Energy performance certificates for buildings became a legal requirement as of 6 April 鈥� sort of. Neither the state nor the property sector seemed well prepared as the deadline approached, and at the eleventh hour the government capitulated to pressure from building owners by fudging the deadline.

The same may well happen for the next phase of the process, display energy certificates (DECs), which are supposed to be required in all public buildings from 1 October.

The final version of the computational software for energy assessments, SBEM, has only been available for downloading since the beginning of April. And there remains concern in the property sector and among services engineers about whether there are enough assessors to tackle the expected demand.

At this point, only buildings of more than 10,000m2 need an EPC, when they are constructed or up for sale or rent. But by 1 October, all buildings will need a certificate in these circumstances. This is also the date from which public sector buildings need a DEC to show how much energy they consume.

An EPC rates only the building and its potential to conserve energy and reduce carbon emissions. A DEC is an energy consumption rating that lets the public know how efficiently a public building is being run.

Some heavy lobbying from owners of large commercial buildings forced the government to ease the deadline for EPCs. Originally, if a building was for sale on or after 6 April, it would have needed an EPC right away. But now buildings already on the market only need an EPC when the contract is exchanged, or by 1 October, whichever is sooner.

Lack of action

A CBI/GVA Grimley Corporate Real Estate survey published in January found that half of the 178 property owner respondents were either unaware of the EPC requirement or had taken no action towards getting one.

Paul Edwards, head of sustainability with developer Hammerson, said EPCs and DECs would make tenants wiser when it comes to discussing rents. It remains to be seen if many tenants will want the lowest rated buildings; landlords may be forced to upgrade. More worrying, he said, is the confusion about where all the assessors will come from and what will gain a building an A-rating versus a G-rating: 鈥淭his is still a black box to us.鈥�

Market gears up

The requirement for certificates is a boon for building services engineers, given that hundred of thousands of buildings will need assessments. The market is slowly gearing up for what is expected to be a gradually increasing demand for both EPC and DECs, according to some consultants. To this end, organisations such as CIBSE have been offering government-accredited training courses to certify assessors as qualified to carry out EPC and DEC inspections. CIBSE estimates it had trained about 100 assessors ready for 6 April.

CIBSE has more than 700 low carbon consultants on its register and expects many of these will take the top-up training to become an assessor. Other organisations, including the RICS and BRE, also offer training.

Complaints about late availability of the SBEM software, originally created for Part L of the 好色先生TV Regulations, may be misplaced. Paul Davidson, director of sustainable energy at BRE, and head of the team that developed the software, said a version has been available since mid-February.

鈥淭here鈥檚 not much change from the Part L configuration,鈥� he said. 鈥淵ou can modify the EPC鈥檚 accompanying recommendation report, and the programme is also flexible.鈥�

An important feature, said Davidson, is that the process leaves an audit trail of where the information came from and why recommendations were made based on that information.

Software for DEC assessment is about to go through tests with users, from information input to certificate production, said Faber Maunsell associate director, Lionel Delorme, who is overseeing its development on behalf of the DCLG. In March about 20 organisations, including the Royal Albert Hall, MoD, Natural History Museum and the Local Government Association, tested the software.

鈥淲e are going through feedback with the DCLG now and are aware that it must be finished quickly to give people as much time as possible before the 1 October deadline,鈥� he said. 鈥淚t might that we can make the software available while the end-to-end pilots are taking place.鈥� Delorme believes the final version of DEC software should be available towards the end of May at the latest.

The down-to-the-wire launch of SBEM has meant many training and certification organisations are still developing their own interface software for the certification process. Glasgow-based IES has just launched its Virtual Environment package but said its DSM version (dynamic simulation model) 鈥� needed for the most complex buildings 鈥� will not be available until next month.

Hywel Davies, CIBSE鈥檚 technical director, believes about 100,000 buildings will get their EPC within the first year. But he doesn鈥檛 foresee a shortage assessors for EPCs and DECs. 鈥淓PCs are being phased in from this month so there is not likely to be a big rush. Also, many public authorities are already gathering data on energy consumption so they can be ready for 1 October when the DEC must be displayed.鈥�

Some public bodies might eventually pay to have their own staff trained to become assessors, said Davies. 鈥淭hey will probably get their own staff certified because they will know their own buildings well, the equipment and its maintenance history.鈥�

He doesn鈥檛 believe having employees assessing their own building will be a case of a police force being asked to investigate itself: 鈥淚 really don鈥檛 think so. The way the assessment is set up means there is very little room for fiddling.鈥�

Short route to accreditation

The Department for Communities and Local Government is responsible for implementation of the EU鈥檚 Energy Performance of 好色先生TVs Directive, which stipulates the need for certificates. It is confident enough assessors will be ready from day one.

A spokesman said the vast majority of potential energy assessors for larger buildings are experienced practitioners who will need only a few days of training for accreditation. 鈥淭raining courses for those who will assess simpler buildings have commenced and training courses for those wishing to produce display energy certificates are planned for April,鈥� he said.

It remains to be seen how many assessors are trained, said Nick Carter, director of building services at consultant Gifford. 鈥淭raining and registration for an assessor will cost around 拢1000,鈥� he says. On top of that is the cost of lost time and money, say around 拢5000, on project work while the training is undertaken. (A two-day CIBSE EPC course and assessment costs 拢425 plus VAT.)

Nonetheless, Gifford plans to have six assessors because, as with Part L, clients will expect the consultancy to do an EPC for their new buildings. Carter believes there will eventually be enough assessors because of all the professional organisations offering certification programmes.

鈥淏ut whether we get much involved in certifying our people will depend on market demand for EPCs and the number of certified assessors,鈥� he said. 鈥淲hat we at Gifford don鈥檛 want is to be having one of our good engineers sucked into doing a lot of EPCs.鈥�

The DCLG says the market will decide what an assessor can charge for the service, and this will probably depend on the size of building.

Davies agrees: 鈥淯ntil some assessments are done, we won鈥檛 know. But I imagine those organisations that have kept good records of maintenance and energy consumption could be paying less because there is less leg-work to be done by assessors.鈥�

Getting the data could be the Achilles heel for public authorities. If the government鈥檚 own statistics are to be believed, building services consultants could be very busy helping public authorities gather energy information for DECs in the run-up to the 1 October deadline.

A National Audit Office report in November found that 265 of 877 buildings reviewed had no energy consumption figures. Also, 300 of the 877 were unable to provide the figures for the proportion of energy they obtained from renewable resources.

Is the DEC deadline unrealistic? At least one consultant BSj spoke to believes it is, and that it may well be postponed.
