Cuba BIPV solar curtain wall design

How can a BIPV/T curtain wall improve thermal performance?

Rounis et al. designed and experimentally tested a BIPV/T curtain wall with thermal enhancement techniques like airflow deflectors, multiple inlets, and semi-transparent rather than opaque PV. The optimized design achieved a 3.5 °C reduction in peak PV temperature and 16% better thermal performance.

Why is PV curtain wall technology important?

As an effective means of energy conservation and emission reduction, PV curtain wall technology has been extensively promoted since it is not only significant from the perspective of electrical gain but also allows for the collection and reuse of the generated heat in conjunction with air-conditioning systems.

Can PV curtain wall systems reduce overheating and save energy?

To address overheating and save energy in air conditioning, this study proposed novel single- and dual-inlet ventilation PV curtain wall systems (SVPV and DVPV). In summer, the building exhaust is introduced into the channel to strengthen PV cooling, while incoming fresh air is used to preheat dew-point air.

How does a single-inlet ventilated PV curtain wall system work?

This section describes the operation of the single-inlet ventilated PV curtain wall system using a novel HR technique for fresh and supply air handling (SVPV), along with the dual-inlet one (DVPV), taking the conventional non-ventilated one without HR (NVPV) as a reference system.
