I was very pleased to make a Presentation at both events, adapted to suit an Irish context, on … ‘Sustainable Fire Engineering – Necessary Professional Transformation For The 21st Century’ … which continues to evolve.

Sustainable Fire Engineering:  The creative, person-centred and ethical Fire Engineering response, in resilient built form and smart systems, to the concept of Sustainable Human and Social Development … the many aspects of which must receive synchronous and balanced consideration !

Presentation Abstract

Annual Fire Losses, both direct and indirect, amount to a very significant percentage of Gross Domestic Product (#GDP) in all economies, whether they are rich or poor … and result in enormous environmental devastation and social disruption.  Some losses have not yet been fully identified, e.g. environmental impact … while others are not yet capable of being fully quantified, e.g. business interruption, brand and reputation damage.  Globally, fire statistics still remain unreliable.  In all cases, however, the waste of valuable human and natural resources caused by preventable fires is unsustainable and no longer acceptable.

From an entirely different perspective … Sustainable Buildings are presenting every society with an innovative and exciting re-interpretation of how a building functions in response to critical energy, environmental, climate change and planetary capacity pressures … an approach which has left the International Fire Engineering and Firefighting Communities far behind in its wake, struggling to develop the necessary ‘creative’ and ‘sustainable’ fire safety strategies.

The Aim of Sustainable Fire Engineering (#SFE) is to dramatically reduce direct and indirect fire losses in the Human Environment (including the social, built, economic, virtual, and institutional environments) … to protect the Natural Environment … and, within buildings, to ensure that there is an effective level of Fire Safety for All Occupants, not just for Some, over the full building life cycle.

The following Priority Themes for SFE lie outside, or beyond, the constrained and limited fire safety objectives of current fire regulations, codes and standards – objectives which do not properly protect society, a fire engineer’s clients, or the facility manager’s organization:

  1. Fire Safety for ALL, not just for Some.  Nobody left behind !
  2. Firefighter Safety.  Everyone goes home !   It is easy to dramatically improve firefighter safety with building design.  So, why haven’t NIST’s 2005 and 2008 WTC 9-11 Critical Recommendations been properly implemented anywhere ?
  3. Property Protection.  Fire damage and post-fire reconstruction/refurbishment are a huge waste of resources.  On the other hand, protection of an organization’s image/brand/reputation is important … and business continuity is essential.  Heritage fire losses can never be replaced.
  4. Environmental Impact. Prevention of a fire is far better than any cure !   But prevention must also begin by specifying ‘clean’ technologies and products.  Low Pressure Water Mist Systems are not only person/environment-friendly and resource efficient … they are absolutely essential in airtight and hyper energy-efficient building types (e.g. LEED, PassivHaus, BREEAM) in order to achieve an effective level of fire safety for all occupants, and firefighters.    [ Note: Environmental Impact Assessment (#EIA) has been superseded by Sustainability Impact Assessment (#SIA).]
  5. Building Innovation, People and Their Interaction.  Fire engineers and firefighters must begin to understand today’s new design strategies.
  6. Sustainable Design and Engineering. Wake up and smell the coffee !   Legislation can only achieve so much.  Spatial planners, building designers and fire engineers must subscribe to a robust Code of Ethics * which is fit for purpose in the Human Environment of the 21st Century.

Sustainable Fire Engineering Solutions are …

  • Adapted to a local context, i.e. climate change/variability/extremes, social need, geography, economy, and culture, etc ;
  • Reliability-based – lessons from real extreme and hybrid events, e.g. 2001 WTC 9-11 Attack, 2008 Mumbai/2015 Paris/2016 Brussels Hive Attacks and the 2011 Fukushima Nuclear Incident, are applied to frontline practice ;
  • Person-centred – real people are placed at the centre of creative endeavours and due consideration is given to their responsible needs, and their health, safety, welfare and security in the Human Environment ;
  • Resilient – functioning must be reliable during normal conditions, and include the ability to withstand, adapt to and absorb unusual disturbance, disruption or damage, and thereafter to quickly return to an enhanced state of function.

After Grenfell: Reliable Design, Supply & Construction Essential !

2017-10-10:  After the Grenfell Tower Fire Tragedy in London, on 14 June 2017, the integrity of the English Regulatory and Technical/Building Control Systems is now so compromised that a complete Systems Transformation is immediately required !   Closer to home, here in Ireland … what nobody is daring to say, even our tame media, is that Our Regulatory System is based very closely on the English System.  And Our Technical/Building Control System is purposefully under-resourced … so it is weak and ineffective.

Let there be no confusion … Priory Hall and Longboat Quay, both in Dublin, are just the tip of an enormous iceberg …

So where do we start again ?

Reality – Reliability – Redundancy – Resilience !

With regard to Reliable Fire Engineering Related Design, Supply and Construction … this is how we must proceed …

  1. Design of the works is exercised by an independent, appropriately qualified and experienced architect/engineer/fire engineer, with design competence relating to the fire protection of buildings ;
  1. Supply of fire safety related construction products/systems to the works is undertaken by reputable organizations with construction competence, particularly in relation to the fire protection of buildings ;
  1. Installation/fitting of fire safety related construction products/systems is exercised by appropriately qualified and experienced personnel, with construction competence relating to the fire protection of buildings ;
  1. Supervision of the works is exercised by appropriately qualified and experienced personnel from the principal construction organization ;
  1. Regular inspections, by appropriately qualified and experienced personnel familiar with the design, and independent of both the design and construction organizations, are carried out to verify that the works are being executed in accordance with the design.

Sick Building Syndrome, ISO 21542:2021 & Indoor Air Quality (IAQ)

2012-05-31 (2021-08-02):  The Revised International Standard  ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’  was published on 1 June 2021.  Many years before, however, a decision was taken to link this Standard directly to the United Nations  Convention on the Rights of Persons with Disabilities  (#CRPD) … specifically now referencing Preamble Paragraph (g) and Articles 9, 10, 11, 12 and 19 in its Introduction.  Reading the document, this linkage looks and feels very naturally like an unbreakable umbilical cord !

.

ISO 21542 has significantly widened the meaning of the concept #Accessibility4ALL … a normal evolutionary process … in particular, the #FireSafety4ALL Texts.  I wonder, though, how many people would ever have considered  Good Indoor Air Quality  to be on the ‘Accessibility’ Menu ??

Much lower rates of direct fresh air ventilation … and a dramatic reduction in accidental or unintended air seepage from, or into, buildings (depending on local climate conditions) … all driven by an urgent need to conserve energy and to impose greater energy efficiencies on the energy which is actually consumed … are, once again, one of the main causes of serious health problems for ALL #BuildingUsers …

Building Related Ill-Health:  Any adverse impact on the health of building users – while living, working, generally occupying or visiting a specific building – caused by the planning, design, construction, management, operation or maintenance of that building.

I say “once again” because, in Europe, we have been here before … after the two big oil crises of the 1970’s.

.

Anyway … I thought that it would be useful to present a relevant extract from ISO 21542

B.8 – INDOOR AIR QUALITY (#IAQ)

Poor indoor air quality, an important factor in relation to Building Related Ill-Health (also known as ‘sick building syndrome’), can cause serious health impairments and severely restrict a person’s participation in everyday activities, e.g. work.

Symptoms and signs may include:

  • irritation of eyes, nose and throat ;
  • respiratory infections and cough ;
  • voice hoarseness and wheezing ;
  • asthma ;
  • dry mucous membrane and skin ;
  • erythema (reddening or inflammation of the skin) ;
  • lethargy ;
  • mental fatigue and poor concentration ;
  • headache ;
  • stress ;
  • hypersensitivity reactions, i.e. allergies ;
  • nausea and dizziness ;
  • cancers.

These symptoms and signs are present in the population at large, but are distinguished by being more prevalent in some building users, as a group, when compared with others.  The symptoms and signs may disappear, or may be reduced in intensity, when an affected person leaves the building.  It is not necessary that everyone in a building should be affected before building related ill-health is suspected.

ISO 16814: ‘Building Environment Design – Indoor Air Quality – Methods of Expressing the Quality of Indoor Air for Human Occupancy’ covers methods of expressing indoor air quality (IAQ) and incorporating the goal of achieving good IAQ into the building design process.  It also covers ventilation effectiveness, harmful emissions from building materials, air cleaning devices, and heating, ventilation and air conditioning equipment.

The indoor pollutants considered in ISO 16814 include human bio-effluents, which have often been the principal consideration in air quality and ventilation design, but also the groups and sources of pollutants which can reasonably be anticipated to occur in the building during its long Life Cycle.

These pollutants, depending on the sources present, may include:

  • volatile organic compounds (#VOC’s) and other organics, such as formaldehyde ;
  • environmental tobacco smoke (#ETS) ;
  • natural radon, consisting of a number of different isotopes, is an invisible radioactive gas, and is found in the soils under buildings, water supplies to buildings and in the air ;
  • other inorganic gases, such as carbon monoxide (#CO), the oxides of nitrogen (NOx), and low-level ozone (smog) which is formed when NOx and VOC’s react in the presence of sunlight ;
  • viable particles, including viruses, bacteria and fungal spores ;
  • non-viable biological pollutants, such as particles of mites or fungi and their metabolic products ;
  • non-viable particles, such as dusts and fibres.

The following Two Performance Indicators of Good Indoor Air Quality, developed with the aim of protecting human health, are recommended:

  1. Radon Activity (including Rn-222, Rn-220, RnD)  in a building should, on average, fall within the range of 10-40 Bq/m3, but should at no time exceed 60 Bq/m3.
  2. Carbon Dioxide (CO2)  concentrations in a building should not significantly exceed average external levels – typically within the range of 300-500 parts per million (#PPM) – and should at no time exceed 800 ppm.

[ While the current CoVID-19 Pandemic lasts … these are Essential ‘Health’ Performance Indicators, as opposed to ‘Safety’ Indicators … and they should be stringently operated and constantly monitored in all building types. ]
