Use of IEA-SHC Task 21 C Benchmarks to assess performance of lightscape 3.2 in daylight calculations | 2002 | English
Prediction of the impact of building design parameters on the thermal behaviour of a building in the early design stage | 2002 | English
The thermal performance of a building depends on a number of building design parameters. Development of ‘energy efficient building concepts’ therefore requires insight in the here mentioned interrelation.
Advanced daylighting strategies and systems can considerably reduce a building’s electricity consumption and also significantly improve the quality of light in an indoor environment.
Impact of the control of shading devices on the thermal behaviour of large highly-glazed spaces | 2002 | English
Evidence suggests that a significant number of large highly-glazed spaces have major design flaws that lead to energy wastage and discomfort.
In effective use of solar energy and calculation of the heat load of buildings for energy conservation, the actualstate meteorological data are indispensable.
Determination of places in the great Athens area where the heat island effect is observed | 2002 | English
The main purpose of the present study is to define places in the major Athens area where the heat island effect occurs. Several important climatic parameters are examined in combination with the application of various statistical tests.
Luminous performance and energy savings of a solar tracking mirror system for daylighting | 2002 | English
The aim of the present study is the proposal of a novel tracking mirror system for the daylighting of deep interior spaces, such as commercial buildings, underground railway stations, parkings, etc..
External shadings and glazing materials as passive systems to improve energy consumption and indoor comfort in office buildings | 2002 | English
External shading systems, window systems and light control systems try to reach the indoor comfort and energy saving by approaches, that are different in complexity, costs and results; besides a good coordination among them could produce better pe
HipHip - Fostering market penetration of PV systems integrated in buildings in Europe | 2002 | English
The general objective of the Hip-Hip project, partly funded by the EC, is to foster market penetration of GC-PV systems integrated in buildings in Europe by removing technical and non technical barriers as well as developing new PV products for th
During the design process of heating systems, the designer must analyse various factors in order to determine the best design options.
Radiative cooling systems by means of nocturnal longwave radiation have captured the attention of today’s specialists involved in the construction building process.
Classification of the IDMP data of Kyoto into Kittler-Perez model of sky luminance distribution | 2002 | English
The purpose of this paper is to validate Kittler-Perez model of classification of sky luminance distribution about the IDMP data in Kyoto Japan.
Hydronic radiator heating with thermostatic valves: Improves thermal comfort or upgrades efficiency? | 2002 | English
Energy performance standardisation evaluates all measures at the building and building services level that improve energy efficiency. Thermostatic valves are one of the choices, which are considered.
The energy consumption of consumer electronics is steadily increasing. In the 1992-1996 period its energy consumption has increased by roughly 50%.
Passive cooling techniques for buildings. Potential of use within venezuela's climatic zones | 2002 | English
The current paper presents the first outcome of a study dealing with thermal quality of buildings in a context of rationalized energy spending.
SERRAGLAZE is a breakthrough daylighting system designed to be incorporated into the primary glazing of normal sidelit rooms to save energy and enhance comfort.The paper describes the design, construction and optical properties of the plastic SERR
Experimental Assessment of the Effects of Spacer Bar Design on the Condensation Resistance of Insulating Glass Units | 2002 | English
Experimental and analytical assessment of three types of spacer bars used in making insulated glass (IG) units were performed and reported earlier, Elmahdy et al (1993).
Information in the UK Climate Change Programme suggests that carbon savings in the domestic sector from end-use efficiency improvements could amount to some 4.7MtC/yr in 2010, based on allowances for improvements to the building regulations, resid
A review of the solar water heating equations in the BRE Domestic Energy Model was carried out using data from a recent monitoring project. The savings predicted by the model did not match the test data well, so improved equations were devised.
