Think about renewable energy sources The use of technologies that use renewable energy (solar, biogas, wood) should be considered when designing a building. Convenient is the production of domestic hot water through solar collectors and heat production with high-efficiency boilers and heat pumps, as well as the production of energy electricity with cogeneration systems, photovoltaic panels, and wind generators.
Saving water The rational use of water consists of using devices that reduce water consumption, as well as in the use of rainwater for all technological uses (toilets, washing, washing machines, irrigation, etc.).
Avoiding health risks to building occupants also arise from the use of certain building materials that emit large amounts of solvents, dust, fibers, and other toxic agents during production and processing, which are harmful even after construction for a long time, leading to indoor pollution and causing discomfort and illness.
Use materials obtained from regenerable and local raw materials The use of materials obtained from regenerable raw materials (or abundantly available, such as FSC-certified wood, which ensures sustainable and responsible forest management) and with processes that require little energy significantly reduce environmental impacts. The use of local materials makes transportation short, and reduces fuel consumption and environmental pollution.
Use recyclable materials The use of recyclable materials prolongs the permanence of materials in ecological and economic cycles, consequently reducing the consumption of raw materials and the amount of waste.
Manage waste ecologically In order to manage waste from demolition and renovation ecologically, one must decrease the quantity and variety, and collect it in a way that facilitates recovery, recycling, or disposal by sorting it into categories.
