Design No. 1 Air Cooled Water System

Intelligent Free Cooling

• An ambient temperature of 13°C or less will implement free cooling. The water is directed to the free cooling flow header and a number of tappings from this flow header distribute return water through the free cooling coils. The return water subsequently cooled by low temperature ambient air, is then fed to the free cooling return header and then directed to the evaporator inlet. This reduces compressor usage when the conditions permit

IBM Data Centre IBM Campus, Mulhuddart, Dublin 15

The IBM data centre is an 855m² unit built within an existing production area on the IBM campus in Mulhudart Dublin. The unit is fed from the dual redundant 110kV campus power feeds from the grid. There is full A&B dual power distribution throughout data suite. The UPS and backup generators throughout are n+1 resilient, the chillers are n+2. The down flow units utilise EC Plug Fan Technology delivering significant energy savings. There is dual redundant critical alarm monitoring of the major components within the unit. The unit is 2 hour fire rated and is equipped with wet cycle sprinkler protection. The unit benefits from the strong connectivity of the IBM campus

The unit went live in autumn 2008

Interxion Dub 2 Data Centre Parkwest Business Campus, Dublin 12

Ethos Engineering recently completed phases 1, 2 & 3 of Interxion's Data Centre facility in Parkwest in February 2010, September 2010 and January 2011 respectively. The data-centre is Interxion's 2nd instalment in Ireland and was was officially opened by Eamon Ryan TD, the then Minister for Communications, Energy & Natural Resources in April 2010 on behalf of the Irish Government. The Interxion Dub2 facility is a 2000m² of processing space which has been maximised by placing the incoming utilities, switchrooms, plantrooms and generators external to the building. The mechanical & Electrical systems have been designed to allow the roll out of the facility in a phased manner without any disruption to installed services. The mechanical and electrical systems were designed to maximise energy efficiency and the overall PUE for the facility. The facility offers redundant 4MVA grid connection, 2N UPS power and N+1 intelligent free cooling, as well as advanced alarm and monitoring systems. Ethos Engineering is an integral part of the design build team which has taken this project from concept design, through to detailed design, construction, commissioning and integrated system testing. Phases 4 & 5 are currently underway and will be completed later this year.

Project Examples

Dataplex Data Centre Ballycoolin, Dublin15 Ireland Ethos Engineering were engaged by Dataplex as part of the Design Tem for the construction of a new data centre at Ballycoolin Dublin 15. The facility when complete will consist of10,000m² of processing space which has been maximised by placing the generators external to the building. The key features of the project are; • Tier III design and N+1 redundancy • 14MW on site power supply • External generator compounds • Highly efficient air design • Presence for all main fibres and international carriers. The mechanical and electrical systems have been designed to maximise energy efficiency and the overall PUE for the facility. The target PUE for the facility is 1.2 The facility offers redundant 8MVA grid connection, 2N UPS power as well as advanced alarm and monitoring systems. The data-halls will be cooled by free cooling air handling equipment located in the mezzanine level plantroom above the MV & LV Switchrooms. The system design utilises fresh air free cooling in order to cool the data-hall air via an air to air heat exchanger. During high external ambient temperatures, the system will be assisted by an evaporative cooling array. Ethos Engineering has been part of the design team which has taken this project from concept design, through to detailed design and are currently at early construction stage. Ethos will also be responsible for the full IST of the M&E systems

Project Examples

IBM POD 2 Data Centre Commissioning Management IBM Campus, Mulhuddart, Dublin 15, Ireland

• IBM undertook the second of their Data centres in between July 2010 and April 2011.

• Ethos Engineering was employed as a direct client appointment to

programme, manage, control and witness the entire commissioning and Integrated Systems Testing of the new facility

• The process involved the writing and checking of all documentation

necessary for the successful implementation of the commissioning. It involved an intimate knowledge of the process and the functionality of the building and its consequential effects on both POD1 and the building 5 infrastructure.

• The Data Centre was successfully delivered fully tested and signed off

on programme to allow IBM roll the facility out to their clients

Interxion Dub 2.5 Data Centre Parkwest Business Campus, Dublin 12 Ireland

Ethos Engineering were retained by Interxion as part of the Design & Build team to construction their latest extension to their Dub 2 facility. The mechanical and electrical system design which was part of Dub 2, were designed to allow the roll of the facility in a phased manner without any disruption to installed services. The mechanical and electrical systems have been designed to maximise energy efficiency and the overall PUE for the facility. The facility offers redundant 4MVA grid connection, 2N UPS power and N+1 intelligent free cooling as well as advanced alarm and monitoring systems. Ethos Engineering is an integral part of the design and build team which has taken this project from concept design, through to detailed design and are currently at construction stage. Ethos will also be responsible for the full IST of the M&E systems

Project Examples

Telecity Data Centre – KCP Dublin Ethos Engineering were engaged as part of a Design Build team to provide electrical, mechanical and commissioning advisor services for the works to increase electrical capacity and resilience to Telecity’s KCP site. The project involved the installation of a new unit substation and critical switchboard along with 2 No 550kVA UPS units. The works were executed in a live data centre and involved the transfer of loads from the existing substations to the new substation. Existing mechanical plant was provided with secondary resilient supplies as part of the works to improve the overall resilience of the data centre. The works also involved the replacement of existing chillers with tie ins to the existing chilled water network. Additional cooling was provided to the existing switchroom to accommodate the increase in cooling load. Upgrade to the exiting BMS and energy management platform are formed part of the scope of works. Ethos Engineering were also responsible for writing and supervising the Integrated Systems Test (IST) and will manage the entire commissioning process.

Project Examples

Telecity Data Centre – NWBP Dublin Ethos Engineering have been engaged as part of a Design Build team to provide electrical and mechanical consulting services for the works to increase electrical capacity and resilience to Telecity’s NWBP site. The project involves the installation of Diesel Rotary UPS, back up generators, hybrid cooling towers, water cooled chillers, complete chilled water system changeover in live data centre, site BMS upgrade, 3 no. new data halls and new mechanical and electrical dual resilient distribution.

Project Examples

Ethos Engineering were appointed as the Mechanical and Electrical consulting engineers for the Paypal project in January 2012. The project consisted of high technical office space development within the existing structure and a mission critical disaster recovery (DR) facility. The design programme was extremely aggressive to meet the overall construction programme. Ethos Engineering achieved every design target date set by the client. The project also included full IST commissioning and testing for the mission critical DR facility.

The key features of the M&E system for the DR facility were as follows; • Free cooling chillers • Concurrently maintainable chilled water distribution • High density in rack coolers with hot aisle containment system • Differential pressure control • RH control • Fire suppression system with back up reserve • 2 No. cast resin close coupled transformers • 4 No. diesel containerised generators (N +1 resilience for the Data Centre) • Modular plug and play UPS system • Full IST commissioning • Full controlled gas suppression discharge testing and monitoring
