Do You Know Of A Better Method To Manage Room Temperature?
Press release: 29 July, 2021: Many office owners complain of being too hot and cold. But, the latest technology may help to reduce the discomfort. In any home, office, or shared space, there's always someone who's too cold, or too hot, and a person who doesn't understand the fuss around the thermostat really is about.
Although the factors that define a comfortable temperature are all very human, buildings typically utilize static temperatures -- a range between 20 and 23.8 degrees Celsius (68.5 to 75 degrees Fahrenheit) in the winter months and 23.8 to 26.9 (75 to 80.5) in summer--to program and run office heating, cooling, and air conditioning (HVAC) systems. Many people feel hot and cold, no matter the amount of energy cooling and heating systems consume to provide comfortable temperatures.
Control of an Artificial Environment
The HVAC system is responsible for about 50 percent of total energy required to run residential or commercial buildings in the United States. The 22 percent national energy consumption in the United States is attributed to commercial structures. But this huge energy consumption is rarely a result of the goal of universal happiness with a building's room temperature app.
HVAC systems are programmed so they will always supply an established amount of cooling and heating. They do not adapt to human preferences or data. These systems don't adjust for variables such as direct sunlight heat, so temperatures in the air may fluctuate and people may experience different thermal sensations.
Health, Performance, and Comfort
It would be better for people to feel comfortable if building HVAC systems could respond in real-time to their various levels of comfort and changes throughout the day. The environment and especially the thermal comfort levels have a direct impact on one's health, well-being and performance.
The relationship could have profound, long-lasting effects, especially when you consider that Americans and Canadians spend on average 90 percent of their summers indoors and 97 percent of their winter indoors. The performance of employees in offices can be greatly affected by the perception of the office's thermal conditions. An employee who is comfortable will be more content with their surroundings which could lead to lesser complaints, less absenteeism in addition to a higher productivity and a higher level of motivation.
However, a poor thermal conditions can result in lower job satisfaction, decreased job performance, lower self-estimated productivity, and problems in concentration. Temperatures rising in the room may trigger symptoms of sick building syndrome. which is a sensation of illness that can affect the health of the occupant of a building. This includes irritations to the eyes, throat and nose. It may result in an increase in mental strain to perform cognitive tasks.
Though factors like motivation could help to offset the negative effects of a warm environment on task performance, it can still result in a decrease in an individual's capacity to use their total neural resources. This continuous mental overload could have an adverse effect on overall health in the long run. The simplest way to create a positive workplace environment is to regulate the temperature using the HVAC system.
Different Comfort Levels
Most often, the owners of buildings discover the quality of their cooling and heating systems are operating by asking how comfortable the occupants are. Everyone has an ideal temperature that may change at any given moment, based on any number of factors, including the gender, age as well as their level of physical activity and clothing as well as current stress level. This creates a challenge in determining the most comfortable temperature for everyone and how to regulate it.
Povl Ole Fanger (Danish environmental engineer, specialist in thermal comfort) invented the PMV model. It assesses thermal comfort using four variables from the environment (air temperature, mean radiative temperature, air velocity, and relative humidity) in addition to two human factors (metabolic rates and insulation for clothing). The PMV model has been adopted as an international standard and is used to assess occupant indoor thermal comfort on a seven-point sensation scale, with -3 representing cold, 0 being neutral, and +3 being hot.
