2009-07-11: Practical Implementation of Sustainable Human & Social Development … transforming our Human Environment by gradually improving and monitoring ‘Real’ Sustainability Performance … depends entirely on directly applying a Multi-Aspect Understanding of ‘Sustainability’, in a manner which is both balanced and equitable, to all of the many different facets of Sustainable Design.
Therefore … responding ethically and professionally, in built and/or wrought (worked) form, to the still evolving concept of Sustainable Human & Social Development …
… the specific aim of Sustainable Fire Engineering shall be to design for Maximum Credible Fire & User Scenarios … in order to maintain a proper and satisfactory level of fire safety and protection over the full life cycle of a building.
[Sustainable Fire Engineering can be applied, equally, to other elements of the Built Environment, e.g. means of transport on land or sea.]
As discussed in a previous post … the Minimum Life Cycle of a Sustainable Building is 100 Years. AND, to prolong Building Life Cycle and maximize Building Usability … such a building must be Flexible and Adaptable with regard to internal layout, Accessible for People with Activity Limitations (2001 WHO ICF) … and Structurally Robust.
Maximum Credible Fire Scenario:
A sequence of events during a ‘real’ fire incident in a building – related to design, construction, occupancy, fire loads, ignition sources, spatial geometry, fire protection measures (both passive and active) … and an adverse, but reasonable to anticipate, operation and management status – which culminates in fire conditions which are severe, but reasonable to anticipate over a complete building life cycle.
Maximum Credible User Scenario:
Indicates building user conditions which are also severe but reasonable to anticipate over a complete building life cycle, i.e. …
- the Number of People Using a Building increases, on occasions which cannot be specified, to 120% of Calculated Maximum Building Capacity ;
- 10% of People Using the Building (occupants, visitors & other users) have an Impairment (visual or hearing, physical function, psychological, mental or cognitive … with some impairments not being identifiable, e.g. anosognosia).
Sustainable Fire Engineering Strategy:
A coherent and purposeful arrangement of fire protection and fire prevention measures which is developed in order to meet specified Sustainable Fire Engineering Design Objectives.
In designing a building for conditions of fire, and its aftermath, project-specific Sustainable Fire Engineering Design Objectives typically cover the following spectrum of concerns …
- Protection of the Health and Safety of All Building Users … including people with activity limitations, visitors to the building who may be unfamiliar with its layout, and contractors or product/service suppliers temporarily engaged in work or business transactions on the premises ;
- Protection of Property … including the building, its contents, and adjoining or adjacent properties, from loss or damage ;
- Protection of the Health and Safety of Firefighters, Rescue Teams and other First Response Personnel ;
- Protection of the Natural Environment from Harm, i.e. adverse impacts ;
- Facility, Ease and Cost of carrying out Effective Repair, Refurbishment and Reconstruction Works after the Fire ;
- Sustainability of the Human Environment (Social, Built, Virtual, Economic … ).
