2 Learning Objectives By the end of this module you should be able to: List the four steps in the ICT environment required to provide a high quality service while minimising energy and material consumption and toxic dispersion Breakdown the assessment into energy and materials consumption Classify and separate the consolidation step into servers/cloud, desktop computers and thin clients, imaging equipment Consider the importance of supplies inventory management in the chain of energy conservation Discuss innovative factors to reduce energy and materials consumption Recognise management as a key final step in the overall effort to minimise energy and material consumption and toxic dispersion.

3 Introduction End-user ICT equipment Consumes a considerable quantity of energy and materials, and introduces toxic substances into the ecosphere. Distributed across floors in buildings, campuses, cities, countries and in the case of multi-nationals even globally. Effective management necessary or Service degradation Energy and material resources consumed.

4 Introduction ICT environment to provide a high quality service while minimising consumption and toxic dispersion: Assess Consolidate Innovate Manage.

5 Assess - Power consumption Distribution Line Carrier (DLC) System khz Data rate ~ 576 kbit/s Device Language Message specification (DLMS) COmpanion Specification for Energy Metering (COSEM) DLMS/COSEM Smartmeter Data concentrator

6 Assess - Power consumption Centralised monitoring and control of power consumption and thermal output. HP ProLiant servers Insight Power Manager (IPM). Dell PowerEdge OpenManage Power Center. Dell PowerEdge Servers HP ProLiant Servers

7 Assess - ICT management & Monitoring tools Nagios Cacti Industry standard enterprise-grade ICT infrastructure monitoring tool. Network graphing solution. SNMP

8 Assess - Desktop energy budget calculation Electricity is charged at UGX / KWh Assumptions: 30% left powered on: Business day = 8 hours The new electricity bill is: Business week = 5 days 167,055,525 UGX Business year = 50 weeks An unnecessary increase of 82% Number of computers in business = 500 Item Formula Value Desktop computer + monitor 100 W (0.1 kw) 0.1 kw Hours per week 9 hrs x 5 days 45 hours Power consumed weekly 45 hrs x 0.1 kw 4.5 kwh Power consumption in year 4.5 kwh x 50 wks 225 kwh Total power consumption in year 225 kwh x ,500 kwh Power consumption cost in year 112,500 kwh x UGX / KWh 91,788,750 UGX

9 Assess - Consumable A product is one that gets used up, that is, it can spoil, or has a life. Something that consumers buy recurrently because they are used up or discarded.

10 Assess - Non-consumable An item that can be used without altering its substance except for natural deterioration over time. Capital goods.

11 Assess - Consumption Simple method Assess materials consumption by: Counting the number of non-consumable items Measuring the consumption rate of consumable items over time Compare these numbers to the number of users and services over time.

12 Assess - Consumption Detailed method Input/Output Analysis (IOA). Pre-calculation of a set of input data related to the operation of equipment Estimation of the resource input on the basis of IOA using macro analysis in the form of a physical inputoutput table i.e. annual consumption of electricity, natural gas, petroleum, and paper. i.e. financial data such as annual investments, equipment purchases, or revenue. Post-calculation including a summation of the precalculated and estimated data and allocation of the summation to material groups.

13 Assess - Identify waste An assessment may reveal obvious unnecessary consumption of energy and materials, particularly: During high consumption period During peak consumption periods After business hours.

14 Consolidate - Servers Own server infrastructure Costs Hardware Power consumption Heating, Ventilation and Air Conditioning (HVAC). Local Data Centre Minimise the power consumption per unit Additionally power and transit security.

15 Consolidate Total Cost of Ownership License & Subscription. Installation and setup. Customisation & Integration. Other considerations Data migration, training, maintenance and support.

16 Consolidate - SBCTC A Desktop PC can use over 3 times more energy than a SBCTC. Virtualisation Thin clients Network Internet

17 Consolidate Imaging equipment Accumulation of ancillary equipment Printers, copiers and scanners. Communal imaging docks.

18 Consolidate Supplies inventory Over stocking spares inventory can prove costly Obsolescence, shelf life. Economic value of supplies inventory becomes one of the largest components of warehouse cash flow.

19 Innovate Energy Consumption Incorporate the latest innovations in sustainable design and technology into ICT equipment to further reduce costs and energy and materials consumption. ICT equipment Worldwide electricity consumption is at ICT electricity consumption 3% Communication networks 10% Personal computers 5% Data Centres 4% Need for energy-efficiency research across all these domains, rather than focusing on any single one.

20 Innovate Reduce energy consumption Select the appropriate ICT equipment Appropriate right-sized item not big is better approach They are often cheaper to purchase because they are lower capacity They operate near their design loads, which can make them up to twice as energy efficient as oversized equipment operating at low load They emit less heat and thus contribute less to cooling load They are generally smaller, lighter and safer to handle.

21 Innovate Reduce energy consumption Select ICT equipment with the right features like: Sleep and wake speed Computers Not all tasks require high performance computers with large monitors. Imaging equipment Standby mode is more likely to be used with fast sleep and wake speeds. Print speed, colour diversity, colour intensity, page count and ink melting point. Ink-jet printers consume about 90 percent less energy than laser printers. Combined function machines Combine the function of a printer, fax, scanner and photocopier consumes substantially less energy and requires less space.

22 Innovate PM Strategies PM benefits, including: Reduced heat production which leads to lower fan speeds and hence quieter and more efficient operation Increased battery life in mobile equipment. The spectrum of PM strategies: Simply turning off equipment after hours Setting equipment to: Consume minimal power when in use Turn off after a period of inactivity. A desktop computer with an 18 LCD monitor uses 2.5 times more energy when the PM is disabled, than when PM is in the energy saving setting. Scripts to safely hibernate computers.

23 Innovate PM Options Processors PM features that can dynamically adjust the voltage and clock speed Can reduce energy consumption and heat generation by up to 40%. System BIOS Dynamic energy consumption adjustment via sleep states: Standby (only processor halted) Suspend to RAM standby (only RAM operating, < 5 W power) Suspend to disk hibernation (only hard disk operating) Soft off state (almost off but can wake from external input, < 2 W power). Dynamic system cooling Control the internal thermal environment Control acoustic levels Throttling, reducing clock speed to reduce heat generation.

24 Innovate Low energy ICT equipment Processors Thermal Design Power (TDP) refers to the amount of power/heat a cooling system is expected to dissipate to prevent overheating (Watts).

25 Innovate Low energy ICT equipment Monitors LCD technology over CRT monitors. Power supplies Mainstream power supplies are typically 80% efficient Level VI standards and CoC Tier 1 and Tier 2. Storage memory HDD vs. SDD. Computers SBCTC, low processing power and few components 3 times more energy efficient than a desktop computer. Communication technologies Teleworking: Video conference systems Voice Over IP (VoIP) Distributed computing Large and complex calculations decomposed and performed in different geographical locations.

26 Innovate Materials consumption Reduce equipment mass and size. Use innovative and renewable or recycled materials. Replace potentially harmful materials. Eliminate materials of concern : Compliance: RoHS.

27 Innovate Eco-labels Identify low-energy, low-materials and low-toxicity ICT equipment US EPA Electronic Product Environmental Assessment Tool (EPEAT) EU Ecolabel National eco-labels.

28 Manage Manage & monitor ICT Continuously managing and monitoring for opportunities to: Replacing inefficient ICT equipment when cost effective Ensuring appropriate EoL processing of the replaced equipment Recycling spent print cartridges and paper Monitoring and reporting energy and material consumption Sustainable purchasing and procurement policies Scheduling non-critical, high-energy activities out of peak periods.

29 Manage Assess cost effectiveness Energy costs Alternative uses for the replaced equipment The impact on user productivity when running newer software Technical staff costs, including salary, infrastructure and transport.
