CFD and wind-tunnel analysis of outdoor ventilation in a real compact heterogeneous urban area: Evaluation using “air delay”
N Nestoras Antoniou,N Nestoras Antoniou,Hamid Montazeri,Hamid Montazeri,Hans Wigö,Marina Neophytou,Bje Bert Blocken,Bje Bert Blocken,Mats Sandberg +8 more
TL;DR: In this paper, the authors investigated outdoor urban ventilation in a real complex urban area by introducing a new ventilation indicator, the "air delay", and performed computational fluid dynamics (CFD) simulations.

CFD simulation of urban microclimate: Validation using high-resolution field measurements.
TL;DR: In this study, CFD simulations of urban microclimate are performed for a dense highly heterogeneous district in Nicosia, Cyprus and validated using a high-resolution dataset of on-site measurements of air temperature, wind speed and surface temperature conducted for the same district area.
Journal ArticleDOI
The effect of soil sealing on the urban heat island phenomenon
TL;DR: In this article, a case study was developed for the case of Nicosia, a city that experiences high urban heat island intensities due to its geographical location and its continuous urban growth.

A holistic approach to assess the exploitation of renewable energy sources for design interventions in the early design phases
TL;DR: In this article, the authors present a holistic approach applied to assess the exploitation of renewable energy sources for design interventions in the early design phases in a consolidated urban environment, which is tested on two existing residential building blocks in a case study district in Bolzano (Italy).
Journal ArticleDOI
Non-isothermal flow between heated building models
TL;DR: In this article, the effect of buoyancy by measuring at forced to mixed convection flow regimes with Richardson (Ri) numbers ranging from 0 to 1.09 was investigated, in which a finite-length street canyon with heated surfaces was considered.

Simulation of surface urban heat islands under `ideal' conditions at night part 2: Diagnosis of causation
TL;DR: In this article, a simple energy balance model which simulates the thermal regime of urban and rural surfaces under calm, cloudless conditions at night is used to assess the relative importance of the commonly stated causes of urban heat islands.
Journal ArticleDOI
A study of the thermal performance of reflective coatings for the urban environment
TL;DR: In this paper, the effect of reflective coatings on lowering surface temperatures of buildings and other surfaces of the urban environment, and thus test their suitability to lower ambient temperatures and fight the heat island effect was investigated.
Policies to Reduce Heat Islands: Magnitudes of Benefits and Incentives to Achieve Them
TL;DR: In this paper, the authors proposed a strategy of lighter-colored reroofs and resurfaced pavements, and shade trees, which can directly lower annual air conditioning bills in Los Angeles (LA) by about $100 million (M), cool the air in the LA Basin (thereby saving indirectly $70M more in air conditioning), and reduce smog exceedance by about 10%, worth another $360M, for a total savings of about $0.5 billion per year.

Progress in urban dispersion studies
E. Batchvarova,Sven-Erik Gryning +1 more
TL;DR: In this article, the authors address recent achievements in better representation of the urban area structure in meteorology and dispersion parameterisations and discuss the setup and main outcome of several recent dispersion experiments in urban areas and their use in model validation.
