‘total useful floor area’ means the floor area of a building or part of a building, where energy is used to condition the indoor climate.

Where a Member State requires that the obligation to renovate each year 3 % of the total floor area extends to floor area owned and occupied by administrative departments at a level below central government, the 3 % rate shall be calculated on the total floor area of buildings with a total useful floor area over 500 m and, as of 9 July 2015, over 250 m owned and occupied by central government and by these administrative departments of the Member State concerned that, on 1 January of each year, do not meet the national minimum energy performance requirements set in application of Article 4 of Directive 2010/31/EU.

Member States should be able to choose to define a ‘major renovation’ either in terms of a percentage of the surface of the building envelope or in terms of the value of the building.

This could necessitate adjustments in terms of CF-18s, tanker aircraft, the navy's major surface and subsurface combatants, shipborne ground-to-air-based radars, and data fusion arrangements.

Maritime Forces Atlantic, for example, has 5,230 Canadian Forces personnel, of whom about 2,625 serve on surface ships.

As we look to the future, the next new surface combatant in the dollars of those days will be substantially more than $11 or $12 billion.
