Meyer Najem – Headquarters

Meyer Najem Headquarters – EPACT

DAE certified Meyer Najem is eligible for a $75,571 EPACT tax deduction for the energy efficient interior lighting, HVAC and building envelope systems at their new 41,984 square foot facility.

Meyer Najem new headquarters uses light emitting diode (LED) light fixtures with occupancy sensors, roof-top units (12 EER) with variable air volume (VAV) boxes, 2″ wall and 3″ roof board insulation.

DAE provided an all documents (consultants letter of project overview, certification, Internal Revenue Service (IRS) documentation, building simulation and lighting specifications necessary for Meyer Najem to claim the EPACT tax deduction.

The EPACT tax deduction reduced Meyer Najem’s project cost and the energy efficiency improvements reduced their energy and maintenance costs.

Daviess County – Cross Dock Warehouse

Cross Dock Warehouse – Daviess County

DAE designed lighting, heating, ventilation and air-conditioning (HVAC) systems for Daviess County warehouse facility in Washington, Indiana.

Daviess County wanted to install energy efficient lighting, HVAC and building envelope systems at their new maintenance and warehouse facility. Daviess County wanted a lighting level of at least 35 foot-candles and uniform space (heating) temperatures.

DAE recommended (74) T5 fluorescent (6 lamp) lighting and (1) 1,250 MBtuh air rotation unit to illuminate and provide space heating. DAE design will provide light levels of 40 foot-candles with a +/-2 F temperature difference between floor and ceiling. ARU use high velocity fans to circulate stratified air at the ceiling back to the floor and thereby recovering heat from lighting. The air rotation unit fans will also provide free cooling in the spring and fall.

Daviess County requested DAE provided construction management during equipment installation.

Daviess County’s new HVAC system will reduce heating costs by 15% and reduce cooling costs by 10% compared to standard efficiency air-conditioning units.

Fire Station No. 4 (New Construction)

Kokomo, Indiana

Kokomo Fire Station No. 4

The City of Kokomo has provided fire protection since 1867 and has grown to more than 100 fire fighters staffing six stations. The City of Kokomo needed an additional fire station located south and west of city limits. The City of Kokomo wanted to build a fire station with low operation costs without sacrificing comfort to the fire fighters who occupy the station continuously.

The new facility was to house (6) dormitory rooms, with the ability to grow to (8); and (2) apparatus bays.

DAE recommended a heating, ventilation and air-conditioning system with high efficiency, T5 and compact fluorescent lighting, HVAC (95% AFUE, 16 SEER) units, radiant tube heaters (garage 90% AFUE) and condensing (90% AFUE) gas hot water heater. The facility also includes high efficiency light emitting diode (LED) site lighting and water saving toilets and urinals.

It costs the city about $1 million a year to staff one fire engine 24 hours a day, 365 days a year. The new Fire Station #4 will use 25% less energy and cost only 6% more than a fire station built to Indiana Building Code.

Building 6 – Energy Model

Aleda E. Lutz VA Medical Center

Saginaw, Michigan

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.
