<p data-pm-slice="1 1 []">The separate EPB Framework Consultation has suggested changes to the metrics used to produce an EPC. EPCs are often criticised for being an imperfect measure of the energy efficiency of a building. Proposals for new metrics suggest using standards set against either the 'fabric performance metric', 'heating system metric' or 'smart readiness metric'.</p>
Using new metrics in this way would require landlords to:
<ul class="custom-disc">
 	<li>improve the building’s heat retention,</li>
 	<li>reduce the energy required to operate the building’s heating, and</li>
 	<li>enable the occupier to optimise energy use and reduce running costs.</li>
</ul>
The government recognises that this is just one approach to utilising new metrics, and the EPC Framework Consultation seeks views on alternative approaches.
