You Won’t Believe the Shocking Carbon Impact of Office Renovation vs Demolition!





Title: The Benefits of Renovation and Refurbishment in the Commercial Property Sector

Introduction

In the world of commercial properties, the need for renovations and refurbishments has gained significant importance. This article explores the environmental and financial advantages of opting for renovation over demolition and rebuilding. We will also look at a specific case study involving the dispute over 458 Oxford Street in London, owned by Marks and Spencer. Additionally, we will discuss the increasing emphasis on green credentials and energy efficiency standards in the commercial property sector.

The Dilemma of Developers

The dispute surrounding 458 Oxford Street sheds light on the dilemma faced by developers when deciding between rebuilding and renovating commercial properties. Activists are fiercely against the proposed demolition, citing the cultural significance of the Art Deco building and raising environmental concerns. A decision on whether to proceed with the demolition is expected soon.

According to Tom Scott of advisory Construction Carbon, the difference between rebuilding and renovating can result in a carbon emissions difference of over 30,000 tons of CO₂. This staggering gap is equivalent to 100,000 transatlantic flights. The calculation assumes that the carbon footprint of renovation would amount to 9,000 tonnes, compared to the developer’s estimate of 40,000 tonnes of CO₂ for a new building, which includes demolition and removal.

The Financial Incentive for Demolition

From the owner’s perspective, the appeal of tearing down a building lies in the possibility of replacing it with a more valuable one. In the case of the Marks and Spencer redevelopment project, the finished building could potentially be worth nearly £300 million more, factoring in construction costs, according to Tom Scott.

However, retrofitting an existing building can result in a smaller floor plan due to factors such as additional ducting. This is something developers must consider when weighing the financial benefits.

The Green Credentials Advantage

In recent years, green credentials have become a top priority for developers in the commercial property sector. Tenants are increasingly demanding environmentally friendly spaces, and energy efficiency standards have been implemented to meet these expectations. British Land and Land Securities have seen a 90% higher employment rate due to their commitment to environmental criteria. Landlords who fail to improve the environmental performance of their spaces risk being left with stranded assets.

When it comes to commercial properties, concrete, steel, and plastic not only cost money but also contribute to carbon emissions. Renovation and refurbishment offer a greener and less expensive alternative to demolition and rebuilding.

Case Study: The Dispute over 458 Oxford Street

The dispute over 458 Oxford Street showcases the complexity and significance of choosing between demolition and renovation. This mixed office and shop site, owned by Marks and Spencer, is an Art Deco building with cultural value. The debate revolves around preserving the building’s historical significance while addressing environmental concerns.

The carbon emissions comparison between rebuilding and renovating 458 Oxford Street reveals a massive difference. Construction Carbon estimates that renovating the building would result in 9,000 tonnes of CO₂ emissions, while a new building, including demolition and removal, would emit approximately 40,000 tonnes. Tackling such disparities is crucial when considering the overall carbon footprint of the building stock.

The Advantages of Renovation and Refurbishment

1. Lower Carbon Footprint: Renovating and refurbishing existing buildings significantly reduces carbon emissions compared to constructing new ones from scratch. This is due to the energy and resources required for demolition and the creation of new materials.

2. Cost-Effective: Renovation and refurbishment often prove to be more financially viable than demolishing and rebuilding. Developers can save on construction costs by utilizing existing structures and materials.

3. Preservation of Cultural Heritage: Many commercial properties hold historical and cultural significance. Renovation and refurbishment allow for the preservation of these valuable assets, maintaining the character and charm of buildings.

4. Reduced Waste: Demolishing a building generates a significant amount of waste that ends up in landfills. In contrast, renovation and refurbishment focus on repurposing existing materials, contributing to waste reduction and sustainable practices.

The Role of Green Credentials in Commercial Properties

Green credentials have become a paramount consideration in the commercial property sector. Developers who prioritize environmental sustainability attract tenants looking for energy-efficient spaces. This increasing demand is reflected in higher employment rates for companies operating in green-certified buildings.

Moreover, government regulations and energy efficiency standards now require commercial properties to meet certain criteria. This push towards sustainability further drives the need for renovation and refurbishment, as it offers an opportunity to enhance a building’s environmental performance.

Conclusion

In summary, the benefits of renovation and refurbishment in the commercial property sector are undeniable. Not only does it contribute to lower carbon emissions and reduced waste, but it also allows for the preservation of historical and cultural assets. Developers who prioritize green credentials and energy efficiency standards stand to gain financially and attract environmentally conscious tenants. The case of 458 Oxford Street exemplifies the importance of choosing renovation over demolition, considering the environmental and cultural significance of existing buildings.

Summary

Rather than simply tearing down and rebuilding commercial properties, renovation and refurbishment offer an environmentally friendly and cost-effective alternative. According to a case study involving 458 Oxford Street in London, renovating the building produces significantly lower carbon emissions compared to constructing a new one. Emphasizing the importance of green credentials, developers who prioritize energy efficiency standards attract tenants and achieve higher employment rates. Renovation and refurbishment also contribute to waste reduction while preserving valuable cultural heritage. Choosing renovation over demolition is a crucial step towards decarbonizing the building stock and creating sustainable commercial spaces.

Concrete, steel and plastic cost money and carbon. Time adds another constraint. In the UK, landlords want to improve their housing stocks as remote working weakens the demand for office space. Renovation and refurbishment offers a greener and less expensive alternative to demolishing and rebuilding.

The dispute over 458 Oxford Street in London, owned by Marks and Spencer, highlights the dilemma of developers. Activists are vehemently against the proposals to tear down and rebuild the mixed office and shop site. At stake is the cultural significance of the Art Deco building as well as environmental concerns. A decision on whether to proceed with the demolition is expected by the end of the month.

The difference between rebuilding and renovating amounts to more than 30,000 tons of CO₂, according to Tom Scott of advisory Construction Carbon. This is the equivalent of 100,000 transatlantic flights. The calculation assumes that the carbon footprint of the renovation would amount to 9,000 tonnes. This compares to the same developer’s estimate of 40,000 tonnes of CO₂ for a new building, which includes demolition and removal.

Two dual-scale graphs showing new construction versus refurbishment of the M&S building at 458 Oxford Street.  The first charts show the cost of construction (millions of pounds) versus carbon (tonnes of CO2) for a refurbishment and new build.  The second chart shows the asset valuation (million pounds) and rental yield (%) for refurbishments and new builds.

For the owner of a building, the appeal of tearing it down lies in the possibility of putting a more valuable one in its place. Conversely, retrofitting can mean a smaller floor plan due to factors like additional ducting.

If the Marks and Spencer redevelopment project goes ahead, it will have more extra floors, including two in the basement. Adjusted for construction costs, the finished building could be worth nearly £300m more, Scott thinks.

Smart developers put green credentials at the top of the list, notes Simon Sturgis of consultancy Targeting Zero. Environmental criteria have become an essential feature of the privileged space, driven by tenant demand and the new energy efficiency standards. This is reflected in 90% higher employment rates at British Land and Land Securities. Landlords risk being left with assets stranded if they don’t improve the environmental performance of their spaces.

Decision-making on old office blocks involves trade-offs. Achieving high energy efficiency standards is easier when you start from scratch. But retrofitting an existing building is usually much less carbon intensive than rebuilding. This should steer the debate on how best to decarbonise the building stock.
