BREEAM Life cycle cost and service life planning

[edit] Aim and benefits

Deliver whole life value by orienting design and specification to a life cycle approach. Early stage understanding of the likely construction of the building and its servicing strategy, focuses the design team on likely requirements for service risers, ceiling void depth etc.especially for conditioned buildings requiring large amounts of plant - this can draw attention to the overall size requirements of the building and its projected costs, which may lead to alternative means of construction.

[edit] When to consider

At the earliest stage. Elemental level has to be completed before the end of RIBA Stage 2 and component level has to be completed before RIBA Stage 4.

[edit] Step by step guidance

Ensure all project team members are aware there is a time restriction on the achievement of this issue. Therefore, it is important to define RIBA stages at earliest opportunity and communicate them to all parties involved.

[edit] Questions to ask while seeking compliance

• Is a compliant ISO 15686 LCC study available?
• Does the design team have any experience of undertaking a BREEAM compliant LCC on any previous projects, can their experiences be shared with the o/a project team?
• Do they already have any templates that they can use?
• Are there any particular construction processes that lend themselves to favourable life cycle outcomes?

[edit] Tools and resources

Guidance on a compliant LCC analysis can be found in PD 156865:2008 Standardized method of life cycle costing for construction procurement - a supplement to BS ISO 15686-2:2008 Buildings and constructed assets, service life planning - Part 5.

PD 156865: 2008 is often quite a difficult document to get hold of? Ask the team if they have any extracts, search the Wiki for compliance details?

[edit] Tips and best practice

Collaboration in-between QS, architect and energy assessor at the early stage of the design development would allow to calibrate design for efficient and cost-effective solution.

[edit] Typical evidence

[edit] Design stage

• RIBA Stage 2 and RIBA Stage 4 reports from costing specialist
• LCC Report.
• File notes from project team demonstrating how LCC study impacted design decisions etc

[edit] Post construction

• Letter of confirmation from developer/contractor showing that the lowest LCC option (as selected at Design stage) has been implemented.

[edit] Applicable Schemes

The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances. See this document for further guidelines.

• UK New Construction 2014
• UK RFO 2014 (just check that the requirements are slightly different to NC)
