This paper discusses the status of standards and regulations concerning performance calculationmethods for renewable energies systems in the built environment. The outcome of a European wideinquiry on this topic, carried out in the frame of the European project on Energy Performance Regulations (EnPeR) will be presented. In addition an overview is given of the renewable energiessystems that are considered under these regulations and the consequences of the new EnergyPerformance Directive.
In urban canyons reflected sunlight can play an important role in the illumination of buildings, particularly in orientations and during times of the day where sunlight is not incident on the windows. Facing buildings provide considerable obstruction to daylight by reducing the skylight contribution and sometimes blocking the access to sunlight. However, reflected sunlight is an important contribution to the internal illuminance of a room and should not be underestimated.
The operation of an outdoor test site requires very substantial efforts with respect to investments, maintenance, calibration and training staff. The existing documents dealing with quality procedures in principle guarantee that a good quality level is achieved at all test sites. This paper describes the existing quality manuals and the software tool PASLINKIT developed in the scope of IQ-TEST Thematic Network to make all this pertinent quality documents more practicable and feasible.
The European Commission has expressed the wish to harmonize energy regulations in the building sector and at the same time has formulated goals for promoting the use of renewable energy sources. This paper studied the possible synergy of these two targets. To make a first step in this research topic renewable energy techniques are considered as environmental innovations for which incentives, being a public good, is dependent on governmental intervention, like energy policy instruments.
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. In the recent past many advanced simulation tools
People employed in building offices have new needs in terms of comfort at the working place. To satisfy these needs, it is necessary that architects check carefully the efficiency of the corresponding new systems that they conceive in order to improve these people working conditions. This study shows that it is possible to optimize the sizing up of the different elements of an office cell front (envelope) containing, in addition to the glass wall, sun-breaker strips and an electrochromic protection. For that purpose, the inverse simulation technique was used thanks to several programs.
The EC funded ‘SmartHomes’ project commenced in 2001 as a 3 year programme. The primary objective is to establish Internet-based energy services and test these within field trials in Sweden, Greece, the Czech Republic and the UK. The tasks include the pro
IQ-Test is a Thematic Network supported by the European Community under the EESD Programme.The objective of IQ-TEST is to further develop common quality procedures for the PASSYS/PASLINK test cell facilities that exist in 12 European countries. This should consolidate thenetwork, integrate the new test sites and strengthen its common approach of support for new product developments in the field of innovative building components.Round robin tests are underway to assess both the inter-site quality of testing and analytical procedures of the participants.
A common architectural feature of curtain wall facades is constituted by a transparent double-glazing unit mounted in front of a recessed interior metal panel. It is typically installed in spandrel areas, where its required to provide to the faade not only surface consistency but also depth.To evaluate condensation risk on this type of envelope element, an experimental program has being carried out on a typical facade panel (Shadow-box) provided by Permasteelisa.
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. The prediction of these improvements requires good models of glazing pro
