2 Potential Intrinsic

Predicted performance versus intrinsic value after limited investments.

3 Actual

Assessed based on current occupants and operations.

4 Potential Actual

Potential for evolution based on behavioural improvements and operational adjustments.

Deliverable

One chart for each indicator
of the four levels:

6 Objective and Tangible Indicators

Energy

Quantitative indicator expressed in kWh/m�/year of final energy use
Represents the energy needs of a building calculated with dynamic and calibrated modelling.

Transport

Qualitative indicator on a scale of 1 to 9
Mainly based on access to public transport and provisions within the vicinity of the building.

Carbon

Quantitative indicator expressed in kg CO2 eq/m�
Represents the level of greenhouse gas emissions resulting from building energy use.

Water

Quantitative indicator expressed in cubic meters /m� per year
Represents a property�s water consumption.

Well being

Qualitative indicator on a scale of 1 to 9
Based on the quality of a property�s indoor environment
(air quality, noise, natural light, comfort).

Waste

Qualitative indicator on a scale of 1 to 9
Based on a building�s capacity for waste sorting and related operational practices.
