Hotels are unusual buildings, in that their occupants have a big influence on how they are operated. Unlike office workers, hotel guests won’t be ignored if their room is too cold or the hot water doesn’t work.
For hotel managers, unhappy guests complaining about the building services can result in lost revenues. In today’s economic climate where many hotels have seen guest numbers fall, this simply isn’t an option.
So in hotels building services really do have an impact on the bottom line. The problem is finding a balance between energy-efficient operation and occupant comfort.
These issues are all covered in this special “MBS Focus” devoted to hotels. There is a wealth of interesting ideas and hard experience in this special section of our web site. Click on any of the items on this page for more.

S&S Northern supplies another service station
S&S Northern has completed its third project with Euro Garages, one of the UK’s largest independent forecourt retailers, with the installation of a new gas-safety interlock system as part of the £12.3 million redevelopment of Rivington Services on the M61 near Bolton. The system was for the site’s Burger King outlet and meets BS 6173, which is required for new and refurbished commercial kitchens.
Waste wood that would otherwise be destined for landfill will power a CHP energy centre in Plymouth to generate about 26 GWh of electricity a year and about 10 GWh of heat. It will burn 40 000 t of waste wood a year. The plant will also produce over 1800 t of carbon a year, which can be used for applications such as gas cleaning, water filtration and filters for cooking hoods. The plant will reduce CO2 emissions by some 16 500 t to a year compared to grid supply.
