Improved indoor air quality helps to reduce the health and safety risks to occupants from Sick Building Syndrome (SBS) and Legionnaire’s Disease (Shiers, 2000). There are estimates, that improved heating, ventilating, and air conditioning (HVAC) systems, which limit the spread of contaminants and pathogens, could reduce respiratory illnesses by 9%–20%. Better indoor air quality can also reduce asthma attacks and allergies. Health and comfort are becoming increasingly important with the growing concern about staff welfare. Through sustainability, companies can improve their competitive advantage in the recruitment and retention of talent. 36 Bioclimatic Tools in Architecture Centre Jean-Marie Tjibaou at New Caledonia Bioclimatic Tools in Architecture Renzo Piano‘s answer to local needs Bioclimatic Tools in Architecture Wind grids Bioclimatic Tools in Architecture „The Wind Gap“ Bioclimatic Tools in Architecture Ökologische Qualität Kriterien 01-05, 10,11 – Ökobilanzierung ZIEL © S.
