The overall onsite contribution to zero carbon (including energy efficiency above) is called Carbon Compliance. This includes on-site low and zero carbon energy such as PV and connected heat such as a community heating network.

Carbon Compliance: Setting an appropriate limit for zero carbon new homes - Findings and Recommendations

A Task Group convened by the Zero Carbon Hub has delivered this report to the Minister for Housing and Local Government (February 2011) setting out its recommendations for carbon compliance levels for new homes from 2016.

Carbon Compliance: What is the appropriate level for 2016? - Interim Report

A Task Group convened by the Zero Carbon Hub has delivered a report to the Minister for Housing and Local Government (December 2010) setting out its recommendations for carbon compliance levels for new homes from 2016.

The Task Group has submitted recommendations to Government about how to make the next steps in achieving zero carbon as effective as possible whilst being compatible with delivery of the full range of housing required.

Overview Report - Carbon Compliance for Tomorrow’s New Homes -A REVIEW OF THE MODELLING TOOL AND ASSUMPTIONS - This forward-looking review launched by the Zero Carbon Hub and sponsored by the NHBC Foundation, details the findings of an expert Task Group which considered whether the existing carbon compliance tool is appropriate for low energy/zero carbon homes (7.9 mb).

	Supporting topic and modelling reports	Size	Date
	Topic 1 – Carbon Compliance tools consideration (currently unavailable) Looking at modelling tools currently available both here and abroad and considering key characteristics, what they assess and the trade off between accuracy and ease of use.	tbc	tbc
	Topic 2 – Carbon intensity of fuels Considering the implications of, and an appropriate response to, the changing carbon intensity of electricity and other fuels.	15.3 mb	October 2010
	Topic 3 – Future climate change Setting out how projected national and local climate changes could affect energy demand. Exploring for example how the compliance tool should embrace overheating risk.	3.9 mb	August 2010
	Topic 4 – Closing the gap between designed and built performance How the compliance tool should accommodate (and help reduce) any performance gap between design performance and what is achieved on site.	1.8 mb	August 2010
	Topic 5 – How the performance standard should be expressed This looks at whether carbon compliance should be expressed as an improvement versus a notional building (as now) or in absolute terms (kgCO­2 emissions per unit area).	1.5 mb	August 2010
	The modelling supporting this review (currently unavailable) Sets out the modelling undertaken to support this programme of work.	tbc	tbc
