Energy upgrading of buildings in Greece with eco-materials: An investigation of public awareness

The environmental impact of the construction sector is significant making it necessary to adopt sustainable solutions for energy upgrades of buildings. Furthermore, the use of advanced eco-materials to improve the energy efficiency of buildings has been shown to provide better energy conserving results than conventional upgrading materials, contributing directly to the improvement of the comfort level of building occupants. This study investigates the public view in Greece regarding energy upgrades of buildings using eco-materials. A mixed methods research approach was employed based on a questionnaire survey investigating the public’s knowledge of the need, the benefits of using eco-materials and the motivation required to renovate the buildings they live and work in to a higher energy efficient standard. Although technologies in advanced eco-materials have increased, the survey showed that, regardless of the existence of government subsidies, the general public in Greece is unaware of the importance of and benefits from upgrading their buildings with eco-materials. As a result, there is an urgent need to embark on more rigorous environmental awareness campaigns to support local authorities in implementing sustainability policies, like the use of eco-materials for the energy efficiency improvement of buildings, to create sustainable and healthy cities.
