The need to implement sustainable development (SD) in the construction industry has given birth to the green building (GB) movement. GB is a promising construction approach through which the construction industry contributes to SD. However, the adoption of GB has been hampered in many parts of the world by numerous barriers. To date, no attention has been paid to the need to review existing knowledge of barriers affecting GB adoption. This paper presents a systematic review of literature on barriers to GB adoption published in academic journals.

Addressing energy use in the built environment is just one aspect of the carbon reduction challenge, according to The Footprint Company chief executive Dr Caroline Noller. Addressing the embodied carbon in building materials is also vital.

Dr Noller told The Fifth Estate international data showed that more than 50 per cent of global carbon emissions ended up in a building or infrastructure material of some kind.

Covering roofs and walls of buildings with vegetation is a good way of reducing greenhouse gas emissions. And these green roofs and walls make cities look nicer. Toronto’s central business district adopted a policy of establishing green roofs on around half of all city buildings in 2009. Research shows this could reduce maximum city temperatures by up to 5℃.

Building energy efficiency has been identified as a cost-effective opportunity to reduce energy consumption and greenhouse gas emissions and a variety of policies are being implemented to harvest this efficiency potential. However, there are growing concerns about a gap between predicted or expected energy consumption levels in buildings and the actual measured energy consumption in operation, both at an individual building level as well as in the building sector as a whole.

The purpose of this study was to complete a literature review of the economic assessment of the costs, benefits and methods for the construction of houses that are designed and built to standards that exceed the minimum requirements as defined by the Building Code. The scope included international and local assessments, academic and grey literature and industry material such as facts sheets. Key findings Many studies focused on energy savings as the sole benefit.
