Energy Retrofits for Affordable Multifamily Housing July 27, 2010 NHC Webinar Agenda 1. Introduction of CNT and CNT Energy Savers 2. How does it work from the building owners point of view? 3. How does it work from the implementing agencies point of view? 4. Energy Audits and Retrofits 5. Challenges Energy Savers Goal: Reduce operating costs in multi family affordable rental housing in the Chicago metro region • Started in 2008 • Came out of Preservation Compact • Building Owners identified energy costs as a threat • Based on old program • Built on existing partnerships Why an Energy Audit?-Regional Concerns •70% of Chicago’s CO2 comes from buildings, •50% from residential buildings •Midwest imports 90% of its natural gas •Natural gas bills in Midwest four times US average Cost of heating in a 38unit building $40,000 $37,956 $35,000 $30,000 (30% of Operating Budget) $25,000 $20,000 $22,133 $15,000 (23% of Operating Budget) $10,000 $5,000 $0 1998-99 2006-2007 Progress • Combines technical services including energy audits, construction management and financing low-interest revolving loan fund (2.5%) • Targets multi-family building owners in both the private & subsidized markets • Current annual productivity is 3,500 units, in the process of scale-up, 13,000 units of housing audited • Measures the impact of energy efficiency on affordability and housing preservation The Owner’s Point of View Energy Savers Program Eligibility for rental buildings with 5 or more units 1. Building energy assessments (at no cost to owner) 2. Financing options: low-interest loans and some grants 3. Construction oversight and bid package review 4. Annual energy performance reports Energy Audit 1. Analyze fuel bills-Patterns and Energy Use Intensity (EUI): energy usage/square footage 2. Interview occupants/operators 3. Visual inspection 4. Instrumented Analysis: Fig. Natural gas EUI of your building infrared thermography, and other Energy Savers participants thermometer, blower door 136 5. Modeling/common sense 6. Final report w/ recommendations 7.

Monitor Building Performance 26% • Financial Institution – Establish a revolving loan fund – Can combine with grant sources – Can combine with rehab – Can combine with acquisition – Creates a more flexible program • Technical Assistance – Provides information that allows owners to make smart investments – Assures quality installation – Monitors the building post retrofit to assure savings, and encourage additional investment and/or maintenance How do you fund this • Utility energy efficiency programs over the long term • Housing preservation funds • Foundation support for start-up • EECBG opportunities for capitalizing loan fund • Weatherization funds Some Challenges • High cost of transaction as compared to the investment • High Quality Customer Service to reduce owner’s time investment • Subsidize transaction costs • Aligning the goals of cost-effective energy efficiency and housing preservation and rehab Infrared Thermography • Tells you what the surface temperature is: applicable to assess existing insulation, pipes in chases, air leakage in tandem with blower door test, etc. Quantitative value limited. Post retrofit pt. I Cost of Improvements: Air Sealing and Insulation Roof Cavity :$12,400 Replace old converted coal Boiler: $26,000 Savings: $8,890/year (30% reduction in gas bills) Payback 4.5 years Post-retrofit pt. II Outdoor reset control: • Cost: $2,500 • Yearly savings: $9,000…? • Payback: 3 Months… Very old basement door Extremely Variable Field Conditions Contact Information Peter Ludwig Energy Efficiency Programs Manager CNT Energy 2125 W North Avenue, Chicago 60647 Phone 773/269-4048 [email protected]
