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

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.

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

Page 17: Lebd crit 1 (final version)

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

Page 18: Lebd crit 1 (final version)

Initial IdeasTechnical sub-systems

Our preliminary ideas for the energy systems in our data centre are as follows:

Page 19: Lebd crit 1 (final version)

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

Page 20: Lebd crit 1 (final version)

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

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

Page 23: Lebd crit 1 (final version)

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

Page 24: Lebd crit 1 (final version)

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

Page 25: Lebd crit 1 (final version)

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
