Data Centres in Smart Cities
Smart cities can reduce:
• Energy use by 30%
• Lighting by 30%
• Building operating costs by 20%
• Water use by 15%
• Cut carbon emissions, improve air quality

RenewIT overall objective
• To develop a simulation tool to evaluate the
energy performance of different technical
solutions integrating Renewable Energy in
Data Centres

Data Centres in an energy-efficient
and environmentally friendly Internet
“Development of system level
technologies and associated
services that improve the energy
and environmental performance of
urban data centers”
Data Centres in an energy-efficient
and environmentally friendly Internet
Builds on earlier projects
Cluster objectives
•Energy monitoring and optimisation
•Renewable energy sources for Data Centres in
cities
•Heat reuse at urban neighbourhood level
•Integration of data centers with smart grid
schemes
•Standardization
•Validation in real settings

RenewIT Tool
Web-based planning tool to help data
centre owners, operators and design
organizations understand the economic,
energy and sustainability costs of
building a facility which used high
proportion of renewables
Energy concepts
Energy flows
Energy efficiency
Optimise the scheduling and placement of VMs
Advanced modelling
• Quantify benefits of
possible solutions
• Model in TRNSYS
• Meta-models
incorporated in the
RenewIT tool
Validation in real Data Centres

Metrics and KPIs
“The projects DOLFIN, GENIC, RenewIT,
DC4Cities, GEYSER, GreenDataNet, All4Green
and CoolEmAll will cooperate in order to share
experiences on topics common in all these
projects.
The first common topic identified is metrics to
measure Data Centre energy efficiency.”
