Transcript of BREEAM Uncovered - Achieving the Life Cycle Costing Credits
About ADW Developments
ADW Developments is a consultancy that specialises in identifying and delivering best practice consultancy solutions
We help our clients assess the many design, specification and operation alternatives in order to derive a project solution that demonstrates value for money
What is Life Cycle Costing
What is Life Cycle Costing
ISO15686-1 (2000)
A technique that enables comparative cost assessments to be made over a specified period of time, taking into account all relevant economic factors both in terms of initial capital costs and future operational costs
Simple Definition
What needs to be done
How much will it cost
When will it happen
What is Life Cycle Costing

What is Life Cycle Costing
Ic + LCRc + Mc + Dc
Where :
Ic = Initial Costs;
LCRc = Life Cycle Replacement Costs
Mc = Maintenance & Operation Costs
Dc = Disposal Costs
BREEAM Life Cycle Costing and Service Life Planning
Life Cycle Costing for BREEMAssessment is made in collaboration with the
design team
Demonstrate that the selection if the most appropriate strategy to improve design, specification and through-life maintenance and operation
Carried out in accordance with ISO 15686, pt 1 and 5 and the PD Supplement
BREEAM 2011 3 credits; 2014 4 credits
Achieving the first credit
Report on the service life estimations and maintenance implications for various design and specifications
The appraisal is in accordance with ISO 15686 – Service Life Planning Part 1 Methodology
Reference Service Lives informed by our in-house service life database and third party datasets where appropriate
Achieving the first creditThe Whole Building Life Cycle Cost model
Initial cost model that forecasts the LCC based on the proposals developed during RIBA Work Stages C/D (concept design/design development) or equivalent
The LCC analysis is carried out over a study period of 60 years
Presented in real and discounted costs terms
Achieving the first credit The design life of the building is intended to be 50 years?
The life to first major maintenance is intended to be 25 years?
During the design life period components may require replacement, repair and/or maintenance to ensure the functional performance required from the building components is met
Estimated service life is based on a utility life The estimated time an asset can satisfy established functional performance
standards
That said, systems or components may require replacement or refurbishment due to other determinants such as:
Physical life: The period over which an asset is expected to last physically, to when replacement or rehabilitation is required;
Functional life: The period over which the need for an asset is expected;
Technological life: The period until technical obsolescence determines replacement as a result of technological superior alternatives;
Economic life: The period until economic obsolescence determines replacement with a lower cost alternative;
Social and legal life: The period until human desire or legal requirement determines replacement.
Achieving the first creditModel Assumptions
Life Cycle Replacement Costs Initial Capital Expenditure - Feasibility Study No 3 20140514
Reference Service Life → Estimated Service Life
Life Cycle Unit Rate (calculated as % of Initial Capital Expenditure)
Annual Maintenance Costs Decoration
Minor replacements, repairs and maintenance
Unscheduled repairs and replacements and maintenance
Grounds maintenance
Operations costs Windows and external services
Internal cleaning
Specialist cleaning
External works cleaning
Fuel
Water and drainage
Staff engaged in servicing the building
Rates and other local charges
Client definable costs
Achieving the second credit Assess components and identify the alternative design/ specification that has the lowest
discounted LCC over the period of analysis
Were the selection results in at least one of the following:
Lower building energy consumption
A reduction in maintenance requirement/frequency
Extended service lives
Dismantling and recycling or reuse of building components

Cumulative Component LCC @ Real Discounted Costs
Achieving the third credit Whole Building LCC model updated
Plan ahead – Contractor input needed at this stage
Written into the Employers Requirement Document
Similar requirement to the 1st credit
Advise which alternatives identified in the second credit can feasibly be implemented in the design and fi al construction
Prepare maintenance strategy report informed by the LCC analysis detailing maintenance and operational requirements to facilitate safe and cost-effective operation and maintenance
Useful to the operator, supports the O and M manual
Post Construction, support the BREEAM assessor (photographic evidence) to ensure compliance
