E7 Building Services

E7 Building Services (part of the Jarvis group of companies) were awarded the role of sub-contractor by Key Partnership Homes, to provide the necessary electrical systems for a complex of 97 apartments that were being built on behalf of Paradigm Housing Association.

The Challenge

Fitting all the fire alarms for the bin stores and plant rooms as well as all the electro-magnets for the fire doors within the communal areas across the two blocks. The intercoms for all 97 apartments and door entry system were also part of the project and these were a little more complex as there were 9 entrances to be connected to the intercom system. We needed to provide each door the required independent unlocking, which could have posed an issue for some, but not for the experienced Silver Group team.

However, the bigger challenge was with the smoke ventilation system. Due to current building regulations in regard to fire safety, it is necessary to have suitable systems to vent smoke out of the building in the event of a fire. According to Home Office figures, smoke accounts for almost 80% of all fire related deaths in the UK. These new systems require detailed specialist knowledge in ensuring they are installed and operate correctly. For these buildings in particular, it was more complicated as there were multiple corridors and stairwells over the two blocks.

The Silver Group Difference

Having successfully worked closely with Jarvis and E7 Building Services on previous projects, Silver Group were the natural choice for the installation of fire alarms, intercom systems and automatic opening ventilation systems (AOVs)In fact, Silver Group are one of the only companies in the UK that specialise in smoke ventilation, fire safety and security systems and so therefore are able to provide a truly integrated solution.

A state-of-the-art stairwell and corridor ventilation system was installed which included window actuators, opening roof vents and OS2 Control system. In the event of a fire, the windows and vents open allowing smoke to exit the building and therefore, vastly improve occupants visibility and ventilation as well as significantly aiding the fire-fighters.

In addition, this particular ventilation system was also connected to thermostats to allow the windows to open during warmer weather to cool the communal areas, and with rain sensors placed on the roof, ensuring they are closed during precipitation.

Benefits of Automatic Opening Ventilation systems are:

  • Improved smoke ventilation
  • Improved cost efficiency
  • Improved energy efficiency
  • Improved natural ventilation
  • Stronger all-round fire safety and security system
  • Easier fire and rescue access

The Results

All intercoms, fire alarms, door magnets and AOV systems have been installed, tested by Silver Group, and are fully operational to the exact requirements of E7 Building Services and Key Partnership Homes. The completed buildings themselves have now been handed over to Paradigm Housing Association, creating new homes for many!
