Problems such as natural ventilation, pollutant dispersion, changes in wind environments, and urban heat islands are gaining increasing prominence in both public concern and research. In response urban microclimate modelling researchers are continually striving to develop new strategies to rapidly and inexpensively generate more accurate results. Numerical modelling is a common way to address t...

The microclimate of a naturally ventilated plastic house was simulated for 23 days using the Gembloux Greenhouse Dynamic Model (GGDM). Improved calculations of natural ventilation #ux and stomatal resistance of vegetation were introduced, based on experimental equations from previous research. A linear non-dimensional ventilation function was developed and compared with those obtained by other ...

We measured microclimate, field metabolic rates (FMRs), water flux, and activity patterns of telemetered box turtles (Terrapene carolina) in South Carolina from September 1987 to October 1988. Turtles were inactive for most of the winter and were active only sporadically during the rest of the year. Using the doubly labeled water method, we found that water flux averaged 8.8, 18.9, and 26.4 mL ...

M icroclimate is the suite of climatic conditions measured in localized areas near the earth's surface (Geiger 1965). These environmental variables, which include temperature, light, wind speed, and moisture, have been critical throughout human history, providing meaningful indicators for habitat selection and other activities. For example, for 2600 years the Chinese have used localized seasona...

Since 2006, year-round measurements of climatic parameters of characteristic ecosystems of James Ross Island, such as (1) coastal vegetation oases, (2) volcanic mesas have been performed by automatic weather stations. Simultaneously, prospection, classification and mapping of vegetation cover have been made annually within the period of Czech Antarctic expeditions lasting from January to March....

Results from three years of continuous monitoring of environmental conditions using a wireless sensor platform installed at The Cloisters, the medieval branch of the New York Metropolitan Museum of Art, are presented. The platform comprises more than 200 sensors that were distributed in five galleries to assess temperature and air flow and to quantify microclimate changes using physics-based an...

of gaseous pollutants on paintings installed in microclimate frames (mc-frames), and some examples of modelling results, is presented. The model can be used to study how basic design properties of microclimate frames, such as their air exchange rate, their volume and/or the inclusion of absorbers can affect the pollution fluxes to paintings inside the frames. The modelling indicated that a magn...

The microclimate environment in nursery pig house is important. In this paper an environmental control system based on PLCC for piggery was designed. In order to adjust the local microclimate environment in precise, wireless network equipments like sensors and electronic hot plates were constructed. Management operation can extend from remote user into the piggery to realize the exchange of inf...

Natural ventilation has played an important role for many low energy-building designs. It has been also noticed as a essential subject to persistently bring the fresh cool air from the outside into a building. This study carried out the computational fluid dynamics (CFD)-based simulations to examine the natural ventilation development of a work area in a public building. The simulated results c...
