Agenda

The Need to be Green

Measuring Current Consumption

Benchmarking Are you considered efficient or not when compared with similar Businesses

Assessing Opportunities Rebate Programs

Examine Cost and Savings for Energy Conservation Measures

Lighting, Ventilation, Automation, Boilers, Chillers

Sanity Checks – Are savings projections realistic

“The least expensive and most environmentally friendly unit of energy is the one that is never needed!”

100 Watt Light Bulb run year round

This represents only about a 50th

of what a US household consumes

Today‟s technologies can reduce energy consumption up to 75%

Gas Utility - MCF of Gas

Heating

Cooking and Misc.

Hot Water

Measuring Current Consumption

Convert everything to mmBtu…

Gas – Total MCF

MCF = 1 mmBtu

Electricity – Total kWh

1 kWh = 3412 Btu

Divide by 1,000,000 = mmBtu

Example

1000 MCF = 1000 mmBtu

100,000 kWh = 341,200,000 Btu = 341.2 mmBtu

Benchmarking

Know the total square footage for you facility –

(example = 10,000 Utility = $225k mmBtu=1,341)

Calculate mmBtu per square foot

Example

Total mmBtu = 1,341

Total square footage = 10,000

Total mmBtu per square foot = .1341

Benchmarking

Typical mmBtu per square foot

Schools .03 - .08

Universities .10 - .17

Commercial .12 - .15

Industrials .12 - .25

Assume cost at about $1.1 per square foot

Assume savings at $.17 per square foot

Example – 10,000 square foot facility

$11,000 cost

$1,700 annual savings

LED Benefits / Concerns

Operational Savings

Reduced recycling costs, Extremely long life, Vibration and orientation proof.

Energy and HVAC Savings – Up to 50% in some cases.

Instant-on capabilities

0-100% dimmability

Color changing

Exceptional Lamp Lumen Depreciation

No UV, No IR, No Mercury

Small size allows for many new designs and ideas from the ground up that could not have been possible before.

Ventilation

Nearly 40% of your utility cost can come from

conditioning outdoor air

ASHRAE requirements allow for different control

Potential Savings = .02 mmBtu per square foot

Typically 2 – 4 year payback

Opportunities

Building Automation

Savings of 2% to 3% off total Utility

Retro-Commissioning also 2% to 3%

Cost is Low

Payback typically < 1year to 3 years

Control Strategies

•The first HVAC controllers were pneumatic

•The use of electromechanical relays in ladder logic, to

switch dampers became standardized.

•The relays became electronic switches

•By 1985, pneumatic control could no longer compete with

this new technology.

•By the year 2000, computerized controllers were common

•Today, some of these controllers can even be accessed by

web browsers and PDA’s?

Building Automation

„Energy Harvesting Technology‟

Innovative BAS Solutions will..

Preserve existing investments in control and monitoring

devices and integrate them with new standards-based

technologies.

Access and control through a standard web browser.

Combine information from different systems to support

better overall facility management.

Increase flexibility of vendor selection

Lower operational costs, improved facility operations,

reduced energy costs, increased occupant/tenant

satisfaction, and greater control, manageability, and

security of building operations.
