AIVC defines smart ventilation as a process to continually adjust the ventilation system of a building in order to provide the desired Indoor Air Quality (IAQ) benefits while minimizing energy consumption, utility bills and other non-IAQ costs (thermal discomfort, noise, etc.). Smart ventilation responds to one or more of the following: building occupancy, outdoor conditions, electricity grid needs, operation of other building systems, direct sensing of contaminants.

Work performed so far in the field of ductwork airtightness has shown that it may lead to important energy losses and increased fan energy use. Nevertheless, a recent survey has shown that ductwork airtightness does not seem to be taken into account (neither in regulation nor in energy performance programmes) in most European countries. Progress is therefore needed to better understand the impact of ductwork airtightness on energy use (fan, cooling and heating) and indoor air quality.

Over the years, different approaches and indices have been used to define indoor air quality. The most frequently used, recognised by the public, and equated with indoor air quality are, of course, ventilation rate and concentration of carbon dioxide. Other approaches define the levels of dissatisfaction with acceptability of indoor air quality, as expressed by the building occupants. At some point in time, the total concentration of airborne volatile organic compounds was proposed, as well.

The BUILD UP portal for energy efficient buildings is holding an online webstreamed event to mark the launch of the improved website.
Expert speakers will present the findings of the Concerted Action EPBD. This is the forum for 28 European Member States plus Norway to exchange best practice on implementing the Energy Performance of Buildings Directive in their countries.

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.

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.
