Siemens makes Dutch gyms safer and power-saving through its access control systems
 Access control effectively monitors and restricts the movements of staff and visiting personnel and provides valuable management information
 Seventy unmanned gymnasiums in the city of Rotterdam are being provided access control systems from Siemens
Siemens Building Technologies security solutions team was able to successfully rise to the challenge when the City of Rotterdam was looking for an effective access control method for 70 unmanned gymnasiums. A bespoke security solution was designed which has not only improved the operational efficiency of the gyms, but has significantly reduced the consumption of lighting, heating and air conditioning by 20%.

The gymnasiums are clustered in city districts and are visited throughout the day and evening by tenants who hire out a specified time slot. The gyms are supervised by on site managers who, prior to the installation of the new access control system, were handing out keys to the tenants renting the facility.

This was less than ideal as managers found it difficult to cope with the large numbers of keys in circulation and they were reliant on the tenants to keep to their allocated time slot and turn off the lights when they left the building.

The managers would set timers to manage the heating, so that the hall was at the right temperature when the rental period commenced. This system was open to misuse as tenants could use the halls for longer than the time they were entitled to and often forget to turn off the lights, resulting in increased energy bills and loss of potential bookings revenue.

It was evident that a cost effective control system to manage the flow of tenants using the gyms and to monitor heating, lighting and air conditioning was needed. Managing director of Siemens Building Technologies security solutions, Dave Pickles, explains: "Access control effectively monitors and restricts the movements of staff and visiting personnel and provides valuable management information. Siemens systems control and restrict movement at doors, gates, barriers and turnstiles. They can link to fire and intruder alarms and monitor environmental sensors."

 Siemens card technology allows full interchangeability
 As soon as a tenant enters the gym, the access system activates the Siemens building automation system 
Dave continues: "Sites can be networked and managed centrally, saving money on the manned security function and data storage. Siemens card technology allows full interchangeability, so you can enter a range of card types into one system for freedom of choice and cost-savings. This method can be used across many sites without compromising security."

The new access control system defines who has access at the time allocated. Instead of a key, the tenant is now given a chip card containing data relating to their booking. The system can also register who was using the facility at any given time. As soon as a tenant enters the gym, the access system activates the building automation system controlling air conditioning, heating and light management. Ten minutes before the session comes to an end, the tenant is alerted by an audible signal. At the end of the rental time the lights in the gyms switch off automatically and heating is reduced to a lower level to save energy.

The same system controls the changing rooms, with the warm water automatically stopping after time allowance is up. The system registers the first and final rental sessions of the day and automatically selects the appropriate day or night levels of heating and lighting.

Each night the registered data from that day is automatically uploaded to each manager's GSM modem. Simple to access information is supplied daily, directly relevant to each gym and facilitates remote active management. All details are recorded including the times that cleaners or engineers have been at work. Text messages report immediately on technical faults, emergency incidents or doors that are left open.

Since the installation of the access control system there has been a reduction in CO2 emissions across the 70 sites and energy consumption has decreased by up to 20 per cent. The City of Rotterdam has also benefitted from a 10 per cent increase in income from the rented time slots as now gym users are unable to continue using the facilities once their time is up!
