Pure Offices provide a wide range of private office space to rent in Cheltenham, offering high-standard workplaces for organisations of all sizes. The building has been designed to prioritise flexibility and well-being, with unfurnished office suites allowing tenants to shape the space to their own needs.
Project Requirement
Deloitte LLP occupies the second-floor right-hand wing of the Cheltenham site, consisting of 10 cellular offices, including a mixture of meeting rooms and general staff offices.
The base building is heated via a central boiler plant and radiators throughout. However, Deloitte LLP required an independent system to provide comfort cooling and primary heating specifically for their leased office accommodation.
Spectra Energy Group Delivery
Spectra Energy Group acted as main contractor, completing the project predominantly out of hours to minimise disruption. Our full design and build (D&B) responsibilities included:
Design & System Selection
- Initial design survey of the building
- Selection of a new Samsung VRF air conditioning system
- Design and installation of a bespoke plant area for the external condensing unit
Installation Works
- Full installation of the VRF system including internal and external plant
- Electrical mains power design and installation, including fitting a dedicated kWh meter
- All associated builders’ works for the external condenser compound
Fan Coil Units & Controls
- 9 Samsung compact 4-way cassette fan coil units installed within the cellular offices
- 1 Samsung Wind-Free wall-mounted unit installed where space restrictions required
- Individual room controllers in each office with ±3°C adjustment from a 21°C baseline setpoint
- Installation of a Samsung central controller with a 7-day timeclock and automated stop signals to prevent unnecessary operation outside of business hours
Energy Monitoring
A dedicated kWh meter was installed on the condensing unit electrical supply, giving Pure Offices full visibility of Deloitte LLP’s energy consumption over the year.
End Result / Client Feedback
Deloitte LLP received a new energy-efficient Samsung heat recovery VRF system, delivering:
- COP of 4.2
- ROI of under 7 years
- Expected equipment lifecycle of 20+ years
The client also benefits from a 7-year extended manufacturer parts warranty, providing long-term assurance.
All work was completed out of hours with zero disruption to building occupants. Pure Offices commended Spectra for providing full main-contractor oversight, including:
- Access and egress management
- Fire alarm isolations
- Nightly permits for general and hot works
- Leaving the building clean, tidy and operational each morning
