Understanding Hospital/ Healthcare Facilities
Schneider Electric – Chandrashekar TV
5
Hospital/Healthcare Facility Applications Complex, diverse and sophisticated buildings Critical environments: Operating Rooms, Intensive Care Units, neonatal wards Isolation rooms / pressurization controls Lab, drug and tissue storage facilities Data Centers
Integrated BMS adds tremendous value Eliminates component redundancy – one network Simplifies operation and control of complex systems Substantially reduces capital procurement and operational expenses Enhances security Schneider Electric – Chandrashekar TV
6
Hospital/Healthcare Facility Controls Needs Patient and staff comfort and efficiency Critical environments - precise temperature, humidity, IAQ and pressure regimens Operating Rooms – very fast response Isolation Rooms Laboratories Drug and tissue storage
Energy efficiency Rising utility costs
Regulatory requirements Critical alarm dispatching 24/7 monitoring Fresh air rates Lighting control HEPA filter monitoring

BMS is for and can : Operate, Monitor, Control, Optimize, Schedule, Integrate etc. all the equipments and systems covered under it’s scope.
BMS is not for and cannot : Alter equipment’s/ Technology’s basic efficiency.

Simple Strategies to enhance Energy Efficiency…some examples
Schneider Electric – Chandrashekar TV
12
Pharmacy Controls Example….1 Temperature Control Access Control Digital Video
Use the card reader to track occupants and interface to the HVAC when the pharmacy is unoccupied as the trigger to reduce HVAC energy usage. Schneider Electric – Chandrashekar TV
13
Pharmacy Controls Example….2
Access controlled by card readers Video image is attached to each access event Egress controlled by card readers Video image is attached to each egress event Access records stored and tracked Today digital video imaging can act as the occupancy sensor Security System knows when the space is vacant and sends this information to the HVAC control system to trigger the unoccupied Heating, Cooling, Ventilation and Lighting modes to save utility usage
Schneider Electric – Chandrashekar TV
14
Operating Room Controls Example
Operating rooms use large quantities of tempered air. In unoccupied mode air changes can be reduced but accurate pressure control maintained. Schneider Electric – Chandrashekar TV
15
Patient Room Controls Example Building Automation System (Inside conditions : Occupied/Unoccupied) Nurses Call Patient Monitoring Lighting Control system

Other Important Benefits of BMS
Schneider Electric – Chandrashekar TV
18
Remote Access
View live or recorded video Open or lock a door Grant access to service technicians for emergency situations Manage visitors
Take immediate action, 24/7, to solve problems Schneider Electric – Chandrashekar TV
19
Data Logging and Reporting
Certain compliance reports are based on logging of data Temperature Humidity Pressure Air Changes Alarms Non-BAS critical data (Critical systems/supplies)
BAS have the capability of logging and storing any of these values . . .by the minute, hourly, daily, change of state and on alarm conditions Schneider Electric – Chandrashekar TV
20
Logging/Alarm Examples for Hospitals
Isolation Rooms
Differential Pressure Positive/Negative Door Open Air Changes
Pharmacy
Drug Storage Temperature Warming Boxes Refrigerators Freezers Access Records/Video

Temperature Humidity Air Change Rates Differential Pressure
Blood and Tissue Storage Storage Room Temperature Refrigerators Freezers
21
All these benefits are derived from Integrated Building Management System
Schneider Electric – Chandrashekar TV
22
Conventional Architecture
Each building system is installed on a unique workstation using a unique communication platform
Multiple workstations does not mean interoperability! Schneider Electric – Chandrashekar TV
23
Integrated Architecture
Full interoperability, less IT infrastructure and lower life cycle costs Schneider Electric – Chandrashekar TV
24
Integrated BMS Helps Reduce CAPEX… up to 25% One common IT backbone One IT architecture for Data, VoIP, BMS: One common cabling system Reduced implementation time Dramatic reduction in installation costs
Reduction of redundancies One device for a multi purpose Ex : Same sensors or controller for access, lighting, HVAC
Reduction of needed resources One project gathering different functions Optimize resources (project management, resources on site, training, commissioning) for building management, security, electrical distribution
Schneider Electric – Chandrashekar TV
25
OPEX Reduction is Easily Feasible … up to 30% Energy saving : optimization of consumption thanks to better utilization according to presence. Interoperability of systems : access, lighting, HVAC Runs when necessary and on-demand
Radically reduced maintenance One single cabling system simplifies installation All information available for fast problem detection and correction
Remote technical services Reduced cost for upgrades Modification of control done through software only Remote services Remote meter reading, building management reports
Improved safekeeping High performance CCTV system
Schneider Electric – Chandrashekar TV
26
Integrated BMS Operation & Maintenance Benefits Single Source for service Improved response time Removes need for multiple service agreements and providers
Maximum energy savings Energy management and control systems Demand controlled ventilation Lighting Access Controlled Operation
Reduction of cabling One IT architecture for Data, VoIP, BMS Less time for implementation
Schneider Electric – Chandrashekar TV
27
Peace of Mind…
Maximization of power availability Resilient architectures Quality of products Services to sustain performance
Improved continuity of service, availability and reliability Interoperability between control, Genset, UPS, transfer switches…
Better safety management Traceability ensured thanks to record of all events of utilities
Better risk mitigation Pre-validated solution, pre-commissioning, monitoring Existing maintenance plan and process
Compliance with Health regulations
Schneider Electric – Chandrashekar TV
28
Improved Hospital Business Performance Comfort of patients Improves patient sense of well-being and healing times
Automation of functions Better staff productivity
Easy access to information Find origin of failures Fix the problems
Reduction of construction time Less cabling Factory built and pre-tested equipment

Case Study - IBMS University of Chicago Hospital One access badge per employee for five building campus CCTV installed throughout the campus Theft of scrubs, cafeteria food, and destruction of property closely monitored and therefore prevented Active alarms immediately emailed to staff Created “nested” parking strategy; parking garage became top revenue generator Infants are tagged; cannot leave designated areas Critical building pressure gauges are also monitored (air, water, steam, lab vacuum) “Medical Gases Tank Farm” is monitored including oxygen and nitrogen nitrous oxide Domestic hot water temperature controlled to 120°F
Schneider Electric – Chandrashekar TV
31
Case Study - IBMS Massachusetts Eye & Ear Infirmary Medical gases, steam pressure and building pressure are monitored Discharged water monitored for alkalinity levels Critical alarm monitoring including emergency generator oil tank levels, water pumps, AC unit failures, fire alarms, emergency power generator status Single button shutdown for entire facility in event of bio-terrorist attack Data center monitored for temperature, humidity, utility power, generator power, AC unit failure, water, fire Surgical level OR temperature, humidity, IAQ, and pressure Chiller plant control Temperature and humidity controlled throughout facility
