A RT 2020 house is no more than a passive house in more powerful. Indeed, a passive house is a house that produces as much energy as it consumes. A RT 2020 house must exceed its energy needs through the production of renewable energies. The surplus energy can be returned to the public grid.
A positive house, or positive energy building, is the concept which RT 2020 aligns to. These buildings consume less energy than they produce, due to technical solutions (for roofs, walls, windows or verands) allowing the accumulation of heat and the production of electricity. The need to eliminate thermal bridges (often weakly insulated and usually between two walls such as a roof and wall) by means of insulation from the outside, for example, or where there are detached facades of structures.
The main deifference between the RT 2012 and the RT 2020 is the energy expenditure limits. While the RT 2012 corresponds to a ceiling of 50 kWh/m²/year, namely the average value of the low energy building lable, the RT 2020 requires the production of energy to be greater than consumption. The expenditure must therefore be less than 0 kWh/m²/year.
