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.

Examples

The following examples will illustrate how to

use the LCCA Tool in practice.

Please note that the examples do not contain

accurate data, and are for illustrative purposes only.



Example 1 : energy efficient lighting

Example 3: Office Buildings

OPTION 1:

Standard office building air conditioned

€ 5.5 million

OPTION2:

Low energy office with night-time concrete slab cooling,

good day lighting, heavy mass.

€ 6 million

OPTION2:

same as Option 2, but with electric heating

€ 5.85 million



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



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

• And others



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
