COST & SAVINGS

MYTHS IN MARKETING

How do you accurately present energy savings? Easier said than done. The intent of this overview is to separate fact from fiction and then apply it to real world applications. The marketplace is loaded with myths, misconceptions and misrepresentations. It does not matter whether this is intentional or not, eCOOLogy's intention, is to provide real world information and let you, the building Owner, be the judge.

Savings are often marketed by %, often claiming 20%-90% savings. The question should be: Savings for what, and how does that translate to actual dollars spent or saved? As percentages are determined after the fact, not before, we would caution against subjective savings claims.

Actual reductions in $$$ is predicated not only by occupancy use, but electric rates. Peak rates will vary between summer and winter, between utility providers and between their respective residential and commercial customers. Commercial rates will vary between individual customers. In addition, you have to figure in demand charges which can be the most costly. Demand charges are relative to time of usage and peak usage, during a given time of the day. How can anyone arbitrarily claim a percentage of savings? Are they talking about 20% to90% of what dollar figure? If you reduce you business operations by 25%, reduce lighting by 40% and turn off your air conditioning for a month, your savings may be as high as 70%. The problem is that it may have had little or nothing to do with your investing in a roof cooling solution.

Savings by % has no real bearing on a Payback Period or Return On Investment (ROI). True energy savings are determined by the relationship between the cost of the proposed energy savings solution or devices and the payback period to recoup your initial expenditure. The industry standard for an optimal payback period, for energy savings solutions or devices, is 18-30 months, with periods of up to 48 months being acceptable in some cases. Solutions or devices with an ROI range of 40% - 60% are most desirous.

This energy reduction chart provides a picture of the value of the Ecoology system on an hourly and daily basis. Based on years of scientific study, it can be reasonably estimated what the usage of water will be. This is shown on the chart for the size building under consideration. Individual building configurations, occupancy usage and utility rates will determine installed ESI system cost, savings and payback periods. For a detailed analysis for your individual building utilizing your own utility rates, contact eCOOLogy.

ADDRESSING THE BUILDING ENVELOPE

eCOOLogy manufactures patented “Building Energy & Asset Management Systems”. With the advent of ever rising energy costs, many popular roof related approaches / proposed solutions are principled in reflecting rather than dissipating heat. Most all approaches initially reduce utility costs. It is their collective impact on sustained utility reduction, the roof system and roof level cooling equipment that needs to be included. For any financial model to properly assess these items, a baseline standard for criteria needs to be established.

Envelope: For uniform assessment for building information including foot print, height from slab to roof, number of floors and construction for walls, roof framing and roof deck.

Roof System: Establish the existing or proposed roof system by components, anticipated life and warranty. This includes insulation board or insulation below the deck.

Mechanical Equipment: The roof level mechanical systems based upon standard HVAC units with either top or side air intakes. The model configuration should reflect typical capacities and number of units for this type of occupancy.

Roof Cooling System: Roof cooling systems are based upon two technologies, Re-Active and Pro-Active. The eCOOLogy PAIR system reduces transfer of roof heat and extends roof and mechanical life.:

OVERALL SAVINGS: ENERGY & ANCILLARY

True Cost, Savings, Payback Period and Return On Investment (ROI) can only be realized when financial models represent the interaction / impact between sustained utility reduction, the roof system and roof level cooling equipment.
