Jersey: Jersey Energy Efficiency Requirements Discussed At Ogier Seminar
Last Updated: 22 July 2016

New requirements for insulation and energy efficiency upgrades where major renovation work is being carried out have come into force today.

A seminar last week – which was sponsored by Ogier and which took place in the firm's Esplanade offices – saw Planning's Director of Building Control Mo Roscouet discuss the coming changes to energy efficiency requirements under Planning bye-laws.

For applications submitted from today, any major renovation work involving more than 25% of the surface area of the building envelope, or more than 50% of the thermal elements surface area will require "thermal upgrades" to improve the energy performance of the building.

If a domestic building is being extended then 5% of the value of the extension works must be spent on thermal improvements in the rest of the house, but for a non-domestic building of 1,000 square metres or more where an extension is proposed that figure increases to 10% of the value of the principal works.

Speaking after Thursday's Jersey Construction Council (JeCC) seminar, which was attended by around 50 professionals, Claire Smith, Planning & Construction Lawyer at Ogier, said "These bye-law amendments raise issues for anyone considering work on protected and older properties in particular.

"It was reassuring to hear at the seminar that the Planning and Buildings applications teams at the department will be liaising closely on this subject.

"We can all see the value in improving energy efficiency, especially with figures showing that 30% of Jersey's emissions come from domestic buildings, but the concern from the industry's point of view is that these well-intentioned rules could actually stop some work going ahead."

All the changes are set out in Technical Guidance Documents 11.1A (new dwellings), 11.2A (new buildings other than dwellings), 11.1B (existing dwellings) and 11.2B (existing buildings other than dwellings) which can be found on the States website.

JeCC members expressed some concern that there was no incentive on members of the public to replace old non-condensing boilers for new models now that grants to do so were no longer available from the States. Mr Roscouet pointed out that increasing the energy efficiency in existing buildings would result in cheaper energy bills in the long run so improvements in thermal efficiency paid for themselves over time.
