Allegion On Upgrading The Built Environment: A Retrofit Project

Re-development, restoration, retrofit. No longer are these terms modestly viewed as construction buzzwords. Across the world, there’s an increasing appreciation and a budding culture that maintaining older buildings is the way forward for the planet and its people.

Globally, cities are said to be responsible for 78% of the energy consumption, of which, buildings account for around a third of the total. And when users consider that up to 80% of the current buildings are expected to still be in use by the year 2050, it’s evident why so many are pushing for a conscientious approach.

Unlocking the potential of retrofitting 

"Across the UK, the built environment also contributes 40% to the country’s total carbon emissions, with its 28 million homes, by most assessments, constituting the least energy efficient in Europe. With so many of our current buildings set to exist 30 years into the future and beyond, why should so much focus fall on new-build projects? Output must be improved now, and the real substance of the challenge is retrofitting, we need only unlock its potential," says Karen Trigg of Allegion UK.

Building efficiency 

A retrofit is often described as the addition of new components or features to older systems"

Karen Trigg adds, “Despite its many applications, in the context of the built environment, a retrofit is often described as the addition of new components or features to older systems."

She continues, "The process is designed to make a building perform better, and because of its benefits both economically and environmentally speaking retrofitting has emerged as a popular solution for advancing the efficiency of buildings."

Energy consumption

Karen Trigg said, “On an environmental level, it’s widely understood that the construction industry must strive to do better. In many developed countries, four out of the five buildings set to stand in 2050 already exist, meaning the onus of addressing energy consumption lies upon us now."

She adds, "Accordingly, decision-makers are obliged, and actively encouraged, to prioritize activities such as retrofitting to meet the energy-saving targets as outlined in the Paris Agreement."

Cost savings 

Karen Trigg continues, “In terms of cost savings, the process of adding better functioning components to our buildings will benefit many. Retrofitting is an attractive proposition for most large or aging structures as it provides decision-makers the ability to improve upon key problem areas without having to consider large-scale reconstruction or demolition - saving on time, resources and costs."

She said, "Modern housebuilders and homeowners can look towards retrofitting, too, improving their footprints and putting money back in their pockets, as they seek to combat the significant rise in energy costs.”

Understanding retrofit

Investment in retrofit projects could have a seismic effect on the construction industry, acting as a catalyst

Investment in retrofit projects could have a seismic effect on the construction industry, acting as a catalyst to the economy and improving various areas of our building network. And while its proper retrofit can play an important role, consequences can arise when a project isn’t approached correctly.

Karen Trigg continues, “Naturally, modern technology developments and legislation changes will continue to drive product enhancements. Take door hardware, for example, a crucial component of a building’s fire safety, security, and everyday operation. There will always be a responsibility to ensure the hardware in older buildings remains up to standards and that we are meeting the latest in safety and sustainability regulations."

Door and the fire safety

She said, “As time passes, hardware experiences wear and damage and the replacement of aged components becomes necessary. And in some cases, new products will emerge as an improvement on previous applications. With that, an effective retrofit could significantly enhance the functionality of a door and the fire safety and security of a building - not to mention the environmental benefits associated with installing better, long-serving products."

Fire safety 

Karen Trigg adds, “Effective retrofit projects can safeguard the quality of our buildings in the future, making crucial improvements to cost, safety and functionality. Although, without a proper understanding of the subject, mistakes will readily undo the good work that many are aiming towards."

She said, "A poorly specified or incorrectly installed retrofit could prove costly in terms of money and time and even present a danger to the integrity of a building’s fire safety."

Professional guidance 

The first step of the retrofit installation is to ensure the selected hardware replacement is suitable for the application

Karen Trigg continues, “A retrofit must be completed consciously and professionally, with reliable replacements. Failing to do so could be a breach of the Regulatory Reform (Fire Safety) Order."

She further said, "Whether an environmental or safety-conscious choice, the first step of any retrofit installation is to ensure the selected hardware replacement is suitable for the application, and decision-makers must understand the reasons behind their choices or seek professional guidance."

UKCA and CE certifications

Karen Trigg adds, “For door hardware specifically, retrofit projects must also be compliant under UKCA and CE certifications and be fitted to the manufacturer’s instructions, by BS EN 1154."

She continues, "Decision makers can refer to the Code for Construction Product Information (CCPI) for clear, accurate, up-to-date and accessible product information in line with the Building Safety Bill’s regulatory framework known as the Golden Thread of Information."

Doors testing certification

Karen Trigg concludes, “While the benefits are clear, all retrofit projects must comply with the doors testing certification. Consequences often result from retrofits that are not properly thought out, especially when the selection of appropriate alternatives is flawed. Generally, to improve understanding of what is required, education on the subject must be developed further. Because with a long-term, large-scale strategy, retrofit projects could provide wide-reaching returns for all involved.”
