Webinars

Ventilative cooling–i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces –can be very effective to reduce the cooling energy demand in buildings in summer or mid-season conditions.

This webinar is part of a broader series focusing on ventilative cooling in energy performance, within the context of compliance with building regulations in several countries.

The QUALICHeCK-TightVent webinar: "Building airtightness and initiatives to improve the quality of the works" was held on Tuesday 12 January, 10:00-11:30 (Brussels time). The objective of this webinar was to give background information on selected initiatives to improve the quality of the works with respect to building airtightness.

The programme included 4 presentations of 20 minutes as follows:

Ventilative cooling–i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces –can be very effective to reduce the cooling energy demand in buildings in summer or mid-season conditions.

The principal objective of this webinar series is to give the status, needs, and perspectives on developments to consider ventilative cooling in energy performance assessment methods in several countries.

This first webinar will focus on the developments in Austria, Denmark and France.

Description

The second conference on compliance and quality of works for energy efficiency in buildings will be organised in Brussels on 4 September 2015.

The Energy Performance of Buildings Directive recast introduced in 2010 two important articles requiring Member States to implement independent control systems for the Energy Performance Certificates (article 18) and penalties in case of non-compliance (article 27). Although often overlooked, these aspects are essential to meet the overall goal of the EPBD, i.e., to generalise Nearly Zero-Energy Buildings (NZEB) in practice.

The Energy Performance of Buildings Directive recast gives ambitious goals for the building sector to reduce energy use as well as greenhouse gas emissions. It requires member states to engage in the generalization of Nearly Zero-Energy Buildings and to set up the necessary actions to support the mandatory availability of Energy Performance Certificates (EPC), both for new and existing buildings.

The objectives of this webinar are:

Over the past few years, there has been an increasing number of airtightness tests performed in Europe either for specific high-performance buildings programmes or for a wide range of buildings in regulatory contexts. This has led to the development of competent tester schemes to contain potential legal and competition issues.

The objective of this webinar was to give information on the status and trends in airtightness testing in Denmark, Ireland, and Sweden including the details and feedback on competent tester schemes.

Ventilative cooling is the use of natural or mechanical ventilation strategies to cool indoor spaces. It can significantly reduce the cooling energy demand in summer or mid-season conditions. Therefore, ventilative cooling is increasingly common in NZEBs.

This BUILD UP Web Seminar addressed the following:

Because ventilation represents a very substantial part of the space conditioning energy needs, there is a growing interest in European member states for Demand-Controlled Ventilation (DCV), i.e., for strategies and systems to control the amount of air provided indoors depending on the actual needs.

The objective of this webinar is to give an overview of the approaches developed in 4 European countries to consider these systems consistently with European standards, in particular, in an energy performance regulation context. 

Over the past few years, there has been an increasing number of airtightness tests performed in Europe either for specific high performance buildings programmes or for a wide range of buildings in regulatory contexts. This has led to the development of competent tester schemes to contain potential legal and competition issues.

The objective of this webinar was to give information on the status and trends in airtightness testing in Germany, the Czech Republic and France including the details and feedback on competent tester schemes.
