Carbon Footprint The energy required to run the IT system is 90-95% less than conventional systems and generates very little heat. Less Heat means lower Air Conditioning costs and more comfortable offices and IT suites Reducing power consumption reduces Greenhouse gas emissions like CO 2

Cost Reduction Benefits Reduced capital cost ( up to 50%) Reduced energy consumption (up to 100%) Reduced IT maintenance (up to 80%) Future proof (easy to upgrade to Windows 8) Better use of computer network bandwidth Utilise rooms previously not used as IT suites – Don’t have to add lots of extra 13Amp sockets and network points. – Increase the density of IT stations. Reduced Power Backup Solution requirements (UPS)

Benefits Reduce the environmental impacts – Lower energy demands means less CO 2 produced (learn more)learn more – Longer life devices and fewer computers used means less waste entering landfill sites (95% reduction) – Less heat means less air-conditioning and fewer system failures Other benefits – Takes up less space so more seats per room (learn more)learn more – Solid state technology, less moving parts, less to go wrong. – Built in redundancy in the event of hardware failure and also provision for maintenance during office hours and remote administration

Benefits Loans are available from Siemens Finance to introduce energy efficient systems (learn more)learn more Reduced infrastructure costs such as Backup Generators and Uninterruptable Power Supplies. – The Green IT servers have an integrated UPS which allows the server to continue running for between 3 and 9 hours (depending upon load) once the external power supply is removed. – When used in conjunction with the GreenIT power bank, your GreenIT solution can run off grid for several days without being topped up from Solar or mains energy. – Therefore smaller and cheaper Diesel generators and UPS solutions are required within your organisation or they can be removed altogether.

Ultra low power servers & PCs We provide a range of servers and PCs that are designed to be powered by solar cells or other renewable DC energy sources. All of the performance but without the waste found with conventional computers which have to convert AC energy to DC energy. The the only computers available with a 4* energy rating.

Back to the future! Thin Clients explained In the 1960s, 70s and early 80s computers were large and expensive, so they were centralised and accessed via “Dumb Terminals” or “Thin Clients” – All processing and calculations were done by the central computer (server) – The Dumb Terminal simply allowed an operator to enter a command and forward the associated key presses to the computer down the corridor or in another city via a telephone line. – The centralised computer would calculate the answer and send a response back to the “Thin Client” to present the results on the screen. Thin Clients are becoming popular again because they can provide a low cost, high performance, secure computing experience using relatively modest servers.

Typical Desktop IT Solution 1000s of PCs rated between 110Watts - 300Watts Each PC wastes power converting the 240Volts AC down to 12v DC, spinning hard disks, cooling power supplies and CPUs. A relatively small amount of power is used to generate presentations, documents, spread sheets and to run analyses. The average PC has sufficient processing power to support the activities of several users simultaneously. Network drives/File Servers

Alternative Desktop Solution Network drives/File Servers Desktop Server An energy efficient desktop virtualisation server is introduced to the network. All computer base stations are removed and replaced with a thin client or Network monitor. It has an Ethernet port, USB ports for mouse, keyboard and memory stick to allow the user to communicate with the server and maintain a computing session.

Alternative Desktop Solution Desktop Server The Desktop server provides each person with a virtual computing session. All processing is done on the server, not the Network Monitors. Very little energy is wasted in the form of heat by the monitors and servers. The monitor simply presents the results of what is happening on the server and processes the mouse activities and key strokes. Network drives/File Servers

Thin client solution for multi seat installations (offices, schools…. Sustainable Technologies solution is more responsive, reduces desk clutter, and removes the localised noise and heat common in office environments. Scalable - servers available to replace 5, 10, 25, 50 or 100 PCs. Provides a more resilient solution – if a server fails, all the clients are passed onto other servers and the load is shared. Replacing a failed client takes less than 2 minutes from taking it out of the box to plugging it into the network instead of several hours to depoly a new PC. More suitable than conventional IT solution for Schools, Offices, Governments, Hospitals and Corporate environments which require roaming profiles for their users and save data centrally or in “the cloud”.

Suitable Thin Client Environments Office and teaching environments – MS Office applications, Outlook, PowerPoint, Excel, Word, Visio – Training Rooms (teacher can communicate/control remote desktops) – Meeting Rooms (attach to smart boards & projectors) – Language Labs – Some CAD Systems – Photo Editing – Internet Access – Citrix access, X-term access to Unix servers – Software development – Data Entry – Call Centres – System Administration and Remote Access Applications – Receptions – Support and help lines AutoDesk supports their modelling suite AutoCAD on Thin Clients!!!!

Unsuitable Thin Client Environments Very Large 3D CAD modelling environments as used in the Aerospace industry such as CATIA. Video Editing These “unsuitable” applications typically can run on the Thin Clients, however a 25 user server which can support 25 MS Office and Browsing sessions may only support 4-10 video editing or 3D CAD sessions. The GreenIT PCs are very similar to the Servers - very powerful but don’t consume much energy. These machines can be configured as standalone Video Editing and 3D CAD machines.

Power and CO2 facts Conventional Solution – Desktop PCs are becoming more energy efficent but they will never match the efficiency of a MakeITGreen Server whilst it is running from mains power. – A conventional desktop PC consumes between 100 and 400 Watts (0.1kW to 0.4kW) – An optimistic estimate is an average of 0.2kW – 8hrs x 0.2 kW = 1.6kWhrs (Assume more as many PCs in Schools are left running 24/7 because they take so long to restart each morning) – 1.6kWhrs x 250 days = 400kWhrs – 1kW = £0.12 therefore £48 per year (Typically the reality is closer to £100) – 1kW = 0.77Kg therefore 308Kg of CO2 per year per computer* – 100 Desktop PCs = 40,000 kWhrs = £4800/year = 30.8 Tons/year CO2 EPT Server and Network monitor solution – 100 Thin Client Monitors = 100 x 11 Watts x 8hrs (per day) x 250 days (per year) = 2200kWhrs – 2 Servers = 2 x 40 Watts x 8hrs x 250 = 160kWhrs – Total = 2360 kWhrs Percentage of energy costs 2,360/40,000 = 6% This is an optimistic estimate and bear in mind that the 2360kWhrs used to run the Green IT solution could have been supplied from a small Solar Cell array directly without any inverter so 0 tons of CO2 is possible and viable. *

Microsoft Multipoint Server Multi-Point Server 2011 is a server based operating system from Microsoft based upon Server It is optimised to provide Windows 7 Desktop Virtualisation. – It allows the resources of a single computer to be shared by many users simultaneously which typically connect to the server via Thin Clients. Most computers have more power than a single user requires, therefore MPS allows the resources to be better utilised. Also centralising your desktop solution means that upgrades from Windows 7 to Windows 8 only involve upgrading the Server operating system – not the 100s of client computers.
