Energiesprong
Energiesprong (English: Energy leap) is a program that originated in the Netherlands that introduced and retrofitted houses that satisfy energy efficient standards.[1] It has since been implemented in the United Kingdom, the United States, France, and Canada. The program typically consists of snapping a shell of panels to the outside of a building to increase its thermal efficiency.
Background
[edit]Energiesprong was created by the government of the Netherlands in 2010 to retrofit existing buildings for higher energy efficiency standards, becoming zero-energy buildings.[2] When the program was launched by the Dutch government, it initiated agreements with social housing companies and contractors to convert 111,000 houses in the Netherlands into near zero energy buildings.[3] Once a house is retrofitted, it would have net zero energy, which means it is capable of generating the total amount of its own energy requirements.[1]
Principles
[edit]The Energiesprong model increases the energy efficiency of new and existing buildings through the application of five criteria:[4]
- Performance guarantees for thirty years
- Implementation possible in less than one week
- Affordability created through energy savings and reduced maintenance costs
- Attractive design with upgraded features
- Procuring is based on purchasing housing concepts instead of detailed specifications and drawings
Energiesprong retrifitting typically involves snapping a pre-fabricated shell of panels to the exterior of a building to improve its thermal efficiency. The panels are created by taking a laser scan of the building's exterior to create a building information model, which can then be used for computer-aided manufacturing. The work can therefore be mostly completed at the factory, with installation taking less than one week.[5] In contrast to shallow retrofits such as the installation of heat pumps or basic insulation, energiesprong is considered a "deep" retrofit.[6] The renovations should pay for themselves in thirty years.[7]
Application
[edit]More than 5,000 homes in the Netherlands have been retrofitted with Energiesprong.[5] In 2018, the first ten homes were retrofitted in the UK as part of its Energiesprong pilot program.[7] Energiesprong has also been applied to buildings in France and Canada, as well as the US states of California and New York.[4]
In the United Kingdom, the home owner - after the refurbishment - pays a monthly fee, which is significantly less than the utility bills before the conversion - and a guaranteed free electricity and hot water.[8]
