Retrofitting buildings for a sustainable future

More recently, the government has indicated a potential review of the regulations and timelines to ensure fairness for both landlords and tenants. With increasing commercial floor space needing EPC renewal within the next 12 months, there is mounting anticipation surrounding the government’s decisions. The Department for Energy Security and Net Zero has confirmed its intention to revisit the EPC standards. However, with less than a third of commercial space currently meeting this target, many in the industry are calling for clearer guidance and a more realistic timeline for compliance. Certainty and clarity on what is needed could actually accelerate the pace of retrofitting as it provides clearer direction.

Calls have also emerged for the government to take a broader view, considering not just the EPC targets, but also the state of national grid infrastructure, the legal framework, and whether EPCs are the most effective tool to push the built environment toward net zero.

The imperative for retrofitting extends beyond regulatory compliance. It speaks to a deeper economic reality, with changing market dynamics and evolving consumer preferences. Traditional buildings that are not fit for purpose risk becoming obsolete relics of a bygone era. Retrofitting offers a lifeline and an alternative to the prime offering, a chance to breathe new life into these structures, unlocking their latent potential and ensuring their relevance in an ever-changing landscape. 

Recent seismic shifts in office occupancy levels, precipitated by the global pandemic, have reshaped the commercial real estate landscape. Occupier demand for secondary quality offices has fallen considerably, with annual take-up for these offices dropping by approximately one-third since the COVID-19 pandemic. We are acutely aware of the legal ramifications of this paradigm shift, from lease agreements that are flexible to allow for modernisation of services, compliance with green covenants, and the effect on property valuations. Retrofitting offers a clear pathway forward, providing a means to adapt and repurpose existing structures to meet the evolving needs of a dynamic workforce.

The retrofitting of offices is gaining momentum, as evidenced by the City of London Corporation approving a record number of retrofitting applications last year, accounting for half of all such applications across London. The costs associated with comprehensive retrofitting strategies are estimated to be between £70 and £110 per square foot, yet the potential benefits, including rental and sales premiums for sustainable and well-certified buildings, are significant. Sustainable offices with strong environmental accreditations can command a rental premium for BREEAM 'Outstanding' certifications compared to uncertified offices.

In addition to retrofitting, repurposing office spaces into alternative uses such as hotels, residential units, or student accommodation presents a viable solution to the obsolescence challenge. London, being a major tourist destination, has seen numerous office-to-hotel conversions, while the demand for housing and student accommodation remains high.

In conclusion, the drive for retrofitting buildings in the UK transcends mere regulatory compliance—it is imperative that we create a future defined by sustainability and resilience. Through retrofitting and repurposing, we can reshape our cities and redefine our legacy for generations to come.
