Central objectives to achieve using HVAC technology in buildings are efficient use of energy and a good indoor environment. Big pressure and expectation, nationally as well as internationally is directed towards enhancing energy efficiency. The direction of development seems to be towards passive houses and zero-energy buildings. Besides the quantity of energy, also the quality and origin of energy are of great importance. One goal is to radically increase the portion of on-site produced renewable energies. In this transition the indoor conditions must not be forgotten. Buildings are primarily built for the indoor environment they provide. Good thermal conditions and indoor air quality must be maintained in all situations.The central research areas of the HVAC group are simulation and optimisation of energy use and environmental load of buildings and their HVAC systems, energy technical solutions of zero-energy buildings as well as use of renewable energies in building energy management. The group works also in the fields of indoor environment and building renovation and contributes to development of national regulations and international development.

The basic education in HVAC technology is based on a strong mathematical and physical foundation which gives readiness to develop new things and applications during the work career. Central basic phenomena and principles are learned in thermodynamics, heat transfer and fluid dynamics. Applied studies are built on this foundation, starting from indoor air quality and water management and ending in system design, special questions in air conditioning and measurement of HVAC systems. Post graduate studies are deepening the knowhow of HVAC technology including courses on selected areas and own research work.
