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 Normalrather 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.

OPTION2:

Low energy office with night-

time concrete slab cooling,good day lighting, heavy

OPTION2:

same as Option 2, but with

electric heating

5.85 million

Replacement cycle and servicing

Unless you are comparing temporarybuildings the replacement cycle for a

building would be longer than 25

years.

However, individual elements may

need replacing. These may include:

Windows and doors

loor finishes

aade cladding

Paint finishes

echanical services

Renewable energy installations

and others



32/37


Replacement cycle and servicing

As replacement cycles vary for the

different building elements, breakcosts down into annual costs and

factor into maintenance

Also ask for cost of annual

maintenance for specific services

installations e.g.:

echanical services (Heating,

ventilation, air-conditioning)


Alarm systems

And others



33/37


Energy and Water use

Ask for energy consumption of

echanical services (Heating,

ventilation, air-conditioning)


(=negative consumption)

Alarm systems

lighting

ans, pumps, controls

Catering equipment

and others as applicable

Ask for water consumption
