Aleda E. Lutz – Building 6
Saginaw, MI

The Veterans Administration constructed Building 6 on the Aleda E. Lutz campus in Saginaw, Michigan to achieve a Leadership in Engineering and Environmental Design (LEED) rating of Silver.  The building included energy efficient lighting (light emitting diode & compact fluorescent, occupancy sensors), heating ventilation and air conditioning (connection to central heating plant 12 EER roof top cooling, energy management system) and insulation (3” isoboard, R-21) walls and roof. Total square feet – 7,318

Design-Aire Engineering (DAE) provide building simulation to determine if modifications to the Aleda E. Lutz Veterans Administration Medical Center reduced energy costs sufficient to qualify for Leadership in Energy and Environmental Design (LEED) accreditation

Building 6

DAE determined renovations to the lighting, heating, air-conditioning and building envelope systems reduced energy consumption and cost by 24% and thereby qualify for 9 points toward LEED Silver accreditation.

Clark Pleasant School Corporation – Whiteland High School

DAE identified, implemented, and evaluated energy conservation measures for Whiteland High School.  Energy efficient and environmentally friendly materials were incorporated in their facility addition for LEED certification. Total project cost was $147,900.

Jasper County Public Library

DAE identified, implemented, and evaluated problems with energy conservation measures to upgrade the client’s lighting, heating, ventilation, and air-conditioning systems.  Total project cost was $88,000.

Indiana Government Center

DAE assisted client in identifying energy conservation measures, which will result in a 21% reduction in energy costs. On-site chilled water generation at IGC-South was recommended, saving over $97,000/yr in energy costs at no additional cost. Total project cost was $4,950,000.

Turkey Run State Park

DAE assisted our client in identifying energy conservation and environmental protection ideas for Leadership in Energy and Environmental Design (LEED).  The certification included heating, ventilation, and air conditioning, lighting, water conservation, and alternative fuels. Total project cost was $250,000.

Blackford County High School

An energy audit conducted at this 158,000 square foot high school focused on 6 Energy Conservation Measures (ECM).  Among those studied were VAV reheat system conversion, exhaust fan duty cycling, door vestibules, lighting reduction, swimming pool heat reclaim climate control system, and replacement of 450-ton chiller. Resulting implementation of the recommended ECMs reduced the electric bill for this all electric school over 19%, or $55,000 per year. 

As a Certified Energy Auditor for the State of Indiana, DAE successfully petitioned the Department of Energy for a matching grant for Blackford County High School.  Following the grant award, DAE helped the high school with several additional mechanical upgrade projects, such as chilled water system upgrades and VAV revisions to the HVAC.

North Harrison Community School Corporation

DAE’s audit of 4 schools for North Harrison School Corporation recommended savings opportunities that totaled more than $26,000/year, with average payback between 2 to 6 years. Energy savings measures included lighting upgrade, occupancy sensor control of lights and vending machines, boiler burner retrofit, and CO2sensor control of outside air.

South Spencer Schools

DAE recommended energy saving measures for the high school which totaled $47,341/year with an average payback of 6.8 years. Measures recommended include motion-detection control of vending machine power, VAV conversion of existing constant volume reheat, and heat reclaim climate control system for the swimming pool.

Guide Corporation Energy Audit

Energy audit of 1.3 million square foot manufacturing facility resulting in 40% ($1.4 million) operating cost reduction with 4 month payback.  Savings resulted from revisions to heating systems, replacement of existing lighting to high efficiency lamps and electronic ballasts with motion detection control, and modulation of plant compressed air system to better match actual load.

Atlas Foundry

The energy audit for this 90,000 square foot foundry, constructed in 1893, identified several energy conservation opportunities.  These included variable frequency drives, makeup air replacement, plant-wide demand control, melt furnace heat reclaim, and air compressor heat reclaim.  The implementation of these modifications resulted in a 1.7 year payback (59% ROI).  The annual energy cost was reduced from $934,780 to $841,873, a savings of $92,581 or approximately 10%.
