Life cycle cost analysis (LCCA) of Stirling-cycle-based heat pumps vs. conventional boilers

Khan, Umara (author), Zevenhoven, Ron (author), Stougie, L. (author), Tveit, Tor Martin (author)

Heat pumps (HPs) which use low temperature (waste) heat and renewable energy sources to provide high temperature heat are widely regarded as a critical technology for reducing carbon dioxide emissions in the industrial sector. The HighLift technology considered here can provide high temperature output heat up to around 200 °C. This article...

The technical or biological loop? Economic and environmental performance of circular building components

Jansen, B. (author), van Stijn, A. (author), Eberhardt, Leonora Charlotte Malabi (author), van Bortel, G.A. (author), Gruis, V.H. (author)

The construction sector can become more sustainable by applying the Circular Economy concept, which distinguishes two main pathways: substituting materials for biological materials, or optimizing the use or reuse of technical materials. Practitioners sometimes choose one pathway over the other, but knowledge of which of these pathways yields...

A circular economy life cycle costing model (CE-LCC) for building components

Jansen, B. (author), van Stijn, A. (author), Gruis, V.H. (author), van Bortel, G.A. (author)

The building industry is responsible for the highest resource use, amount of waste and emissions of all industries. The principles of the Circular Economy (CE) could offer an approach to create a more sustainable built environment. For a transition towards a circular built environment, a comprehensive assessment method is needed to support...

Assessing the life-cycle sustainability of algae and bacteria-based wastewater treatment systems: High-rate algae pond and sequencing batch reactor

Kohlheb, Norbert (author), van Afferden, Manfred (author), Lara, Enrique (author), Arbib, Zouhayr (author), Conthe Calvo, M. (author), Poitzsch, Christoph (author), Marquardt, Thomas (author), Becker, Mi Yong (author)

High Rate Algae Ponds (HRAPs) are a promising technology for the treatment of municipal wastewater in locations with sufficient space and solar radiation. Algae-based processes do not require aeration, and thus have the potential to be less energy-intensive than activated sludge processes. We used a combination of LCA and LCCA analysis to...

Salt marshes for flood risk reduction: Quantifying long-term effectiveness and life-cycle costs

Vuik, V. (author), Borsje, Bas W. (author), Willemsen, Pim W.J.M. (author), Jonkman, Sebastiaan N. (author)

Flood risks are increasing worldwide due to climate change and ongoing economic and demographic development in coastal areas. Salt marshes can function as vegetated foreshores that reduce wave loads on coastal structures such as dikes and dams, thereby mitigating current and future flood risk. This paper aims to quantify long-term (100 years)...

Zhang, Chunbo (author), Hu, Mingming (author), Dong, L. (author), Gebremariam, A.T. (author), Mirand-Xicotencatl, Brenda (author), Di Maio, F. (author), Tukker, Arnold (author)

The increasing volume of Construction and demolition waste (CDW) associated with economic growth is posing challenges to the sustainable management of the built environment. The largest fraction of all the CDW generated in the member states of the European Union (EU) is End-of-life (EOL) concrete. The most widely applied method for EOL concrete...

Reliability-based life cycle costing analysis for embedded rails in level crossings

Shang, Y. (author), van den Boomen, M. (author), de Man, Amy (author), Wolfert, A.R.M. (author)

Reliability-based life cycle costing analysis (LCCA) supports optimized decisions on capital and operational expenditures for engineering asset management. In addition, it allows investigation of the impact of maintenance decisions on designing the service life of assets. The application of reliability-based LCCA in railway practice is...

A life cycle costing approach for discounting in age and interval replacement optimisation models for civil infrastructure assets

van den Boomen, M. (author), Schoenmaker, R. (author), Wolfert, A.R.M. (author)

Civil infrastructure assets, such as roads, locks, bridges, treatment plants and storm surge barriers, are often characterised by long service lives and corresponding technical life cycles. When life cycles are long, the time value of money plays a role in asset management decision-making on capital investments and operation and maintenance...

Preliminary study of life cycle cost of preventive measures and repair options for corrosion in concrete infrastructurecorrosion in concrete infrastructure

Polder, R.B. (author), Pan, Yifan (author), Courage, Wim (author), Peelen, Willy H A (author)

Maintenance costs of reinforced concrete infrastructure (bridges, tunnels, harbours, parking structures) are increasing due to aging of structures under aggressive exposure. Corrosion of reinforcement due to chloride ingress is the main problem for existing structures in marine and de-icing salt environments. Corrosion cannot be ruled out...

Estimating the Service Lives of Building Products in Use

Straub, A. (author)

Reliable service life data of building products are of great importance when completing environmental LCA (life cycle assessment) reviews, for LCC (life cycle costing) and for maintenance planning tasks. A research project was set up to answer the following research questions: (1) what are reliable service life data of current used building...

Aircraft bi-level life cycle cost estimation

Zhao, X. (author), Verhagen, W.J.C. (author), Curan, R. (author)

n an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This...

A Consideration on Deterioration Model for Cold Region Tunnel Lining Based on Life-cycle Concept

Sutoh, A. (author), Maruyama, O. (author), Kanakiyo, H.T. (author), Sato, T. (author)

This paper proposes the tunnel lining deterioration model which is based upon actual inspection data in order to carry out strategic maintenance and to rationalize life cycle cost analysis for tunnel structures. The evaluation value of deteriorating tunnel structures is a non-stationary stochastic process, and reliability problems of such...

Life Cycle Costs of Dutch school buildings

De Jong, P. (author), Arkesteijn, M.H. (author)

There is a gap between investment and operating costs of public school buildings in the Netherlands. This gap is caused by separated responsibility for the financing of the accommodation for the primary and secondary schools. Municipalities finance the initial costs of construction of these schools and school boards are responsible for the...

Service life and life cycle cost modelling of cathodic protection systems for concrete structures

Polder, R.B. (author), Leegwater, G. (author), Worm, D. (author), Courage, W. (author)

Corrosion of reinforcing steel in concrete structures causes concrete cracking, steel diameter reduction and eventually loss of safety. In infrastructure this is mainly due to penetration of chloride ions from de-icing or marine salts. Conventional repair means heavy, labour intensive and costly work and economic pressures (time and money) work...
