Abstract
Thermal comfort is a topic that for the last century has interested designers and researchers. European and International standards have given guidelines for assessment of thermal comfort in typical indoor environments for long occupancy, however the transitory spaces and semi-external spaces have not been addressed.
Available literature was reviewed and summarize to find appropriate methods for assessment of thermal comfort in transitory and semi-external spaces. A methodology was developed that uses Predicted Mean Vote, Adaptive Model and Universal Thermal Climate Index for assessment of thermal comfort and informs designers on the comfort limits for different environmental parameters. The method uses Predicted Mean Vote and adaptive... (More)

A methodology was developed that uses Predicted Mean Vote, Adaptive Model and Universal Thermal Climate Index for assessment of thermal comfort and informs designers on the comfort limits for different environmental parameters. The method uses Predicted Mean Vote and adaptive comfort models for defining comfort boundaries for indoor spaces with specified activity and clothing levels. Standard recommended comfort models (EN 15251; ISO 7730) are used, as well as an extended adaptive model for transitory spaces. For semi-external spaces the Universal Thermal Climate Index was used.
Through a case study it was demonstrated that the method is valuable for building designers in understanding thermal comfort and the effect of different environmental parameters as air temperature, mean radiant temperature, air velocity and relative humidity. The method can help designers in finding appropriate measures for avoiding thermal discomfort.
Further development is necessary to include standard recommendations for local discomfort in the assessment of design solutions. (Less)

“Examination of adaptive thermal comfort models for appropriate assessment of thermal comfort in transitory and semi-external spaces” by Medina Deliahmedova
In recent years attention has been focused on energy efficiency in buildings and this is often in conflict with the comfort conditions, if appropriate design is not considered from the beginning. Defining the comfortable conditions in early stages of the building planning is essential for achieving good indoor environment as well as energy efficiency. But what is thermal comfort and how to define the limits of comfort for different environmental parameters such as air temperature, mean radiant temperature, air velocity and relative humidity?

In recent years attention has been focused on energy efficiency in buildings and this is often in conflict with the comfort conditions, if appropriate design is not considered from the beginning. Defining the comfortable conditions in early stages of the building planning is essential for achieving good indoor environment as well as energy efficiency. But what is thermal comfort and how to define the limits of comfort for different environmental parameters such as air temperature, mean radiant temperature, air velocity and relative humidity? This thesis focuses on examining thermal comfort models and implementing them in a tool that informs designers on comfort limits for the different environmental parameters and allows for design assessment. The tool includes Predicted Mean Vote and adaptive comfort models for defining comfort boundaries for indoor spaces with specified activity and clothing levels. Standard recommended comfort models (EN 15251; ISO 7730) are used, as well as an extended adaptive model for transitory spaces. For semi-external spaces was used a recently developed thermal index called Universal Thermal Climate Index.
By using a case study of an indoor zoo project, it is demonstrated that the tool is valuable for building designers in understanding thermal comfort and the effect of different environmental parameters as air temperature, mean radiant temperature, air velocity and relative humidity. The tool can help designers in finding appropriate measures for avoiding thermal discomfort, by defining the limits for the environmental parameters. For example, appropriate cooling and heating set points can be found for considered air velocity; need for use of shading devises can be defined by exploring the limits of mean radian temperature. The tool is flexible in a way that it allows designers to dynamically change all environmental parameters, explore their limits and find combinations that provide comfort conditions. The tool is also valuable as it uses standard recommendations for comfort limits as described in EN 15251 and ISO 7730. (Less)
