BREEAM Designing for durability and resilience
 Aim and benefits
The aim is to encourage and recognise adequate protection of exposed elements of the landscape and building. This will lead to minimising the frequency of replacement and maximising materials optimisation.
 When to consider
The architects should consider the requirements and identify vulnerable areas as early in the design process as possible. Collaborate with the landscape designer and M&E engineers to allow for any potential measures affecting the lifetime of the materials.
their associated costs, when designing and specifying materials for a new building. Also to consider the impact of climate change on the external materials. This considerations are expected to be included in the specifications.
 Step by step guidance
The design should be reviewed to identify any areas vulnerable to damage both internally and externally and where possible the risk should be removed. Where this is not possible, the risk should be reduced by specifying protection measures. Drawings should be marked up to identify the risk areas both internally and externally. This could include areas of the building at risk from damage from vehicle movement i.e. close to vehicular parking or manoeuvring; internal vehicular/trolley movement or areas of high pedestrian traffic such as main entrances, public areas and circulation routes.
Suitable durability and protection measures to vulnerable parts of the building can include:
- Bollards/barriers/raised kerbs to delivery and vehicle drop-off areas
- Robust external wall construction, up to 2m high
- Corridor walls specified to Severe Duty (SD) as per BS 5234-2 and for Healthcare Buildings - HTM 56
- Protection rails to walls of corridors where trolley movement is likely
- Kickplates/impact protection (from trolleys etc) on doors
- Hard-wearing and easily washable floor finishes in heavily used and circulation areas (i.e. main entrances, corridors, public areas etc)
- Designing out the risk without the need for additional materials specification to protect vulnerable areas.
Vehicular impact protection must be positioned at an adequate distance from the building to protect the fabric from impact from any vehicle with a measurable overhang of the body from the wheel track, in particular in any goods delivery areas.
The process to assess criteria 2 is:
- Identify from the list of ‘applicable building elements’ under Table 50 the elements that are appropriate to the building being assessed.
- Establish from the ‘environmental factors’ list those factors that are likely to cause material degradation effects in the identified applicable building elements.
- Confirm the design and specification measures in place to limit these degradation effects.
- The assessor should use their professional judgement in determining whether the design team have adequately demonstrated that they have designed and specified materials and/or measures which will be effective in preventing unnecessary deterioration, so reducing frequent replacements, repairs and maintenance through the life cycle of the building.
- At post construction stage, where the design and specification measures installed differ from those proposed at design stage, the assessor must ensure that these measures still meet the aims of the criterion as detailed in point 4 above.
 Protecting exposed parts of the building from material degradation
Need to show that exposed parts of the building are protected from degradation. This covers the following elements and only apply if they are exposed to the external environment:
- Foundations, substructure, lowest floor, retaining walls
- External walls
- Glazing – Windows/skylights
- External Doors
- Hard landscaping
Under this you need to state which environmental factors apply:
- Environmental agents
e) Precipitation – rain and snow
f) Extreme weather conditions – high wind speeds, flooding, driving rain, snow
- Biological agents
h) Pests, insects
- Environmental agents
i) Air contaminants
j) Ground contaminants
Material degradation effects could include the following:
- Dimensional change e.g. swelling or shrinkage
- Fading / discolouration
- Salt crystallisation
Suggested format for evidence is a table with the following headings:
|Applicable Building Elements||Environmental Factors||Possible Degradation Effects||Measures to Minimise Effects|
 For Shell Only or Shell and Core assessments:
Where vulnerable elements identified are internal and do not form part of the shell and core developer’s remit, i.e. they are within speculative areas and compliance is subject to the tenant’s/future occupier’s fit-out specification, these areas can be excluded from assessment.
 Questions to ask while seeking compliance
- Is there any specific areas in the building which you would classify as vulnerable.
- Whether there are any specific procedures and specific materials required for the building type
- Have you considered specific measures to increase the resilience and durability of materials in these areas?
- What measures are considered?
 Tips and best practice
 Typical evidence
 Design Stage
- Marked up plans/drawings identifying vulnerable areas of the building internally and externally
- Design drawings/specifications showing protection measures incorporated to prevent damage
- Schedule identifying measures to protect from material degradation listing applicable building elements, applicable environmental factors, material degradation effects and any measures specified to mitigate the possible degradation.
 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.
