Port Centre Project Port Centre Project Boiler House Refurbishment The boiler house refurbishment involved the removal of 2 oil-fired combi boilers, LTHW pumps and pipework, MCC and controls panel and associated pneumatics.

The upgrade included the installation of 2 x 286 kW modulating and condensing gas-fired boilers; 4.5 kWe, 12.5 kWth microChp with condenser module and 1500 litre buffer vessel; LTHW pumps, pipework, valves and commissioning sets with lagging; DHW calorifier; new MCC and controls panel; extensive electricity, gas and heat metering; ancillary equipment.

Advanced control strategies were developed to maximise boiler efficiency using direct modulation and weather compensation. Using advanced control also allowed for the CHP to be used as lead heat generator, then charging the buffer vessels when there is no heat load, then discharging the buffer vessel when the heating is first started in the morning, while avoiding charging of the buffer vessel during the day. The CHP (and boilers if required) are used to maintain domestic hot water at temperature when there is no space heating load, while avoiding wasteful cycling or heat loss into the space heating circuits.

Ventilation Controls Retrofit The ventilation controls retrofit included the removal of pneumatic controls for the Variable Air Volume {VAV) boxes in offices, and installation of BMS control units and electro actuators on the VAV boxes and room temperature sensors. Whereas before office temperature control was erratic, each office is now monitored and controlled via the BMS, and the temperature control of the main AHU can be harmonised with the requirements of the offices.

Port Centre Project Port Centre Project Energy Performance Contracting Element

The project was delivered through an Energy Performance Related Payment (EPRP) model.

For the boiler house refurbishment the standard NEC3 Engineering & Construction Contract was used but modified so that, the consultant and the main contractor each guaranteed separately to the client that the project would achieve a 15% energy-efficiency improvement in fossil fuel use. If this guarantee was not achieved, each would lose 7.5% of their respective contract values. To avoid excessive impact of two retentions on the contractors cash flow, on completion the retentions were combined into a single amount of 7.5% both pending completion of all defects and measurement and verification of guaranteed savings. Once savings were verified the retention fell to 2.5%, i.e. to cover the Works Retention only.

The ventilation controls retrofit involved a pain/gain share arrangement which was placed through a standard Purchase Order arrangement – performance was measured by evaluating electrical savings. If 100% of the target electrical kWh savings are achieved, the parties receive 100% of their respective fees. For each 1% of additional savings, the consultant and contractor receive a bonus of 0.5% of their fee, up to a maximum of 5%. For each 1% savings falling short of target, the consultant and contractor incur a penalty of 0.5% of their fee, up to a maximum of 5%.
