How to use this presentation
This presentation is a training tool for those wishing to use the
LCCA Tool, and train others in its use.
This presentation and the accompanying notes (using ‘Normal’
rather than ‘Slideshow’ view) explain how to operate the
spreadsheet by explaining its contents and showing example
calculations.
They also show you how to use the tool as part of the building
procurement process.

Notes on Using LCCA Tool for Buildings
PLEASE NOTE: We have kept the tool as simple as possible.
• As buildings are very complex and vary hugely the tool
cannot tell you all you need to take into account.
• A whole range of costs may need to be summed up in
one entry.
• You may need to devise your own checklist for tenders
that is relevant to the particular building type and
construction type.
• Ideally, this should be done in consultation with your
maintenance staff.
• Example 3 in this presentation will explain this further.

Replacement cycle and servicing
Unless you are comparing temporary
buildings the replacement cycle for a
building would be longer than 25
years.
However, individual elements may
need replacing. These may include:
• Windows and doors
• Floor finishes
• Façade cladding
• Paint finishes
• Mechanical services
• Renewable energy installations
• and others

The DEEP Toolkit. TOOL 2.b.Life Cycle Cost Analysis Tool-User Guide
Replacement cycle and servicing
As replacement cycles vary for the
different building elements, break
costs down into annual costs and
factor into maintenance
Also ask for cost of annual
maintenance for specific services
installations e.g.:
• Mechanical services (Heating,
ventilation, air-conditioning)
• Renewable energy installations
• Alarm systems
How to use the DEEP LeCCATo Life Cycle Costing Tool
• And others
The DEEP Toolkit. TOOL 2.b.Life Cycle Cost Analysis Tool-User Guide
Energy and Water use
Ask for energy consumption of
• Mechanical services (Heating,
ventilation, air-conditioning)
• Renewable energy installations
(=negative consumption)
• Alarm systems
• lighting
• Fans, pumps, controls
• Catering equipment
• and others as applicable
Ask for water consumption
