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

6

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

www.renewit-project.eu

“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

Data Centres in an energy-efficient and environmentally friendly Internet

Builds on earlier projects

•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

Cluster objectives

RenewIT overview

10

RenewIT ToolWeb-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 efficiencyOptimise the scheduling and placement of VMs

Advanced modelling

• Quantify benefits of possible solutions

• Model in TRNSYS• Meta-models

incorporated in the RenewIT tool

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.”

Metrics to capture ...• Energy/Power Consumption metrics

1. PUE – Power Usage Effectiveness2. CER – Cooling Effectiveness Ratio3. EE – Energy Effectiveness for HVAC cooling mode in a season

• Data Centre Flexibility1. APC – Adaptability Power Curve2. APCren – APC at Renewable Energies3. DCA – DC Adapt4. FER – Flexible Energy Rate5. MER – Managed Energy Rate6. MFER – Managed Flexible Energy Rate

Metrics to capture ...• DC Flexibility: Energy being federated

1. FEW – Federated Energy Weight2. Federated COP3. Federated RES

• Renewables Integration: Energy produced locally and renewables usage1. RenPercent2. RenEPPercent3. RenThermPercent4. RenEPThermPercent5. TotalEPPercent6. REF – Renewable Energies Factor (local RES)7. Grid interaction indicators

Metrics to capture ...• Energy Recovered: Heat Recovered

1. ReusePercent2. ERE – Energy Reuse Effectiveness

• Primary energy savings and CO2 avoided emissions1. PE savings – Primary energy savings2. CO2 savings – CO2 avoided emissions

• Economic savings in energy expenses1. EES – Energy Expenses Savings

• Capacity planning & management1. ITEE – IT Equipment Energy Efficiency
