General assumptions

2.1.1 Calculation interest (%)

2.1.2 a Depreciation period installation (year)

2.1.2 Depreciation period fixture (year)

2.1.3 Discount factor (luminaries)

2.2.1 Energy price (EUR/kWh)

2.2.2 Effect price (EUR/kW)

2.3.1 Share that contributes to space heating (%)

2.3.2 Proportion of peak load effect (%)

2.4.1 % of installation to include Daylight harvesting when using lighting control

<>Constant Light Solution (CLS)

2.3.3 Hours of use per year light installation

Application

* The luminaire prices and installation price must be checked with the installer vs the end user

* The LMS calculation is in accordance with EN 15193 and indicates a saving of 40% on the presence sensor. This is indicated as reduced usage time on lighting systems (2.3.4). This is considered a conservative assumption.

* Daylight saving is calculated at 24% of the part of the facility that has daylight saving. This is indicated as reduced power requirement 2.4.11
