Special Considerations
USA tax incentives can make the investment compelling!

New Construction Example with 50% Bonus Depreciation:
A corporation spends $1,000,000 to install a geothermal heat pump system in its new office building. They moved into the building during the 4th quarter of 2010. The corporation is in a 40% tax bracket when state income tax is included.
2012 Tax Credit: $1,000,000 x 10% = $100,000
Depreciable Basis: $1,000,000 – ($100,000 / 2) = $950,000
2012 Tax Credit:$1,000,000 x 10% = $100,000
2012 Bonus Tax Benefit: $950,000 x 50% bonus x 40% tax rate = $190,000
2012 MACRS Tax Benefit: $475,000 x 5% Q4 MACRS x 40% tax rate = $9,500
2012 $475,000 x 38% MACRS x 40% tax rate = $72,200
2013$475,000 x 22.80% MACRS x 40% tax rate = $43,320
2014$475,000 x 13.68% MACRS x 40% tax rate = $25,992
2015$475,000 x 10.94% MACRS x 40% tax rate = $20,786
2016$475,000 x 9.58% MACRS x 40% tax rate = $18,202
Total Tax Savings over 5 Years: $480,000

Subcontractors: Twin City Sheet Metal, Maine Air Balance, Damon Insulation, XL Mechanical

Project Scope

The renovation project consists of a two (2) level interior renovation at the South Portland campus office building comprising of approximately 58,906 SF of area. ABM Mechanical provided design and installation of plumbing and mechanical services for this new office building. Design was based on 150 Tons of cooling load, utilizing a Daikin heat pump system. Heat pumps were located above ceilings, with an open return plenum system which substantially reduced the amount of ductwork to create more flexibility and cost effectiveness. Added Viessmann boilers help to inject heat into the system to maintain adequate loop temperatures when cooling tower reaches it’s lower limit heat recovery threshold.

Special Project Considerations
This project was under a very aggressive 18 week timeframe and ABM was able to completely satisfy the staffing requirements as well as administer subcontractors to comply with the accelerated schedule.

Project Scope
ABM provided the design and installation of the Plumbing & HVAC Systems for the new 86,952 square-foot, four story Hilton Homewood Suites.

The Domestic Water Distribution System is supplied by City Water. Domestic Water enters the building and supplies water to the plumbing fixtures and equipment through a CPVC Piping System. Domestic hot water is heated by two banks of five Natural Gas Fired Instantaneous Water Heaters with added storage of three 119 gallon storage tanks and then distributed to the plumbing fixtures at 120 degree and the Kitchen at 140 Degrees.

The heating is provided by two Natural Gas Fired Viessmann Vitodens 200 Condensing Boilers. The common and pool areas are heated by Air Handling Units (AHU). The corridors at each level are cooled, heated and ventilated by Trane Heat Recovery Units (HRU) located in the attic space. Each Guest Room is equipped with an Amana AHU that supplies outside air, heats and cools the room. The Information Technology (IT) Room is cooled by Fujitsu Mini-split Ductless Cooling Units.

The natural gas piping system was extended to supply the owner furnished indoor fire place and the outdoor cooking grills and fire pit

Special Project Considerations
Some of the special considerations included preserving the building aesthetics, were possible, due to the loft style design. The wood and concrete floors were very thick which made coring holes a challenge.

Project Scope
This project consists of two new additions and renovations to the existing building. ABM Mechanical is responsible for the above and below ground Domestic Water, Sewer and Storm Drain Plumbing and HVAC Systems.
The renovation of the existing building includes new bathrooms, offices, warehouse floor drain improvements, sewer ejection system, Daiken Mini-split Heat Pump Ducted System for heating and cooling with electric radiant heat panels for supplemental heat and an eye wash station.
The new addition includes the addition of bathrooms, office space, loading dock and test kitchen with commercial exhaust hoods and a make-up air unit. Heating and cooling is provided by a Johnson Controls Roof Top Unit (RTU), variable air volume (VAV) boxes with electric reheat coils and associated ductwork.
