Leading Manufacturers The Health and Safety Executive (HSE), the authority on workplace health and safety in the UK has indicated in the past that “an acceptable zone of thermal comfort for most people in the UK lies roughly between 13°C (56°F) and 30°C (86°F).” Today, the HSE states that “during work hours, the temperature in all workplaces inside buildings shall be reasonable.”
Not only is it important for employers to ensure that employees are comfortable in the workplace, numerous studies have revealed that employee productivity has increased at cool, well air-conditioned workplaces. A satisfactory comfort zone for employees can be achieved by maintaining temperatures of air-conditioning systems at 21°C–23°C. By doing this, employee productivity has improved during morning, afternoon, and evening periods by 18%, 1% to 15%, and 7% respectively. Arguably, statistics such as these indicate that worker productivity can be severely affected during hot, afternoon sessions where an office is not fully air-conditioned.
Why is having an AC so important to worker productivity?
To Reduce Errors
When temperatures at the work place are excessively high, employees tend to be less able to focus on detailed tasks, make more errors and are less patient with colleagues and customers. This is most apparent during the hours of 1 PM and 4 PM when temperatures reach their peak. By investing in air-conditioning, an employer can remedy this.
To Promote Higher Performance Levels
Lower temperatures reduce perspiration and the risk of dehydration. When employees are properly hydrated, their performance levels are considerably higher and the working environment is improved for all.
To Prevent Sick Building Syndrome
The NHS categorizes Sick Building Syndrome as one that causes symptoms such as headaches, dizziness, nausea, aches and pains, fatigue, etc. These symptoms can result from a poor quality internal environment—especially in buildings with inadequate air conditioning or ventilation. The impact of Sick Building Syndrome results in the lowering of overall employee productivity and placing strains on available medical resources.
To Help Reduce Allergies
A clean air conditioning system helps exclude external allergens such as pollen. An employer can reduce allergies by ensuring that their air-conditioning system is well maintained and air pollutants are eliminated.
To Promote Employer Responsibility
Employers have a responsibility and duty of care to provide safe and comfortable working conditions. Comfort is often found in a cool workplace. In workplaces that have a mandatory dress code such as a suit and tie, having an air-conditioned workplace is all the more important. In this way an employer can maintain a preferred dress code, whilst also providing employees with a suitable working environment.
To Encourage Employee Morale
Finally, when employees know that an employer has invested in their wellbeing, employee morale and motivation is automatically enhanced. Thus, as employee morale improves, employee productivity will also increase. This simple formula encourages enlightened employers to provide sufficient air conditioning. This could mean investing in a new air-conditioning system or investing in comprehensive maintenance services to ensure any existing air conditioning is working efficiently and cost-effectively. Either way, an employer has a direct role to play in employee productivity. Employers need to act to enhance their bottom line.
