Three demonstration buildings will be available for the project

  • Large experimental facility for smart-grids electrical testing: INGRID. (Bilbao, Spain). New building.
  • Uni-familiar residential house (Pikermi, Greece). Retrofitting.
  • Residential complex, several uses (Mons, Belgium). New building.

The three buildings have been designed according to bioclimatic and energy efficiency concepts, as will be detailed below. Building typologies and locations have been selected attending to the following purposes:

  • Different types of buildings, in order to consider several designs and buildings uses, favouring the future market expansion in different building environments.
  • Different markets: new building and retrofitting are addressed in the demonstrations.
  • Different countries to analyse how different climatic conditions and general PV environment (drivers and barriers, different legal and regulatory framework, technology development, social awareness, market deployment, possible business and services models, etc.) affecting the technical and economic feasibility of the developed PV components.

The feedback provided from these three demonstration sites will allow for useful technical, policy and marketing solutions to encourage increased deployment of BIPV.

DEMO BUILDING 1: INGRID – New building – Zamudio, Spain

INGRID is the name of TECNALIA’s recently inaugurated experimental infrastructure for smart grids. It is located in Zamudio (near Bilbao, Spain). It is composed of two buildings, one for testing laboratories and another one for offices. This last building has been chosen as demonstration site. The whole building has been projected following energy efficiency design guides.

The south-east façade will be covered with the photovoltaic triple glazing system curtain wall based on fibre reinforced composite materials developed within the project. A total area of 18 m2 will be covered with the BIPV curtain wall. 10 PV modules will be installed with a total power of 1.28 kWp. The total estimated yearly energy production is 1229 kWh/year.

The BIPV skylight will be also installed in this building. A full integration was not possible in this case, so the demonstration will be limited to assessing the PV performance of the composite, directly mounted over the actual roof. Eighteen semitransparent skylight modules will be installed, leading to an installed power of 1.60kWp. The expected annual energy production of this installation will be around 2238 kWh/year.

DEMO BUILDING 2: RESIDENTIAL BUILDING – Retrofitting – Pikermi, Greece

The demonstration site in Greece is an individual residential building owned by HERON. The building is a low energy residence, completely designed and built by HERON and equipped with a geothermal heat pump, which covers the heating/cooling/DHW needs 100%.

In this case, the ventilated façade PV module and the solar shading system will be the elements to demonstrate, as they are the most suitable elements for the Greek climate, with high levels of solar radiation and cooling needs.

Nine BIPV ventilated façade modules (2.43 kW) and five shading systems (0.5 kW) will be installed over the south-west façade of the household. Additionally, the two balconieswill be covered with the assembly of 17 basic PV units (1.1 kW).

DEMO BUILDING 3: RESIDENTIAL BUILDING – New building – Mons, Belgium

The roof of a new residential household will allow the demonstration of the composite BIPV roofing shingle. The total installed power will be 8.2 kW through the integration of 57 roofing shingles (40º tilt), leading to 6,934 kWh/year of generated electricity.

In terms of manufacturing this is the most challenging product, demanding a high replicability and fabrication rate. The building is currently under construction, and is expected to be finished by August 2015.
