2 Description Of Existing Services

2.1 Building validation & restack works 2012 A re-stack of floors 3-9 and re-balance of the main HVAC plant was undertaken in 2012. The contractor can use this information however we cannot guarantee the accuracy.

2.2 Landlords Heating Plant Heating is provided by a central Low Temperature Hot Water (LTHW) system, served by three gas-fired boilers located within basement level 1 boiler plant room. There are four main distribution circuits plus a common primary circuit. Each circuit is served by duty/standby pump sets as follows:

• LTHW primary

• LTHW constant temperature Fan Coil Unit (FCU) circuit.

• LTHW constant temperature Air Handling Unit (AHU) circuit.

• LTHW constant temperature 24 hour circuit.

• LTHW variable temperature radiator circuit.

2.3 Landlords Cooling Plant Cooling is provided by a central Chilled water (CHW) system, served by two air-cooled chillers located at roof level (9th floor). There are two main landlord distribution circuits plus a primary circuit for each of the chillers.

Each circuit is served by duty/standby pump sets as follows:

• CHW primary.

• CHW constant temperature FCU circuit.

• CHW constant temperature AHU circuit.

The 24 hour cooling is by a CHW system, served by an air-cooled chiller located within basement level 1 plant room 27. There is one main distribution circuit plus a primary circuit for the chiller. Each circuit is served by duty/standby pump sets as follows:

• CHW primary.

• CHW constant temperature 24 hour circuit.

The 24 hour unit provides environmental conditions within the following specialised areas:

• Archive AHU 4.

• Communications room AC1.

• Patch rooms up to third floor level.

All the above systems are installed in a two pipe arrangement and are each pressurised.

2.4 Landlords ventilation plant The main air conditioning/ventilation system comprises of a number of central supply and extract systems, served by Air Handling Units (AHU’s) which are located within various areas of the level 1 basement. The main AHU’s serving the office accommodation including the 2nd floor accommodation is as follows;
