Passive design is a design that does not require mechanical heating or cooling. Instead, they use nature for cooling and heating. Studio Negri was recently awarded certification in the design of passive houses, from the Passivhaus Institut, Darmstadt, Germany.
Advantages of Passive Houses
Increases natural comfort
Decreases greenhouse gas emissions from heating, cooling, mechanical ventilation and lighting.
Passive Houses incorporate very high standards of insulation. This reduces the amount of heat lost through the building fabric to the lowest possible levels. When achieving these very high standards of insulation the purpose provided heating requirement, even on the coldest days, is reduced to a minimum and hence it is possible to adequately heat the dwelling by just preheating the fresh air entering the rooms.
