DUOWEIMetal Building Envelope Systems

New Energy and Environmental Power Buildings

New energy and environmental power buildings combine industrial envelope needs with energy equipment: roofs and walls that may also carry photovoltaic equipment, planned as one system with the building surface.

What building-integrated photovoltaics means

Building-integrated photovoltaics means photovoltaic equipment that forms part of the building itself, rather than equipment added on top of a finished roof or wall. The photovoltaic surface and the building surface are planned as one system, so the roof or wall design and the energy equipment design move together.

This site describes building-integrated photovoltaics at system level only. Power ratings and energy output figures are not published here; please confirm any energy requirement in your inquiry, and treat it as a point to be confirmed rather than a published claim.

What the metal envelope system covers

The metal building envelope is the outer system of an industrial building: the wall and roof surfaces that close the structure, together with the supporting steel structure that carries them. On this site the envelope is presented as a system, not as a single panel product, because the wall, the roof and their junctions have to be planned together before any panel is ordered.

A buyer who approaches the envelope as a system will usually start from the building itself: what the building is used for, how its interior is organised, and which wall and roof areas need to be closed. Those answers shape the inquiry, and the inquiry shapes what can be supplied. This site therefore describes systems and inquiry steps, and it does not publish a specification table.
