This project aimed at developing a methodology to help the Local Authorities and the town managersto carry out suitable policies in order to save energy and promote the use of renewable energies. Thismethodology will be useful too for the civil servants in charge of following and assessing the localactions granted by the Regional Authorities.
In the context of pressing and frequently conflicting environmental, economic and social policyobjectives, energy efficiency investment is repeatedly found to be a cost-effective and reconcilablecomponent of energy policies. High-rise residential buildings are a particularly salient issue in thisregard as their poor energy efficiency is regarded as a moderate to major problem by 18 out of 27housing ministries respondent to a Europe-wide survey.
Recent studies predict a dramatic increase of cooling energy demand in Europe, despite the availableknowledge and technologies of passive cooling. The international project KeepCool addressed thisgap, searching for intelligent ways to promote the market penetration of passive cooling technologiesand a new definition of sustainable summer comfort based on the adaptive comfort model. The projecttailored the available information into a toolkit for building owners, planners and building users.
This paper aims to report the solar and thermal data for various common and innovative materialsused in outdoor urban applications. The tested materials include various types of coatings, tiles andasphalt pavement. In the framework of this research, the spectral reflectance and the emissivity of thematerials were measured using a UV/VIS/NIR spectrophotometer fitted with an integrating sphere andan emissometer. The solar reflectance of the samples was calculated.
Building Integrated Photovoltaic (BiPV) systems is a “Zero Land and Zero Water” power systems as it neither consume any additional land nor consume any water. Moreover, introduction of BiPV systems reduces the thermal load of the building. The integrated
This paper presents the application of multi-inputs single-output (MISO) models to estimate thethermophysicals parameters of a building. ARARMAX, Box-Jenkins and the general MISO models areused to identify the U value, the time constant and the equivalent solar surface of the building.Optimization-based prediction error method (PEM) algorithm is used to estimate model parameters.This approach has been tested to analyze a passive solar house in Tunis. The identified parameterswere compared to theoretical values; good results have been obtained for the tested building.
There is an obvious and indisputable need for an increase in the efficiency of energy utilisation inbuildings. Until now, so-called energy saving measures and analyses of energy flows in buildings havecommonly been based on the energy conservation principle, the first law of thermodynamics.
Within the context of an energy performance regulation, it is essential to take the transmission lossesinto account. If building details are not well designed or carried out, thermal bridges can substantiallyincrease the transmission losses. Though, the physical principles for evaluating thermal bridges arewell known and covered by European standards.
The EPLabel project is developing a ‘graduated response’ to address the EPBD Article 7.3 requirement for ‘Public Buildings’ over 1,000 m² to display an Energy Performance Certificate prominently. The idea is that assessments can be at different levels of
The EPLabel project addresses the EU Energy Performance of Buildings Directive (EPBD) Article 7.3: the requirement for ‘Public Buildings’ over 1,000 m² to display an Energy Certificate prominently, OJEC (2003)[1] and is supported by the EC’s Intelligent E
