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

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

Current building management is inefficient

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.

Submeters are the solution

Submeters Are The Solution

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

Benefit 1

Track and Optimize

Energy Usage


Step One: Look for disparities in trends

6

Real time information can be used to save moneyTrack & optimize energy usage


Step One: Look for disparities in trends– Why is my nightly usage so much higher for some nights of the week?

6




Step Two: Question why the disparities exist– Were lights or HVACR units left on at night? Individual metering will determine which system is

responsible for discrepancies

6





responsible for discrepancies Step Three: Come up with fair, indisputable solutions for disparity

– Install timers for automatic on / off of lighting, HVACR units at certain points of day / night

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

Benefit 2

Tenant Specific Billing

http://www.nyserda.ny.gov/-/media/Files/Publications/Case-Studies/MEPP/tower-east-cs.pdf


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.

Benefit 3

Fault Detection

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!8

M&V for New

Systems Savings

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

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

Now is the time to invest!

* See Appendices for examples of New York submetering incentives. Please refer to your individual states list of incentives here.

The current US energy market provides a tremendous opportunity for financial gains through submetering

Don’t just take our word… NYC has written submetering into law Submetering to become mandatory in New York City by 2025 (Local Law 88)

Many cities and states will soon adopt similar rules (see Energy Star Leveraging Policies)
