Good indoor air equals creative minds
Indoor climate quality and satisfaction have a direct link with productivity. As 90% of the annual costs of a typical office building are related to personnel working in the building, even a modest 1–3% drop in productivity is economically significant. Increased productivity results from improved work performance and better health, which reduce the amount of sick leave. Keeping conditions at the designed levels regardless of usage fluctuations or layout changes is of great importance to user satisfaction.

Life cycle effects
Economical life cycle costs are a result of multiple elements functioning to the same end: reduced running and energy costs in all usage situations, a simplified maintenance model and in-built flexibility for layout and usage changes. A well‑designed indoor climate solution provides competitive life cycle costs in addition to creating good, productive indoor climate conditions. 
 
A sustainable indoor climate
A focus on energy savings and use of renewable energy sources has been identified as a major factor in improving care for the environment and reducing carbon emissions in the construction industry. Buildings are the largest end user of energy in the EU, accounting for 40% of total consumption. The building sector holds the largest energy savings potential, with a 22% reduction possible by 2010. The energy‑efficiency of buildings is greatly affected by air conditioning and ventilation systems. Buildings’ energy consumption depends on the system designed and its maintenance. Even if one considers only energy consumption and the resulting CO2 emissions, energy-intensive air conditioning systems have a large environmental impact compared to energy-efficient systems.
