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

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

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.

According to the Article 6 of the 2002/91/EC – EP “when buildings with a total useful floor area over 1000 m2 undergo major renovation their energy performance is upgraded in order to meet minimum requirements ….” which should be derived “…in accordance w

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.

The combined heat, cooling and power production (CHCP) is one of the most interesting methods toincrease the system global efficiency by supplying electric and thermal power needs both in winter andin summer, and at the same time reducing CO2 emissions.Global efficiency increase is related to the use of waste heat which can be also used to producecooling energy by means of a absorption chillers.A CHCP programme is planned in a specific area in the University City of the University of Rome LaSapienza (approximately 1000.000 cubic meter and an energy bill of some 10 M) and it consists of agas

In this paper, a study of the energy performance in Singapore’s hotel industry is reported. Energy consumption data and other pertinent information were collected from 29 quality hotels through a national survey. Building features and operational characte

In this past decade, glazed façades use in new buildings has soared. Some of these façades, called "double skin façades", are made of internal and external glazing. As indicated by its name, "double skin façades" are a special type of envelope which air s

Indoor humidity is an important parameter influencing the occupants’ perception of indoor air quality, and is also a cause of harmful processes that may occur on surfaces of materials, such as cracking of walls or microbiological growth. Building material

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.
