We can’t control the weather, so it’s time to control what we can - the ‘controllables’.
The most efficient unit of energy is the one you don’t use
Adopt a sustainable approach to energy consumption
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.
Energy efficient air con in commercial buildings
We have established that air conditioning plays a key role in commercial buildings and those involved in the decisions of which systems install have a responsibility to ensure their choice represents the most energy efficient one possible.
However, manufacturers also have a duty to ensure that the solutions on offer, are as sustainable and efficiently produced as possible.
This could be represented by a hybrid system where traditional refrigeration-based systems work with water as a delivery medium, to lower the overall environmental impact of the system or selecting R32 as a refrigerant which has a lower global warming potential to many of its alternatives.
Use controls to reduce energy use
Once installed, understanding the wide range of controls available with your system can also help reduce wasted energy. Many controls give companies the opportunity to monitor and control their air conditioning across a room, building or an entire network from a single PC or device.
Many building operators are simply using these controls as a timer, which is fine for some, particularly in smaller buildings with a constant number of employees. However, the range of functions goes far beyond this.
For example, if a meeting room is empty, modern devices have the ability to automatically recognise this and lower/switch off the air conditioning to conserve energy. They can also be used to monitor energy usage, spotting trends and anomalies to make changes to help further reduce energy costs.
We can’t control the weather, but there are factors that we can control, and we need to recognise this opportunity to do so.
The topic of energy efficiency isn’t going away and if anything, it will move closer to the top of the agenda as pressure, quite rightly, mounts to find ways to mitigate the effects of climate change.
Great strides have already been made in the industry. However, there’s always the opportunity for new innovations to help us make smarter decisions and find that balance creating the perfect conditions for a productive workforce and reducing energy requirements and environmental impact.
