How does the German “Mieterstromgesetz” [Tenant Electricity Law] work?

In the end of July 2017, the German law on the promotion of tenant electricity (Gesetz zur Förderung von Mieterstrom) entered into force. With this law, tenants shall benefit from the energy transition. In fact, the law promotes landlords...

What is meant with “Rebound Effect”?

Efficiency measures at the building envelope and the building services systems decrease the operational costs of buildings. But reduced costs can lead to changes in the behaviour of the building users. They consume more energy and parts of...

Are there EU funded projects – schemes, based on nanomaterials in the construction industry?

The list that follows provides brief information on EU funded projects and clusters in the field of nanomaterials:   ADAPTIWALL project used multi-functional light-weight wall panel based on adaptive insulation and nanomaterials for...

Which nanomaterials are most commonly used for photocatalytic applications?

Titania (TiO2) is suitable for several environmental applications such as air purifier, waste water treatment cleaning, water disinfection and photo-induced hydrophilic coating with self-cleaning properties. It can be incorporated in bulk...

What are the critical parameters in the use of nanomaterials in the building sector?

The selection of the appropriate matrix is of importance since it can affect the effectiveness of nanomaterials, or even react in such a way that unwanted by-products may be produced.   The presence of dissolved oxygen in the liquid...

What are the uses of Photocatalysis in the building environment?

There are many examples of photocatalysts aimed at reducing urban depollution applied on photocatalytic pavements. Titanium dioxide (Titania) is being explored as a component, but the correct method of applying photocatalysts in pavements...

What are the important factors for the photocatalytic performance?

The size of the nanoparticles is an important factor, when it comes to the photocatalytic performance. Nanomaterials with smaller particles are expected to provide better photocatalytic activity.   In order to enhance the photocatalytic...

Are there examples of photocatalytic applications in the building industry?

Self-cleaning/photocatalytic properties are known since the 1960s, but they have only recently been widely exploited. The first application was on the church ‘‘Dives in Misericordia” in Rome. It is composed of 346 self-cleaning concrete...

What is photocatalysis and how does it work?

Photocatalysis is the activity occurring when a light source interacts with the surface of semiconductor materials, the so called photocatalysts. During this process, there must be at least two simultaneous reactions occurring, oxidation...

Where can I find information about best practices on innovative financing for energy efficiency?

Previous experience of the Member States has shown that conventional financing is not enough for meeting their energy and environmental targets and access to attractive and adequate financing products from the market is needed.   Public...

What kind of innovative financing mechanisms have been invented so far?

For many years now Member States have engaged in energy transition. This long experience has shown that conventional financing is not enough and financing sustainable energy measures remains a great challenge. For this reason, access to...

What is the Juncker Plan?

The Juncker Plan is also known as The Investment Plan for Europe.   It was proposed by the European Commission in November 2014, following the European Council's call in June 2014 for the low levels of investment in the EU to be...

What are the main types of procurement in the construction industry?

In the ZERO-PLUS project report “Analysis of the market potential within the EU28 for “nearly zero-energy” buildings constructed using the concepts developed in the project” the main types of procurement in the construction industry are...

How can costs be reduced from designing for settlement level instead of building level?

The benefits of the analysis at the settlement level arise not only from the larger scale compared to single buildings, but also, importantly, from looking at a system of houses with their interactions. This means, for instance, cost...

What are the drivers and barriers for the construction of residential NZE buildings and settlements?

In the ZERO-PLUS project report “Market analysis of trends in the construction of residential highly energy performing buildings” a significant amount of information on barriers and drivers for the construction of highly energy efficient...

What is the Western Balkans Investment Framework?

  The Western Balkans Investment Framework (WBIF) was launched in 2009 by a coalition of institutions, donor countries and financial organisations. It aims to help the Western Balkan countries, (Albania, Bosnia and Herzegovina, Kosovo,...

How to support energy efficiency in Western Balkans?

Energy saving has been identified as strategic priority to ease energy intensity in the six countries (WB6) of the Western Balkans. The WB6 countries are members of the Energy Community, whose mission is to extend the EU internal energy...

Is there a difference between “shall” and “should” in the EPBD?

In the Energy Performance for Buildings Directive (EPBD), “shall” is used in article 9, whereas “should” is used in article 2:   Article 9 of the EPBD states that: “Member States shall ensure that by 31 December 2020, all new buildings are...
