	As the FHS is not fully defined and software to model it is not available, we developed an approach to modelling the FHS based on known information. This started with us establishing a baseline. To establish this baseline, we modelled the plots to meet the current Building Regulations, which gave us our ‘Maximum Kg CO2/yr’. We then re-modelled the units in SAP 10 and adopted two principles: a) we incorporated low carbon forms of heating and hot water generation; and b) we aimed for an 80% CO2 emissions reduction – this enabled us to determine the performance and design criteria for the particular plots.

New page

Climate change and what we can do to address it, both individually and collectively, has become the defining issue of our age. The expectation from Government, consumers and future generations alike will be for organisations to significantly reduce their impact on the environment, reducing their carbon footprint and creating less waste. This is an expectation enshrined in the UK’s legal requirement to bring all greenhouse gas emissions to net zero by 2050.

The Future Homes Standard

The UK’s housing stock accounts for about 15% of the UK’s annual greenhouse gas emissions. Because of this significant contribution the new-build housing sector is seeing a changing landscape in relation to the energy performance of the homes we produce in the future.<br />
The foremost challenge we face is The Future Homes Standard (FHS), which will become a Building Regulation requirement from 2025.

The FHS will see the introduction of tougher low- carbon regulation for new homes built from 2025. New homes will generally emit 75-80% less carbon than homes built under current regulations. This 75-80% reduction is to be achieved through a need to: meet more stringent building fabric requirements; utilise a low-carbon form of heating and hot water (including the probable introduction of a ban on gas boilers in new-build homes).
