Ventilative cooling reduces overheating, improves summer comfort and decreases cooling loads. It is therefore one of the most efficient ways to improve summer comfort. Conditions on site, thermal inertia, solar control and other constraints have an impact on the choice of the system and its design. The overall performance is linked to good sizing, design, correct usage of thermal storage, and last but not least a correct control, commissioning and maintenance.

Building airtightness: a critical review of testing, reporting and quality schemes in 10 countries
Post date: 27 Apr 2017
Building’s Energy Performance Certificates (EPCs) are expected to correctly inform prospective buyers and tenants, to encourage them to invest in energy efficiency in buildings. Progressively, this should lead to a positive relationship between a property's energy rating and its market value.

Effective implementation of the Energy Performance of Buildings Directive in practice implies, among other things, high quality construction works such that a completed building’s energy performance is as planned. It also requires national frameworks which monitor and enforce compliance with energy regulations. This article provides an overview of quality and compliance issues relevant to the EPBD, as well as interesting highlights from the Member States’ experience.

An analysis of the outcomes of the national dialogue in 26 countries between the competent authorities implementing the Energy Performance of Buildings Directive represented in the Concerted Action EPBD and the BUILD UP Skills consortia working on improving the skills and qualifications of buildings workers.
Post date: 30 May 2014
Concerted Action EPBD and BUILD UP Skills joined forces and engaged in national dialogue in order to identify and highlight priority measures, both from the regulatory and the skills development perspective, for the transition faced by the building sector towards NZEB. The analysis of the outcomes of the national dialogue in 26 countries is presented in a full and a summary report available at the CA EPBD website.

The implementation of the EPBD recast puts increasing pressure on the market to achieve better building and ductwork airtightness: for most European climates and countries, good airtightness levels are necessary to achieve nearly zero-energy buildings.
You will learn about legislative drivers that have brought to light new concerns and stimulated new initiatives. We will discuss recent trends in European regulations as well as field studies supporting the development of competent testing schemes.

Since the oil crisis of the seventies, the interest given to buildings physics, indoor climate and energy use has strongly increased. The building envelope and HVAC systems in modern buildings are often completely different from those typically found in buildings of the sixties and seventies. In general, we often consider the quality of today’s buildings substantially higher. To what extent is this impression of improved quality fact or fiction? Is it valid for all technologies and is there a substantial improvement in quality of the indoor climate?

It is expected that many countries will between 2015 and 2020 have regulations imposing requirements for new buildings which are near-zero energy targets. This has major consequences:Such strategies will for most climates automatically lead to specific attention to building airtightness, including large scale measurements, challenges in terms of design and execution, quality issues, long term performances, ... This is a tremendous challenge.
