Integrating Life-Cycle Cost and Environmental Impact for Sustainable Building Procurement

Procurement models that integrate life-cycle cost and environmental impact assessment can incentivize more sustainable building solutions and lead to cost-effective, environmentally aware buildings.

Epubl LTU · 2002

01

Key Findings

  • 01Environmental requirements in Swedish procurement often focus on construction processes, waste reduction, and material choice.
  • 02Some existing requirements hinder cost-effective construction without significant environmental benefit.
  • 03Environmental impact from building operation, especially energy use, is not sufficiently considered.
  • 04Integrating life-cycle cost and environmental impact assessment in tender evaluation can incentivize innovative, sustainable solutions.
02

Application

Design takeaway

Adopt a holistic approach to building design and procurement by evaluating both the initial costs and the long-term environmental and economic impacts throughout the building's entire life cycle.

How to apply

When evaluating building proposals or developing design strategies, create a matrix that scores options based on both life-cycle cost projections and quantified environmental impact metrics (e.g., carbon footprint, energy consumption).

Project actions

  • 01When researching materials, look for data on their full life cycle, from production to disposal.
  • 02Consider how your design choices will affect a building's energy consumption during its operational phase.

Method & Evidence

AimCan a practical model integrating life-cycle cost and environmental impact assessment be developed for tender evaluation and design phase decision-making in building procurement?
MethodMixed-methods research combining quantitative surveys and qualitative interviews.
ProcedureInvestigated environmental requirements in Swedish building procurement through questionnaires and interviews. Analyzed requirements for their impact on environmental reduction and cost-effectiveness. Explored life-cycle cost estimation practices via surveys and a seminar.
ContextBuilding procurement and construction industry, with a focus on Swedish clients and practices.

Strengths & Limitations

Strengths

  • +Addresses a critical gap in sustainable building practices.
  • +Proposes a practical framework for integration in procurement.

Limitations

Accurately predicting long-term operational costs and environmental impacts can be challenging due to many variables.

Reliability & validity

The reliability of survey data depends on respondent honesty and recall. Validity is enhanced by triangulating survey data with interview findings and expert discussions.

Think critically

To what extent can a standardized life-cycle assessment model be universally applied across diverse building types and geographical locations, given varying regulations, climates, and material availability?

05

Design Principles

"Sustainable design and procurement require a life-cycle perspective that balances initial investment with long-term environmental and economic performance."

This research highlights a critical gap in traditional building procurement, where environmental considerations, particularly operational energy use, are often overlooked in favor of initial construction costs. By developing integrated models, design professionals can better evaluate the long-term value and ecological footprint of building projects, driving innovation towards more sustainable outcomes.

06

What This Means for Your Design

To build better buildings, think about the whole life of the building, not just how it's built. Consider how much energy it will use and how much it will cost to run over many years, not just the price to build it now. This helps choose designs that are good for the planet and save money in the long run.

How to use in your project

  • 1.Use the concept of life-cycle assessment to justify the selection of materials or design strategies that have lower long-term environmental impact and cost.

Paragraph starter

This design project adopts a life-cycle perspective, recognizing that the true cost and environmental impact of a building extend far beyond its initial construction. By integrating life-cycle cost estimation with environmental impact assessment, as suggested by Sterner (2002), the aim is to identify design solutions that are both economically viable and ecologically responsible over the building's entire lifespan.
