Key Input Summary for LPD BundleKey Input Summary for LPD BundleItem Methods & Sources

Energy Savings Calculation Engineering Estimate: Savings in Watts/sf * Hours * Savings Yield for Space Heat Interaction

Applicable StockFloor Area Forecast by building type & vintage cohort. Lighting turn-over rate is relatively high for lighting so most potential is in natural replacement (NR) case. Lighting system lifetime ranges from 8 years for retail to 20 years for warehouse and schools.

Baseline LPD New Building Baseline 2002-2004, NEEA

Target LPDJudgment based on: Best examples in NEEA New Building Baseline 2002-2004, Case Studies, Program Data, PIER, & Design Guidelines

Hours of Operation Various sources modified by national Lighting Market Characterization from 2002 by Navigant (LMC)

HVAC Interaction FactorsOriginal data of 09-11-2003 from Ecotope with 10/21/2003 addendum from Kennedy on schools and 12-16-2003 hours addendum from Grist

MeasuresSuite of 6 proxy measures is based on frequency distribution of existing equipment by source and fixture type for each building type and vintage. Existing equipment saturations from NEEA stock assessment.

Capital CostsUnit costs based on data from US DOE 2008 ANOPR rulemaking on general service fluorescent lighting, website prices, labor and markup. Costs are normalized to $ per change in lighting power density.

Periodic Replacement CostsUnit POM costs are based on equipment and labor cost for lamp and ballast and replacement and the frequency of replacement based on equipment life and annual operating hours by type.

Savings Shape ELCAP lighting savings shapes by space heat type

Measure Life Same as system turnover rate; 8 to 20 years depending on Btype.
