Definitions
Article 2
In addition to the definitions in Article 2 of Directive 2010/31/EU, the following definitions shall apply noting that for the calculation at macroeconomic level applicable charges and taxes are to be excluded:
1. Global cost means the sum of the present value of the initial investment costs, sum of running costs, and replacement costs (referred to the starting year), as well as disposal costs if applicable. For the calculation at macroeconomic level, an additional cost category costs of greenhouse gas emissions is introduced;
2. Initial investment costs mean all costs incurred up to the point when the building or the building element is delivered to the customer, ready to use. These costs include design, purchase of building elements, connection to suppliers, installation and commissioning processes;
3. Energy costs mean annual costs and fixed and peak charges for energy including national taxes;
4. Operational costs mean all costs linked to the operation of the building including annual costs for insurance, utility charges and other standing charges and taxes;
5. Maintenance costs mean annual costs for measures for preserving and restoring the desired quality of the building or building element. This includes annual costs for inspection, cleaning, adjustments, repair and consumable items;
6. Running costs mean annual maintenance costs, operational costs and energy costs;
7. Disposal costs mean the costs for deconstruction at the end-of-life of a building or building element and include deconstruction, removal of building elements that have not yet come to the end of their lifetime, transport and recycling;
8. Annual cost means the sum of running costs and periodic costs or replacement costs paid in a certain year;
9. Replacement cost means a substitute investment for a building element, according to the estimated economic lifecycle during the calculation period;
10. Cost of greenhouse gas emissions means the monetary value of environmental damage caused by CO2 emissions related to the energy consumption in buildings;
11. Reference building means a hypothetical or real reference building that represents the typical building geometry and systems, typical energy performance for both building envelope and systems, typical functionality and typical cost structure in the Member State and is representative of climatic conditions and geographic location;
12. Discount rate means a definite value for comparison of the value of money at different times expressed in real terms;
13. Discount factor means a multiplicative number used to convert a cash flow occurring at a given point in time to its equivalent value at the starting point. It is derived from the discount rate;
14. Starting year means the year on which any calculation is based and from which the calculation period is determined;
15. Calculation period means the time period considered for the calculation usually expressed in years;
16. Residual value of a building means the sum of the residual values of the building and building elements at the end of the calculation period;
17. Price development means the development over time of prices for energy, products, building systems, services, labour, maintenance and other costs and can be different from the inflation rate;
18. Energy efficiency measure means a change to a building resulting in a reduction of the building’s primary energy need;
19. Package means a set of energy efficiency measures and/or measures based on renewable energy sources applied to a reference building;
20. Variant means the global result and description of a full set of measures/packages applied to a building that can be composed of a combination of measures on the building envelope, passive techniques, measures on building systems and/or measures based on renewable energy sources;
21. Subcategories of buildings means categories of building types that are more disaggregated according to size, age, construction material, use pattern, climatic zone or other criteria than those established in Annex I(5) to Directive 2010/31/EU. It is for such subcategories that reference buildings are generally established;
22. Delivered energy means energy, expressed per energy carrier, supplied to the technical building system through the system boundary, to satisfy the uses taken into account (heating, cooling, ventilation, domestic hot water, lighting, appliances, etc.) or to produce electricity;
23. Energy needed for heating and cooling means heat to be delivered to or extracted from a conditioned space to maintain intended temperature conditions during a given period of time;
24. Exported energy means energy expressed per energy carrier delivered by the technical building system through the system boundary and used outside the system boundary;
25. Conditioned space means space where certain ambient parameters such as temperature, humidity etc. are regulated by technical means such as heating and cooling etc.;
26. Energy from renewable sources means energy from renewable non-fossil sources, namely wind, solar, aerothermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases.
