Energy Performance Certificates (EPC’s)
•
Introduced as part of Energy Performance In Buildings Directive (EPBD) – Article 7
•
Inform potential building owners of energy performance of the building and to
make energy efficiency a factor in making a decision on properties
•
Phase in programme from 6th April 2008
6 April 2008
EPCs required for the construction, sale or rent of buildings, other than dwellings, with a
floor area over 10,000 m2.
1 July 2008
EPCs required for the construction, sale or rent of buildings, other than dwellings, with a
floor area over 2,500 m2.
1 October 2008
EPCs required on the construction, sale or rent of all remaining buildings, other than
dwellings.
Display certificates required for all public buildings >1,000 m2.
What are EPC’s and DEC’s?
•
Energy Performance Certificates and Display Energy Certificates
•
EPC’s have to be produced for buildings at construction, sale or let
•
Definition of a building – must have walls, roof and use energy to condition the
indoor climate (Heating, Mechanical ventilation and Air conditioning) HWS and
Lighting not included as they do not condition the indoor environment
•
A to G scale (A being most efficient and G is the least efficient)
•
Includes a Recommendations Report for Improvements
(based on a standard list but can be added to)
•
CO2 based Index
Energy Performance Certificates
•
Based upon Asset Rating of the Building and considers standardised uses,
building age, condition and the building services
•
Certificates held on a National Register for review. Data held for 20 years.
Lodgement Fee of £30
•
Calculated using Approved Software e.g. SBEM
•
EPC’s must be prepared by an Approved Assessor
•
Each Certificate will have a unique reference number
•
EPC’s to be prepared by the person selling or letting the
building
•
When new buildings being constructed the company
building the property must prepare the EPC
Energy Performance Certificates
•
EPC’s valid for 10 years but can be re-evaluated if improvements are made
to the building
•
Must be provided by the landlord to potential buyers or tenants.
•
Information required to produce an EPC
-
Scaled Floor Plans
Floor to ceiling heights
Window heights
Details of construction materials (U-values etc.)
Details of Heating, Ventilation and Air Conditioning
Details of Hot Water installation
Details of Lighting and lighting controls installation
Details of metering provision and any PFC
The more information and more detailed information
available the better the EPC is likely to be.
Do I need an EPC?
•
If you are selling or letting a commercial property
YES
•
If you are constructing a commercial property
YES
•
If you are modifying a commercial property so that
there are more or less parts of the property that can
now be sold or let separately and the modification
includes extension or provision of fixed building services
(heating, AC and ventilation) that condition the indoor climate
YES
•
Lease Renewal or Extension of a Lease
NO
•
Compulsory Purchase Order
NO
•
Lease Surrender
NO
•
Existing tenant with a current lease
NO
Do I need an EPC?
•
Place of Worship
NO
•
Temporary Building with Planned time of use of
less than 2 years
NO
Stand alone building with total useful floor area of less
than 50m2 that are not dwellings
NO
Industrial sites, workshops and non-residential
agricultural buildings with low energy demand
NO
•
Buildings that are due to be demolished
NO
•
Internal Refurbishment of Building, no change in parts
NO
but new building services
If new building services then likely to be more efficient and hence improved EPC –
so may be beneficial to have a new EPC.
•
•
Do I need an EPC?
•
It is the action of construction, selling or letting that triggers the need for an EPC
•
Transitional arrangements for buildings already on the market at 6th April.
Any building which is on the market before 6th April and remains on the market
afterwards will need an Energy Performance Certificate by 1 October at the latest.
•
Do companies want EPC’s even if they are not strictly required? – showing
commitment to sustainability and corporate responsibility.
Enforcement
•
By Trading Standards
•
Fine using a formula and can range from £500 to £5000.
•
Building Control will not issue Completion Certificates for new Buildings
WARNING!!!!!!
•
This is new and only now is it beginning to be used
•
There will be questions and answers are not always clear or known!
•
Particular care with shops in Malls and where buildings share common heating
systems
•
If unsure, get advice
EPC Guidance
• CLG Guide ‘ A Guide to Energy Performance Certificates for the Construction,
Sale and Let of Non-dwellings’
• CLG Guide ‘Energy Performance Certificates (EPC’s) and Non Dwellings: A
Guide for building owners, landlords and tenants’
• Downloadable in pdf from www.communities.gov.uk
• Ask an Accredited Energy Assessor.
DEC’s
•
Apply to Public Authority Buildings frequently visited by the public and over
1000m2.
•
Displayed in Reception of the Building
•
An Advisory Report is required with recommendations
•
To be based on actual metered fuel use (Operational rating)
•
Similar A to G scale to be used
•
CO2 Index
•
Must be prepared using approved software
•
Must be prepared by the building occupier
DEC’s
•
Must be prepared using accredited Energy Assessors
•
Must be carried out annually
•
Penalties for not carrying out the DEC or displaying the certificate
•
Important – Must have site floor areas/drawings and meter readings for all fuels
must be aligned along same/similar dates
Some EPC Examples
A Building with Common Heating System
A Building with Separate Heating System per floor
Some EPC Examples
Shopping Centres with Conditioned Central Space and Common Heating System
Shopping Centres with Un-Conditioned Central Space and Common Heating System
Some EPC Examples
Shopping Centres with Conditioned Central Space and Separate Heating Systems for
each Unit
Shopping Centres with Un-Conditioned Central Space and Separate Heating Systems for
each Unit
Some EPC Examples
Extension with extended capacity but no new parts added or removed
Extension with extended capacity and newly divided with more or fewer parts and
extended building services
Some EPC Examples
Shell and Core
If shell only and only gas and electricity meters provided, an EPC is still required on
assumed building services
How can you Reduce Energy
Consumption and Improve your
EPC or DEC?
Reducing Energy Consumption
•
Use the EPC or DEC as a starting point for improvements. Use the Advisory Report
to target areas for improvement.
•
Know your energy usage – read the meters. If you do not have enough meters,
install them! If you do not know how much you are using you will not know if any
improvements being made are actually working.
•
Check usage against benchmark figures
•
Regularly monitor energy use. Form graphs using spreadsheets.
•
Set an overall target energy or CO2 reduction 10%, 20%, 30%??
•
Make someone a Carbon Champion!
•
Review the building and progress annually and review the target. Re-evaluate
priorities . Publicise improvements.
Simple Ideas to Reduce Energy Consumption
 Generate a Management Policy and make someone responsible for it
 Get staff involved and create an awareness campaign.
 Turn lights off when not required – consider lighting control
systems
 Turn off PC’s and other electrical items when not required
 Use energy efficient lighting. T5 fluorescent lamps are the
most energy efficient
 Check operating periods of all plant and equipment. Ensure plant is only used
when required.
 Check set points for the heating, cooling and ventilation systems as part of a
maintenance regime.
Simple Ideas to Reduce Energy Consumption
 Look at improving efficiencies of existing plant and equipment such as boilers,
pumps, insulation, glazing etc. Combine these with refurbishment projects if
possible
 Investigate renewables last as high capital costs and payback periods will be
longer
 Investigate grants for improvements and renewables
If you undertake a major plant replacement and install new energy efficient
systems, carrying out another EPC should show an improvement.
Remember an EPC is based upon the efficiency of the building design, U-Values
and its building services not on metered energy use.
Improvements in energy management will not improve an EPC but it will
reduce your CO2 emissions, energy use and energy bills!!
