Key Activities
Over the course of this semester we will develop a low energy data centre for a major computing company by:
Meeting twice weekly to discuss project and update team members on work done
Researching the site, climate and local resources available
Creating a concept design – an example of sustainable architecture with efficient technical sub-systems
Undertaking performance and cost appraisals for our concept
Generate a web site to convey our work
Project Management
Week 1-3
• Organise group• Begin research of data centre use, data centre design criteria and the local
area• Prepare for Week 3 crit
Week 3-4
• Decide which team members will take responsibility for each relevant technical sub-system
• Research web site design• Finalise sizing of data centre
Week 5-6
• Begin to generate web site• Consider and create sustainable design for technical sub-systems• Prepare for Week 6 crit
Week 7-8
• Undertake performance and cost appraisals for proposed design• Prepare for Week 9 crit
Week 9-10
• Finalise design of data centre
Week 11-12
• Finish web site design• Prepare for final crit
ResearchSite Assessment
Situated in the small village of Allandale , the site is located between two rail tracks with close proximity to the M8O motorway.
The site occupies an area of around 6O,OOOm2 and was previously used as Castlecary Brickworks until it closed in 198O.
Site is centrally located and therefore should make use of local materials available.

Excessive heat loss for part the year
Overheating for part of the year
ResearchClimate
Fairly constant levels of rainfall throughout the year
From SEPA flood maps – Medium chance of surface water flooding associated with heavy downpours of rain
Possibility to utilise rainwater in the building design

Yearly total of 1256 hours
High levels during the summer and significantly lower during the winter
Large site so PV may be an option

Wind speed
25.2 m/s (fundamental basic wind speed from Tedds)
Prevailing winds from the South West
Wind speed is reasonable consistent throughout the year
Atmospheric Pollution
Low – Moderate levels of pollution
Site may be affected by pollutants from the motorway and industry in nearby towns
May cause some building materials to deteriorate

Initial IdeasConsiderations
We will appraise our options and make final decisions regarding our design by considering the following:
Energy consumption and the impact of demand reduction measures
The role of embedded new and renewable energy supply technologies
The environmental performance of the design
The environmental impacts of the embodied and operational energy
Initial IdeasBuilding design
A data centre has strict operating conditions:
Running temperature should be between 40% and 60%
Light levels in the equipment rooms and office spaces should be between 300 and 500 lux
Room acoustics should be considered to maximise the occupants comfort
Initial IdeasTechnical sub-systems
Our preliminary ideas for the energy systems in our data centre are as follows:
Initial IdeasTechnical sub-systems
Cooling System
Factors to consider: Ambient temperature v ideal temperature inside data centre Relative humidity – prevent moisture forming Prevent dust from entering cooling system/IT equipment Cost Environmentally friendly Energy efficiency Potential option to expand
Initial IdeasTechnical sub-systems
Cooling specifications to meet:
Building needs to be continuously cooled to prevent IT equipment overheating and failing
Needs to be at a suitable temperature for both computing equipment and staff
Cooling demands should be minimised and passive cooling should be used where possible
High priority Low priority
Initial IdeasTechnical sub-systems
Cooling Options
Initial IdeasRenewables
Energy Supply
Energy specifications to meet:
Should employ demand management Minimise reliance on grid electricity Maximise the quantity of energy supplied from
local sources Showcase for multiple renewable energy
technologies;
High priority
Low priority
Initial IdeasRenewables
Could use energy generated from Todhill wind farm roughly 6.5 miles away and has an annual energy production of 26.29 GWh
Initial IdeasRenewables
CHP – can control energy costs while improving reliability of power for data centres
Could provide air conditioning as well as electricity for IT equipment
Would reduce emissions, including CO2, SO2 and NOX.
Solar PV – large site area so solar panels could be used on excess land
Would only provide a small contribution in winter months Relatively expensive initial costs For our project we will source local climate data and then
assess supply/demand match to determine feasibility
Next steps
Our plan for the next 3 weeks is to:
Decide which team members will take responsibility for each relevant technical sub-system
Research web site design and begin to generate our site
Finalise sizing of data centre
Consider and create sustainable design for the energy systems
Prepare for the Week 6 crit
