L’esigenza di incrementare la produzione di energia rinnovabile, per il soddisfacimento di bisogni energetici, sta diffondendo nuove tipologie di sistemi fotovoltaici, i “Building Integrated Photovoltaics”.
I BIPV non sono altro che impianti fotovoltaici integrati negli edifici come elementi architettonici, costruttivi e funzionali dello stesso.
A partire dal 2020, come previsto dalla direttiva europea 2010/31/EU, tutti gli edifici di nuova costruzione dovranno essere NZEBs (Nearly-Zero Energy Buildings), ovvero a bilancio energetico (quasi) nullo.
I componenti edilizi che possono costituire BIPV sono:
- parti dell’involucro dell’edificio (copertura, rivestimento facciate/vetrate);
- dispositivi di schermatura solare, visiva e auditiva;
- elementi architettonici accessori (parapetti, pensiline..).
Ai sistemi fotovoltaici BIPV è dunque demandata multifunzionalità ed esteticità, sempre nel rispetto dei criteri di efficienza energetica, tipici anche degli impianti fotovoltaici tradizionali.
Le funzioni edilizie richieste sono:
- protezione dagli agenti atmosferici;
- resistenza meccanica ed integrità strutturale;
- ombreggiamento;
mentre a livello estetico:
- posizionamento e dimensioni dei moduli, che devono essere coerenti con quelle dell’edificio;
- materiale, colori e texture dei moduli devono essere in armonia con il resto della struttura;
Esclusi da tale definizione sono gli impianti “fissati” o “appoggiati” su coperture o altre parti dell’edificio, che non hanno altre funzioni oltre alla mera produzione di energia elettrica.
Si tratta di un sistema modulare, molto semplice da montare. Attualmente il mercato dei BIPV offre diverse soluzioni, anche esteticamente molto gradevoli.
Essendo parte del sistema architettonico e del generatore di energia, gli elementi fotovoltaici dei BIPV permettono di ridurre i costi di investimento iniziali, in quanto materiali e manodopera impiegati sono minori rispetto alla tradizionale installazione di un impianto fotovoltaico.
“You get some of me but not tomorrow as they want me in as soon as I can make it happen. This is the one time when they say jump and I ask how high due the financial gains the company could benefit from and it being important enough for the client to appear in person.”
“Well I get an extra night of you at least! I wonder what we could do with that? Meantime, what about food? I am starving and delicious as it was a second breakfast is not quite enough to replenish me!”
“Well get something on and we’ll sort that out first.”
We drove into town and decided that a daytime visit to Charlie’s was going to be the answer. I parked in the bar lot and Elise dashed in to change into something more appropriate, jeans and a t-shirt along with her biker jacket but keeping her Converses on.
Walking down to the restaurant was different from the middle of the night visits as the streets were bustling and all of the shops and outlets were open.
Reaching Charlie’s we entered the front door and sat in a booth near the window. A beautiful young American Chinese girl came,smiled and said hello to Elise and gave us menus and asked if we wanted drinks in the meantime.
“No thanks Lin just a pot of Jasmine tea for us please.” Lin went back to the kitchen area. “No booze for me today as I will have to work in the bar so it is just tea for me.”
Not in a drinking mood either, I agreed with her.”
