RIBA CALLS FOR GREATER FLEXLIBILITY ON ZERO CARBON DEFINITIONS


The Royal Institute of British Architects (RIBA) has called upon the Government to implement a more flexible definition of zero carbon to enable the construction industry to deliver low carbon buildings of the future.

Responding to the Definition of Zero Carbon Homes and Non-Domestic Buildings consultation (launched at the end of 2008), the Institute has called for a reclassification of district power and heating schemes, alongside a national energy trajectory to underpin future efforts to achieve 80% zero carbon by 2050. This would plot the UK’s route to decarbonising our energy supply, helping to address what constraints and opportunities exist in applying different clean energy technologies, and providing a roadmap and thereby increased certainty to local decision makers, the construction industry and its clients.

The RIBA has also proposed a reclassification of biomass and district heating systems through building regulations, in future to be considered measures of energy efficiency in buildings, rather than energy generation. The RIBA believes that reclassifying allowable renewables as only 'on site' would simplify the planning process. This could be easily overseen by the planning authority based on an objective assessment of available roof area, development density and orientation. The RIBA is proposing the planning process is simplified to ensure that all developments are future-proofed to accommodate renewables when they become viable.

Alan Shingler, Head of Sustainability at Sheppard Robson, who led the RIBA’s response said:

“The RIBA welcomes the proactive approach to legislate for energy efficiency and carbon reductions through the introduction of the Definition of Zero Carbon Homes and Non-Domestic Buildings consultation. We strongly support the 2050 target of reducing UK carbon emissions by 80% and, although new buildings will only represent a small proportion of these targeted carbon efficiencies, are encouraged that the Government has remained steadfast in its commitment to reduce carbon emissions from all new buildings.

“We encourage the more flexible approach to defining zero carbon, underpinned by a hierarchical approach to emissions reduction, which this consultation proposes. The RIBA also welcomes the ambition to define a similar framework for non-domestic buildings. Clarity of both targets and timescales will provide much needed certainty for the construction sector.

“Whilst we welcome the overall approach, we believe that the proposed legislative framework should not be allowed to confuse or dilute true zero carbon development which takes a holistic approach to sustainability including embodied energy, social and economic longevity, as well as environment and carbon reduction. It is imperative that the definition, and its implication become more transparent for both prospective purchasers and investors. The industry will always need a trailblazer and the ultimate aspiration to achieve true zero carbon should be encouraged.”
