The poster generation tool helps you to create your own Display® poster. Having entered all the necessary information it works autonomously and immediately makes available a printable poster in pdf format. It uses a calculation tool that initially determines the buildings’ primary energy consumption. Afterwards the instrument calculates the primary energy ratio, the consumption of primary energy per square metre of the gross internal floor area of the building. According its building type, be it educational, administrative or another kind, the building is graded into a classification scheme of six classes: A to G similar to the well known certification scheme used for household appliances.

Concerning CO2 emissions, the tool performs a near identical procedure. The production, transport, and consumption of every unit of whatever fossil energy source emits a certain amount of greenhouse gas, measured in kg of CO2 equivalents. This unit is utilised so as not to forget the emission of other greenhouse gases. To simplify the term “greenhouse gas emissions measured in kg of CO2 equivalents” in the following sections of this users’ guide the term “CO2 emissions” will be used as an equivalent. Similar to the primary energy consumption, the tool calculates the C02 ratio, the CO2 emissions in kg of C02 equivalents per square metre. Again, this ratio serves as a criterion for the grading of the building into a scheme of seven classes.

Water consumption can be treated in an easier way. The water ratio, the consumption of the building in litres per square metre, is used as a performance indicator. Only for swimming pools, the water performance indicator is based on the water consumption per swimmer because it’s more relevant.

Furthermore, the calculation instrument takes into account the building type when grading the building into one of the six classes. It is obvious that a swimming pool will consume more water!
