BCA

• Tick-box solution

• Accuracy and scalability of small tests questionable

• ‘Silo’ approach to design

Linear Route

• Large scale testing of entire system

• Only applicable to the precise system tested.

Performance based route: Option 1Exacting System Test Data

BR 135 to BS8414

Performance based route: Option 2desktop study report

• Allows scalability

• Should be based on clear empirical data

• Currently no standard data requirement or format

The Fire Safety Engineering Route

• Comprehensive, holistic & thorough

• Allows innovative design

• Best for protecting life & property

• Added complexity and cost

Recommended Improvements

1. Extend Large Scale Testing2. Reform Desktop Studies3. Accredited Training Providers4. Additional Controls to Ensure ‘As Built’ Matches

Design

1. Extend Large Scale Testing

• No linear route to compliance

• BR135 - BS8414 applied to all cladding systems

• Retained but reformed

• Public register of desktop studies

• Mandatory requirements for assessors

• Clarity on what data can and cannot be used

• Identify scalable testing ofcomplete system

2. Reform Desktop Studies

Medium Scale test to discriminate between different claddings

• Could medium scale test (ISO 21367) provide accurate estimate of performance to LEPIR 2?

• 12 different cladding systems were selected

• Wooden frame, Kingspan K15 Insulation and 20mm Cavity

Results

• Fire-safety mandatory in façade contractor training

• Create accreditation system

3. Contractor Training

• Specification must be robustly protected

• Architects

• Building Control

4. Better Control of Specification
