The commercial real estate sector is facing increasing demands, with buildings acknowledged as one of the largest producers of carbon globally.
In 2019, the UK Government consulted on how to improve the energy performance of commercial buildings. The sector suggested a long-term plan requiring commercial buildings to meet an EPC B by 2030. An Energy White Paper was published in December 2020, setting out a Net Zero future.
Following further consultation in 2022, the sector is awaiting a response from the Government.
These compliance changes are estimated to impact one million properties accounting for 85% of rented commercial buildings.
Achieving these standards will require a considerable investment in insulation and mechanical and electrical services in a sector which knows little about how assets perform.
As part of the roadmap towards Net Zero by 2050, the Government proposed an interim milestone of EPC C by 2027. However, the property sector has not received this well.
The EPC system measures a building’s potential efficiency, not energy consumption. There is typically a significant difference between assessed and actual, often referred to as the performance gap.
Building performance depends on how energy is managed, maintained and used.
Landlords are aware of total energy consumption via their annual utility bill; however, monthly bills provide little detail.
With changing space utilisation following the pandemic and increases in wholesale energy costs, building operators need to understand their buildings more.
The Government has set out plans to introduce a framework for assessing energy use in commercial buildings above 1,000m² with published ratings.
The rating system will be similar to NABERS (National Australian Built Environment Rating Scheme), providing a trusted and consistent performance measure.
Landlords will be required to submit annual energy use data to the rating administrator, who will provide a rating shared in the building and online.
The Government plans to introduce the rating in three phases over the next ten years, with the office sector first.
Increasing compliance requirements and demand for data have led to increased adoption of digital twins as landlords look to optimise the energy performance of buildings.
Twinview provides an easy-to-implement platform allowing users to view their property data in one place.
