Presentation Transcript

  1. Presentation of Design Proposal Data ONE, European Operations Centre, St. Petersburg, Russia

  2. Introduction • Internal Temperature Setpoints – CIBSE Guide A • External Temperatures – ASHRAE handbook • Finalised heating, cooling and electrical load

  3. Building Sustainability • Data Centre Design • Alternative Energy Sources • Solar, Biomass, Wind, Heat Pump • Combined Heat and Power • Electric Vehicles • Smart Metering • Triple Glazing • Lighting Design

  4. Building Safety and Security Fire Safety Building Security Building Regulations and Compliance

  5. Ventilation • Importance of Ventilation • Ventilation types considered: • Natural • Mechanical • Mixed Mode • Only occupied rooms were ventilated

  6. Air Conditioning Plant • Air conditioning plant considered: • Local • Centralised • Partially Centralised • Centralised systems considered: • Variable Air Volume • Displacement Ventilation • Constant Volume • Reasons for selection of VAV

  7. Diffusers • Location • Suspended Ceiling • Selection Method • Room Dimensions • Comfort Criteria • Flow rate • Swirl Diffusers • Uniform air flow

  8. Ducts and Fans • Ducts sized based on flow rate • Fans sized using index circuit • Equal Pressure Drop method • Kitchen and Basement ventilation • Separate extract system • Insulation around ducts

  9. CHP • Sokratherm GG140 Compact CHP Unit • Running from October – April each year • Electrical Savings Versus Grid: €38,500 • Heating Savings Versus a Boiler: €23,150 • Payback Period: 5.44 years

  10. Heating Control

  11. Cooling Control Cooling control similar to heating control, except with chillers instead of the heating supply. Highest cooling demand shall be catered for. VAV will reduce air supply. Trace Heating. Energy use is kept to a minimum by use of EC pumps and fans

  12. Transformer Sizing • Max Electrical Load: 650kVA • Transformer Sized: 800kVA • 3 Phase Delta/Star Connection • Siemens GEAFOL: Cast-Resin Insulation • Self Extinguishing • Low Maintenance

  13. Psychrometric Analysis • Summer Design: • Worst Case Cooling • Design for Coolest Room • Ambient Temperature: 34oC • Winter Design: • Worst Case Heating • Design for Warmest Room • Ambient Temperature: -34oC

  14. Free Cooling Kyoto Cooling Air Handler Capital Cost: €153000 Cooling Power of: 90kW Full Load Power Requirement: 45kW Unfeasible Option

  15. Datacentre System Hot Aisle: Cold Aisle Recirculated Air Only Constant Volume Maximum 2 Occupants Maintains Setpoint During Possibility of Server Fault

  16. Lighting & Safety Strategy • Everyday Lighting • Emergency Lighting • Escape Routes • Fire Detection & Suppression System

  17. Everyday Lighting • Recessed • T5 Efficiency • DIALux • Control • Motion Sensors • Photo Sensors

  18. Emergency Lights & Escape Route • Ceiling Mounted • DIALux • Escape Route • Emergency Lights • Requirements • 1 lux on route • 0.5 at Edges

  19. Heat Detection & Fire Suppression • Heat Detectors • 12m Apart • 5m from Walls • Fire Suppression • Water Mist System • Foam System in Basement (TGD F) • Break Glass Units • Smoke Control System

  20. Building Regulations Check • Full Compliance with the Irish Building Regulations. • Sound • All air diffusers selected to meet noise limits • Sound attenuators provided for: • Call Centres • Conference Room • Meeting Room • Training Room

  21. Building Regulations Check • Ventilation • Sufficient fresh air provided for all occupants • Special attention given to toilets, kitchen & canteen. • Filtration to remove dust from supply air • Dedicated extraction system for basement • Conservation of Energy • Insulated floors, external walls & internal partitions • BMS setup to minimise energy consumption

  22. Building Regulations Check • Fire Safety • 2 means of escape for all occupants • One fire-rated lift for evacuation of disabled occupants • 5 fire compartments (each floor plus basement) • Two extraction fans in basement plus foam suppression system • External hard standings required for fire services

  23. Conclusions Most efficient ventilation system to be installed All internal conditions in accordance with guidelines CHP chosen as the most economical power source Comfortable & efficient lighting Complies with all Building Regulations.
