§ MOU on collaborative research for clean
energy innovation with measurable results and significant reduction in buildings energy use in the U.S. and India.
§ Leapfrog technologies in India; Demonstrate in Indian buildings; Apply results in U.S.

Technology, India § Schneider Electric § Wipro Eco-Energy § Mazzetti
EIS-in-a-box packaged solution From custom-built to cutomary practice
Technical requirements for packaged, scalable, cost effective, sector-wise “EIS in a box” for the U.S. (underserved building sectors) and India (emerging market) Help scale applicability and use of EIS to encourage widespread adoption
§ 3 elements (1) Meters (2) Gateway (3) Software & UI § 2-tiers (1) Entry (2) Advanced § 3 target sectors (1) Hospitality (2) Healthcare (3) Offices
Packaged or custom?

Package Custom EIS
§ Simpler, cost- effective packages have some tradeoffs compared to sophisticated, custom built EIS solutions, but the latter may be excessive for many, underserved organizations
§ Entry (Tier 1) and Advanced (Tier 2) packages mapped to energy-related business drivers
1. Tradeoffs by package tier based on cost, functionality, flexibility
What makes current EIS solutions expensive? A characterization of transactional cost
Step 1:
Make executive decision Secure customer
Step 2: Define biz drivers, KPIs
Design engineering mapped to organizational KPIs
Step 3: Procurement (RFP)
Product fulfillment, integration, configuration, testing
Step 4: Installation, Commissioning
Sub-contractors for installation
Step 5: Training and Ongoing Use
Key red: client -side activity and associated cost blue: vendor-side activity and associated cost (passed on to client)
3) Select Target Segments 1) Screen Characteristics 2) Define Segments
How did we pick the three target sectors? Market segmenta@on and analysis
§ High growth sectors § High EUI in the sector, with energy saving opportunities § Need for EIS penetration of stock buildings in these sectors
Hospitality Healthcare Offices

Sector-wise EIS offering: Healthcare sector Key findings on sub-sector and energy use
§ Order of magnitude higher energy consumption, and bigger savings opportunities. US trend towards outpatient facilities, and energy efficient design India trend towards inpatient, acute care with US levels of service/ patient delivery; high growth
§ Heterogeneity within sector: Acute Care, Ambulatory Care, Skilled Nursing… § Additional healthcare specific metrics (KPIs), e.g. EUI/bed, or EUI/adjusted patient day. § Gateways similar to those in the hospitality package, but metering expected to be different,
given the diversity, complexity and criticality of spaces, systems and equipment § Not all large loads may be controllable. Many are highly regulated by healthcare agencies.

Derivation of “Picklist of Loads” in the healthcare package
Sector-wise EIS offering: Healthcare sector Exhaustive analysis of recommended metered points
Is the load contributing to major consumption? CONTRIBUTION (Y/N)
Is the load available to control/ schedule? ACTIONABLE (Y/N)
Can the load be sub-meter discretely METERABLE (Y/N)
Load 1, e.g. “ Zone Ventilation”
Load 2, e.g. “Operating Theater Lighting
Load 3, e.g. “Imaging Lab”
Load 4, e.g. “ Diagnostic & Treatment Rooms:”

Next Steps
1. Finalization of Healthcare EIS package 2. Demo of Hotels package in 2 Indian business hotels
§ Package technical requirements adopted by commercial partners § Package evaluation according to assessment criteria § Package results transferred to US facilities
3. Initiate EIS for Offices package
