Implementation conditions for energy saving technologies and practices in office buildings: Part 2. Double glazing windows, heating and air-conditioning

This paper provides a review of the energy saving policies and technologies on double glazing windows, central heating and air conditioning in office buildings. After which results of a face to face survey of 685 companies’ managers are presented, which give insights into the facts that have influenced them to invest in the installation of double glazing windows, installation of thermostatic regulators, inverter air-conditioning technologies and on proper maintenance and filter cleaning of the air-conditioning units. Finally, their willingness to install such technologies after a technico-economic information session is elicited. The results show that among factors that make managers have a more energy saving profile are ownership, awareness status, recent establishment of the company and companies dealing with trade. Among factors that influence willingness to undertake specific energy efficient measures for heating and cooling appear to be ownership, recently established companies, companies dealing with services, companies with a high number of personnel, and companies with high ratios of electricity bill per annual turnover.
