification theory.
Urban development is unavoidable as the result of country’s economic growth. Without a careful planning, a city may cause environment destruction. Singapore is known to have the best environmental quality in the world. However, in the previous research on
In the previous study, it was found that urban heat island intensity in National University of Singapore (NUS) campusas high as 4oC at around 13:00. It is also concluded that the presence of dense greenery in NUS environment is very important in keeping low ambient temperature.National University of Singapore has announced its new master plan in 2005, entitled NUS Master Plan 2005. Many new buildings will be built and in some areas existinggreenery will be removed.
The objective of this work is to compare the thermal behaviorof two systems of beam ceilings used in the Collegeof Architecture of the Independent University of Chiapas - Mexico. The beam ceiling base (show room) is of reinforced concrete with 10 (ten) centimeters of thickness that will be reference for comparative degree how much to the internal temperature of air in relation the construction covered with developed technology of in the College of Architecture of the UNACH that has water blade of 15 (fifteen) centimeters of thickness.
The European research project “EULEB – European high quality Low Energy Buildings” intends to provide information about good examples of energy efficient buildings in use, in order to reduce prejudices and lack of knowledge of many key actors of the build
Illuminance and daylight availability are important parametersin daylighting design for passive, low energy architecture. In Malaysia, the only climatic parameter that can be used for determining daylight availability is global solar irradiation, which is measured at major meteorologicalstations around the country. However, it is possible to estimate the global illuminance from global solar irradiation data if the global luminous efficacy is known.
This paper concentrates on the results of sustainability caused by Courtyard as a climatic element in Iranian traditionalarchitecture of cold regions. Traditional architectureof Iran is perceived sustainable for having sustainablefeatures. It is able to response to environmental problems from a long period. Its features are based on climatic factors as well as local construction materials of cold regions and Courtyard (hayate- markazi) is one of this features .Courtyard as one of the determining and organizing factor of traditional architecture in cold regions involves varies aspects.
“Energy Towers” is the name of a technology which was developed at the Technion--Israel Institute of Technology, to produce electricity in arid lands, taking its predicament - a lot of hot dry air - and turning it into an asset. “EnergyTowers” is an econo
The energy rehabilitation of listed buildings is of great importance as they are many limitations of the possibletechnical interventions. The paper presents the outcomesof a study concerning the possible interventions in an existing building focusing in the minimization of the energy consumption and the achievement of the desirablethermal and visual comfort.The building is located in the centre of the city of Athens,Greece with total heated area of approximately 896m2. The building has areas with different use, such as offices, seminar room, and restaurant.
