This energy is used to control room ventilation, a requirement of the passive house standard.

NO LIMITS — 26 NO LIMITS — 27 VSG Laminated safety glass modules in special designs Very little is impossible!
ertex-solar have an excellent international reputation for their production of photovoltaic modules. Naturally, more and larger competing photovoltaic businesses are created each year. In the field of special module construction, an area where ertex-solar excel, using laminated safety (insulating) glass in all conceivable shapes and solar cell combinations – there are truly few competitors worldwide. The success in this area is no coincidence and is due to consistent achievements and a year-long concentration on this 1. 2. niche market. Contributing to this success is also the specialist knowledge and prototype developments - so special orders are highly welcome!

NO LIMITS — 30 NO LIMITS — 31 PLANNING The impact of shadows Playing with shade
“Where there's light there's shade” is a common expression. This logic also holds true when planning photovoltaic installations within building constructions. The contrast between the direct sunlight and the dark areas created by the PV-cells, in the main, casts airy dramatic shadows.
As a rule, photovoltaic modules inevitably produce shadows but these can be deliberately used as an essential design element. Every cell type, cell gap and application area (overhead, warm façade, etc) affect sun light and as a result, the control of warmth and room climates.
Simulating unwanted side effects
But for all that, it is necessary to consider possible shading issues before installation. Not only do the canopy of the Community Centre of Ludesch (right), or the outside section of the Chamber of Commerce Hall in Schwechat (left), have an extremely attractive look, but in contrast to usual offices or work places, they do not suffer from the usual side effects associated with shade. It is, therefore, advisable to consider a large-scale simulation, even if only an outline of what is planned.
