Passive energy-saving methods for near-zero energy buildings include reasonable layout of building orientation, sunshade settings, thermal insulation technology and natural ventilation building opening design.
Near-zero energy buildings utilize passive design strategies to minimize energy consumption. Reasonable building orientation can maximize the use of natural light and ventilation and reduce the need for artificial lighting and mechanical ventilation. Shading facilities such as blinds and visors can help reduce indoor temperature rise in summer and reduce air conditioning energy consumption. Use high-efficiency thermal insulation technology, such as insulation materials and insulation layers, to reduce indoor and outdoor heat exchange and reduce heating and cooling energy consumption. Reasonable design of building openings, such as window location and size, promotes natural ventilation, improves indoor air quality, and reduces mechanical ventilation energy consumption.
