An additional mandatory requirement which refers to ‘Designing for
local drainage system failure’.

An exemption has been provided to some of the criterion
where selected pathways are subject to a steeply sloping
plot gradient.

When looking to achieve 2 credits (‘significantly beyond best practice’)
a minimum score of 4 must be achieved in each section.
Key changes
ENE 1: Dwelling Emission Rate
• Simply achieving a compliant DER/TER will mean that zero credits
are achieved.
• You will be 5 credits fewer than you would have had previously.
• Level 4 is achieved by gaining at least 25% improvement on
DER/TER (SAP 2009)
ENE 2: Fabric Energy Efficiency
• It replaces the Heat Loss Parameter.
• Energy demand for heating and cooling, it is measured in kWh/m2/year.
• Like the Heat Loss Parameter SAP calculates the figure.
• STROMA FSAP software will produce the figure (SAP Box 109).
• Block of apartments can be assessed as area weighted averages.
• Maximum of 9 Credits available where previously only 2 were available.
• Minimum of 3 credit available.
• Mandatory where Level 5 or 6 are sought.
ENE 3 – Energy Display Devices
• It replaces Internal Lighting, which was previously required.
• The purpose is to measure and transmit the energy consumption to a
visual display unit.
• Raise awareness of energy consumption in dwelling
• Primary Heating Fuel - The fuel used to provide the majority of the heat to the dwelling under assessment
• Correctly Specified Energy Display Device - self-charging sensor fixed to the incoming main supply. As a minimum, it must display:
– Local Time
– Current Mains energy consumption
– Current Emissions
– Current Tariff
– Current Cost
– Display Accurate Account Balance Information
– Visual Presentation of data
– Historical Consumption
SUR1 - Surface Water Run-Off
• Clearer guidance in the Assessment Criteria
• Clearer definition of ‘Appropriately Qualified Professional’
• Clearer guidance in the Assessment Methodology
• Third mandatory requirement
• The allocation of credits has been split
SUR1 - Surface Water Run-Off
• Written into the Assessment Criteria is:
– If there is no increase in the impermeable area as a result of the new
development, then the peak rate and volume of run-off criterion does
not apply (Mandatory met).
– The additional predicted volume of rainwater discharge for the 100 year
6 hour event must be prevented from leaving the site by using infiltration
or other SUDS techniques e.g.
• Wet ponds
• Rainwater harvesting
• Soakaways
SUR1 - Surface Water Run-Off
• Appropriately Qualified Professional
A professional or team of professionals with the skills and experience to
champion the use of SUDS within the overall design of the development
at an early stage.
The professional or team of professionals must be capable of
understanding the site’s particular surface water management needs
and opportunities. In addition, they must have knowledge and
experience in using SUDS-based solutions to influence the holistic
design of a development’s drainage system and provide the robust
hydraulic design calculations referred to in key guidance documents
such as The SUDS manual (CIRIA C697, 2007) and Preliminary rainfall
runoff management for developments (EA/DEFRA, 2007).
Suitable professionals may be found in a variety of disciplines, such as
engineering, hydrology or a combination.
Geotechnical advisers or specialists may be required for SUDS
techniques that allow infiltration.
SUR1 - Surface Water Run-Off
3rd Mandatory Requirement
• Designing for Local Drainage System Failure –
Demonstrate that the flooding of property would not occur in the event
of local drainage system failure (caused either by extreme rainfall or a
lack of maintenance).
• Further guidance - CIRIA publication C635 (2006) Designing for exceedence
in urban drainage – good practice should be referred to for guidance.
• Evidence Requirements –
Drawings showing the proposed drainage solution, system failure flood
flow routes, potential flood ponding levels and ground floor levels.
Confirmation from the appropriately qualified professional that local
drainage system failure would not cause an increase in the risk of
flooding within dwellings either on or off site.
One credit can be awarded by ensuring there is no discharge 1
from the developed site for rainfall depths up to 5 mm
One credit can be awarded if the run-off from all hard surfaces shall receive an
appropriate level of treatment in accordance with The SUDS
Manual to minimise the risk of pollution.
WAS 2 – Construction Site Waste Management (3 Credits available)
• A additional credit available
• It is no longer a mandatory requirement under Code
• Encourages more non-hazardous waste to be diverted from landfill
• Third credit means that the weighting factor is lower
Minimising Construction Waste
1 Credit:
Where there is a compliant SWMP that contains:
a. Target benchmarks for resource efficiency, i.e. m3 of waste per 100 m2
or tonnes of waste per 100 m2 set in accordance with best practice
b. Procedures and commitments to minimize non-hazardous construction
waste at design stage. Specify waste minimization actions relating to at
least 3 waste groups and support them by appropriate monitoring of
waste.
c. Procedures for minimising hazardous waste
d. Monitoring, measuring and reporting of hazardous and non-hazardous
site waste production according to the defined waste groups (according
to the waste streams generated by the scope of the works)
1 Credit:
Diverting Waste from Landfill
Where there is a compliant SWMP including procedures and commitments to
sort and divert waste from landfill, through either;
a) Re-use on site (in situ or for new applications)
b) Re-use on other sites
c) Salvage/reclaim for re-use
d) Return to the supplier via a ‘take-back’ scheme
e) Recovery and recycling using an approved waste management contractor
f) Compost
AND
One of the following has been achieved:
Where at least 50% by weight or by volume of non-hazardous construction
waste generated by the project has been diverted from landfill.
2 Credits:
OR
Where at least 85% by weight or by volume of non-hazardous construction
waste generated by the project has been diverted from landfill.
HEA 4 – Lifetime Homes
• Still mandatory for Level 6
• An exemption has been provided to some of the criterion where selected
pathways are subject to a steeply sloping plot gradients.
MAN 2 – Considerate Constructors Scheme
• Achieving a score of at least 3 in every section for best practice.
• Achieving a score of at least 4 in every section for significantly beyond
best practice.
