Keeping cool – a more sustainable approach to air conditioning
by Martin Fahey ~ Head of Sustainability
As the weather blows hot and cold, Martin Fahey explores how important it is to control energy use in buildings.
As the UK experiences its longest heat wave since 1976, inevitably the environmental impact of increased air conditioning and other cooling requirements have come under the spotlight, particularly in the commercial sector.
This may have left you feeling that the debate on the merits of air conditioning has focused rather too much on the negative impact of increasing energy use, rather than the sometimes lifesaving and performance benefits of keeping people cooler during such incredibly hot spells.
More positively, this renewed engagement and focus on the industry provides us all with an opportunity to reassess, innovate and take greater control for a more sustainable approach to our air conditioning solutions.
We can’t control the weather, so it’s time to control what we can – the ‘controllables’.
Efficiency first
With budgets becoming tighter and pressures mounting to become more energy efficient, operators of commercial buildings are already adopting the mindset that the priority is to reduce energy use and be the most efficient they can be from the outset.
Whether it’s manufacturers, installers or contractors, we should all be adopting an energy hierarchy approach; a sustainable approach whereby you first aim to reduce your need to consume energy, then look at how you can deliver the buildings requirements efficiently with better solutions, and finally how you can deploy renewable energy sources at a building scale.
Whatever the system, it will become increasingly important to ensure that the way it is designed, specified, installed and operated, is done in the most efficient way possible.
Modern commercial buildings today will often need some level of cooling. Large amounts of energy are required to both heat or cool buildings in the UK, but the benefits of getting it right can contribute to a healthier and more productive bottom line for the business.
The right choices need to be made to find a system that can deliver the comfort needed in the most energy efficient way possible.
Providing thermal comfort – not a nice to have but a necessity
In today’s modern working world, it becomes hard to escape the need to consume energy, particularly when we look at modern working spaces – there needs to be a balance of cooling alongside heating and ventilation.
A business that provides an ideal working environment, or even a variable one to suit different employees, can certainly reap the rewards.
It can also help them meet building standards such as the WELL Building Standard, that provides a holistic formula promoting better health and well-being in workplaces.
According to a study conducted on the impact of heat on office productivity, employees experience a 2% decrease in productivity for every 1°C above 25°C.
Thermal comfort – a condition of the mind that expresses satisfaction with the environment, i.e. when someone is not feeling either too hot or too cold – becomes vital when you consider the productivity and wellbeing benefits of employees in commercial buildings across the globe.
When you consider the fact that 90% of business operating costs are staff related, improving the health, wellbeing and productivity of this ‘asset’ can only help improve your overall business.
When you take into account the fact that we spend just 5% of our day outside, you start to understand how important it is for businesses to provide employees with an environment in which they feel comfortable and can therefore produce their best work. Part of this is providing the right levels of cooling into a building.
In some instances, cooling within the building is so vital, it can be considered life critical.
For example, in the healthcare industry, hospitals and medical centres have to rely on efficient cooling systems to ensure a constant temperature is maintained for its patients and medical equipment.
It’s important that we maintain a balanced perspective between the impact and benefits of cooling environments and recognise that there often, there is a fundamentally critical need for it.
