Researchers demonstrate technical feasibility of retrofitting PV-driven heat pumps in multi-family buildings A research group led by Germany’s Fraunhofer ISE has conducted what it describes as the first empirical study on PV-assisted two-stage HP systems in existing multi-family buildings. Its findings show that substantial PV electricity exports result in greater avoided non-renewable primary energy use.

Custom standardization: unlocking BIPV The creativity of architects and the need to standardize BIPV products to bring costs down may appear mutually exclusive. In reality, they are the concurrent needs of both the construction and solar sectors and must be considered for the promise of “PV everywhere” to become a reality in our built environment. Work is underway to bridge this gap and the initial results are building in innovation.
