Energy Savings Through Public-Private Partnerships Act of 2014 - Amends the National Energy Conservation Policy Act (NECPA) to revise requirements for energy savings performance contracts. (These contracts allow federal agencies to work with private contractors on energy efficiency upgrades to federal facilities.)

Directs each federal facility energy manager to provide an explanation regarding life cycle cost-effective measures that have not been implemented as part of the web-based compliance certification system. (Life cycle costs are the total cost of owning, operating, and maintaining a building over its useful life.)

Requires the Department of Energy (DOE) to report to the President and Congress on each agency's energy savings performance contracts and utility energy service contracts, including their investment value and their energy savings.

Expands the kinds of energy conservation measures that may be implemented under the contracts by including those involving energy consuming devices and required support structures.

Prohibits agencies from limiting recognition of operation and maintenance savings associated with energy systems that were modernized or replaced with energy conservation measures and water conservation measures (e.g. lower energy and water bills thanks to energy efficiency and conservation measures).

Authorizes agencies to sell or transfer energy savings and apply the proceeds to fund a contract.

Expands the meaning of energy savings to include: (1) the use, sale, or transfer of energy incentives, rebates, or credits (including renewable energy credits) from federal, state, or local governments or utilities; and (2) any revenue generated from a reduction in energy or water use, more efficient waste recycling, or additional energy generated from more efficient equipment.

Energy Savings Through Public-Private Partnerships Act of 2013 - Amends the National Energy Conservation Policy Act to direct each federal facility energy manager to consider, not later than two years after completion of a comprehensive energy and water evaluation of a federal agency's facilities: (1) implementing any energy- or water-saving or conservation measure that the agency identified in the evaluation that is life cycle cost-effective, and (2) bundling individual measures of varying paybacks together into combined projects. (Under current law, the energy manager is not required to consider such actions.)

Requires the energy manager, as part of the Web-based compliance certification system, to provide reasons for not implementing life cycle cost-effective measures.

Requires each agency to: (1) use the benchmarking systems selected or developed for the agency under the Act to track energy savings realized by the agency through the implementation of energy- or water-saving or conservation measures and submit information regarding such savings for publication on a website of the Department of Energy (DOE), and (2) consider using energy savings performance or utility energy service contracts to implement such measures.

Establishes a goal of entering into energy savings performance contracts or utility energy service contracts equal to $1 billion in each year during the 5-year period beginning on January 1, 2014. Requires each agency to report annually to DOE, and DOE to report to Congress, on progress towards achieving such goal.
