“…Guggemos et al [8] proposed that the embodied GHG emissions of permanent building materials should be omitted in this calculation because they belong to an independent part of the materials manufacturing phase during the overall life cycle assessment (LCA). Nevertheless, construction processes and techniques used in semi-prefabrication are different from those in conventional construction methods.…”

“…Numerous studies primarily concentrated on developing advanced technologies, policies, and measures to cut down GHG emissions in the operation stage [4][5][6][7] rather than in the construction stage. Guggemos et al [8] pointed out that the environmental impact and GHG emissions from the construction phase cannot be ignored, even if this phase only accounts for 0.4% to 12% of the overwhelming impact from the operation stage. GHG emissions in construction is a small share of the entire life cycle at present, but the 80% to 90% of the life cycle of GHG emissions that occur during the operation has declined dramatically over time due to existing substantial energy saving codes or other policies, and thus, the relative contribution of construction stage emissions and impacts becomes more dominant and significant.…”

“…Several studies have focused on the environmental impacts and GHG emissions in the construction phase [8][9][10][11]. The literature has two common characteristics: (1) they are associated with conventional cast in situ construction methods, and (2) they concentrate on the scenario selection of building materials or structural systems to reduce GHG emissions.…”

“…Guggemos et al [8] emphasized the importance of the construction phase and designed a Construction Environment Decision-Support Tool. The tool helps decision-makers and designers optimize design, selection of materials, and construction scenarios according to estimated energy use, emissions, and waste generation rates in the construction phase.…”

Greenhouse gas (GHG) emissions in the construction stage will be more relatively significant over time.Different construction methods influence GHG emissions in the construction phase. This study investigates the differences of GHG emissions between prefabrication and conventional construction methods. This study sets a calculation boundary and five emission sources for the semi-prefabricated construction process: embodied emissions of building materials, transportation of building materials, transportation of construction waste and soil, transportation of prefabricated components, operation of equipment, and construction techniques. A quantitative model is then established using a process-based method. A semi-prefabrication project and a conventional construction project in China are employed for preliminary examination of the differences in GHG emissions. Results show that the semi-prefabrication method produces less GHG emissions per square meter compared with the conventional construction, with the former producing 336 kg/m 2 and the latter generating 368 kg/m 2 . The largest proportion of total GHG emissions comes from the embodied emissions of building materials, accounting for approximately 85%. Four elements that positively contribute to reduced emissions are the embodied GHG emissions of building materials, transportation of building materials, resource consumption of equipment and techniques, and transportation of waste and soil, accounting for 86.5%, 18.3%, 10.3%, and 0.2%, respectively, of reduced emissions; one a negative effect on reduced emissions is the transportation of prefabricated components, which offsets 15.3% of the total emissions reduction. Thus, adopting prefabricated construction methods contribute to significant environmental benefits on GHG emissions in this initial study.

“…Varnäs et al (2009) claim that environmental criteria in tender evaluation are less common and seldom affect the award decisions. Guggemos and Horvath (2006) propose the Construction Environmental Decision-Support Tool to allow designers and practitioners to quantify energy use, emissions and waste generation due to the construction phase of commercial buildings. Palmujoki et al (2010) highlight that although 'green' criteria are often included in calls for tenders, it is not necessarily that they are included in the final contract clauses.…”

Optimal bid model for construction contracts

Construction clients are increasingly calling for bids that require contractors to submit both bid price and highlight sustainability attributes. Contractors are faced with the problem of deciding which combination of bid price and sustainability attributes to submit. An important consideration is the cost of sustainability attributes to the client. This varies between contracts and types of projects. This paper proposes the use of a sustainability unit value which the client can use as a basis for determining the contractor's total combined bid. This kind of procurement method is traditionally known as the A+B method. To illustrate the mechanism of price-sustainability attribute bi-parameter procurement, a total combined ISO-map is developed. The contractor's price-sustainability performance curve is then incorporated into the map to determine the contractor's optimal bid parameters: tender price and sustainability performance. A mathematical optimisation bid model is developed for calculating the optimal bid parameters.

The construction industry provides infrastructure and structures to society by consuming a substantial quantity of non‐renewable energy, which results in significant carbon dioxide emissions. Carbon dioxide (CO2) could pose a serious danger to the economy of any nation if proper measures are not put in place with the country being one of the leading producers and end‐users of fossil fuels in the world. This article seeks to evaluate the barriers to the adoption of carbon trading practices (CTP) in the construction sector with the view to ensuring low carbon usage. The article adopted quantitative approach with data obtained using questionnaire. Mean Item Score (MIS), standard deviation (SD), factor analysis and Kruskal–Wallis test was carried out in relation to the research questions. The study showed that the most significant barriers to the adoption of carbon trading are difficulties in obtaining finance, attitude to environmental sustainability and climate change, lack of cost‐effective abatement options and methods, lack of awareness of carbon market opportunties and risk in changes in the rules governing participation and credit among others. This study provides valuable insights into barriers of CTP in construction and will help stakeholders concerned with building energy performance to develop a functional framework for energy analysis in buildings to prepare possible risk analysis from the onset of project design spanning through completion.
