Adaptive thermal comfort and its application in mixed mode buildings: The case of a hot-summer and cold-winter climate in China
… behaviour leads to an increase in comfort temperature, which is termed adaptive increment in this study. Apart from adaptive increments, this method also determines a baseline thermal comfort temperature (the thermal comfort temperature without adaptations) and a correction factor that …

The endangered bank cormorant Phalacrocorax neglectus: the heat is on : understanding the effect of climate change and associated environmental variable changes on the breeding biology and population dynamics of the bank cormorant in the W. C., S. A
… Western Cape, South Africa. High environmental temperatures resulting in heat stress and storms with associated extreme environmental variables was predicted to cause breeding failures, decreasing breeding success. As a result, climate change can also affect long-term trends in the adult …

The Thermal Ecology of Sceloporus occidentalis
<p>With temperatures rising globally, assessing the possible impacts of the changing climate becomes more and more urgent. Ectotherms are excellent indicators of potential climatic ramifications on biodiversity because of their heavy reliance on the environment for their thermoregulation. Studies …

New technologies for energy savings in the refurbishment of existing buildings.
… solar energy continuously, reducing the internal temperature fluctuation and improving the thermal comfort. The most used heat storage materials for building application are the Phase Change Materials (PCMs) which store solar energy during the day and release it during the night. The aim of this …

Influence of the thermal environment on forest cover selection and activity of moose in summer
… were entered into a model that simulated the operative temperature (Te) experienced by a moose. 'Hot' conditions existed when Te in the open (Teopen) exceeded the upper limit of the upper critical temperature (UCT) range of moose (Te >29.5 °C). 'Cool' conditions existed when Teopen was below …
