Safety is the state of being "safe" (from French sauf), the condition of being protected from harm or other non-desirable outcomes. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
There must be ever present in our minds the fundamental truth that in a republic such as ours the only safety is to stand neither for nor against any man because he is rich or because he is poor, because he is engaged in one occupation or another, because he works with his brains or because he works with his hands.
Nearly zero-energy buildings are a major element of European climate policy, and by 2021 every new building has to meet this standard. Hybrid systems that are 100 % renewables will help transform the heating and cooling market, providing improved efficiency and carbon dioxide reductions.
