Active technologies (options) involve the use of mechanical and electrical systems for the conditioning and running of a building. Active options should never be a substitute for good design. They should only be implemented when passive options alone are not sufficient to meet the minimum requirements. Best available technologies with high efficiency values should be used and be powered as far as possible by renewable energy.
Energy-efficient buildings can be achieved through a holistic design with energy-efficient technologies and intelligent building management. This holistic design follows the Strategic Approach paradigm of first implementing load-reducing “Passive Options” for building design, followed by energy-efficient “Active Options” for thermal conditioning and ventilation as needed and then fine-tuning building operation through “User Behaviour and Energy Management”.
