Action needs to be taken on EU carbon emissions

/in ,

EU Building regulations state that all new buildings constructed within the EU must be zero–emission buildings by 2030 and new ‘public’ buildings must be zero–emission buildings by 2027.

WorldGBC has convened a coalition of 35 built environment stakeholder groups, representing over 5,000 organisations from across the building value chain, to call for high level ambition as Parliamentary negotiations on the Energy Performance of Building Directive (EPBD) enter their final stage.  With the vote approaching, the coalition is calling on politicians to seize a once-in-a-generation opportunity to eliminate carbon emissions from Europe’s building stock.

This past week WorldGBC has written an open letter to MEPs calling on them to:

  • Accelerate building renovation and address energy use and efficiency via the introduction of Minimum Energy Performance Standards and harmonisation of Energy Performance Certificates
  • Address total lifecycle emissions of buildings, including both operational and embodied emissions by supporting provisions regarding Whole Life Carbon reporting, targets, and thresholds

An ambitious EPBD revision will make EU building compatible with EU climate targets, take 35 million citizens out of energy poverty1 and unlock the economic benefits of creating up to 3.3 million green jobs in the EU every year2 while boosting local communities.

In Europe, buildings account for around 40% of energy consumption and 36% of CO2 emissions. Embodied carbon, which refers to emissions from the construction, renovation, deconstruction or demolition and the wider supply chain of a building, contributes typically between 10-20% of the EU building carbon footprint. This means that before a building is even in use, it has already contributed significant carbon emissions and depleted the EU’s ‘carbon budget’.

This letter comes amid growing political and industry support for policy that tackles the Whole Life Carbon impact of buildings.

Will England follow Scotlands lead in green building?

/in ,

All newly built homes in Scotland will need to conform to an innovative green building standard championed by a Labour MSP, under plans announced by the Scottish Government.

Labour’s Alex Rowley proposed the Domestic Building Environmental Standards (Scotland) Bill at the end of 2022 to introduce the Passivhaus standards for all newly built homes in Scotland.

The Passivhaus standards create ultra-low energy homes which aim to minimise the need to heat and cool buildings.

In a letter to Mr Rowley, Minister for Zero Carbon Buildings, Active Travel and Tenants’ Rights, Patrick Harvie confirmed that the Scottish Government would implement the standards within two years through secondary legislation – without the long process of a member’s Bill passed through Holyrood.

Homes built to Passivhaus level meet high standards of airtightness, insulation and energy efficiency, however the Scottish government has confirmed it is introducing its own ‘Passivhaus equivalent’ rather than using existing Passivhaus certification.

This Scottish equivalent will introduce minimum environmental design standards for new build homes to ensure they have high energy efficiency and thermal performance.

The Scottish government says it will implement the new standards within two years through secondary legislation. Development work will commence early in 2023 before the amendments are bought into regulations by December 2024.

A Passivhaus Trust spokesperson added: “It is fantastic to hear the Scottish government has committed to bringing forward a bill requiring higher energy-efficiency standards in domestic buildings, which also recognises the need to assure occupants that the design and construction of these buildings will deliver the actual performance sought in practice.

“Statements including ‘a Scottish equivalent to the Passivhaus standard’ and ‘explicit support for Passivhaus and equivalent standards’ fill us with hope. Now we must ensure that the bill is well developed and implemented to deliver the greatest impact on the actual performance of new homes in Scotland.”
