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

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

Kapoor, Ravi. Kumar, Satish. (2011). Energy Efficiency in Hospitals: Best Practice Guide. New Delhi, India.

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
