Zero carbon and zero energy consumption residential buildings have five unique constant systems: constant temperature 25-26℃; constant humidity fresh air dehumidification 50%-55%; constant oxygen fresh air supply; constant quietness 10db; constant cleanliness fresh air purification. Renewable wood + good insulation performance maintenance structure + high-efficiency technical equipment, good external insulation, high-quality transparent maintenance structure, no thermal bridge design, good air tightness, heat recovery fresh air system, and ultimately achieve zero carbon and zero energy consumption.
