Zero energy retrofit in the Netherlands

Back to News

In the latest Beacon Blog, Nick Collins reports on his visit to a large scale retrofit pilot in the Netherlands.

Most states and cities in Europe have a significant proportion of their housing stock, built in the post war period from 1950 to 1980, which is uninsulated, requires large amounts of energy to heat, and has a significant amount of deferred maintenance. The Netherlands is no exception.

A large proportion of these houses are owned by Housing Associations , and it is through these associations that the Energiesprong (literally Energy Jump) initiative works.

Energiesprong turns the building market on its head to deliver social housing with zero net energy consumption, i.e. no energy bill, at zero cost to the tenant and with no subsidies to the builder.
