On Site Monitoring of a Solar Boiler System: Energy Efficiency and Economy

Active solar heating was a favorite topic after the first energy crisis. Usage for space heating, however,proved to be completely uneconomic. Domestic hot water systems, instead, retained attention. Theycan be used year-around and have a much larger share in the hot water energy bill than space heatingsystems have in the heating bill. Of course, in the past, energy use for domestic hot water wasonly a fraction of the energy needed for space heating.

Field Test of Methodology to Produce Building Energy Certificates Based on Operational Ratings

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

Designing of a Guarded Hot Box

In 1997 several countries ratified the Kyoto protocol and so engage themselves to take into accountthe global warming, promote the sustainable development and act in order to reduce emission ofgreenhouse gases. Within this context, energy in buildings is known to be one of the first greenhousegases emitting sector. Consequently, determination of steady-state thermal transmission properties foreach kind of faade components becomes necessary in order to evaluate accurately energy loss, todevelop and enhance new products.

CREATION OF A SUSTAINABLE NETWORKING ENVIRONMENT FOR RESEARCH ACTIONS ON THE ECO PERFORMANCE OF BUILDINGS

The European Research Area (ERA) in the field of energy in buildings continues to develop dynamically in response to both the market needs and to the ongoing technological and legislative developments. Various networking mechanisms can be applied by key actors in the field to enhance access to research activities and increase the coherence of the scientific community: one such mechanism was formulated in the early 90s by the grouping of research actors from the PASSYS and PASSYS II research and technical development projects funded in part by the European Commission.

EVALUATION OF THE IMPACT OF NETWORKING ACTIVITIES ON THE QUALITY OF RESULTS OBTAINED WHEN APPLYING SYSTEM IDENTIFICATION TECHNIQUES TO IN-SITU MEASUREMENTS FOR ASSESSING ENERGY PERFORMANCE OF BUILDING COMPONENTS

The application of system identification techniques to the energy performance of buildings and building components requires a very high level of knowledge of physical and mathematical processes. This factor, combined with the quality of the data, the description of the monitoring environment and procedure, together with the experience of the user of the analysis software itself, can end up in varying results from different users when applying different models and software packages.

THE TRANSPARENCY AND REPEATABILITY OF BUILDING ENERGY PERFORMANCE CERTIFICATION

The European Union’s (EU) Energy Performance of Buildings Directive (EPBD) aims to increase the energy performance (EP) of buildings by requiring EU Member States to develop an EP calculation methodology and to certify the EP of their buildings. Dynamic s

Quality Assurance of Solar Ventilated Facade and Mixing Chamber of the Moravian Metropolitan Library

The objective of this paper is to present long time monitoring and post occupancy evaluation of theMoravian Metropolitan Library with the ventilated solar faade used for space heating and with mixing chamber for cooling with the forced ventilation. In consequences of new requirements from the EU Energy Performance of Building Directives 2002/91/EC and changing Czech building regulations is necessary support collective research effort on quality assurance and standardization on solar components and installations in buildings.

IQ-test: Improving quality in outdoor thermal testing

PASLINK is the grouping of 14 European research institutes involved in the performance assessment of the thermal and solar characteristics of building components under real climate conditions. Most of the members are performing semi-standardised tests using the PASSYS/PASLINK test cells. IQ-TEST is the European thematic network project aiming at further developing common quality procedures for testing, calibration, data gathering, cleaning and analysis, interpretation of test results and scaling/replication to real buildings, maintenance of test infrastructure.

Renewable Energies in Energy Performance: Calculation for Buildings

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.

Promoting renewable energy in building regulations: Confronting theory and practice

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.
