LEED

LEED represents The Leadership in Energy and Environmental Design (LEED) a US Green Building Council (USGBC) Rating System, the nationally accepted benchmark for the design, construction and operation of high performance green buildings. This menu option runs the following simulations.

• LEED NC 2009 - This menu option will calculate the LEED EA Credit 1 points as per the LEED NC 2009 guidelines from the USGBC. EA Credit 1 points are awarded on the percentage difference between the annual energy use of the proposed versus the reference building constructed according to the ASHRAE 90.1 2007 Appendix G standards. The EnergyGauge software automatically calculates these USGBC points and displays a detailed report of the proposed versus reference energy use.
• LEED NC 2009 - EA Credit 1 Report (Adobe not required) - This option does the same calculation as the LEED NC 2009 menu option but displays the output report in a format that is required for the LEED NC 2009 EA Credit 1 PDF. This option does not require Adobe Acrobat Professional to be installed on the client computer. The user has the ability to print this report as a 'Microsoft XPS Document Writer' document and copy all the outputs in to the LEED PDF for submittal. The 'XPS' document can only be opened using Microsoft Internet Explorer.
• LEED NC V4 - EA Credit 1 Report (w/o Online Filing) - Runs the LEED New Construction (NC) v4 simulations that reports the number of credit points in the LEED rating system that a building can earn for improved energy performance. The EnergyGauge software automatically calculates these USGBC points and displays a detailed report of the proposed versus reference energy use.

2005 Commercial Federal Tax Deduction

Provisions in the Energy Policy Act 2005 allow for a tax deduction for energy efficient commercial buildings that reduce annual energy and power consumption by 50% compared to the ASHRAE 2001 Standard 90.1. A special approval code must be provided to use this feature. Once this code is specified by the user under the Help menu, and verified by the software, it need not be entered again till the license is valid. Following are the options available.

* Full Deduction (IRS 2006-52, IRS 2008-40, PATH 2015, $1.80/SF) - The full deduction is applicable if the whole building calculation shows a 50% or greater efficiency than the corresponding reference building for the ASHRAE Standard 90.1. This deduction is a maximum of $1.80 per square foot of the building.

* Partial Lighting (IRS 2008-40, PATH 2015, Interim Rule, up to $0.60/SF) - As per IRS guidelines documented in the notice IRS 2008-40, any commercial building with an improvement of over 25% in the lighting power density as compared to the ASHRAE 90.1 2001 requirements can qualify for a tax deduction. The deduction is scaled appropriately, as per IRS guidelines, in the 25% to 40% savings range and a deduction of $0.60 /SF can be taken for savings over 40%.

* Partial Lighting Deduction (IRS 2006-52, IRS 2008-40, IRS 2012-26 Permanent Rule, PATH 2015, $0.60/SF) - The partial deduction is applicable if the code calculation shows a 50% or greater efficiency of the building lighting than the corresponding reference building lighting for the ASHRAE Standard 90.1. This deduction is a maximum of $0.60 per square foot of the building. 

* Partial System Deduction (IRS 2006-52, IRS 2008-40, IRS 2012-26, PATH 2015, $0.60/SF) - The partial deduction is applicable if the code calculation shows a 50% or greater efficiency of the building mechanical system than the corresponding reference building mechanical system for the ASHRAE Standard 90.1. This deduction is a maximum of $0.60 per square foot of the building.

* Partial Envelope Deduction (IRS 2006-52, IRS 2008-40, IRS 2012-26, PATH 2015, $0.60/SF) - The partial deduction is applicable if the code calculation shows a 50% or greater efficiency of the building envelope than the corresponding reference building envelope for the ASHRAE Standard 90.1.
