In year 2000 the Valby PV plan was launched introducing 30 MWp PV (300.000 m²) aiming at 15% BIPV for electricity use in year 2025.

GREEN SOLAR CITIES – EU Concerto project meeting, Salzburg 16-17 April 2013 PV-implementation in Valby and Copenhagen An important background of the PV implementation plan in Valby was to ensure that PV would be a positive element in the city development

With the improved demands in the EU building directive from 2010 aiming at a nearly zero energy standard for new build already from 2018 in public buildings and in 2020 for all buildings together with demands towards the EU member states to create a similar standard for existing buildings, it is now a challenge to create a whole new basis of energy efficient building design in Europe and show how local use of renewable energy can be part of the solution.

At the same time the city of Copenhagen has an ambition to become the first carbon neutral capital in 2025. Due to this it is now accepted to have PV integration towards street areas.

Extensive retrofitting of buildings, reorganisation of the energy supply and change in transport habits are some of many initiatives the City of Copenhagen will implement in order to become carbon neutral by 2025. With the climate plan, the Danish capital combines growth, development and higher quality of life with a reduction in Carbon emissions of around 1.16 million tons.

The EU-Concerto project, Green Solar Cities (www.greensolarcities.com) have since 2007 included a cooperation between Valby in Copenhagen and Salzburg in Austria. EU funding is here utilised as a strong support for the large scale PV implementation plan in Valby.

Concerning the PV installation at “Damhusåen” waste water treatment plant in Valby, there are huge prospects of the here used approach since waste water treatment plants use 8% of all electricity use in Denmark and even more of electricity use in Valby.

At Hyldespjældet in near Copenhagen in Denmark, the first zero energy housing renovation project in Denmark was realised in year 2009. Due to large scale renovation plans for 3000 – 5000 concrete housing units in Albertslund during the next 5 years, this was a very important project, which also received the Energy Globe price for Denmark.

In Hyldespjældet a prefabricated so-called Solar Prism was placed on the flat roof and includes all installation elements.

Above is shown an indication from early 2011 of the historic and expected development of the economy for PV systems in Denmark towards year 2020. By September 2012 the PV costs of 2020 has almost been achieved, and around 100 new PV installations especially for one- family houses were made every day in Denmark, based on the netmetering scheme which leads to a payback time around 10 years.

There is a need for a new approach to energy efficient housing renovation showing how renewables can be introduced together with an optimised energy supply. The Active House Specification can be useful here.

GREEN SOLAR CITIES – EU Concerto project meeting, Salzburg 16-17 April 2013 PV-implementation in Valby and Copenhagen

In the Active House Specifications there is a demand for energy monitoring, verification and follow up. This is new compared to the situation in Denmark today where there is a lot of focus on good calculation procedures, but, like in most other countries, no link to what the actual energy use will be in practice in realised building projects.

A good possibility here could be to introduce the same demands for “verification” of all new building projects within a two year period, which already have been introduced in Sweden.

By the end of 2011 a very interesting PV project with 45 kWp PV (approx. 360 m²) for the 90 apartments at Søpassagen in Copenhagen has been realised. This is the first BIPV installation in Copenhagen which has been allowed even though it can be seen from the street area, and the background for this new policy is the climate plan of Copenhagen from 2009 which aims at CO2 neutrality by year 2025.

The Søpassagen project has been realised in connection to a Cenergia initiated campaign called PV Cities which aims at promoting best practice BIPV applications in Denmark. Besides Cenergia the company Solarvent has been the main actor in the project.
