EPBD, building´s performance and certificates!
For some years, most of us are aware of energy performance certificates: so-called Energy Performance Certificate (EPC), which are used to summarise the energy efficiency of buildings in the European Union. Since January 2009, EU member States have been required to effectively comply with the 2002 Energy Performance of Buildings Directive (EPBD). One of the requirements set by the EPBD is to introduce Energy Performance Certificates (EPCs) which are required to be issued when a building is constructed, sold or let, i.e. as a part of a property transaction.
And the 2018 revision of the European Energy Performance of Buildings Directive (EPBD) aims to further promote smart building technologies, in particular through the establishment of a Smart Readiness Indicator (SRI) for buildings.In the revised Energy Performance of Buildings Directive (EPBD) – which was published on 19 June 2018 – one of the focal points is to improve the realisation of this potential of Smart Ready Technologies (SRT) in the building sector. Therefore, the revised EPBD requires the development of a voluntary European scheme for rating the smart readiness of buildings: the Smart Readiness Indicator (SRI). The SRI aims at making the added value of building smartness more tangible for building users, owners, tenants and smart service providers.
What is the Energy Performance Certificate (EPC)?
It sort of energy certification schemes or energy rating where a building is given a rating between A (very efficient) to G (inefficient). Newly built and majorly renovated buildings are required to have this certification calculated and visually displayed on the building. An Energy Performance Certificate (EPC) is valid for 10 years form the ‘Date of Certificate’ date, which is shown in the top left hand corner of the EPC.
The Energy Performance Certificate (EPC) is a summary of the dwelling’s energy performance. Each element (walls, roofs, heating system, etc.) of the dwelling has been rated between one and five stars based on energy efficiency (one star being least efficient and five stars most efficient). The rating is assessed by the software on the basis of age of property, construction type and features.
What is the Smart Readiness Indicator (SRI)?
In one single score the Smart Readiness Indicator (SRI) classifies the building´s smart readiness in respect of 8 criteria: energy, flexibility, self-generation, comfort, convenience, health, technical follow-up and info to occupants.
This Smart Readiness Indicator (SRI) will allow for rating the smart readiness of buildings, i.e. the capability of buildings (or building units) to adapt their operation to the needs of the occupant. It will also optimize energy efficiency and overall performance, and to adapt building´s operation in reaction to signals from the grid (energy flexibility). The smart readiness indicator should raise awareness amongst building owners and occupants of the value behind building automation and electronic monitoring of technical building systems and should give confidence to occupants about the actual savings of those new enhanced functionalities.
EPBD and smart buildings!
The shift towards ‘smarter’ buildings will bring about multiple benefits to the users of the buildings, including better energy efficiency, health and wellbeing, comfort and convenience.
A greater uptake of smart technologies is expected to lead to significant energy savings in a cost-effective way, while also helping to improve indoor comfort in a manner that enables the building to adjust to the needs of the user.
Smart buildings have also been identified and acknowledged as key enablers of future energy systems for which there will be a larger share of renewables, distributed supply and demand-side energy flexibility.
