Conclusions: Towards Greener Pasture? OUTLINE 1. The Impact of Buildings on the Environment and the role of ICT Energy and Carbon Footprint Buildings account for: 38% of all carbon dioxide (CO2) emissions 72% of electricity consumption 39% of primary energy use The IT industry generates 2% of world GhG emissions, 25% in commercial buildings Lighting generates 20% of the world GhG emissions, 11% in commercial buildings BUILDING AND GREEN ICT The built environment has a profound impact on our natural environment, economy, health, and productivity. Intelligent Building Infrastructure BUILDING AND GREEN ICT IT and Facility Networks Convergence BUILDING AND GREEN ICT Always On vs. Always Available Always On Presence-based Activation Scheduled and Behaviour-based Activation Personalised Building Resource Management Staying Secure! Requires an Integrated Solution including: Context- Aware Access Control Real Time Locating System (RTLS) Power Resource Management …cooperating over a converged Building Network BUILDING AND GREEN ICT Always Available 2. Energy Efficient Access Control Energy Efficient Access Control Architecture Building Access Control Real Time Locating System Data Source Abstraction Layer Data Source Manager IP Based Devices Sensor Abstraction Layer Mediators Sensors Non-IT Equipment ENERGY EFFICIENT ACCESS CONTROL Building Power Management System Energy Efficient Access Control Location Information is combined with Schedules and Behavioural Analysis, in order to further improve efficiency in Security Monitoring Power Management Systems interact with Access Control systems in order to provide: Secure and Personalised Building Resource Allocation and Management Dynamic allocation of resources according to context Quick view on the energy footprint of current security policies ENERGY EFFICIENT ACCESS CONTROL Access Control is supported with Real Time Locating System feedback, connecting User Access Profiles with Location Information 3. Research results on more efficient Real Time Locating Systems Real Time Locating Systems Technology Market Share Wi-Fi Active RFID Passive RFID 55% 13% 4% RFID/IR Infrared ZigBee Ultra-wideband <1% 12% 6% <1% Ultrasound 10% REAL TIME LOCATING SYSTEMS In a 2009 Market Study out of 122 organizations known for being progressive in their use of healthcare IT (HIT), only 35 of those organizations are doing anything in the way of real-time location, even fewer had deeply implemented a solution. A variety of technologies exist, each with pros and cons in terms of cost, accuracy and infrastructure requirements. Current Research for Indoor Localisation is working on improving efficiency, cutting down infrastructure costs Ultra-wideband 2D Typical Ubisense LOSSLES Technique Mean 1.23m 0.48m Median 0.44m 0.44m 67-th Percentile 0.56m 0.48m 95-th Percentile 3.95m 0.95m REAL TIME LOCATING SYSTEMS Evaluated at NCSR LocTrack Laboratory “+”: accuracy, robustness, “-”: high cost Significantly improved accuracy with LOSSLES technique: understanding the area of location and removing measurements from sensors w/o free LoS Ultrasound 4-Listener Cricket Bundle Horizont ally Positione d Best Vertical Orientati on Without Calibratio n With Calibratio n Mean accuracy 11.68m 10.81m 0.44m 0.30m 95th accuracy percentile 27.17m 40.17m 0.96m 0.82 REAL TIME LOCATING SYSTEMS 1 Listener only (Calibrated) EVA LUA TIO N RES ULTS : POSI TIO N TRA CKIN G (CRI CKET ) Evaluated at NCSR LocTrack Laboratory “+”: low intrusiveness of infrastructure, “-”: performance, ergonomics, usability Susceptible to Noise interference Improved accuracy with 4-listener cricket bundle, lacking in ergonomics and usability: ZigBee REAL TIME LOCATING SYSTEMS EVA LUA TIO N RES ULTS : POSI TIO N TRA CKIN G (CRI CKET ) Evaluated at NCSR LocTrack Laboratory “+”:cost effective, “-”: offline measurements (scene analysis – SA) are needed for higher accuracy Worked on techniques to improve accuracy w/o need for scene analysis (APIT) RFID REAL TIME LOCATING SYSTEMS RFID systems can use a combination of passive, active, or semi-active tags to meet varying tracking needs. RFID systems utilize proprietary hardware that limits interference or impact on existing wireless networks. RFID requires additional infrastructure costs. Active tags require battery maintenance and consequently, they cost more than passive tags. NCSR current research work focuses on reducing infrastructure costs and improving efficiency by: Reducing the number of RFID readers Make use of directional antennas controlled and activated selectively Support from Reasoning and Location Information Modelling Location Information Modelling REAL TIME LOCATING SYSTEMS The DITSEF Platform for Aftermath Crisis Management “Bubbles”: Sets of “HABBLE” nodes Self-organized network between HABBLE nodes Self-organized networks among Bubblesη “HABBLE” Nodes: GPS and UWB modules for Localization WiMAX and ZigBee modules for Communications Digital and innovative technologies for security and efficiency of first responders operation (DITSEF) Funded under 7th FWP (Seventh Framework Programme) HMFM indoor localisation of medication package on demand HMFM Home Services and Reasoning Server Wi-Fi Connectivity RFID Reader RFID Reader NFC Mobile Phone NFC Service Access Point Misplaced RFID-printed Medication Hear Me Feel Me - Compensating for eyesight with mobile technology AAL (call 1) 4. Conclusions: Towards Greener Pasture? When Business Profit meets Green Profit Business Objectives: Branches and HQ operates from 9:00 am –6:00 pm Control Laptops, PCs, Phones, APs Solution: Energy Management System on: IP phones, WLAN, PC, IP-connected HVAC, lighting, identity readers Business Value: $502,235 annual savings Equates to emissions from 194 homes, 499 acres of pine forest sequestration, or travel around equator of earth 1.43 times Business Value: $415,475 annual savings (assuming 0.10/kwh), 55.6% power savings Emission reduction of 2,197 metric tones, equates to 399 cars emissions TOWARDS GREENER PASTURE Business Objectives: Reduce power consumption of the clinic (200,000 sq. ft. facility) Control all IT and facility power usage Beware of the Hype TOWARDS GREENER PASTURE A lot of hype building around the green ICT movement Consolidate security without increasing risk – don’t jump on Green Security per se Security specialists are challenged to decide among many products which best meet the needs of the organization, applying them effectively …cutting down costs and carbon dioxide emissions in the process Conclusions – Towards Greener Pasture? TOWARDS GREENER PASTURE Internet of Things and convergence of ICT with our surroundings is getting us there Over the converged Building Network, Access Control empowered by Indoor Localisation intelligence, can cooperate with Power Management systems to produce a more effective integrated system Indoor Localisation research is working on increasing accuracy while dropping down costs, esp. in terms of infrastructure – suiting the Green goals Success stories already out there and motivate the Green ICT movement: Companies build upon the “save Trees and a bit of the World” image …while saving a good amount of money for themselves too!
