"What is a Comfortable house?"

“Indoor environmental conditions acceptable to human occupants with regard to comfort and health. Includes thermal comfort, indoor air quality, sound and vibration, and non-ionizing electromagnetic radiation (including visible light).”

“The vast majority of buildings today suffer from inadequate performance, such as excessive energy
consumption, thermal comfort issues, and insufficient daylighting. These deficiencies are often the result of an inability of the design team to consider a wide variety of design options for all these criteria in an integrated and systematic way.”

“The answer is that for most people, most of the time, the range of conditions that we’re comfortable in is pretty narrow. If the temperature’s between 70 and 80 degrees Fahrenheit and the relative humidity (RH) between 30% and 70%, we’re more or less comfortable.”

“With thermal neutrality as a goal, an ideal building would be one that you wouldn’t notice or feel, one that would allow the body to exist in a healthy state and at a comfortable temperature, or even one which would improve your sense of wellbeing upon entering.”

“Two conditions must be fulfilled to maintain thermal comfort. One is that the actual combination of skin temperature and the body’s core temperature provide a sensation of thermal neutrality. The second is the fulfillment of the body’s energy balance: the heat produced by the metabolism should be equal to the amount of heat lost from the body. The metabolism is the energy released by oxidation processes in the human body, which depends on the muscular activity.”
