Is There A Better Way To Regulate The Temperature Of A Room?

Press release: 29 July, 2021: Office occupants often complain of being too hot or cold, but the latest applications of technology could help defuse the war on thermostats. There will always be someone in an office or home space that is either too hot, cold, or too hot.

Although the temperature of the building is determined by a variety of variables, they rely on static temperatures (between 20 to 23.8 degrees Celsius (65 to 75 degrees Fahrenheit in winter) and 23.8 to 26.9 in summer) to regulate and program the office heating, ventilation and air conditioning (HVAC). People often feel too hot and too cold, no matter the amount of energy cooling and heating systems require to offer comfort.

Regulation of an Artificial Environment

In the United States and worldwide, HVAC systems comprise around 50 percent of all energy needed to run commercial and residential buildings. Commercial buildings alone make up 22 percent of United States national energy consumption. However, this huge energy consumption rarely achieves its goal of universal comfort with the building's temperature.

HVAC systems are designed so they will always supply an established amount of cooling and heating. They do not adapt to individual preferences or information. They don't take into account factors like direct sunlight heat, so the temperature of the air can change and people can feel different sensations of heat.

Health, Performance and Comfort

Construction of HVAC systems that are able to react instantly to the changing comfort levels and fluctuations throughout the day will allow them to feel more comfortable. A person's level of satisfaction with their environment and more specifically, their levels of comfort, have an immediate impact on their health, wellbeing and overall performance.

Furthermore, considering that individuals in the United States and Canada spend an average of 90 percent of their time inside in the summer and an average of 97 percent in the winter months, this connection could have profound, long-lasting impacts. The environment's thermal conditions can have a significant influence on the performance of employees when working in an office that is indoor. A person who feels at ease in their environment will likely to experience lower complaints, less absenteeism, increased productivity, and a higher level of motivation.

But, a cold atmosphere can result in less satisfaction with work, lower performance at work, a decrease in self-estimated performance, as well as difficulties in concentration. High room temperatures may result in an increase in complaints of the symptoms of sick building syndrome (a feeling of ill health which affects people living in of a structure, such as eyes, noses and throat irritation) as well as increased mental load to perform cognitive tasks.

Even though factors such as motivation may offset a negative thermal environment's effect on performance, managing that thermal stress can still deplete a person's overall neural resources. This continuous mental overload could result in a negative effect on overall health in the long-term. Monitoring the temperature of the environment via the HVAC system by adjusting thermostat set points is among the most effective ways to achieve an optimal working setting.

Different Comfort Levels

Most often, building owners find out how well their heating and cooling systems are operating by asking how comfy the residents are. Everyone has a preferred temperature that can vary in accordance with gender, age, activity level as well as their clothing and stress levels. The different levels of comfort create an issue that is complex: what is the most comfortable thermal environment for the greatest number of people, and then how to regulate it.

Povl Ole Fanger (Danish environmental engineer, expert in thermal comfort) invented the PMV model. It assesses thermal comfort using four environmental variables (air temperature, mean radiative temperature, air velocity and relative humidity) and two human aspects (metabolic rates and the insulation of clothing). The PMV model has been adopted as an international standard, and it is used to assess occupant indoor thermal comfort using a seven-point temperature scale, where -3 is cold, 0 neutral and +3 being hot.
