The Hilton Hotel 791 room London Gatwick Airport Hotel is located next door to the South Terminal. Integrated Service Modules (ISMs) containing passive chilled beams along with radiant heating panels were specified in corridors linking the original hotel building with two new additional wings. In total nearly 170 metres of ISMs and radiant heating panels were installed over six floors.

The ISMs were chosen in order to combat the solar gain in the highly glazed corridors and to supply both up and down-lighting to the space. The radiant heating panels were located above and to either side of the ISMs providing radiant heating to the corridors.

The complete heating and cooling system was manufactured to complement the design of the extension and modern glass walkway. Radiant heating panels and ISMs are available in a wide range of shapes and sizes to meet specific aesthetic needs.

Passive ISMs provide up to 400 W/m of cooling and work using natural convection; as hot air rises it is cooled before returning downwards. The higher the level of solar gain, the higher the amount of cooling provided.

Radiant heating panels are capable of providing up to 500 W/m of heat output and use radiation as opposed to convection to heat the space, glazing and people using the corridor.

ISMs are energy efficient and use the relatively high supply water temperature of 14ºC. Their energy efficiencies can be increased even further when combined with free cooling or ground sourcing systems.

In addition to luminaires ISMs can feature other building services such as voice and data cabelling, smoke detectors, sprinklers, PA systems and Passive Infra-red (PIR) sensors. Not only does combining building services into one module provide protection it can also leave soffits uncluttered, which can allow a building’s fabric to be exploited for thermal mass heating and cooling. This process is termed Fabric Energy Storage by the Concrete Centre and has a heating and cooling potential of up to 25 W/m².

Radiant heating panels and passive chilled beams contain no moving parts and require little or no maintenance. This means that maintenance scheduling and both the associated costs and system down-time are reduced.

ISMs and radiant heating panels are manufactured in a factory controlled environment and can be pre-tested before delivery to site. Both systems are easy to install and delivered to site as required, reducing the on-site labour costs, storage requirements and accidental damage levels.
