Simplifying Display Energy Certificates
EIC discusses the purpose behind DECs, the benefits they offer and how the EIC carbon team can help you secure one.
What is a DEC?
Display Energy Certificates (DEC) have been a required document in public buildings since 2012. While some structures are exempt, those with floor space of less than 250m2, larger buildings fitting certain criteria must comply. These are properties that are occupied by a public authority and frequently visited by the public.
The certificate summarises the energy performance of the building based on criteria known to affect energy demand and usage. These criteria include the type of building under assessment, its total floor area and fuel use.
Accreditors then measure this data against specific benchmarks to determine the building’s overall energy performance. Newer buildings are more likely to have consolidated record-keeping on a building and their HVAC. However, older properties may need to collate this data from various departments and archives.
Since data might be stored in a multitude of locations and formats, this process can be complex and time-consuming. However, the more intelligence that can be sought, the more valuable the DEC becomes in its ability to help identify sources of energy waste.
What are the benefits?
The primary benefit of a DEC is to provide a litmus test for the current energy efficiency of a building. This data can then guide improvement strategies for the structure’s utility usage, thereby reducing their demand and subsequent cost. Only accredited assessors are qualified to analyse and deliver DECs. Part of their service is identifying opportunities for improvement and providing guidance on how to implement these improvements as well.
DECs also communicate your commitment to carbon reduction to visitors, due to the requirement to display them prominently. As consumers become more aware of the effect of their spending habits on the environment, it will dictate the businesses they are willing to interact with. A DEC demonstrates dedication to reduce to or maintain an efficient rating for the building.
Do you need a DEC?
If you are a public authority receiving frequent public visitation, with usable floor space in excess of 250m2, then you will need to display a DEC. The validity period of these certificates does vary depending on building size. The DEC of buildings between 250m2 -1000m2 remains valid for 10 years. However, buildings larger than 1000m2 must renew every year.
Those in need of a DEC or those looking to renew would benefit from shopping around. Ideally looking for a compliance specialist that can offer them the most value with their service.
EIC offers an end-to-end DEC acquisition, starting with a comprehensive site survey if a lack of available data necessitates it. A copy of the accreditation documents will be forwarded to your organisation once the process is complete.
The EIC team pride themselves on providing relief from the complex process of accreditation, allowing business leaders to focus on their own clients and services. To date, EIC has produced over 5,000 DECs and currently manages the renewal process for over 600 sites.
Each of EIC’s EPBD delivery team, have worked within the schemes since their inception, thereby bringing trusted and reliable expertise to your project.
The EIC carbon team provides various compliance services including major carbon-legislative guidance and all EPBD services (EPCs, DECs, TM44). Since these accreditations work in tandem, and share data sets, getting them under one roof can save you some time. While each of these carbon services can be found on EIC’s trusted compliance page, those seeking the DEC offering specifically can find it here.
