A New Paradigm!

Energy Productivity: The total value of the energy

deployed

Energy efficiency is just one of the dimensions

- Negative connotations

Increasing Energy

ProductivityDecreases energy costs

-Directly affects the bottom line

Frees up Capacity of Existing Infrastructure

- Avoided cost of new equipment

Alleviates Maintenance Requirements

- Moving from reactive to proactive

Increasing Energy

Productivity! Improves Occupant Comfort and Experience

- Highly tuned building & systems

Decreases Exposure to Risk

- Utility budgets and market volatility

Positive public relations

- Recognition, partnerships, politically relevant

Conservation:

Jevon’s Paradox & Rebound effect:

Watt It’s Not!

The Takeaway!

We will forever be finding more and more uses for

energy

What is one of the biggest emerging uses of

electricity today?

Energy Costs!When Energy Consumption is Reduced and…

Energy prices stay flat:

Need to be Insulated from…

Price Increases

Weather Extremes

Budget Cuts

Energy Investments!

Investments not expenses

Cuts costs of business bottom line

Opportunity Cost- greater than market returns initially - external benefits of energy productivity

What to do With Returns?

Once project is paid off

- Residual energy savings captured

Revolving budget

- Used for reinvestment; yielding additional savings

Building momentum

Energy Information System

The software,

data acquisition hardware,

and communication systems

used to store, analyze, and display building energy

data.

Large upfront investment.

An EIS enables savings, rather than directly

.

Where to Begin Sub

Metering?Gather information

Is it going to be vacated in the next 5 years?

Is it under a certain size?

Is it a leased building?

Sub Metering

Meter everything else!

Significant capital, time, and resources needed

Various meter technologies for different applications

How granular does the data need to be?

Prioritization

Two types: by Building or by Utility

Complete energy info for high priority buildings.

Or some energy info for all campus buildings.

Based on the following factors:

Building Prioritization

Building size

Energy intensity

Auxiliaries

Metering effort coinciding with a major remodel.

Which Utilities to Meter?

Electricity

Heating Water

Natural Gas

Steam

Chilled Water

Culinary Water

Domestic Hot Water

Fuel Oil

Misc…

Example

Goal is to capture the complete picture of the

facilities energy and water usage.

Some critical thinking and knowledge of the facility

and its systems are required

Example

Data Management Plan

Automate data access and analyzation

Dashboards

Demo

Analytics

The discovery, interpretation, and communication of

meaningful patterns in data.

Answers the how and the why of energy usage.

Trends BAS system and sub metering data points

- Easily manipulated database

SkySpark

Processes all equipment operations and energy

usage data

- Automatically & retroactively

Compares it to specific rules programmed to

identify problematic equipment operations.

Equipment that violates a rule is “sparked”

- Instance is recorded for later viewing

Half of the Work

Computer processes data and finds problems

Human capital freed up to do the actual work

Ultimately creates more work

Helpful Suggestions

Map out your network

Discuss with IT what you desire

Dedicated network if possible

Keep on same Subnet if possible

Helpful Suggestions

Minimize switches and length of network cabling

Dedicated IP address to each device

Set up for VPN and remote logins

Keep secure and review security policies

What it Helps Us Do

Analysis methods:- Baselining & Benchmarking- M&V- Carbon footprint - Load profiling- Energy anomaly detection.

Finding and eliminating energy waste with low cost

measures- Scheduling- Commissioning- Peak shaving- Occupant or operator practices.

Benefits

Evaluate Real time Data on a daily basis

Maintaining energy performance improvements and

efficiency gains over time

Identify opportunities for optimization

Purveyors of Change

One caveat: Maintaining the nature of the

organization

Information and Technology

Approach and Methodology

Education, training, and outreach

Hurdles

Design -Researched other institutions get an idea of what is wanted, who can provide it, etc. - Outside Expertise

Procurement - Getting exactly what is wanted, not low bid alternates

IT support - Understanding concerns and cooperating

Hurdles

Institutional commitment

Stakeholder Engagement

Dedicated personnel

Hurdles

Budget Constraints

Personnel training

Data Loss, accuracy, and information overload

Cost calculations and billing

Struggles & Limitations

Energy drift

- Must always be combatted to maintain high

performance

Law of diminishing returns

- Equilibrium point i.e. supply and demand

Struggles

Reputation

Mentality

Data Driven Decision Making

Shifting big energy consuming activities to off peak

Building specific load profiles to identify norms of operation

Provide visibility to understand what is driving energy spend

Prioritize investments/capital upgrades

M&V at the building/system level

Employee Engagement

Participation and awareness of the bottom line

Accurate Forecasting/Procurement

Environmentally sustainable

CSR

Benefits

Capacity freed up

Enhanced competitiveness/resiliency

Billing auxiliaries and customers

Benefits

Maintenance moves from reactive to proactive

No more surprise energy bills

Utility budgets insulated

Building momentum with institutional investments in

energy
