Rolf Butters Industrial Technologies Program Industrial Buildings Tools and Resources Webinar - June 11, 2009 Michael MacDonald Agenda Introduction to Industrial Buildings Opportunity and Tools EERE Funding, Opportunities, and Resources Next Steps 6/11/2009 2 Facilities Energy ITP has been working for a couple years now to develop tools to address facilities energy use, present in most plants, and about 8% of total sector energy use First tool is a Score Card, implemented both as a stand- alone Excel file and for QuickPEP 3 Score Card has to be simple, so is approximate 3 But it can be a very important tool for scoping facilities energy use at a plant Second tool is an adaptation of the BCHP Screening Tool, originally developed by the Distributed Energy program but now used extensively by FEMP for CHP screenings 3 This tool runs DOE-2.1e simulations to calculate savings Focus Small to medium size plants have a record from the IAC program, FY02-present, of: 3 3,878 assessments, 31,833 recommendations (28,425 were cenergy d), and 8,953 cbuildings energy d recs 3 Of the 8,953 buildings recs, 518 were on envelope, 213 were on ventilation, 6,806 were on lighting, and 1,416 were HVAC Total energy savings for ... more. less.

8,953 recs of 14.7 Trillion Btu/yr Over 2 billion sq ft in 50 states + PR Average plant 500,000+ sq ft, median plant 120,000 sq ft Generic Assessment Actions Obtain utility records / analyze costs Site/Building visit to collect data Energy accounting / Score Card Analyze potential measure savings Report ITP BP Tools website http://www1.eere.energy.gov/industry/bestpractices/software.html IFSAT Listing on same page Example You have completed the generic steps of: 3 Obtained utility data 3 Conducted site visit Now starting to analyze data: 3 Use Score Card to scope buildings energy 3 Use Score Card to scope building energy measure total savings 3 Use other tools, like IFSAT, for further calculations Notes We generally like to analyze utility data before site visit, but keeping flow simpler here for presentation cTypical d plant of 150,000 sq ft, about 4 million kWh/yr, about 40,000 MMBtu/yr gas There is an Excel file available that shows site data needed for an IFSAT analysis Site location here is Allentown, PA IFSAT Field Data Forms, partial Form 1, Forms 1-4 in actual Industrial Facilities Systems Assessment Tool (IFSAT) BUILDING DESCRIPTION DATA FORM Building ID: _______________________ Building Type: ________________ Date: ___________________ Prepared by: ___________________ Building Use: __________________________ e.g., metal fabrication Building location (e.g., city state zip ): _____________________________________ circle circle 1.

So this sheet indicates what the estimate will be and allows changes. Enter for: TOTAL SITE, all energy, including process ACTUAL or Electricity Fuel/Steam ESTIMATE kWh/yr Million Btu/yr Use a fuel 4,384,525 42,565 calculator, if available, to derive Electricity Fuel/Steam these values $/yr $/yr $306,917 $510,780 CALCULATED Electricity Fuel/Steam BUILDINGS ENERGY kWh/yr Million Btu/yr based on item 'c' on 2,192,263 21,283 PctFac sheet Electricity Fuel/Steam $/yr $/yr $153,458 $255,390 ADJUST BUILDINGS ENERGY if needed Electricity Fuel/Steam Percent of calculated: 100% 100% kWh/yr Million Btu/yr values here will be used: 2,192,263 21,283 Electricity Fuel/Steam Percent of calculated: 100% 100% $/yr $/yr values here will be used: $153,458 $255,390 for total site applicable to buildings being surveyed Energy Use Adjustment Score Card File Score Card Excel file, version 1.1, has How-to instructions, and some documentation Score Card, Parts 1 3 5, are: 1.
