ENERGY MANAGEMENT SYSTEM

Energy sources The main source of almost all heat and light energy on Earth is the sun! The sun is an important source of energy Energy from the sun is called solar energy

Energy Efficiency and Energy Conservation �Energy efficiency involves the use of technology that requires less energy to perform the same function. �Energy conservation is any behavior that results in the use of less energy �Mandated efficiency improvements for refrigerators in the 80’s have provided energy savings equal to 40 large power plants.

“ENERGY MANAGEMENT” MEANS LOWERING COST BY: �ELIMINATING UNNECESSARY ENERGY USE �IMPROVING THE EFFICIENCY OF NEEDED ENERGY USE �BUYING PRICES ENERGY AT LOWER NET �ADJUSTING OPERATIONS TO ALLOW PURCHASING ENERGY AT LOWER PRICES

STEP 1 Identify ALL Your Opportunities � Unlike most other business activities, you need a formal process, usually called an “energy audit”, to find all your opportunities. �A good “energy audit” takes time and costs money, but not much of either, compared to your overall program

� The energy auditor requires scientific and engineering education, broad practical experience, and solid judgement. � The energy auditor needs a thorough understanding of ALL opportunities, not just a few.

STEP 2 Prioritize Your Activities Rationally � The sequence of your activities is a major factor in the economic benefit of your energy management program. � Consider all the criteria that matter, not just the economic criteria. � Calculate with realistic numbers. � Limit consideration to measures of proven reliability. � Consider the ability of your staff to accomplish and maintain each measure.

STEP 3 Accomplish Your Activities Properly � Each cost saving activity is an independent project that requires its own knowledge, equipment, and people. � The key to success is doing your homework before initiating each activity.

�The Response of energy management system � �� Development of an Energy. Management Standard ANSI MSE 2000 � �� 2005 Stakeholderdiscussions in the US, and. Internationally, ANSI MSE 2000: 2005 issued. � �� 2006 Internationalstakeholders engaged in discussions � �� 2007 Stakeholders meeting(UNIDO) determine international standard needed

STEP 4 Maintain Your Activities Endlessly � Almost nothing continues to operate successfully by itself. � Each energy management activity requires continuing support. � Integrate the maintenance of each activity seamlessly into your overall operations.

�Your program will be a success when the top managers of your organization understand that energy management produces the highest profits in the organization.

Heat Transfer Heat is a form of energy When heat moves from place to place, it is referred to as “heat transfer” Heat transfer occurs in three ways: Conduction Convection Radiation


Before starting any energy or deregulation program: Understand your load profile Annually Monthly Daily

Energy Reduction Measures that Work: Management Programs t 8 lamps Electronic ballasts LED exit signs Reflectors Occupancy sensors Daylighting control “Energy Task Force” employee awareness program: Preventive maintenance Operator Training Metering Commissioning

Electricity Generation By Source Renewables Fuel Cell Hydro Solar Wind Biomass

Solar Photovoltaic Stand alone utility connected Supplemental building systems Integrated building technologies – roofs Very expensive Prices expected to come down with more production Incentives are available Can be attractive if far from the utility grid

Wind Energy Large Scale Wind Energy Projects Small Scale Projects Similar constraints as solar

Energy Management Review Charge the design team with developing properties with high energy efficiency as a goal Use life cycle costing for determining options Make energy decisions early in the project Commission energy systems prior to opening Consider energy plan review

Ten Items You Can Do to Improve Energy Security �Recognize that Energy Security is an issue and develop a plan �Identify a command center and insure that critical components have emergency power �Identify all sources of energy and the location of shut off devices �Develop communications plans for customers, tenants and employees �Identify the source of off-site energy sources and a list of utility contacts

Energy Management § Mike Carter § Mark Farrell Energy Management Benefits Bottom line cost savings today! Energy. Maintenance Reduced noise levels Better indoor air quality Reduced air emissions

Energy Management Opportunities Basics Energy Management Insulation HVAC Lighting Heating Systems Motors Transformers Compressed Air

Corporate Energy Management Key Components of Energy Management Commitment by upper level management Clearly stated goals on energy efficiency, waste reduction, and sustainability Delegation of responsibility and accountability to the appropriate personnel Sustained tracking and assessment of energy use and technology application Continuous investigation of potential energy reduction projects

HVAC Upgrade Older HVAC (10 to 15 years) Chillers: 0. 8 k. W/ton 0. 5 k. W/ton (37% less!) Unitary rooftop: 1. 5 k. W/ton 1. 2 k. W/ton (20% less!) § Geothermal or Water. Source Heat Pump • Roughly 30% savings • compared to AC/Boiler or AC/Furnace combination Geothermal requires higher capital investment and requires significant amounts of real estate ØNew construction accommodates verticals and pond loop

Energy Management Conclusions �Utilities are a controllable expense �Energy management pays off �Develop a program and take care of the details first �Deregulation is here, now �Understand manage risks �Landlords have unique issues �Get involved in the process or get left behind

The Best Energy Management Program Will Have: ◦ An Energy Master Plan ◦ Well trained and motivated owners, staff and contractors ◦ A dedication to preventive maintenance ◦ An energy procurement strategy ◦ Optimized equipment based upon life cycle costing. I. e. Lighting, HVAC and Building ◦ Up-to-date, functional Controls and Information Systems
