The new Part L2 Conservation of Fuel and Power in new buildings other
than dwellings Building Regulations came into force April 2006. To
fall in line with the EU Energy Performance in Buildings Directive the
new L2, Part F (Northern Ireland) and Section 6 (Scotland) documents requires
a major change in the way buildings are to be assessed for compliance with
energy efficiency and carbon emission standards.
Part L2 divides into five separate criteria to be met, noting that some
of the criteria are interdependent with each other:
Criterion 1 – Achieving an Acceptable Building CO2 Emission
Rate
Criterion 2 – Limits on Design Flexibility
Criterion 3 – Limiting the Effects of Solar Gains in summer
Criterion 4 – Quality of Construction and Commissioning
Criterion 5 – Providing Information (for the building operator)
Criterion one requires the proposed building to be modelled and simulated
using an accredited software tool to evaluate the carbon emission from a “notional
building”, of the same geometry and function as the actual building
(using the National Calculation Method Database). An improvement factor
is then applied to establish a target emission rate (TER) against which the
actual design Building Emission Rate (BER) must equal or better. This
requirement may be fulfilled utilising the iSBEM tool from the BRE. Assessments
are carried out by consultants who are registered as “competent persons” under
BRE Certification Limited.
