SCOTLAND TO BE

NET ZERO BY 2045

NO GAS IN NEW

BUILD HOMES FROM 2024

REDUCING EMISSIONS

AND CREATING SAVINGS

THE CCG NET ZERO HOMEThe Scottish Government has set an ambitious target to become a net zero economy by 2045 with a phased

introduction of a more environmentally-focused standard of living in response to the emerging climate crisis.

For housebuilding, de-carbonisation is set to commence as early as 2024 with the

removal of gas from all new build homes whilst the affordable housing sector, namely

Local Authorities and Registered Social Landlords, will be required to achieve net zero

in all new build homes from 2026.

CCG has pioneered the manufacture and use of offsite-manufactured timber systems

for over a decade with the creation of over 10,000 homes using a ‘Fabric First’

approach to design and construction. We value innovative thinking as part of our

vision for housebuilding in Scotland and in doing so, we recognise that if we are to

sustain housing supply whilst achieving our essential targets, there requires to be the

rapid alignment of policy with construction methods and resources.

The time to move toward net zero is now. It is time for the CCG Net Zero Home.

THE NET ZEROJOURNEY

The CCG Net Zero Home is a new building standard that reduces Greenhouse Gas Emissions (GHG) associated with regulated operational

energy arising from heating, cooling, lighting, pumps and fans.*

Calculations are based upon achieving a Dwelling Emissions Rate (DER) less than or equal to

0 kg.CO2/M2/Year and CCG has demonstrated compliance across a wide range of house and flat types

using the Standard Assessment Procedure (SAP) against Section 6, Section 7, Platinum Level 1 and Gold

Hybrid of the current Scottish Government Building Regulations using an entirely gas-free solution.

Dynamic simulation modelling, which includes analysing weather data, occupier use and solar gain, has

also been carried out to establish accurate running costs which offer a real comparison against the

alternative industry standards.

For CCG, our objective has been to ensure that the Net Zero Home standard is accessible to all within the

Scottish housebuilding sector. To do this, we have sought to use the existing construction methods and

technologies from within the CCG's existing group structure. In doing so, we are able to ensure that the

Net Zero Home standard can be produced en mass as efficiently and cost-effectively as possible.

By working with industry partners MAST Architects and Carbon Futures, CCG has created a range of

homes that are fully optimised in their design and future-proof to the forthcoming changes in building

regulations. This will enable our clients to plan ahead with more certainty whilst tenants and

homeowners alike will benefit from the long-term advantages generated from reduced energy costs.

**Net Zero currently is without formal definition and universally accepted methodology. Our figures do not

consider in-use performance (unregulated energy - media equipment, appliances) nor does it consider

embodied carbon where an accurate Life Cycle Assessment is required. It should be stated for

completeness that if these are to be accounted for in calculations then more energy efficiency,

sustainability, and carbon offsetting practices may need to be implemented to achieve net zero.

Page 4: THE CCG NET ZERO HOME

RENEWABLE TECHNOLOGYSolar photovoltaic (PV) panels are installed to the roof in order to convert sunlight into electricity

with the number of modules applied to each dwelling based upon the maximisation of solar gain.

Clients have the choice of introducing battery storage which takes the energy captured from the

panels and stores it for later use, thus, allowing the end-user to benefit from energy that may

have otherwise been wasted. Whilst the addition of battery storage is not needed to achieve

operational net zero, we believe the long-term benefits are highly significant when considering the

£460 average annual energy cost saving across our range of house types compared to the Section

6 baseline as well as the vast reduction in carbon emissions as a result of lower demand.

VENTILATIONCCG recommend the use of a Decentralised Mechanical Extract Ventilation (dMEV) system

rather than a Mechanical Ventilation and Heat Recovery (MVHR) as part of the Net Zero Home

specification. MVHR is a component that is proven to be expensive for clients and end users

alike thanks to its high capital cost, operational difficulties and long-term maintenance

requirements. The dMEV offers a more simplified, cost-effective approach by generating

added value through its ease of operation and reduced reliance on long-term maintenance

whilst ensuring comfortable levels of air-flow.

BUILDING FABRICCCG place emphasis on a Fabric First Approach to construction through the use of the ‘iQ’ Timber

System, an enhanced, closed panel timber frame wall solution that combines with floor or roof

cassettes to create a vastly-improved building fabric. The System is inherently efficient with

enhanced U-Values achieved in the ground floors, external walls and roofs delivering vastly-

improved levels of airtightness. Complemented by low U-Value components such as the CCG-

manufactured PVCu, triple-glazed windows and enhanced external door sets, heat transfer and

loss is significantly reduced throughout each dwelling.

LOW CARBON HEATINGAs an alternative to a conventional gas-combi boiler system, CCG propose the use of a fully-

electric system for our house types with Air Source Heat Pumps (ASHPs) providing a solution to

space and hot water heating. Located externally, the ASHP extracts ambient air to heat a

liquid refrigerant that is then compressed to steam before returning to a liquid solution to

release heat to radiators or under-floor heating. Clients have the flexibility to choose

specification based upon individual requirements.

RENEWABLE TECHNOLOGYConventionally, solar PV is installed to the roof of a flatted building either as part of a

mounting system or with modules that are integrated into the fabric (in-roof) and are

connected to a landlord supply (communal). In the case of achieving operational net zero,

energy generation is maximised by a combination of the number of panels (restricted by roof

space), building orientation and connecting the system directly to each dwelling (as opposed

to the landlord supply )with the introduction of battery storage in this instance also delivering

a significant reduction on energy costs. Turnkey solutions are available as a result of CCG's

in-house expertise in order avoid over-specification and maximise efficiencies.

VENTILATIONFor flatted developments, CCG would continue to propose the use of a Mechanical

Extract Ventilation (MEV) system in order to support net zero compliance. Designed to

draw moisture laden air out of wet rooms (bathrooms and kitchens), the low-energy,

continuous extract capability of MEV provides our clients with a cost-effective, easy-

to-use system that will generate long-term added value for clients, tenants and

homeowners alike.

BUILDING FABRICCCG would continue to utilise the ‘iQ’ Timber System for net zero flatted developments.

Capable of being used entirely for a build (with the exception of communal areas)

reaching up to six storeys, the System offers significant advantages in improving density

by the most sustainable means. Low U-Value components (CCG-manufactured PVCu,

triple-glazed windows and enhanced external door sets) are again utilised in order to

promote a reduction in heat loss and energy demand, helping contribute to an average

annual reduction in emissions of up to 96% when compared to the Section 6 baseline.

LOW CARBON HEATINGVarious forms of heating systems can be used to reach operational net zero compliance. A gas-

free, communal Air Source Heat Pump (cASHP) system operates similar to that of a conventional

district heating network where a number of ASHP units are housed within an externally-located

energy centre connected to an underground pipe network which rises up through the communal

cores of each flatted block and delivers space and water heating to individual dwellings. An

alternative is a ground source solution (shared Group Array) where heat in this instance is

collected from the ground via boreholes and distributed by heat pump-based district heating

network. Increased capital costs are resultant from the Shared Group Array but the system is

advantaged by a reduction in seasonal temperature variation throughout the year.
