114 St Martins Lane, London
114 St Martins is an office building located in the West End of London. Situated in the heart of Covent Garden, the property consists of 7 Floors.
The building was originally serviced through a VAV system. The AHU for the VAV system utilised a Chilled Water Condensing unit and a Boiler Plant as a means of providing conditioned air to each of the floors.
Sowga were instructed to replace the existing Chiller condensing unit, Boiler Plant and VAV AHU.
Main Considerations:
- Replace original heating and cooling systems with Daikin VRF system
- Install & integrate Daikin iTouch Management system with BMS
- Replace non-conforming existing assets
Key phases included:
- Daikin VRF system installed as a means of providing heating and cooling to tenants floors.
- System was controlled through a Daikin iTouch Manger. The iTouch Manager was interfaced to the Building Management System through a synapsys gateway.
- New AHU was installed which used a DX coil and the new heating plant as a means of providing tempered Fresh air to the floors
- Each Floor was split into individual system consisting of an external condenser and between 10-11 FCU's.
- Each system was metered from the main control panel to allow billing to each individual tenants space.
- The existing CWS tank was replaced with a reduced capacity tank to increase movement of water.
- All Non compliant Electrical Distribution Boards were replaced. This amounted to 8 in total.
- The existing MCCB was replaced to conform to current standards.
TOP LINE RESULTS:
- Increased asset compliance and conformity
- Improved tenant wellbeing due to tempered fresh air now being fed to floors
- Increased building performance & control
