When CitiGroup were opening an office in Belfast's new Titanic Quarter their consultants Semple McKillop were instructed to provide an innovative and efficient system to heat and cool the building with an emphasis on low Co2 emissions.

After examining a number of possibilities a Gas Fired Heat Pump system was chosen. This equipment which combines the low Co2 emissions of a gas fired engine with the Coefficient of Performance of a heat pump met the client's criteria.

The four outdoor units serving 50% of each floor of the two storey building are rated at 60KW output when heating. The same units can provide 56KW of cooling when it is needed. With the building geared for 24/7 operation both capacities were required.

BL Refrigeration and Airconditioning Ltd supplied and installed the specified plant.

Phoenix Gas provided the gas supply from a line which they are sure will serve many more of the new buildings under construction in the Titanic Quarter.

The system installed utilizes indoor ducted units with careful attention to detail insuring an even distribution of conditioned air, maximum working height and the industrial look of exposed services. The internal crane of the original Harland & Wolf building has been retained and painted in the familiar yellow of Harland and Wolf's iconic cranes Sampson and Goliath.

The building itself forms part of the ever expanding Titanic Quarter which is revitalizing the old "shipyard" and changing the skyline of Belfast.

Installed Equipment

Outdoor 4 off 60Kw gas fired heat pumps.
Indoor 32 off Ducted direct expansion units, various capacities.

Floor area Overall approximately 2500m2

The payback on the increased cost of the gas fired units versus the electric version was calculated to be under 3 years.
