Case Study: Changi Prison Complex, Singapore

Changi Prison

Changi Prison was constructed by the British administration of the Straits Settlements as a civilian prison, in 1936. In 2000, the prison was demolished and the Redevelopment of Changi Prison Complex (CPC) project began.

The project encompasses the construction of 4 clusters of institutions, support facilities and Prison HQ, which will be implemented in phases. Each Cluster comprises 5 institutions with a mixture of maximum-security institution, medium security institutions and low-medium security prisons.

With the inclusion of the existing Tanah Merah Prison and Changi Women’s Prison, the entire complex when completed will have the capacity to accommodate 23,000 inmates.

The main lighting requirements for the streets and fence area of the new cluster at Changi Prison included reduced maintenance, lighting control and energy saving capabilities.

Metrolight’s 250w SmartHID™ electronic ballast, together with Menolinx’s lighting control and monitoring system, was chosen to provide the complete solution.

The Result
The three main requirements for Changi Prison’s lighting system included:

• Energy efficiency

- Achieved 44% energy savings
- Lamps are programmed to operate with 40% dimming as the default setting. In case of an event, such as fence tampering, lamps are programmed to increase to full power.

• Reduced maintenance costs

- Reduction in maintenance costs estimated at approximately 50% mainly due to double lamp life.
- Improved quality of light.

• Full control and dimming capabilities

- One central monitoring station.
- Central lighting management - LEMS (Lighting Energy Management Software) - from Menolinx
- Grouping - group lamps into areas for group control
- Automatic lighting control with photocells, cameras, sensors and motion detectors
- Two way communication: send commands and receive ballast parameters and lamp information including end of life alerts (decrease maintenance costs), lamp failure alerts, event alerts and energy consumption
- Communication: Ethernet
- Automatic scheduling

I think that everything posted was actually very logical.

But, what about this? suppose you added a little content? I am not saying your content isn't solid, but what if you added a title to maybe grab folk's attention? I mean Case Study: Changi Prison Complex, Singapore | Technilux Lighting is kinda vanilla. You should glance at Yahoo's home page and see how they create news headlines to grab people to open the links. You might add a video or a related pic or two to grab people interested about what you've written. Just my opinion, it would make your blog a little livelier.

He has truly giving us a lot Mr Tim Burton and I only hope he will give us more especially in the dark animation genre and try avoid the over the top 3D rubbish splattering our screens now. This is absolutely false as the movie makers are making money by letting you download and watch the movie for a specific cost. In the world of entertainment, gaining access to your favorite movies is not a big deal.
