Type of building Advantages (along with the

integration Description of the system Requirements production of electricity)

Into the roof the system is part the system should be part of an impermeable

of the external skin layer in the construction

the system is above the the impermeable layer has to be pierced in

impermeable layer order to mount the system on the roof

if the PVs are transparent → sun protection (avoid overheating in

serve as water and sun summer) in glass-covered areas, such as

barriers and also transmit sunrooms and atriums

daylight

Into the façade glass or frameless orientation is important: facade systems might be shade, protection from rain

PVs for sunshades, suitable in certain countries, especially at a northern

louvers and canopies (above 50 ◦ N) or a southern (below 50 ◦ S) latitude

PV systems as part of PVs replace building elements; PVs are

a passive cooling very well ventilated at the back; a separate

strategy (specific case) mounting construction is not necessary;

the air-conditioning system is eliminated

All the types of technical aspects of PV, cables and inverters

building integration a structure strong enough to withstand

wind or snow loads
aesthetic quality → criteria formulated
by the IEA PVPS Task 7 workgroup for the evaluation
of the aesthetic quality: natural integration,
architecturally pleasing designs, good composition
of colours and materials, dimensions that fit the
gridula, harmony, composition, PV systems that
match the context of the building, well-engineered
design, use of innovative design
ventilation at the back of the modules (not
important for thin film a-Si)
shadow is not allowed on the modules; the mounting
and removing of the modules should be easy; the
modules should stay clean (or can be cleaned);
the electrical connections should be easy; the
wiring should be sun-proof and weather-proof
