Why get involved with submetering?
Picture Source: Shutterstock
Submeters can be installed on any utility-connected system
and allows for better building management
Submetering Allows You to Maximize, Minimize & Optimize:
Maximize Building Value
– Precise tenant billing
– Multiple budgeting options
– Detailed procurement strategies
Minimize Energy Usage
– Reduce OPEX
– Increase cash flow
– Enhance equipment performance
Optimize Building Intelligence
– Analyze usage trends
– Institute fault detection and predictive
maintenance plans
– Free up work force for other tasks

3.  30% of energy usage within a building is wasted!*
 High and rising energy rates, status quo building management, and reactive rather than proactive
maintenance on systems results in wasted energy and a large opportunity for savings
 Tenants who are not being charged for electric & other utilities based on their actual usage are likely
to be using it irresponsibly, increasing overall cost to building owner and responsible tenants.
Submetering can help resolve landlord-tenant disputes.
 Systems may be running inefficiently or unnecessarily
 Utilities monthly readouts supply data after the fact and do not
give accurate portrayal of daily usages, do not help in measurement
and verification (M&V) of potential savings from new systems
 Cannot participate in market and utility programs without submeters

4.  Submetering allows for building owners to accurately and precisely monitor their own
usages, cut down on waste reduce disputes, and invest in the highest ROI technologies for
their buildings
 Choose what you want to submeter (lighting, heating, cooling, refrigeration, overall tenant
areas, etc.)
 Submetering will encourage tenant changes resulting in savings of 5-15% of energy bill
– Has one of the best ROI’s among energy efficiency technologies (typically ≤ 3 years)
– Panoramic Power reduces The North Face’s energy usage by 10%, ROI < 18 months
 Submeters are ideal for any building type – hotels, hospitals, schools, multifamily buildings,
etc.

6. Real time readouts reveal
valuable trends throughout
hours / days / weeks / months
 Show irregularities within certain timeframes
– Gives information on waste through trends and individual tracking of systems (AC unit
kept on at night, in winter, etc.)
 Can be used as a secondary measurement tool to make sure you are being charged
correctly by utilities and / or landlords, resolving costly disputes
 Can be used as an informational and educational tool for building residents / tenants
– Dashboards show real-time data to tenants and all within building, making everybody
more conscientious of usage

12. High electricity costs creates a need
for accurate, tenant-specific
electricity metering and billing
 Tenants can now pay for what they are using rather than a bulk price included in rent
– Reduces potential disputes & litigation costs
– Makes building more appealing to potential tenants
– Makes tenants more conscientious and stringent on usage, cutting down on owner’s costs
 Tenants now also have accurate portrayal of usage and potential solutions for reducing
individual use
 A NYSERDA case study of submetering results in ~20% reduction in tenant electricity
consumption within a building

13. Be Proactive, not Reactive!
Facility managers will be alerted
when systems aren’t operating
efficiently or properly
 Supports Fault Detection Diagnostics (FDD) and Predictive Maintenance
– Identifies issues prior to failure (overheating, leaking, systems in need of repair or maintenance)
– Prevents equipment failure and downtime in operations
– Keeps systems up and running and, therefore, tenants comfortable and happy
 Alerts and updates appropriate persons on required inspections, maintenance, etc.

14. Get instant, precise information &
detailed performance monitoring
on your real time energy usage
 Determines which systems are most energy-intensive
and have the most upgrade potential
 Enables contractors to give accurate numbers for ROI
and savings when installing new systems (M&V)
– Example: New heating system will save 10 % electric
usage / year, ROI of 4 years, guaranteed
 Helps to obtain points for LEED and ENERGY STAR ® certification
 New opportunities exist for building owners and contractors
– Building owners generate recurring revenue streams; Contractors engage in long term customer relationships
 M&V soon to be a mandate for future building improvements – become familiar now!

15. Better management of assets enables
access to revenue-generating
market and utility programs
 Demand response
– If utility (e.g. electric company) is under high stress during peak hours, it may ask you to reduce your demand
– Get rebates (typically ~$ 25 – 100 per kW reduced) for the hours of lower peak demand
– Submeters show best ways to reduce demand to help out utility
– Visit Con Edison Meter Upgrade Manual and Con Edison Metering Upgrade Application for more information and
application forms to join in demand response
 Dynamic pricing
– Price of utility rates rise during peak periods, pay an additional fee for time-of-use
• Higher prices during peak hours, lower prices during off-peak
– Allows building owner to decide to alter energy use during peak/off-peak periods

16.  Opportunities for savings exist based on government mandates, incentives, and rebates
– Rebates and incentives will not be around for much longer!
 New submeter technologies have more detailed and accurate readouts, enhanced
capabilities, and are dropping in price
 More installation opportunities due to new financing options and market & technology
education
