Engineering Analysis

● Engineering Analysis Presentation: Cost/Efficiency Curves (PDF 

374.6 KB) 

● Commercial Building Energy Use and End Use Load 

Characterization Analysis Presentation (PDF 3.8 MB) 

Life Cycle Cost Analyses

● Life Cycle Cost Analysis Spreadsheet Model (Tariff-Based Electricity 

Prices): DOE uses the tariff-based Life Cycle Cost (LCC) Analysis 

Spreadsheet Model in the commercial unitary air conditioner 

energy efficiency standards rulemaking for calculating annual 

electricity expenses that are based upon electricity prices 

determined from electric utility tariffs. DOE has revised the tariffbased LCC Spreadsheet Model since it was first posted to this 

website on March 31, 2003. DOE has now based this LCC 

Spreadsheet Model on electricity price forecasts from the Energy 

Information Administration's 2003 Annual Energy Outlook. (Excel 

8.7 MB) [revised 7/24/03] 

● Life Cycle Cost Analysis Spreadsheet Model (Hourly Based 

Electricity Prices): DOE uses the hourly based Life Cycle Cost (LCC) 

Analysis Spreadsheet Model in the commercial unitary air 

conditioner standards rulemaking for calculating annual electricity 

expenses based upon electricity prices determined from hourly 

electric utility load and cost data. DOE has revised the hourly 

based LCC Spreadsheet Model since it was first posted to this 

website on March 31, 2003. DOE has now based this LCC 

Spreadsheet Model on electricity price forecasts from the Energy 

Information Administration's 2003 Annual Energy Outlook. (Excel 

4.1 MB) [revised 7/24/03] 

● Life Cycle Cost Analysis Presentation: Inputs and Results. DOE has 

revised the Life Cycle Cost (LCC) Analysis Presentation since it was 

first posted to this website on March 31, 2003. The revised 

presentation reflects the updated life cycle cost analysis that uses 

electricity price forecasts that are based on data in the Energy 

Information Administration's 2003 Annual Energy Outlook (AEO).

National Energy Savings

● National Energy Savings Spreadsheet: The National Energy 

Savings (NES) Spreadsheet model is a tool for determining the 

shipments impacts, national energy savings, and national net 

present value resulting from higher efficiency standards for certain 

commercial unitary air conditioning equipment. DOE has revised 

the NES Spreadsheet since it was first posted to this website on 

March 31, 2003. The revisions to the NES Spreadsheet include: (1)

Appliances & Commercial Equipment Standards: Commercial Unitary Air Conditioners and Heat Pumps

basing future electricity prices, commercial building starts, and 

electric utility generation facilities on forecasts from the Energy 

Information Administration's 2003 Annual Energy Outlook; (2) 

adding the capability to analyze national consumer impacts from 

near-immediate adoption of the American Society of Heating, 

Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE)/

Illuminating Engineering Society of North America (IESNA) 

Standard 90.1-1999, "Energy Standard for Buildings Except LowRise Residential Buildings," energy efficiency levels; and (3) using 

a single set of assumptions, rather than a multiple set, to forecast 

commercial unitary air conditioner energy efficiency trends. (Excel 

6.2 MB) [revised 7/25/03]
