Zero-house

 
 

A ‘zero’ house is actually a ‘plus’ house. The property also provides enough energy for a car to drive 48,000 kilometers every year.

A zero house most sustainable housing in the Netherlands. Greencalc+ score of 586

A zero house continues as a Living Lab for Smart Grid developments

A zero house, energy-neutral house, balance house, energy balance housing, zero energy house or CO2 neutral house is a house with a normal lifestyle and a high comfort level which generates as much energy as it consumes annually.
A zero house need not be autonomous: it can in summer, for example, deliver energy to the grid and during winter consume from the grid.
To create a zero house one has to first minimize energy use.
This can be achieved by extensive insulation, balanced ventilation and air tightness, a ground source pipe (EWT), triple glazing, a southern orientation and the use of energy efficient devices (passive house concept).
Next one needs an energy efficient heating and hot water supply.
This may be achieved by using, for example, a heat pump, thermal collectors and heat buffers.
The remaining demand for energy generated from renewable energy (solar panels and / or a wind turbine)
The principles for realizing a zero house based on the three-fold energy steps.

The steps to achieving a zero house:
Step 1: Reduce the energy demand (well insulated and airtight construction, heat recovery). Use energy-efficient equipment.
Step 2: Use an efficient system for heating and hot water. For example, use thermal collectors with heat buffers, a heat pump with geothermal energy and energy managers to draw upon proper heat / energy sources. Not forgetting passive energy, such as southern orientation, triple glazing and ground source pipe.
Step 3: Obtain the remaining required energy from renewable energy, such as PV panels or a wind turbine.
