Pathway Action 2

Reducing Operational Impacts

Cadogan’s operational carbon emissions come from landlord managed electricity and gas. While this only accounts for 12% of the baseline footprint, it is within direct control so will be reduced as far as possible.

Operational emissions from commercial and residential occupier spaces constitute 58% of the overall footprint, requiring a collaborative approach to reducing emissions. Legislation is rapidly changing in this area, ranging from a push for gas-free homes to tightening MEES requirements, and this is expected to continue.

Chelsea is a challenging environment with historic properties, conservation areas and Listed buildings, but clear energy intensity targets for all new and existing buildings are phased into the pathway to 2030.

Moving To Net Zero

Energy Efficient Retrofit: An extensive programme is underway to survey all assets and programme in relevant works, including (but not limited to) replacing windows, installing insulation and shifting towards low-carbon heating. Following a comprehensive review, costs to implement energy efficiency and low-carbon measures across the Estate are modelled at £75m. Together with a focus on design for performance, there will be an increase in operational performance measurement against energy use intensity targets, exploring the use of operational

performance standards. This move mirrors an industry shift from theoretical to operational measurement and supports a proactive management strategy, using a data-informed approach to minimise unnecessary emissions and tackle best practice behaviours.

Occupier Fit-Out Standards: working in partnership with occupiers, Cadogan sets guidelines for sustainable occupier fit-out: requiring all relevant occupier works achieve an Energy Performance Certificates of B or higher, alongside measures in energy and water efficiency, the circular economy and material reuse. These standards will continue to evolve as industry knowledge develops.

Occupier Engagement: occupier engagement and data sharing is essential to measure performance against targets, share best practice, and facilitate collaboration across Chelsea to reduce emissions. As of 2022, we have actual data covering 36% of occupier space.

CASE STUDY Passivhaus

In 2018-19 Cadogan trialled the EnerPHit standard (Passivhaus for retrofits) on a refurbishment of a mews house, while retaining its charm, heritage character and luxury.

Sitting in the heart of the Hans Town conservation area, 126 Pavilion Road is a nineteenth century stable house, which makes it one of the oldest houses in the UK to meet Passivhaus standards. The refurbishment was so successful that it is one of only 1 percent of domestic refurbishments to be certified as BREAAM ‘Outstanding’.

The refurbishment focussed on superefficient fittings, enhanced thermal insulation and airtightness, and innovative material procurement. The result was a property that the residents love, with improved thermal comfort, enhanced site ecology and biodiversity, and an 85% reduction in energy consumption compared to a traditionally built mews house.

The building has set a new precedent in environmental performance, meeting the demand for a more energy efficiency property in a desirable location. Cadogan is taking the learnings from the project into future residential projects.

WASTE

Reducing waste generation, promoting material reuse and driving the circular economy will also reduce the carbon emissions associated with the transport and management of waste.

WATER Increasing water efficiency and reducing the volume of mains water consumed will have a knock-on effect on reducing the emissions associated with the provision, management and heating of water.

Beyond 2030

Cadogan will continue to improve the efficiency of its building stock, collaborating with partners across the value chain to ensure use of the best technology most suited to Chelsea’s historic environment and collaborating to improve performance.
