Evaluation of the thermal behavior of two systems of ceilings: reinforced concrete and wather layer | 2007 | English
Widely known as urban heat island (UHI) phenomenon, urban air temperatures tend to be higher than rural temperatures,due to the thermal performance of building materials and urban geometry, together with the productionof anthropogenic heat.
A simplified tool for the energy certification of Italian existing dwellings. Comparativeand sensitivity analyses | 2007 | English
The article 6 clause 9 of the Italian Decree Law 192/05, that transposes the European Directive 2002/91/EC on the energy performance of buildings (EPBD), supportsthe definition of simplified methods in order to carry out the energy certification o
The requirements for good indoor air quality and energyefficiency have often been considered to conflict with each other, however, buildings with low energy consumption in Europe seem to have also a lower rate of building related health symptoms.
A convenient coupled simulation method for thermal environment prediction in naturally ventilated buildings | 2007 | English
As both CFD and building simulation have their own limitationsin the thermal prediction of natural ventilation.
Energy towersA renewable energy technology for producing electricity and desalinated water in arid climates | 2007 | English
“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.
The goal of this study was to suggest a low-density typologyfor commercial buildings to be applied in the cultural and climatic context of Athens, Greece, with minimal demand for conventional cooling.
A heat island study of Athens using high-resolution satellite imagery and measurementsof the optical and thermal properties of commonly used building and paving materials | 2007 | English
In this study, high-spatial resolution multispectral satelliteimages collected over the metropolitan Athens area in Greece are used to generate a) a broadband albedo map depicting the albedo spatial variations across the metropolitan area, b) a ve
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.
Five most commonly used single span shapes of greenhousesviz. even-span, uneven-span, vinery, modified arch and quonset type have been selected for comparison.The length, width and height (at the center) is kept same for all the shapes.
Monitoring and simulation of two operational buildings integrating active thermal mass strategies | 2007 | English
Thermal mass can be used in buildings to reduce the need for and dependence on mechanical heating and cooling systems whilst maintaining environmental comfort.
On the relation between the energy and social characteristics of the residential sector | 2007 | English
Social, financial, energy and technical data from about 1110 households have been collected during 2004 in the major Athens area. The sample has been divided in seven income groups and a detailed analysis has been performed.
Building integrated PV water heating and air conditioning in the special hospital of the SPA Rusanda | 2007 | English
Different types of thermal activation of building structuresare increasingly utilized in buildings including BIPV, multifunctional PV facades with controllable daylight/solar gain features and integrating thermal and electrical output.
Daylight and luminaire control in a perimeter zone using an automated venetian blind | 2007 | English
Commercial buildings with large exposed glazed façades require solar shading devices in order to protect occupants from uncomfortable direct glare.
Pressure-drop and energy-saving analysisof TBAB clathrate hydrate slurry as a latent heat transportation media | 2007 | English
The Clathrate Hydrate Slurry (CHS) of Tetra-n-Butyl-Ammonium Bromide (TBAB) comes into being under normal atmosphere when aqueous TBAB solution is cooled to 5-12 . It is a kind of high-density latent-heattransportation medium.
The combination of clay and nanotube carbon as an innovative and sustainable material | 2007 | English
The idea of using one-dimensional fillers as a reinforcingagent is nothing new: straw has been used to reinforcemud bricks since about 4000 BC.
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.
State of the art on macroscopic models for the determination of thin films optical properties | 2007 | English
Optical properties (i.e.
Design aspects and perspectives for solar control of buildings with aesthetic and efficient solar thermal collectors and photovoltaics | 2007 | English
New solar energy systems with efficient energy output and advanced aesthetics have been developed at the University of Patras last 20 years.
Despite the available knowledge about technologies for passive cooling, cooling energy consumption is still increasing in Europe.
