Cost-Effective Requirements Levels for Energy Performance of Buildings in Lebanon

This paper presents the energy and economic analysis used to determine cost effective requirementslevels to the thermal standard for buildings in Lebanon. The heating and cooling energy use fordifferent buildings types (18 buildings) according to the variation of envelop parameters was simulatedfor realistic cooling and heating schedules and five Lebanese climatic zones. Parameters investigatedincluded, construction type, insulation levels, window sizes and solar protection. The energysimulation program VISUAL-DOE.3 was used for the energy use simulations.

Control of the Ep-Regulation in 3 French Regions: Approach and Preliminary Results on 29 Buildings

This paper focuses on energy performance compliance checks to the French EP-regulation RT 2000 and the way they are performed in Rhône-Alpes, Burgundy, and Franche-Comté. It gives an overview of the approach developed and used which consists in collecting

CO2 Emission and Energy Saving Potential through Correct Pipe Insulation of Space Heating and Domestic Hot Water Distribution Systems in the New and Existing Buildings

In March 2003 a “CO2 - Saving Potential when using Pipe Insulation” study [1], sponsored by Armacell - worldwide producer of flexible pipe insulation products, was published by the Centre for Environmentally Sustainable Buildings (ZUB) in Kassel. The aim

Cluster Analysis in Energy Classification of School Buildings

The present paper presents the results of the application of cluster analysis in the energy rating ofschool buildings. A complete program on energy and environmental quality of school buildings wasundertaken by NKUA in collaboration with the School Authority of Greece. The research was based onthe participation of 320 schools of secondary education from all the prefectures of Greece.

Assessment of the Potential of Cool Materials to Contribute to the Mitigation of the Heat Island Effect in Athens

The mitigation of the heat island effect can be achieved by the use of cool materials that arecharacterized by high solar reflectance and infrared emittance values. Several types of cool coatings,both commercially available and prototype ones have been tested. Their spectral reflectance, infraredemittance and surface temperature measurements reveal that these materials can be classified ascool materials with the ability to maintain lower surface temperatures. Cool materials can be used onbuildings (roofs and walls) and other surfaces of the urban environment.

Assessment of Quality of Built Environment. A Case Study in North of Italy

The paper describes results of a Preliminary Study for the Plan of Quality of Living (PSPQL) of a townin the hinterland of Milan, conducted by an interdisciplinary group of researchers, involving alsofacilitators, town councillors, administrators, technicians and citizens. Main aim of the work is theevaluation of the most sustainable actions to be taken for improving conditions of living. A bottom-upand participative approach has been followed.

Assessment of Heat and Mass Transfers in Building Porous Materials

Heat and mass transfers in building materials influence the thermal properties and performances ofthe materials more especially as they are porous. This paper deals with the case of various porousbuilding materials (Aerated Autoclaved Concrete, Hemp Concrete and Vertically Perforated Brick)studied by an experimental approach. A cell of exchange makes it possible to impose on a sample,gradients of temperature and relative humidity variables as function of time. The performances ofthese materials are thus deduced from the evolution of T and %RH in several positions.

Assessing Energy Saving Potential of a Public Building Stock in Relation to the National Implementation of the Energy Performance of Buildings Directive

At present 95% of energy consumption for heating, domestic hot water, air conditioning, lighting andventilation in Europe are related to buildings built before 1980.

Anticipated Solutions to Reduce Electricity Demand during Peak Period

Researchers and practitioners have proposed a variety of solutions to reduce electricity consumptionand curtail peak demand.

An Intermodel Comparison of DDS and Daysim Daylight Coefficient Models

This paper presents the results of a Radiance-based intermodel comparison between the validatedDaysim daylight coefficient model and a new standard model for dynamic daylighting simulations (DDS).The new model offers independence from site location and orientation, estimation techniques andsimulation applications. The standard data can be used for dedicated daylighting analysis or for integratedbuilding energy/daylighting simulation. Results show that DDS outperforms Daysim, notably in caseswhere sensors are subjected to sudden changes in solar exposure, e.g.
