Operating at the intersection between high-quality customer experience and expert energy efficiency, the collaboration between our Welcome and IBOS teams has delivered cumulative savings of £3m for 10 properties.
Across space covering almost 1.5m sq. ft, the interface between the two teams has seen an average energy saving of 23% across the 10 properties managed by Welcome where IBOS is installed – this translates to 10,594,872 kWh saved, enough to power the equivalent of 1,060,000 UK households for one day.
Monika Newton, Partner and Head of Workman’s Welcome service, said:
IBOS has enabled us to enhance our service through technology. Increasingly, we are finding that occupiers are committed to improving the environmental performance of the buildings where their employees are based. For Gen Z employees especially, this is becoming a reason to come into the office, and even a reason to choose an employer.
James Hallworth, Partner and Head of Building Technology at Workman, said:
As the world moves towards more sustainable energy practices, understanding and optimising energy efficiency in buildings is predicted to play a vital role in achieving environmental goals. Owners within our Welcome-managed portfolio are at the vanguard of this shift, with a drive to offer the highest quality office experience to the most selective and forward-thinking occupiers.
See some of our standout achievements, where the power of IBOS has multiplied our Welcome service:
At Anchorage – a landmark waterside building situated in the heart of Salford’s international business quarter – our teams have achieved a 51% reduction in energy consumption, which translates to £293,073 in cost savings to date. The property has recently undergone refurbishment, including infrastructure upgrades with high-speed internet, modern VRF heating and cooling system, all integrated with IBOS technology.

At 100 New Oxford Street – a mixed-use building in central London – we have delivered a 33% reduction in energy consumption, or £507,827 in cost savings to date. The team integrated IBOS into the whole building’s infrastructure, including the Building Management System (BMS), central plant, chillers, boilers, Air Handling Units (AHUs), Low-Temperature Hot Water (LTHW) systems, and extractor fans. A new metering network was installed, incorporating sub-meters connected to the IBOS platform designed for comprehensive energy data collection throughout the entire building. Meanwhile, IBOS wireless indoor air quality sensors were installed, enabling real-time air quality monitoring and immediate response capabilities.

At Republic’s Import Building – office and mixed-use space in East London – our teams have realised a 22% reduction in annual energy consumption, which translates to cost savings of £780,242 to date. Building owner Trilogy said: “To achieve our EPC and Net Zero pathway goals, Trilogy recognises that significant opportunities lay in the optimisation of building controls to ensure equipment is operating efficiently, and at appropriate times. By implementing IBOS, Trilogy continues to maximise efficiencies, aligning to Net Zero interventions within our sustainability strategy.“

We know that today’s occupier is looking for a sense of place and community, so that the offices managed by our Welcome service become buildings that occupiers and their employees want to be in.
This means buildings that benefit from excellent customer service, as well as optimised energy efficiency, attract occupiers who are focused on the overall environment, while providing a richer experience for their employees.

Mott MacDonald has signed up for an additional 20,000 sq. ft at its existing London headquarters, at Addington Capital’s Workman-managed 10 Fleet Place, as reported by React News.
The engineering giant has signed a lease for the fourth floor of the 186,000 sq. ft 10 Fleet Place. Overall, the global consultancy will have space totalling circa 60,000 sq. ft in the building, on leases running to 2040.
Occupying a popular mid-town / City location, 10 Fleet Place has been managed by Workman LLP under its Welcome Offices service since 2016. It is asset-managed by Addington Capital, which steers the property on behalf of Hong Kong-based Crosby Group, owner of the building since 2015.
Space availability at 10 Fleet Place during 2023 provided Mott MacDonald with the opportunity to fully refurbish the first and second floors without having to relocate staff. They adopted a phased approach, transferring employees into spaces once completely refurbished. Since signing their new lease, the engineering giant is currently working on refurbishing the fourth floor in keeping with its other spaces.
Monika Newton, Partner at Workman, and Head of the firm’s Welcome Offices team said: “This achievement is a true testament to the incredible collaboration between outstanding property management and asset management teams, along with the landlord’s investment in the building. Together we have delivered exceptional customer service, not only to attract new occupiers but also to retain our existing ones.”
Workman’s intelligent building optimisation system (IBOS) was installed in 2022 providing smart technology to optimise building plant and manage energy efficiency across all floors, which has delivered significant savings on electricity and gas. Indeed, IBOS has delivered a saving of 719,040 kwh, translating to £373,887 based on current contract rates.
Monika said: “We are working with Mott MacDonald and other occupiers to achieve their ESG aspirations, and know that tools such as IBOS have previously proven to help our clients achieve their corporate aspirations regarding delivery of carbon and cost savings.”
A substantial phased refurbishment programme has recently completed at the building, including new end of trip facilities, reception upgrade and new external signage (pictured). Occupiers at 10 Fleet Place benefit from top-of-the-range facilities, including 18 showers (fully refurbished in 2023), 191 bike racks, 24 folding racks and 168 lockers, secure underground parking facilities, six newly installed EV charging spaces and a Platinum WiredScore certification. The building also benefits from transport links including the Elizabeth Line at Farringdon.
Now 96% let, 10 Fleet Place is also home to occupiers including Interpath Advisory, CNBC and law firm Hogan Lovells.
Remaining office and retail space is all under offer.
