“…In view of this, there is a special need to use low-carbon building materials [20,21] based on using digital technologies in construction [22,23]. Alaux et al examined the impact of using energy efficiency and bioenergy technologies in construction at the level of GHG emissions [24]. In the context of the correlation of energy and construction of lowcarbon materials transition, the integration of climate management in green energy supply change [25] and diversification of renewable energy sources need deepening intersectoral cooperation [26].…”

The sustainable implementation of resources and the transition to low-carbon construction is on the world’s daily agenda. This paper describes the development of criteria for the efficient management of material resources in low-carbon construction. Net income, gross profit, balance sheets, and equity are proposed as indicators that serve as criteria for assessing the efficient use of resources. Nonlinear regression models were the methodological basis for the establishment of cause-and-effect relationships of the volume of construction of transport structures. It was established that since construction companies do not purchase materials for storage, the cost of materials for use in low-carbon technological construction work is directly proportional to the cost of construction. The volume of production in the construction industry is determined by construction costs. More efficient use of low-carbon materials reduces cost and construction waste. In this paper, we have established the relationship between the indicator of efficiency for the functioning of the construction enterprises in Ukraine and the use of low-carbon materials for the construction of transport structures. The practical value of the obtained results for low-carbon construction management lies in proving the relationship between the performance indicators of the construction enterprise (net profit, gross profit, output volume, balance sheets, and equity capital) and the use of low-carbon material resources. Our results form the basis for future research into the use of a cost-based model for low-carbon economy transition in municipalities and regions.

“…In addition, due to their particularly long lifespan, the choices made for buildings constructed today largely determine the level of their long-term environmental impacts (Frischknecht et al 2019). This is why the scientific literature has put remarkable efforts in identifying emission reduction strategies for buildings, whether targeting the operational emissions, i.e., emissions coming from the functioning of the building (Hoxha and Jusselme 2017;Lasvaux et al 2017;Drouilles et al 2019), or the embodied emissions, i.e., emissions related to the materials, transport, construction, and end-of-life (Alig et al 2020;Zhong et al 2021;Alaux et al 2023). Trade-offs between embodied and operational emissions in order to improve the life cycle performance of buildings have also been highlighted in multiple studies (Mirabella et al 2018;Lützkendorf and Balouktsi 2016).…”

Purpose The greenhouse gas (GHG) emissions caused by the construction industry account for an enormous share of total global CO2 emissions. The numerous construction activities therefore continue to reduce the remaining carbon budget. One lever for the reduction of these GHG emissions lies in the procurement process of buildings. For this reason, a process model was developed that takes embodied and operational emissions into account in the tendering and awarding phase of buildings. Methods To validate the developed theoretical framework, environmental life cycle costing (eLCC) was conducted on a single-family house case study, taking into account external cost caused by GHG emissions. Various shadow prices were defined for the calculation of external cost to identify changes in award decisions. We further investigated a results-based climate finance (RBCF) instrument, i.e., the GHG emission bonus/malus, to demonstrate an approach for calculating Paris-compatible cost (PCC) scenarios. Results We show that an award decision based on life cycle costing (LCC) leads to a 12% reduction in GHG emissions. A further reduction in GHG emissions can be achieved by awarding contracts based on eLCC. However, the required shadow prices within the eLCC awards to influence the award decision are quite high. With the development of the LCA-based bonus/malus system, PCC scenarios can be determined at sufficient shadow prices, and further GHG emission reductions can be achieved. Conclusions Since the implementation of LCA and LCC in the tendering and awarding process is currently not mandatory, in this context, the next step towards Paris-compatible buildings must first be taken by the awarding authorities as well as the policy-makers. However, the application of the LCA-based bonus/malus system and thus the awarding of contracts according to PCC scenarios show the enormous GHG emissions reduction potential and thus represent an innovative and sustainable framework for an adapted procurement process.

“…Finally, at the building level, the increased use of bio-based materials is included: wood as a structural material and cellulose for insulation. The detailed influence of these different strategies at the material, building and provincial level can be found in previous contributions [9,19]. For the diffusion of these technologies, plausible estimations are created, based on previous literature [20].…”

“…Various countries have already created detailed models of their building stock [7]. Similarly, first developments in the building material stock of specific Austrian cities or regions have been conducted [8,9]. Yet, most of these studies focus on the development of the building stock itself, without necessarily linking it to LCA and without specifically considering public buildings.…”

Responsible for 37% of global greenhouse gas (GHG) emissions, the construction and operation of buildings involves substantial potential to mitigate climate change. Although they represent only a small part of the building stock, publicly-owned buildings can lead by example and stimulate emission reductions through public procurement processes that are aligned with existing climate goals. In this paper, possible GHG emission reduction pathways for public office buildings in Austria are explored. A building stock model for Austria’s publicly-owned office buildings is developed, which projects operational and embodied GHG emissions from new construction, renovation and demolition until 2050. Findings show that phasing out fossil fuel use in building operations by 2050 enables GHG emission pathways that are compatible with the Carbon Law but still exceed Austria’s available carbon budget for public office buildings. A higher renovation rate can facilitate the fossil fuel phase-out by reducing energy demand. Embodied GHG emissions are becoming increasingly important and the main source of GHG emissions when phasing out fossil fuels in space heating. More research and policies are therefore needed to accelerate reductions of embodied GHG emissions towards net zero.
