Zero Energy House

There are no well-established definitions for this type of building, however, there are several options ^{[2] [3]} :

• Zero net energy buildings that supply the same amount of energy to the grid during the year as they receive from these grids;
• Zero-carbon buildings that do not use energy leading to CO ₂ emissions, or that compensate for fossil fuel energy consumed during the year by producing on-site sufficient energy without CO ₂ emissions;
• Detached buildings with zero energy consumption from a common network ( zero stand-alone buildings ), which do not require connection to any networks other than backup. Such buildings can store energy for use at night or in winter;
• Buildings with a positive energy balance , which supply more energy to the energy supply systems than they use. For a year, these buildings produce more energy than they consume.
• Buildings with negative energy consumption ( zero emission building ), which do not produce carbon monoxide in the process of their operation, construction or production of materials of which they consist. ^[four]

Zero-consumption houses do not use fossil fuels and receive the necessary energy from renewable sources. ^[2] They can be traditional buildings with a large solar collector and solar panel . ^[five]

Most of these houses are built according to the following principles: reducing the required energy, using excess energy, reducing the need for artificial cooling, providing highly efficient climate control systems and other systems, including lighting; providing renewable energy sources of the sun , wind , etc. ^[5]

In Denmark, a house with zero energy consumption can be connected to one or more energy infrastructures: a power grid , a district heating and cooling system, a gas distribution network, a distribution network of biofuel and biomass . ^[6]

Finland

Already built zero-energy houses include: a house for the disabled in Järvenpää (2124 m²), a student dormitory in Kuopio (2124 m²), a single-family house in Mäntyharju (154 m²). In Hyvinkää, a single-family house of 160 m² will be built in 2013. Almost zero consumption houses were erected in Jakobstad (single-family 165 m²) and in Lahti (pensioners' house 16500 m²) ^[7]

Potential issues

• The mismatch between local use and energy production
• Dark cold winters and bright sunny summers
• Off-energy energy conservation
• Integration of the electric network with the district heating system and cooling network
• Finding solutions in relation to the dependencies of heating, cooling, thermal mass , internal power, solar power systems
• Capital solution for the building
• Profitability

Canada

In Canada, the Zero Energy Consumption House Coalition is promoting the idea of zero energy consumption for homebuilding .

The Mortgage and Housing Corporation of Canada funded the EQuilibrium Competition in Sustainable Housing Project ^[8] , combining the efforts of the state and private individuals. In 2006, a competition was held where 12 of the participating projects won 12, the first of which was the ÉcoTerra house in Eastman , Quebec . The cost of its maintenance amounted to 60% lower than a similar standard house. ^[9]
