APPENDIX E: LIFE-CYCLE COST RESULTS AND DETERMINATION OF 30-YEAR

AVERAGE COOLING DEGREE DAY AND HEATING DEGREE DAY DATA

E.1 LIFE-CYCLE COST RESULTS

This appendix provides the frequency and cumulative distribution charts of the life-cycle cost

(LCC) results for all the efficiency improvement levels analyzed for central air conditioners and heat

pumps. For details on the methodology used to calculate the LCC refer to Chapter 5.

The four sections that follow present the LCC results for each of the following four primary

product classes: split system central air conditioners, split system heat pumps, single package central

air conditioners, and single package heat pumps. The LCC results are based on the use of ARI

manufacturer cost data. In each section, results are presented for efficiency levels of 11 through 13

SEER and 18 SEER (i.e., “max tech”). For each efficiency level, frequency and cumulative charts

are provided showing the distribution of expected LCC differences from the baseline design.

E.2 DETERMINATION OF 30-YEAR AVERAGE COOLING DEGREE DAY AND

HEATING DEGREE DAY DATA

The determination of 30-year average (1961 to 1990) cooling degree day (CDD) and heating

degree day (HDD) data for the nine Census Divisions and four large states (i.e., New York, Florida,

Texas, and California) is based on weighting representative weather station CDDs and HDDs by a

combination of 1) population data and 2) the estimated central air conditioner and heat pump

shipments to the weather station region. 

For each of the nine Census Divisions and four large states, Tables E.1 through E.13 show

how the 30-year average CDDs and HDDs were determined. Starting with representative weather

station cities, the population of each weather station is determined. Then, knowing the shipments

per state, the shipments per weather station are determined based on weather station population.

With the CDD and HDD known per weather station, a shipment weighted calculation is performed

to determine the weighted-average CDD and HDD. 

Shipments per state are based on data provided by the Air-Conditioning and Refrigeration

Institute for the years 1992 through 1994. Weather station population, CDD, and HDD data are

based on data from the National Oceanic & Atmospheric Administration.
