Bianchini, F., & Heage, K. (2012). Probabilistic social cost-benefit analysis for green roofs: A lifecycle approach. Building and Environment 58 (2012) 152-162. Retrieved from https://doi.org/10.1016/j.buildenv.2012.07.005.

This article explains the costs of installing and maintaining different types of green roofs and its long term and social benefits. A simple extensive roof which has no public access would cost significantly lesser than an intensive green roof which has public access. “Intensive roofs are associated with roof gardens; need a reasonable depth of soil and require constant maintenance. Extensive roofs have a relatively thin layer of soil, and are designed to be virtually self-sustaining, therefore require low maintenance.”. Although green roof cost significantly higher, it would offset the cost by saving on utility costs and rainwater management and has a longer lifespan compared with conventional roofing materials. The maintenance regime consists of ‘fertilisation, irrigation, weed control, and replanting when required’.

Bianchini and Heage (2012), claimed that researchers conducted a lifespan cost on green roofs, cool roofs and conventional roofs. They concluded that while green roofs are expensive, it does provide significantly higher relative benefits over a 50-year lifecycle in terms of energy cost savings, reducing emissions, reducing stormwater fees. Compared to conventional roofs and cool roofs, green roofs provide more significant benefits in the long run. This article is comprehensive for those wanting to explore the cost of green roofs on new buildings. However, for those who wish to retrofit green roof on existing structures, i.e. which are above thirty years, would it still be cost-effective is a question to ponder. As to reap the benefit of a green roof requires long term whereas older existing buildings could post an indefinite payback period.

In the article ‘Eight Failures that Left People of Grenfell Tower at Mercy of the Inferno’, Knapton and Dixon (2017) claimed that the Grenfell Tower had numerous lapses in both ‘building regulation and safety rules’, which further augmented during the incident.

Buildings in London followed the Building Acts until 1986 whereby external walls had to have at least one hour of fire resistance. ‘Class O’ regulation was introduced which removed the initial requirements regardless of the material was combustible. A specialist in fire protection remarked the gap between the claddings exacerbated the fire to upper levels. Knapton and Dixon (2017) highlighted that although the materials used for the cladding met the UK standards, it contributed the fire to spreading and made fire-fighting impractical. There was no explicit instruction on the fire risk assessment nor updated building regulations and it was not mandatory to have more than one escape route. Knapton and Dixon (2017)  reported that, according to sources, not all doors were fire-rated.  In addition sprinklers were only required to be installed up to 30 metres, which left taller buildings omitting them on their upper levels. Experts shared that the firebreaks, which were a requirement under Building Regulations 1991, were not serving their purpose during the fire.

The authors described the events and different perspective of the fire. They pointed out about the ambiguity of the authorities in the relevant building regulations, fire and safety rules. In my opinion, the authorities did play an extensive role in failing to control the fire. However, I believe there were only two reasons instead of eight: namely, no appropriate building regulation and inadequate fire and safety directive.

Firstly, appropriate building regulation was required. According to the UK Building Regulations (2010)a building regulation sets a national standard for buildings to protect people. Ironically, in the Grenfell Tower, the fire spread from the source to the back of the' UK approved' cladding, which rose up to the roof and eventually enclosed the building. Sadly the cladding material only required to satisfy of not spreading the flames over the surface. Knapton and Dixon (2017) mentioned that both the gap and the combustible material at the back of the cladding was the catalyst for the spread of the fire. According to Doward (2018), investigators determined the back of the cladding made of aluminium composite tiles was flammable. It was suggested that, if the cladding were of non-combustible material, the fire would not have pulsated back to the cladding. The firefighters would have supposedly ended the fire within the section of origin.

Secondly, an adequate fire and safety directive was needed. According to the London Fire Brigade (n.d.), fire safety regulations are paramount as they are 'designed to save lives and protect both people and property'. In contradiction, lives lost in the catastrophe could be saved hypothetically, even though the cladding was the primary reason for the ‘inferno’.  Included in the fire safety regulation, the combination of from the insufficient sprinklers to the only escape route and failed fire breakers it all boils to the lack of proper fire and safety rules. Ministry for Housing, Communities and Local Government, (2018), report to the parliament, recommended a complete review of both the building regulations and fire safety laws. Kenber and Kennedy (2017) expressed that, if the building regulation had been reviewed and published after the fire in Lakanal House, which took six lives, as seriously as the Grenfell Tower these lapses would have been spotted out earlier and consequent buildings could have been saved from imperilment. In the case of the Grenfell Tower, it would have at least saved the lives and left the building to the 'inferno'. 

Thus, it is evident that the lack of a proactive approach and procrastination to update the superseded building and fire and safety regulation was the catalyst for the whole ordeal. The authorities did not need a massive catastrophe to give them a rude awaking on their roles and responsibilities.

According to the UK Building Regulations (2010), a building regulation sets a national standard for buildings to protect people with a provision of safety. In irony, the fire spread from the source to the back of the' UK approved' cladding which rose up to the roof and eventually enclosed the building. Sadly the cladding material only required to satisfy the requirement of not spreading the flames over the surface. It did not matter of its properties at the back. Knapton and Dixon (2017) distinguished that both the gap and the combustible material at the back of the cladding was the catalyst for the spread of the fire. According to Doward (2018), investigators itemised the back of the cladding made of aluminium composite tiles was flammable. Hypotheses if the cladding were of non-combustible material, the fire would not pulsate out to the cladding. The firefighters would have supposedly ended the fire within the section of origin.

Concurring to London Fire Brigade (n.d.), fire safety regulations are of paramount as they are 'designed to save lives and protect both people and property'. In contradiction, so much should have been done to save the lives lost in the catastrophe, even though the cladding is the primary reason for the ‘inferno’.  The synthesis from the insufficient sprinklers to the only escape route and failed fire breakers it all boils to the lack of proper fire and safety rules. According to Secretary of State for Housing, Communities and Local Government, (2018), in the final safety report to the parliament was to have a complete review of both the building regulations and fire and safety laws. The Times (2017) expressed that if the building regulation had been reviewed and published after the fire in Lakanal House, which took six lives, as seriously as the Grenfell Tower these lapses would have been spotted out earlier and consequent buildings could have been saved from imperilment. Lapses such as the ‘stay put’ policy which was equivocal. Theoretical it might seem valid but in reality, the environment usually being dynamic would be preferably best to find a way to evacuate. In the case of the Grenfell Tower, it would have at least saved the lives and leaving the building solitary to the 'inferno'. 

Thus, it is evident that the lack of proactiveness and procrastination to update the superseded building and fire and safety regulation was the reason for the whole ordeal. The authorities did not need a massive catastrophe to give them a rude awaking on their roles and responsibilities.

In my opinion, the government did play an extensive role in the fire. One example would be minimal, or no action was taken from previously raised concerns about fire regulations from salient incidents, before this catastrophe.

Initially, the fire could have been contained locally in the kitchen. In irony, the UK approved cladding spread the fire from the source to the back of cladding which rose up to the roof and eventually enclosed the building. The cladding material only required to satisfy the requirement of not spreading the flames over the surface. It did not matter of its properties at the back. Both the gap and the combustible material at the back of the cladding was the catalyst for the spread of the fire.

According to  Hackitt, in her final safety report to the parliament was to have a complete review of the building regulations. If the building regulation has been reviewed after the fire in Lakanal House, which took six lives, as seriously as the Grenfell Tower these lapses would have been spotted out earlier and consequent buildings could have been saved from imperilment.
