2RW conducted investment grade energy audits for sixteen residential high rises and two multi-family sites, representing more than 3,000 dwelling units. 2RW prepared full design/bid/build documents for the energy improvements at these sites in full compliance with U. S. Department of Housing and Urban Development guidelines. As improvements were installed, 2RW provided construction administration services. At the conclusion of the project, 2RW calculated new resident utility allowances, accounting for the new, efficient building improvements.

Among the utility reduction strategies implemented at the AHA properties as part of the EPC were:

• High efficiency heat pumps
• Lighting improvements
• Energy efficient electric motor replacements
• Replacement plumbing fixtures and shower heads

2RW also designed utility-grade, line-carrier metering systems to enable the AHA to monitor electricity use in each apartment without the need for new electric circuitry. Total improvements to AHA properties were valued at 4.5 million dollars, yielding over $800,000 in reduced annual energy costs.

2RW has provided other services to the AHA over the years, including:

• Sizing and design of chiller replacements.
• Calculation of utility allowances at more than 4,000 residences for the Techwood – Hope VI project.
• Energy audits for AHA high rise properties to comply with HUD regulations.
