In order to achieve a Danish energy supply based on 100% renewable energy from combinations of wind, biomass, wave and solar power in 2050 and to cover 50% of the Danish electricity consumption by wind power in 2020, it requires more renewable energy in buildings and industries (e.g. cold stores, greenhouses, etc.), and to coordinate the management of large numbers of distributed energy resourc...

The tall building is the most dominating symbol of the cities and a human made marvel that defies gravity by reaching to clouds. The development of high strength concrete, higher grade steel, new construction techniques and advanced computational technique has resulted in the emergence of a new generation of tall structures that are flexible, low in damping, slender and light in weight. These t...

In our paper, we propose a solution for a robotic sailboat which is adapted to long travel across the ocean. We tried to be as innovative as possible and stray out of the classical designs. In fact, robots often have different shapes from vehicles for mankind since first of all there are no human on board which means less constraints with regards to security, ergonomy or comfort. In this paper ...

This paper presents the urban wind ventilation mapping from building frontal area index on the example of urbanised city, Hong Kong. The calculations of frontal area index for each uniform 100m grid cell are based on three dimensional building databases at eight different wind directions. The frontal area index were then correlated with land use classification map, and the results indicate that...

Urban ventilation plays an important role in regulating city climate and air quality. A numerical study was conducted to explore the ventilation effectiveness on the microclimate and pollutant removal in the urban street canyon based on the rebuilt Southern New Town region in Nanjing, China. The RNG k− ε turbulence model in the computational fluid dynamics (CFD) was employed to study the street...

There is a need to shield from the wind improve pedestrian comfort in urban environments. Perforated windbreaks, such as fences, vegetation or textile nets, have proven be an efficient solution, whereas knitted textiles not yet been explored. The purpose of this study was evaluate capacity windbreaks reduce velocities, inform further research and promote wider architectural applications. Five c...

The influence of the surrounding building topography Datong-Xi?an high-speed railway foundation on wind environment and thermal comfort is studied, especially outdoor indoor air-flow organization buildings are analyzed numerically, terrain temperature wind?s speed distribution systematically evaluated. results show that roadbed has a significant effect site, affecting natural ventilation in sum...

We investigate strategic information transmission with communication error, or noise. Our main finding is that adding noise can improve welfare. With quadratic preferences and a uniform type distribution, welfare can be raised for almost every bias level by introducing a sufficiently small amount of noise. Furthermore, there exists a level of noise that makes it possible to achieve the best pay...

The Universal Thermal Climate Index (UTCI) addresses these shortcomings by using an advanced thermo-physiological model. The aim of this study was to investigate and prepare zoning of thermal comfort condition using UTCI. Meteorological data including temperature, wind speed, cloudiness and relative humidity were obtained on a daily time scale from 10 synoptic stations during (2004-2013) period...
