1. Data Centre Design

2. PROJECT BRIEF Develop a low energy data centre for a major computing company. Building is to be a prime example of sustainable, low energy architecture. Expected to be an exemplar for future data centres.

3. SITE Site is an old derelict industrial site near the village of Allandale. Approximate size of site is 200m x 300m. Already a fairly flat and solid surface to build on. Large open site, not a lot of shelter except surrounding trees. Close to the motorway and enclosed by two railway lines.

4. DATA CENTRE REQUIREMENTS Data centres require a number of things in order to function, these include: Space Cooling/Ventilation system Power Supply Detection Systems Security

5. SPACE Needed for servers, cables and ventilation. Sufficient enough for up to 50 IT, security and maintenance staff Includes offices, canteens and toilets etc. Power storage. COOLING AND VENTILATION Due to large heat gains from the IT equipment, building requires cooling/ventilation system. Building will need to be kept at right temperature and humidity in order for smooth operation and performance of systems.

6. POWER SUPPLY Total electrical power demand of 5MW Supply has to be smooth and uninterrupted. Utilise some sort of renewables and be cost effective. DETECTION SYSTEM Advanced fire and water detection systems. SECURITY Physical, video cameras and guards

7. LOCAL RESOURCES “where possible the building should source local building materials” Forth and Clyde canal. Cowden Hill Quarry Nearby Farms Local Wood Supplier Steel Works

8. The Forth and Clyde Canal - Water Supply - Water Cooling - There is no flow Cowden Hill Quarry - Specialises in Aggregates - Concrete and stone supply - Foundation Work

9. Local Farms - “Feedstock” - Anaerobic Digestion - Energy Supply - Expensive Local Steelworks and Woods - Woodchip - Biomass - Steel Structure

10. Climate Temperature Yearly Max Average – 12.9 °C Yearly Min Average – 5.4 °C Daylight Hours Winter – Around 7 Hours per day Summer – Around 17 Hours per day Yearly total – 1228.6 hours

11. Wind Average wind speed – 24 km/h Natural Ventilation Wind Turbine Precipitation Average – 938mm Water collection Rainwater harvesting (Grey Water)

12. Our Concept

13. Building size 1KW per m² for 5MW requirement 5000 m² floor space for computer equipment Additional space required for staff Space for expansion

14. Building layout Consisting of data halls, office space and staff facilities 1 storey building to maximise roof space for PV panels The building should be south facing to receive maximum daylight exposure.

15. Materials Steel framed building with steel sourced from local steel works Use of glass to provide natural lighting for staff Foundation materials sourced from local quarries

16. Brief States – Maximum use of natural Light Tubular Daylighting System (TDS) Size range from 250mm- 900mm 900mm tubing provides light for 95m 2, X required. Lighting

17. Power Demand 5MW for IT equipment Typical office space peak demand12W/m 2 = X W for office Energy saved with TDS, heat recovery from IT equipment Extra Energy expelled with additional cooling requirements

18. Wind Turbines 10m hub height wind turbines Average wind speed = 24Km/h = 6.6 m/s Annual Energy = 0.3 x 2.09 x D x W Larger turbine (1.5MW) can be used if planning permission allows it (building height <10m)

19. Existing & possible solutions Ventilation & cooling system Natural ventilation : use the wind Mechanical ventilation : electrical pump Hybrid ventilation : use both natural and mechanical systems

20. Ventilation & cooling system Special requirement for the data room : Temperature : -maintain a temperature between 18 and 27 degrees Never exceed 45 °C Humidity : maintain humidity between 40 and 60%
