CCG has launched the ‘CCG net zero home’, a new standard for housebuilding to respond to Scotland’s ambitious net zero targets

The Net Zero Home is created using a combination of CCG’s expertise in the offsite manufacture of timber systems and building services to deliver a standard of specification that reduces Greenhouse Gas Emissions to a rate less than or equal to 0kg.C02/M2/Year.

The outcomes of analysis have shown that when compared to the baseline Section 6 standard for housebuilding in Scotland, the Net Zero Home standard can reduce dwelling emissions by up to 98% whilst energy costs to the end-user can be reduced by as much as 394% (average costs from £117 per year) in houses and 167% (average costs from £334 per year) in flats.

Based on a gas-free solution, compliance has been demonstrated across a wide range of house and flat types as a result of using Dynamic Simulation Modelling with Standard Assessment Procedure (SAP), a methodology for calculating the energy performance of dwellings, enabling the standard to be applied to developments of varying forms and size.

Combining expertise to deliver reductions in carbon emissions

Managing director of CCG, David Wylie, said: “For CCG, it was crucial for us to understand the environmental benefits that could be achieved through the use of our existing construction methods and technologies.

“Our capabilities in offsite manufacturing are some of the most advanced in the UK and we wanted to build upon this position to ensure that the Net Zero Home standard could be delivered to a mass market as efficiently and cost-effectively as possible.

“To do this, we partnered with Carbon Futures to undertake detailed analysis of energy performance and MAST Architects to design a suite of fully optimised house types.

“The results prove that if we combine our in-house expertise in construction, manufacturing and building services, regulated operational net zero is achievable today and is capable of delivering a significant reduction in carbon emissions and energy costs for tenants and homeowners alike.

“The Net Zero Home standard will ensure that CCG plays its part in meeting the Scottish Government’s climate targets and will remain at the forefront of housebuilding in Scotland for many years to come.”

Director of MAST Architects, Mark Johnstone, added: “MAST are delighted to support CCG in the launch of their Net Zero Home delivering mixed-tenure energy-efficient warm and healthy homes in safe and well-connected communities.

“Our work with CCG is supported by a suite of preferred construction details, prepared by MAST, that have been optimised to facilitate the delivery of an innovative product which focuses on a thermally modelled fabric first approach, balancing issues of energy-efficient renewable technologies, buildability, capital and costs in use.

“Like CCG, we work to exceed the minimum standards, promoting innovation and change in the housebuilding sector.”

CCG’s first confirmed net zero project will commence in 2021 with North Lanarkshire Council where a total of 19 ‘pilot’ homes will be constructed as part of a wider 150-unit regeneration in Airdrie.
