Evaluation of an energy and water efficiency retrofit project in social housing

Evaluation of an Energy and Water Efficiency Retrofit Project in Social Housing

This pilot project set out to assess the impact of retrofitting social housing.

The Greening of Social Housing project aimed to assess the impact of energy and water retrofits with the view to piloting an approach to making the business case for further projects. This report covers the quantitative aspects of the project.

Several key learnings emerged from the assessment:
  • On average, tenants are saving as a result of enhanced energy efficiency.
  • There is some tentative evidence of suppressed demand associated with extreme poverty.
  • Communicare - the landlord - also benefitted financially, realising a 95% saving on their December 2016 water bills.
  • The key short-term financial benefit to the City of Cape Town is a reduction in electricity subsidy in the high demand winter season.
  • To maximise the savings benefit to retrofits, it is critical for both landlord to take initial consumption patterns into account in the retrofit design, and for tenants to make effective use of the new technologies.
