• BCC – Where we are

EPBD Elements - Certification

• Domestic - HIP Energy Ratings,

• Commercial (new developments and selling/letting of existing) = Energy Performance Certificates (EPCs)

• & for public buildings = Display Energy Certificates (DECs)

Display Energy Certificates

What buildings must display a DEC building and by when

• either a public body currently OCCUPIES or ‘by institutions providing public services to a large number of persons and therefore frequently visited by those persons

• >1000m2

• Examples – Schools (inc. BSF and PFI), libraries, police stations, courts, LA offices, leisure centres, hospitals and university buildings,

• Exceptions – places of worship, car parks• Must be displayed by October 2008!!

What if you don’t display a certificate?

• Trading standards can fine you £500 for non display of a DEC

• £1,000 fine for not being able to produce an advisory report– Expect some leniency

in 1st year

2 parts of DECs

1. The Certificate itself. (based on actual reads not estimated – will

accept estimates in 1st year)

2. An Advisory Report. Needs to be updated every 7 years.

How do you produce a DEC?

1. Choose an accreditation scheme2. Identify buildings requiring a DEC i.e. over a

1000m2 3. Who’s responsible? i.e. it’s the occupier who is

responsible NOT the owner 4. Get your accredited assessors to produce an

advisory report5. Produce the certificate and upload to accredited

body for uploading to national register6. DEC to be done every year

Things to think about

Multiple buildings on one site – floor areas

Multiple buildings on one site - metering

Interesting buildings!

Florence Brown Community School

BCC

• Producing a list of buildings requiring a DEC• Identifying for each building:

• Floor areas• Meter locations• Special areas e.g. Server rooms, CCTV rooms?• Calculating splits

– Including for multifunctional buildings• Monthly Meter reading plan – AMR or Customer/web based

• Waiting for accredited bodies to come on stream• Tender for DEC uploading and training staff

• Waiting for:• DEC software to produce advisory reports and certificates• Benchmarks for building types

DEC Calculation Tool

• 30+ Benchmarks

How it works

• UPRN created by accredited assessor for each building/part of building

• Survey of building and energy use• DEC and AR Produced• DEC and AR uploaded to Commercial

Register• Official DEC and AR ready for printing and

display

Current State of Play

• 43,000 public buildings to be certified by 1st October 2008– Very few with a DEC (less than 100)– Very few trained and accredited energy

assessors– Software only just finished

• Floor areas

• Unconditioned areas

• Occupancy

• Separable Energy Uses

• On site renewables (must be metered)
