Inside the buildings we spend most of our time, therefore buildings have great impact on many aspects of our life, especially on our health. Winston Churchill once said: "We shape our buildings; thereafter they shape us". When designing, we focus mainly on architecture, economy and ecology, omitting the most impartant purpose of sustainability: health. Even 30% of new or refurbished buildings are considered sick buildings, where diseases like SBS (Sick Building Syndrome) ar Legionnaire's disease can affect users. This might be the consequence of i.a. inadequate HVAC design, microbial contamination, lack of natural light or bad acoustic. And the totality of factors in indoor environments that influence human health, well-being and productivity of people who work in those spaces is called "buildingomics". lt's identification is now the most important part of green building certification systems like LEED or BREEAM. These certification process concentrates more and more on non-technical aspects like productivity, well-being, satisfaction and creating non-stress environment. However fully dedicated to the subject of health is Well Building Standard, which enables the analysis of building's impact on human health.
