In what ways do contemporary buildings conserve energy?

They can use glass, steel, and lots of white surfaces.

They can use computer-assisted designs, laser-cut materials, and 3D printers.

They can use licensed electricians, designers, and plumbers.

They can use smart home technology, LED lighting, and large windows.

They can incorporate green roofs, solar panels, and natural ventilation systems.

They can utilize energy-efficient insulation, HVAC systems, and energy-efficient appliances.

They can implement sustainable materials like recycled steel, bamboo, or recycled glass.

They can use passive design strategies such as orienting the building to maximize natural light and heat gain in winter, or using shading devices to prevent heat gain in summer.

Overall, contemporary buildings use a combination of technology, design strategies, and materials to reduce energy consumption and promote sustainability.
