Case Study

Significant Cost Savings and Efficiency Improvements for East Haven, CT with Comprehensive Energy and Water Conservation Project

SMI Impact

The replacements yielded savings in water and energy costs of $29,256 per year based on 1,479,965 annual gallons saved across all facilities.

The project resulted in an ROI of 12% with a 10% internal rate of return.

Annual utility savings $16,754

The end use customer experienced 95% reduction in maintenance job tickets

Customer

A ESCO engaged Steam Management, Inc. to design and execute the turnkey installation of multiple ECMs for the Town of East Haven, CT in support of their ESPC. This project included 18 school and municipal buildings.

Conditions

The town and school buildings were outfitted with antiquated equipment resulting in significant waste in both energy, water, and sewer costs. The building custodians were responding to increasing maintenance calls due to wide-spread system failures and occupant discomfort. The metered water consumption for all city buildings was 9,944,660 gallons. The customer needed SMI to design a retrofit that improved user experience, delivered highest quality solutions and yielded savings that met specific ROI criteria.

The challenge of the project was determining the right high-efficiency fixtures in consideration of existing building conditions. SMI utilized our expertise and working knowledge to assess each facility’s needs, conditions and then chose the best option to optimize savings while at the same time not impacting user comfort and building infrastructure limitations.

Equipment issues included:

  • Low efficiency plumbing fixtures in fair to poor condition across all town owned buildings

  • Legacy pneumatic control systems in all schools beyond their useful service life

  • Steam system equipment beyond its useful life throughout all schools

Water Conservation Solutions

SMI project managers spent three (3) weeks surveying each of the facilities. During the investment grade audit (IGA) we complete pre-retrofit measurement and verification (M&V) at FEMP 90/10 level testing across all fixtures to determine the baseline from which to measure design solution effectiveness and savings. The IGA included cataloging every plumbing fixture, identifying, and quantifying water leaks, and determining retrofit options to meet or exceed client expectations.

Based on our IGA, SMI determined 4,678,907 gallons or 47% of metered water consumption was accounted for though the bathroom and kitchen fixtures. SMI was able to design a retrofit program that yielded savings of 1,479,965 gallons annually representing 15% of metered water consumption.

The savings resulting from reduction of heated water yielded an additional 168 MMBtu in energy savings.

The financial impact in the first year was $16,754 in water savings in the first year and $1,005 in fuel savings.

Savings over 10 years was projected to be $192,531.
