Today’s Internet does not offer any quality level beyond best effort for the majority of applications used by a private customer. In particular, this applies for wire-line or wireless access networks which currently constitute the bottleneck of the communication infrastructure. Following the principle of economic traffic management we propose a collaboration of user and network control in order...

Globally, a large proportion of building's energy is consumed to achieve thermal comfort, as promoting efficiency and environmental sustainability buildings an important global goal. Therefore, the new building regulations are geared explicitly toward energy-saving projects. However, there usually many competitive priorities, such maximizing use in office buildings, leading complex multi-object...

Abstract This paper presents an alternative workflow for thermal comfort prediction. By using the leverage of Data Science & AI in combination with power computational design, proposed methodology exploits extensive data provided by ASHRAE Global Thermal Comfort Database II to generate more customised prediction models. These models consider additional, often significant input parameters li...

The Universal Thermal Climate Index UTCI assesses the interaction of ambient temperature, wind, humidity and radiant fluxes on human physiology in outdoor environments on an equivalent temperature scale. It is based on the UTCI-Fiala model of human thermoregulation and thus also allows for thermal comfort prediction. Comparing UTCI predictions to thermal sensation votes recorded on the 7-unit A...

Clothing insulation is a key parameter to assess thermal comfort and one of the most difficult parameters estimate in field studies. The recent ASHRAE Global Thermal Comfort Database II contains large sample clothing addition wide range other contextual parameters. However, database does not provide details on whether included additional that provided by chairs for seated occupants. This may af...

This paper will outline a research project currently being undertaken at The University of Melbourne aimed at developing a dynamic model of architectural comfort. Much of the energy used in buildings goes to providing suitable levels of environmental provision – light, heat and air – for building occupants. In terms of thermal performance, the levels have been determined principally through res...

The role of ventilation in the housing stock is to provide fresh air and to dilute internally-generated pollutants in order to assure adequate indoor air quality. Energy is required to provide this ventilation service, either directly for moving the air or indirectly for conditioning the outdoor air for thermal comfort. Different kinds of ventilation systems have different energy requirements. ...

Most of the developing nations like Nigeria intend to develop in a sustainable manner. This development cannot be realized if refrigerated-based air conditioning systems that are characterized by high power requirement, high cost and with a negative influence on t he environment are used as a means of achieving thermal comfort in living spaces. Evaporative coolers are viable options of achievin...
