Areas of Responsibility (Mechanical & Electrical Services)

This documents aims to set out the lines of delineation between the Landlord and Customer responsibilities for the mechanical & electrical services within our properties. We’ve included generic diagrams and descriptions to help explain how services are provided, and this is very much for an indicative view only.

Customer Handbook

Each property and the services within it vary, as do the terms set out in your lease. Your actual arrangements maybe different to those shown, but this information is provided as a guide to give a clarity of services across the majority of our properties. If you would like an actual representation of the split of services, please contact your Operations Manager who will be happy to help.

Fan Coil Unit - Also know as the FCU, is a unit that contains the equipment required to regulate the air being delivered to your floors. These units will contain (but limited to) a cooling coil within which passes the Customers Chilled Water, the air passes over this coil and is cooled. Filters, to filter the air entering the unit, temperature sensors to monitor the temperature of the air, dampers to vary the volume of air and a fan to vary the speed of the air being delivered directly onto the floor space.

Glossary of Terms

My Property Property specific reports, financials and customer handbook documents.

Cooling Coil – A cooling coil, or heat exchanger is a piece of equipment through which the customers chilled water (CHW) passes within the fan coil unit. As air is drawn across this coil it is cooled before being delivered onto the customers floor.

Dampers – The damper is essentially a valve for air, this device will vary its position to regulate the volume of air that passes through it. These are automatic and control by the Building Management System (BMS)

Heating Coil – The same principle as the cooling coil, however the coil contains hot water, and therefore heats the air that is drawn across it. By varying the temperatures within the heating and cooling coil the system is able to provide the perfect ambient temperature to your floors.

Building Management System (BMS) – Also known as the “head end” the BMS monitors the condition of your floor space through various sensors and regulates the climate in response to changes it detects in order to maintain a set climate condition you have set. Plate Heat Exchanger – Also know as a “HEX” is a piece of equipment that uses plates to transfers heat between two fluids, in our case this is between the our chilled water and your own chilled water while keeping both fluids separate. This “mechanical separation” protects both systems from potentially contaminating the other should effective water treatment not be in place.

Customer Handbook

Isolation Valve (IV) – This is a piece of equipment that regulates, direct and controls the flow of a fluid, in this case it allows use to “isolate” i.e. stop the flow of chilled water entering the plate heat exchanger, to allow the Customer to clean and maintain their system. The isolation value is also the point at which service transfer from being Landlord maintains to Customer maintained. Pump – This is a piece of equipment that moves a fluid by mechanical means, and in this case circulates the chilled water around the Customers systems (also know as the “Tertiary Circuit”) Heat Meter – This piece of equipment measures the thermal energy within a fluid and is used to monitor the difference in temperature between the “flow” and “return” temperatures delivered and received by the Landlord system to measure the heat the Customer is “rejecting”, i.e. your thermal load.

Chilled Water (CHW) – Also known as CHW is the fluid, and is the medium through which heat is transferred around the building. Chilled water is found in both the Landlord System (“the Primary”) and the Customers System (“the Tertiary”). Dosing Pot – This is a piece of equipment that allows you to add chemicals to the fluid, in order to maintain good water quality, preventing bacteria from developing. Expansion Vessel – This piece of equipment regulate the pressure of the fluid, as the system is “closed” i.e. is fully contained and pressurised, the systems pressure will fluctuate due to thermal expansion (changes in water temperature) and the vessel protects the systems for gaining too much pressure.

The Flow – This is the term referring to the fluid as it is delivered to the Customer system from the Landlords system, and will typically be between 6 and 10 degrees. The Return – This is the term referring to the fluid as it is returned to the Landlords system from the Customers system, after receiving the heat load transferred at the plater heat exchanger.
