  4. Project description Purpose In the BIPV Quality Cities project there will be demonstrated high quality PV systems for municipal and housing association owned buildings in relation to a large investment programme organised with support of the EU-Elena programme, which at present does not have building integrated PV as a priority. The project aims to ensure a documentation of BIPV Quality and online solar results for at least 3,85 MWp PV investments which includes at least 25 municipalities, involved in 20 MWp total investments (equal to approx.300 mio. DKK), and leading housing associations. Besides there is a similar focus for a limited number of larger schemes and one family housing units in connection to cooperation with frontrunner municipalities, Albertslund, Copenhagen, Hørsholm and Roskilde. Project results are to be facilitated by help of a common Solar Watch platform on the internet, where there is also a link to online monitoring results. In the BIPV Quality Cities project the total amount of PV systems with special focus on BIPV Quality, Solar Watch online monitoring and electricity savings will amount to 3.850 kWp of which 1.750 kWp is with the 25 cities from Region Zeeland and Region Copenhagen, 1.250 kWp is with housing associations, 800 kWp is large PV systems without netmetering and finally 50 kWp is for one family houses. Albertslund municipality will together with Copenhagen, Hørsholm and Roskilde be involved as frontrunner cities also with a special focus on optimised PV systems for housing association renovation and commercial buildings respectively.

  5. Examples of innovative BIPV technologies In the BIPV Quality Cities project it is the idea to introduce a number of innovative best practice BIPV solutions towards the partners e.g. in connection to sketch design projects, followed up by actual demonstration projects. An important example here is the general need to introduce actual “Active Roofs” where it is the PV modules that is actually the climate shield. From investment, maintenance and durability point of use it is important to have good system solutions of this type, although the normal choice is just to mount PV modules onto an existing roof without thinking so much about the long-time maintenance plans. Another interesting possibility is to investigate the benefits of working with east / west oriented PV systems as an alternative to south oriented PV systems. In Germany this solution has recently become quite popular even though the yearly PV production typically will be 15 % lower than compared with south oriented PV systems. But for a certain area of roof or piece of land you can actually utilise nearby a double as high PV capacity since the problem of shadows becomes nearly negligible. Besides the installation costs are according to German experiences typically 25 % lower for large systems and the inverter costs is 30 % lower together with a more equal PV production during the day. This is certainly interesting prospects, which will be investigated further and demonstrated in the BIPV Quality Cities project.

  6. Example of east/west oriented PV solution in a German roof. Typical example of east/west oriented PV solution on a flat roof with a high utilisation of the available space

  7. The ForskVE, PV-Cities 2012 supported BIPV project in Copenhagen, Søpassagen, has been used by Copenhagen municipality as cover of its small guide on PV implementation.

  8. Illustration of the PV-plan for Valby, with the aim to cover 15% of all electricity use in year 2025 by 30 MWp PV (approx. 300.000 m2 PV)

  9. “Solar Prism” with BIPV used as a prefabricated installation element for the Hyldespjældet test house realised in Albertslund in 2009. Cost optimised PV roofs in combination with VELUX roof windows for a private housing unit in Albertslund (Degnehusene 26). Here is shown a more costly solution where the PV is in flush with the VELUX windows and a more cost optimised solution which is still architecturally optimised.

  16. Ifølge EU’s bygningsdirektiv skal alle nye offentlige bygninger udføres i en næsten 0-energi standard fra år 2018. Og fra år 2020 vil dette gælde alle bygninger, samtidigt med at medlemsstaterne i EU skal redegøre for hvordan en lignende udvikling også kan sikres for eksisterende bygninger. Active House Specifikationer giver et bud på hvordan dette kan gøres ( www.activehouse.info )

  17. Forslag til tagrenovering med solceller for bevaringsværdigt byggeri v. Hvidovrebo i Hvidovre er netop godkendt efter 1½ års sagsbehandling.

  18. På basis af Københavns Kommunes Klimaplan hvor man har som mål at være CO2 neutral i år 2025, har man nu besluttet sig for at være åbne over for solceller også når de kan ses samtidig med at man dog forbeholder sig nogle skrappe krav til den arkitektoniske løsning, noget som sker i dialog med Center for Bydesign og Stadsarkitekten i Københavns Kommune.

  19. På det flade tag er der indpasset lige så mange solceller, men her er det ikke muligt at se dem fra gadeplanet. Dette har haft en tydelig økonomisk effekt, idet solcellerne på det flade tag er udført for en pris på ca. 21.000 kr./kWp, mens de synlige flader har kostet 32.000 kr./kWp (ca. 50 % mere).
