Project Background
The aim of the Schools Programme is to deliver new schools in rapidly developing areas either by replacing existing schools with new accommodation or providing new accommodation for schools that are an amalgamation of existing schools. The schools are to be delivered by way of Public Private Partnership (PPP) arrangements. The schools are planned to be delivered by way of two bundles (Schools PPP Bundle 4 and Schools PPP Bundle 5) procured under a single contract notice using the negotiated procedure.

Schools PPP Bundle 4 provides a total of 2,950 school places in four schools. Under the PPP model, the schools were designed, built, financed, and will be maintained under a 25 year service contract. The debt financing solution comprises AIB and KFW.

Fully Addressable Fire Alarm System
The addressable fire alarm system within this building has been installed and commissioned in accordance with IS3218:2009 Code of Practice for Fire Detection and Alarm Systems. This Windows Based System allows for full upload / download facilities, is fully networkable, has powerful processing and extensive panel and loop I/O capability and features user friendly controls and a clear, unambiguous screen. For a full system description please see Fire Alarm Section of this Safety File.

Emergency Lighting
The emergency lighting system within this building has been designed, installed and commissioned in accordance with IS3217:2008 Code of Practice for emergency lighting systems. In the event of a loss of power the full emergency lighting system is automatically activated and will remain activated for a period of up to 3 hours or until power is restored when it will automatically de-activate. For a full system description and data specifications please see Emergency Lighting Section in this Safety File.

Lighting System
The Lighting Distribution System has been installed by Burke Electrical Installations using an energy efficient High Frequency lighting system. High Frequency lighting has a silent operation, gives instant licker free light and has an automatic shutdown of failed lamps. For a full system description and data specifications please see the lighting section of this this Safety File.

Security System
The intruder alarm system at Comeragh College has been installed to detect intrusion. For full systems description and data specification sheets please see the relevant sections of this Safety File. All details relating to the CCTV System installed are contained within the CCTV section of this Safety File. Full usage guides, system descriptions and data specifications can be found in this Safety File.

Access Control Systems
This access control system has been installed to remotely permit or deny access to the school building. This system allows access to only those who are permitted to gain entry to the specific area. Please see the access controls section of this Safety File for a full system description, data sheets and user guides.

Data Communications System
The communications system within the school has been installed, tested and commissioned by CET as per the design requirements given. Details of the communications systems can be found this Safety File along with data specifications and test results.

Electrical Distribution Panelling
The distribution panels within the school has been built by a specialist manufacturer as per the design requirements given. The drawings giving dimensions and layouts, the distribution panel layouts and the specialist manufacturers testing is all included in this Safety File.

General Service Outlets
Click wiring accessories have been installed throughout this facility. For full data specifications please see the general services section of this Safety File.

Heating System
Zehnder ZBN radiant ceiling panels emit a large proportion of their heat by radiation. The remaining heat is transmitted through convection. The emission of the radiation is achieved by having heated water flow through the tubes. The entire system emits this heat into the room. The advantage of our system is in the direct action of heat on the  body without having to heat the air. The temperature we experience is a combination of radiant and air  temperature. Cooler air temperatures can be offset by increasing the radiant component to achieve  comfortable resultant temperatures. By using radiant panels to increase the surface temperatures of the room, the air temperature is normally reduced by 3 K and still achieves comfortable internal temperature conditions. This is the most energy efficient method of heating.

Cooling System
The cooling action works on the same physical principles as the  heating action, although now the heat is not emitted, but absorbed: The cold radiant ceiling panel  absorbs radiant heat from the  hotter surfaces. This constitutes approximately 60 % of the cooling  effect. The remaining 40 % is achieved by convection: The warm room air, which is less dense, rises and flows along the ceiling. It then transfers its heat energy by convection to the cooler radiant  ceiling panel. The cooled air which is now denser falls back  into the room. The perceived temperature in the room is actually lower than the air temperature due to the radiant cooling effect of the panel. Once again this is the most energy efficient method of providing cooling in comparison to other systems which rely on reducing the air temperature.
