USGBC members developed LEEDTM, the Leadership in Energy &Environmental Design RATING system, for designing, constructing andcertifying new and existing commercial, institutional and high-rise,

residential, sustainable buildings.The tool can help the building industrytransform its practices and procedures into a holistic team effort thatwill be more able to design, build, operate, use, maintain and sustain anenvironmentally friendly efficient building. Based on well-founded

scientific standards, LEEDTM emphasizes state-of-the-art strategiesfor sustainable site development, water consumption, energyefficiency, materials selection and indoor environmental quality.

LEEDTM

’s comprehensive system offers proven standards, training,technical assistance, professional accreditation and web-basedresources (www.usgbc.org).

The LEEDTM RATING system is a self-assessing system to guide project development.There are four levels of certification:

The U.S. Green Building Council (USGBC) is

leading a national consensus for producing a new

generation of buildings that deliver high economic

and environmental performance. Council mem-

bers are a coalition of leaders from across the build-

ing industry working to promote buildings, which

are environmentally responsible, profitable and healthy places to live

and work. The coalition develops industry standards, design practices

and guidelines, policy positions and educational tools that support the

adoption of sustainable design and building practices. Many communi-

ties, state, Federal agencies are using LEEDTM CERTIFICATION in

local building codes.

WHO IS CALMAC MANUFACTURING CORPORATION AND

HOW MAY CALMAC’S ICEBANK® OFF-PEAK COOLING

CONTRIBUTE TO THE ACHIEVEMENT OF LEEDTM CREDITS?

CALMAC is a USGBC member company and actively participates in various localchapters. Globally recognized as the leader in the Off-Peak Cooling market, CALMAC manufactures an innovative and well-proven Off-Peak Cooling system, which utilizes iceThermal Energy Storage (TES), to air-condition facilities. Customers include The DurstOrganization, Mercedes-Benz, IBM, Wang, American Airlines, McDonald’s, JC Penney,

Underwriters Laboratories, Mary Kay and Marriott Hotels.

Thermal Energy Storage, or Off-Peak Cooling, is a proven energy conserving technologythat uses off-peak electricity to dramatically reduce the cost of air-conditioning. Efficientnighttime energy is used to produce and store cool energy in the form of ice.The stored coolenergy is used the next day for air-conditioning or process cooling during periods of peak

energy demand. Shifting the energy usage from on-peak to off-peak reduces energy cost andhelps stabilize the electric grid in areas of short supply, helping to avoid blackouts.

TES is friendly to the environment because the technology saves valuable source energy (theenergy used to make electricity at the power plant) and reduces emissions. This is becauseoff-peak electricity is more efficient to generate than on-peak electricity.

HOW TO QUALIFY FOR POINTS IN THE ENERGY AND ATMOSPHERE CATEGORY

Integrating off-peak cooling into a building design can help qualifya building for LEEDTM points by increasing levels of energyperformance above the prerequisite standards to reduce environ-mental impacts associated with excessive energy use. Points can be

obtained by demonstrating that the proposed design energy costs arelower than the base energy cost budget for regulated energycomponents described in section 11,page 59 of the ASHRAE/IESNAStandard 90.1-1999. ASHRAE 90.1 chiller plant efficiency standardsfor the energy cost budget are very lofty and fuel changes are notallowed.These stringent standards and rules make ice storage one of the major ways to reduce cooling operating costs. Lower designenergy costs can be demonstrated via a whole building simulation

computer program using the ASHRAE Energy Cost Budget Method.Off-Peak Cooling technology has proven to be a sustainable,reliable,cost effective strategy to reduce energy costs.

Depending upon the electrical rates, building usage and the Off-PeakCooling design criteria, points are awarded for reducing theproposed design energy cost of the facility as compared to thedesign’s ASHRAE energy cost budget standard on the basis listed

below. Off-Peak Cooling can provide significant reduction incooling costs over conventional cooling systems because the systemreduces electric demand and/or uses cheaper and more efficientnighttime electricity.

POINT AWARDS FOR REDUCING DESIGN ENERGY COST OVER ENERGY COST BUDGET

ASHRAE defined regulated energy components include HVACsystems, building envelope, service hot water systems and lightingetc.Ways to reduce design energy cost over the energy cost budgetinclude optimizing those regulated items. CALMAC IceBank®

Off-Peak Cooling systems can affordably be applied to the reductionof design energy costs. Efficient off-peak electricity generates andstores cooling for use during the next day’s peak demand times.

“Cool storage technology can be used to significantly reduce energy costs by allowing energy-intensive,electrically

driven cooling equipment to be predominantly operated during off-peak hours when electricity rates arelower. In addition, some system configurations result in lower first costs and/or lower operating costs comparedto non-storage systems…cost effective applications also exist without the benefit of time of day electricalrate differential."

This is a simple guide for building owners, engineers, archi-

tects who are interested in sustainable high

performance buildings and how Thermal Energy Storage

(TES), or more descriptively known as Off-Peak

Cooling (OPC), can help with the U.S. Green

Building Councils’ LEEDTM CERTIFICATION program. The

LEEDTM RATING system will be summarized in this guide

with focus on how off-peak cooling can help accrue

valuable points in the Energy & Atmosphere and

Innovation & Design credit areas.

Off-Peak Cooling using ice Thermal Energy Storage (TES) is an effective and affordableHVAC cooling strategy for today’s sustainable green building designs. Off-peak cooling isa proven technology that can dramatically reduce design energy costs while benefitingsociety. Off-peak cooling has a benefit beyond the electric meter because it uses existinggenerating assets more efficiently, slowing the need to build more generation. OPC savesvaluable source energy for future generations and reduces greenhouse gas emissions for ahealthier environment.

LEEDTM points may be obtained by installing CALMAC IceBank® tanks. The tanks andother Off-Peak Cooling system components can be installed without an increase in first costin some cases and with a minimal first cost premium in many others.

LOWER FIRST & LIFE-CYCLE COSTS

An energy-efficient building design does not have to cost more thanstandard construction. An integrated LEEDTM design creates synergy

between design disciplines, technology for construction and operatingcost savings. For instance, TES (Off-Peak Cooling) can reduce coolingcosts by as much as 40% and overall electric utility operating costs

from 10% to 25%. A good partial storage TES design can enable thedownsizing of some HVAC and electrical equipment such as chillers,condensers, cooling towers, pipes, fans, coils, motors and pumps,thereby saving on installed costs.

Off-Peak Cooling may well qualify for one of the five Innovation &Design (I&D) credits because it reduces building electric demandrequirements while benefiting society. In numerous studies, mostnotably one requisitioned by the California EnergyCommission (CEC), it has been proven thatelectricity is produced and delivered much moreefficiently during off- peak hours than during on-

peak. For every kilowatt-hour of energy that isshifted from on-peak usage to off-peak there is areduction in the source fuel needed to generate it.Although the exact amount of savings varies, a CECstudy showed a range from 8% to over 30% for 2 of the major utilities studied. A similar study has beendone for the PJM Power Pool area.

Reduction in source fuel normally results in areduction of greenhouse gas emissions produced bythe power plant.The peak load reduction benefit alsohelps lower the load on the electrical grid, minimizingthe need for new power plants and peak load reduc-tion helps keep the grid stable in periods of crisis. Not

evident to the particular buildings’ electric meter or the energy studydone by the engineer lowering design energy costs is another benefit of Off-Peak Cooling.

HOW TO QUALIFY FOR A POINT IN THE INNOVATION AND DESIGN CATEGORY

The Hewlett Foundation Building in Palo Alto, CA is that State’s first recipient of the Gold LEED™CERTIFICATION due, in part, to CALMAC Off-Peak Cooling.The building is about 40% more efficient thanrequired by California’s current energy code.
