Financial services firm Standard Bank is investigating the use of edge certification frameworks for renewable energy systems in households to enable it to access international green funding that it can then lend on to households to accelerate the rate of installation of renewable energy systems. Accessing sustainability, or green, finances requires certification and there is low penetration of edge certifications in homes older than five years, which makes it difficult for the bank to provide the required assurances to access green finances for household projects, says Standard Bank homeowners’ advice and services platform LookSee executive head Marc du Plessis.
