This research investigates the effect of urban design factors on summertime urban heat island (UHI) intensity. Ten high-rise residential quarters in the inner city of Shanghai were empirically investigated during mid July to mid August in 2008. On-site design variables were developed to quantify the thermal impacts from density, building layout and greenery. The design variables that weremeasur...

The layout of the ventilation system of an operating theatre is a crucial matter, because numerous infections occurring in hospitals today are directly related to air flow induced by the air conditioning system. The interactive fluid simulator developed by our group allows the engineer responsible for the HVAC design of an operating theatre to interactively determine the optimum shape and posit...

Building energy analysis tools are available in many forms that provide the ability to address a broad spectrum of energy-related issues in various combinations. Often these tools operate in isolation from one another, making it difficult to evaluate the interactions between related phenomena and interacting systems, forcing oversimplified assumptions to be made about various phenomena that cou...

The utilization of urban underground space is a strategic choice to solve land shortage, traffic congestion and environmental pollution. corridor serves as both commercial entertainment spaces. Proper natural ventilation system believed combine the advantages good indoor air environment high energy efficiency. In present study, field experiments numerical simulation are performed compare perfor...

Optimisation tools which determine the best layout for access and haulage in an underground mine address an important and difficult mine design problem. The complexity of the problem can be compared to the task of optimising the final pit design in an open pit, together with the pit haul roads required. The strategic design of an underground mine layout must address the location of haulage shaf...

modeling of relationship between ventilation rate of buildings and sick building syndrome symptoms hosseinpoor s , gholamiborujeni f *, mohammadian y received: 22 aug, 2013 accepted: 23 oct , 2013 abstract background & aims: indoor air pollution with microbilal, chemical and physical pollutants lead to sick building syndrome (sbs). suitable ventilation of buildings, is one of the best methods t...

Good natural ventilation can improve the comfort of campus dormitories and effectively avoid pollution caused by particle accumulation. Parametric design address feedback connection between building performance analysis design. This study employs an architect-friendly digital method based on Rhino/Grasshopper parametric platform. It takes in cold region as a case, using parameterized tools, suc...

Pumped storage power station is an economic and reliable means of peak load regulation for networks. The temperature humidity control are complicated due to the huge amount heat moisture emission in main plant. This paper investigates operating condition three different ventilation cases a five-storey underground pumped station. A full-scale model plant was built numerical simulation. Three wer...

This study investigates the experience of health and medical personnel in hospital operating rooms to evaluate effectiveness activities ventilation conditions hospitals. was designed as a qualitative research based on Heidegger's Hermeneutic Phenomenology Approach. The method carried out working room (OR) observers. data were collected using an open unstructured interview form. form includes it...
