Ductwork – Whole Life Cost
The impact of different insulated HVAC ductwork specifications on whole life cost
In the construction industry, developers, funding bodies and manufacturers have historically focused on achieving a low capital cost in order to improve profits. However, for buildings that are let / rented out under contracts, which include ongoing maintenance and services provision by the lessor, or for buildings developed for forward thinking clients, operating cost can be as just important as capital cost in building design.
‘Whole life costing’ takes account of the total cost of an item over its life, including, but not limited to, capital, operating and maintenance costs. As a result, selecting the products, combination of products and systems that will satisfy the design requirements, at the lowest total cost, over the life of the project is critical in ensuring that whole life costs are minimized. This includes the ductwork specification and its insulation.
Kingspan Insulation commissioned independent consultants, Cyril Sweett, to carry out an analysis of the whole life costs of differing insulated HVAC ductwork specifications in the UK. The findings show that:
- The Kingspan KoolDuct System can provide a capital cost saving of over 21%
- over a 30 year life cycle, The Kingspan KoolDuct System can provide an operating and whole life cost saving of over 20%
A further analysis, utilizing empirical data derived from two separate buildings owned and operated by Luther Home of Mercy, was performed by mechanical and electrical engineering services firm, MDA Engineering Inc., in the US. The findings show that:
- The Kingspan KoolDuct System made a capital cost saving of over 16%
- over a 30 year life cycle, The Kingspan KoolDuct System is predicted to save over 14% on whole life cost
It is clear that, as a result of the findings described above, The Kingspan KoolDuct System should be considered the product of choice for insulated HVAC ductwork systems where whole life cost is a key requirement.
