Abstract

Traditional tools in the domains of thermal design and control of building systems usually rely on a deterministic approach. Building systems, on the other hand, are strongly influenced by meteorological variables, which obviousy are characterized by a stochastic nature. Due to this mismatch, traditional tools can neither evaluated properly the fluctuations of the solar and heat load intensities for design puroposes, nor anticipate their stochastic behavior to optimize the thermal control of building systems. The aim of this research is the application of stochastic methods to overcome this difficulty.

Stochastic process

In probability theory and related fields, a stochastic (stəˈkæstɪk) or random process is a mathematical object usually defined as a sequence of random variables, where the index of the sequence has the interpretation of time. Stochastic processes are widely used as mathematical models of systems and phenomena that appear to vary in a random manner. Examples include the growth of a bacterial population, an electrical current fluctuating due to thermal noise, or the movement of a gas molecule.

Thermal comfort

Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation (ANSI/ASHRAE Standard 55). The human body can be viewed as a heat engine where food is the input energy. The human body will release excess heat into the environment, so the body can continue to operate. The heat transfer is proportional to temperature difference. In cold environments, the body loses more heat to the environment and in hot environments the body does not release enough heat.

Stochastic

Stochastic (stəˈkæstɪk; ) refers to the property of being well described by a random probability distribution. Although stochasticity and randomness are distinct in that the former refers to a modeling approach and the latter refers to phenomena themselves, these two terms are often used synonymously. Furthermore, in probability theory, the formal concept of a stochastic process is also referred to as a random process.
