Industrialised off-site deep retrofitting approaches can be economically competitive with traditional on-site methods, especially when considering the entire lifecycle, including operation, maintenance, and component reuse. This commercial production research insight is drawn from a 2023 study published in Journal of Facade Design and Engineering. Using Comparative life cycle costing (lcc) analysis., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritise lifecycle cost analysis over initial investment alone when choosing between traditional and industrialised building retrofit methods, and design for component reuse where possible.

Key Findings
- 01Initial investment costs for traditional and industrialised deep retrofit approaches are comparable, with a potential gap of -7% to +16%.
- 02The operation and maintenance phase significantly impacts the Net Present Value (NPV), favouring industrialised components due to their expected higher quality and longer lifespan.
- 03Reusing dismantled components in the industrialised scenario at the end of life can substantially increase its overall economic value.
Application
Design takeaway
Prioritise lifecycle cost analysis over initial investment alone when choosing between traditional and industrialised building retrofit methods, and design for component reuse where possible.
How to apply
When planning a building renovation, conduct a detailed Life Cycle Costing analysis that accounts for all expenses from construction to disposal, and explore opportunities for modular or prefabricated components that can be reused.
Project actions
- 01When analysing costs for your design project, think beyond the purchase price and consider how much it will cost to use and maintain the product over its entire life.
- 02Investigate if any materials or components in your design could be easily disassembled and reused or recycled at the end of the product's life.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilises a robust Life Cycle Costing methodology.
- +Includes a comprehensive analysis from design to end-of-life phases.
- +Based on real cost data from industry professionals.
Limitations
The cost savings from component reuse are highly dependent on the specific materials and the availability of secondary markets, which may not be present in all contexts.
Reliability & validity
The study's reliability is supported by the use of real cost data and a structured LCC methodology. Validity is enhanced by analysing multiple phases of the building lifecycle. However, the specific context of Italy and the analysed building type may limit generalisability.
Think critically
To what extent do the 'expected higher quality' and 'prolonged life expectancy' of industrialised components translate into measurable cost savings in real-world, long-term applications, and what factors might prevent this?
Design Principles
"Economic viability is optimised through a holistic lifecycle assessment that includes operational efficiency and end-of-life value."
This research provides crucial economic data for design and construction professionals evaluating deep retrofit strategies. Understanding the long-term financial implications beyond initial investment can lead to more sustainable and cost-effective building upgrades.
What This Means for Your Design
When you renovate a building, using pre-made parts from a factory (industrialised) can cost about the same at first as building on-site (traditional), but it can save you more money over time because the factory parts might last longer and you might be able to reuse them later.
How to use in your project
- 1.Reference this study when justifying your choice of materials or construction methods based on economic factors beyond initial purchase price, especially in projects involving renovations or sustainable design.

Paragraph starter
This research highlights that industrialised building retrofit methods, while comparable in initial investment to traditional approaches, offer significant long-term economic benefits through reduced operational and maintenance costs and the potential for component reuse at the end of life. This supports a design approach that prioritises lifecycle value over immediate expenditure.
