Whole Life Costing and Performance


Whole Life Costing (WLC) includes the systematic consideration of all costs and revenues associated with the acquisition, maintenance, occupancy and disposal of a building. According to ISO 15686, Part 5 WLC can be defined as: “economic assessment considering all agreed projected significant and relevant cost flows over a period of analysis expressed in monetary value. The projected costs are those that are needed to achieve defined levels of performance, including reliability, safety and availability”.

Until a few years all the attention of investors, architects and contractors was aimed at reducing construction costs, and there is little attention paid to participants to reduce maintenance costs and use of buildings, or more importantly, reduce overall project costs.

The new types of procurement (PFI, PPP and PC) require the companies involved to take long-term responsibility for building operation and maintenance.



Our goals:

  • Establish the most cost-effective investment decisions
  • Optimise costs of an asset through its anticipated life span
  • Establish trade-offs on capital, maintenance and operation costs
  • Sustainability agenda a high priority in today’s economy
  • WLC evaluator software to produce models incorporating industry-accepted cost structures


Increased attention is being paid to planning and reducing the cost of using and maintaining structures, as shown in the design stage, it can affect 70% to 80% of the costs of maintenance and operation such as significant life cycle costs of future buildings.

The annual cost of use of buildings can exceed the cost of their construction by 10%, operational cost of non-residential buildings may rise up to 25%, and the average rate of increase in cost of the operation can be up to 4.50% per year.


Whole life cost of facility

Clients want the best possible value for money from their assets. One of the ways to achieve this is to reduce whole life costs. One way of reducing WLC is by implementing a systematic approach which allows the project team to trade-off between the client’s requirements, operational performance and availability of the facility, capital cost and future running costs.


PPP Centar approach to whole life cycle costing:

considers and optimizes the full range of costs which occur from the construction of an asset right through its anticipated life span.

Whole Life Costing is a key driver in both public and private sector works and is considered a necessity in PPP and PFI projects in terms of long-term operation, risk and the life cycle replacement of key components.

Whole Life Cost analysis is very important part in sustainable building projects which could enable and analyse economic indicators known as Sustainable Assessment of Buildings.
