Final Customer

Final customer means a natural or legal person who purchases energy for own end use. [Source: EU Directive 2012/27/EU on Energy Efficiency]

Final Energy Use

Final energy consumption covers energy supplied to the final consumer's door for all energy uses. It is the sum of final energy consumption. [Source: Eurostat Concepts and Definitions Database]

Financial Risk

Financial risk includes risks of losses due to price fluctuation of energy (i.e. electricity); interest rate movements, oil price volatility, as well as counter-party risk (the risk that the borrower will not be able to repay the banker). [Source: IEA (2010) Money Matters]

Floor Area

Floor area is a building, architectural and real estate term referring to the amount of area (measured as square feet or square metres) taken up by a building or part of it. The ways of defining floor area depend on what factors of the building should or should not be included, such as external walls, internal walls, corridors, lift shafts, stairs, etc. [Source: Wikipedia]

Frozen Scenario

The frozen efficiency scenario demonstrates where the world would be without policy and market developments - the consequences of inaction. Concretely, this scenario assumes that the energy performance of new and retrofit buildings do not improve as compared to their 2005 levels and retrofit buildings consume around 10% less than standard existing buildings for space heating and cooling, while most of the new buildings have higher levels of energy performance than in the moderate scenario due to lower compliance with buildings codes. Retrofit rates are assumed to be constant throughout the analysed period at the level of 1.4% For water heating it is assumed that the fuel mix and efficiency of water heaters does not change during the analyzed period.

Fuel Poverty

A household is in fuel poverty if it needs to spend more than 10% of its income on fuel to maintain a satisfactory heating regime and all other energy services. [Source: Boardman, 1991]
