The office environment
The physical office environment and its location has an impact on the health, well-being and productivity of employees.
The office environment is made up of several factors, which can be measured or evaluated in numerous ways.
Occupants health outcomes
Physical office factors can influence the health of occupiers. This can be measured or evaluated with some of the below indicators:
- Eye strain/damage
- Skin irritation
- Seasonal Affective Disorder
- Asthma and breathing disorders
- Stress and depression
- Other physical complaints, like back ache
- Other serious disorders, including cardio-vascular
Occupants well-being and perception outcomes
An occupant’s sense of wellbeing is also comprised of their perception of numerous factors, including how productive they think they are. We can use the below measures to gauge well-being in the office environment:
- Perceived physical health
- Perceived psychological health
- Perceived productivity
- Perceived office environment
- Perceived organisational culture
Organisational and financial outcomes
The office environment can have a direct impact on occupant productivity, in which health and wellbeing is often a compounding factor.
This outcome for the organisation can be measured or evaluated in some of the following ways, all of which have financial implications for the employer:
- Staff turnover/retention
- Medical costs
- Medical complaints
- Physical complaints
- Task efficiency and deadlines met
What do we get back in return?
Maximised Return on Investment, the financial evaluation based on life cycle costing that includes capital and operational, for all strategies designed to benefit occupants and improve productivity.
- Lower employment cost per employee, including reduced absence costs
- Higher staff retention and reduced costs of staff turn-over
- Greater ease of high quality recruitment, lowering recruitment costs and adding value
- Greater productivity of staff on core tasks
- Optimised green building ratings resulting in higher value/lower risk/ improved reputation
- Reduced occupant complaints via ‘Help Desk’ and other similar feed-back systems, leading to reduced costs
- Increased company revenue
Effects on performance in offices
The numbers don't lie
- Every 1°C reduction in overheating increases the employee’s performance by 3.6%.
- Every 1 litre per second per person (l/s/p) increase in ventilation increases the employee’s performance by 0.8%.
- Every 100 lux increases in lighting level increases the employee’s performance by 0.8%.
- On average, better daylight is connected with a 10% increase in performance.
- For every 1 dB decrease in excess noise, performance is improved by 0.3%.
Watch: Thermal and indoor air quality effects on the performance of office work
By David P. Wyon
Webinar recording from the Swegon Air Academy, 2015.
In this video you will find information on thermal and air quality effects on the performance of office work.
It summarises the following findings:
- Workrate is 8% lower at 27°C (slightly warmer) vs. 20°C (cool) when clothed for 25°C (neutral)
- Bioeffluents and emissions reduce workrate
- Relative humidity below 20% affects eyes & reduces workrate
- Effects of temperature, pollutants and noise accumulate
- Individual choice improves performance
