Vision and objectives
Building integration of photovoltaics replaces traditional elements (windows, cladding, roofs or accessories) with a functional component able to generate energy. The main goals of PVadapt project is to provide a cost-effective, smart, sustainable BIPV
Key aspects (drivers that can lead to price reduction):
Prefabrication of BIPV components can reduce not only on-site work and waste, but also the costs of the components, in conjunction with the selection of appropriate materials. Prefabrication will also lead to substantially faster installation times for refurbishment, and even more so for new construction.
Modularity as a design philosophy rather than a function. Modularity in BIPV product architectures can facilitate the work of architects and engineers and enable them to meet and exceed the expectations of the end-user. A modular BIPV component is designed to be customizable by design, to fit specific requirements without increasing costs. Likewise, a PV module can be similarly adapted to specific applications, often at lower costs through the replacement of components such as glass with metal foils.
Smartness: Apart from improving energy efficiency and reducing energy costs, through smart-house systems the consumer has a clear picture of the energy profile of his building and can adjust his behaviour accordingly. It makes sense, that any innovation in BIPVs is coupled with smartness, benefiting the consumer on a micro scale and society on a macro scale.
Studies predict cities will house over 80% of population by 2050, with global energy use in building doubling or even tripling by then. Currently, cities account for over 70% of global energy used and 40-50% of worldwide GHG emissions. It is thus difficult to envision a sustainable future without transforming the urban environment using powerful renewable energy technologies.
To that end, the utilization of BIPVs makes perfect sense in the urban environment. Building integration of photovoltaics replaces traditional elements (windows, cladding, roofs or accessories) with a functional component able to generate energy. As a market, the BIPV sector is expected to keep growing from a € 3 billion market in 2015 to € 26 billion by 2022, bringing 20 years of R&D into fruition.
While market growth of BIPVs might inspire confidence in the future, their market share will only be 7% of the total PV market by 2020, as opposed to the current share of 3%. The BIPV sector connects the Building and Construction industry (B&C) with the renewable energy industry and as such, is influenced by both.
The dynamic comeback of the European solar PV industry will create 94,000 new jobs between 2016 and 2021 and increase cumulative installations to beyond 140GW, positively affected by EU policies and the goals for 2020, 2030 and 2050.
These conditions present an excellent opportunity for collaboration between the B&C and solar energy sectors, as the reduction of BIPV system costs will increase their market penetration, in turn creating even more jobs, boosting the sector‘s economy and empowering member states to reach and/or exceed RES targets.
In comparison to Europe, PV installations in China are expected to exceed 250GW by 2020, readjusting policy orientation to favor decentralized generation instead of utility installations.
Let’s face it: it’s the economy!
This shift represents an additional opportunity for increasing the global presence of the European BIPV industry, on the condition that BIPV costs are significantly reduced, providing high performance and reliability systems at prices below € 200/m in terms of building components, or below € 2/W in the language of the energy industry.
Combining functional building elements with solar energy technologies leads to the BIPV market comprising a wide array of products with corresponding variations in price range: integrated roof systems are priced between € 200m2 and € 600m2, while tiles cost between 350 and 500€/m2.
A baseline assumption shows that the consumer will invest between € 5.02/W to € 5.72/W for roof-based systems.
For façade systems, the situation is similar with options available from 100 150€/m2 but featuring low efficiency thin film PV technology to high end sophisticated BIPV systems at € 750/m2.
Finally, smartness, as in Smart Homes might currently be the exception (8.5 million homes in Europe), but the outlook shows that by 2030 the vast majority of European homes will be using smart technologies.
Therefore, apart from improving energy efficiency and reducing energy costs, the consumer has a clear picture of the energy profile of his building and can adjust his behavior accordingly.
It makes perfectly sense that any innovation in BIPVs is coupled with smartness, benefiting the consumer on a micro scale and society on a macro scale.
There are four main pillars comprising the activities of the project.
The first pillar is the delivery of a PV/T component active energy component comprised of a sheet of flat heat pipes (Heat Mat-HM) in a PV module.
The second is the delivery of a prefabricated structural panel with multiple passive functions (thermal, resilience, stability, waterproofing among others).
The third is the delivery of a Smart Envelope System, achieving critical functions such as load prediction and shifting and predictive maintenance.
The fourth is producing an environmentally and financially viable result.
