The performance based approach involves the assessment of three basic components comprising the likely fire behaviour, heat transfer to the structure and the structural response. The overall complexity of the design depends on the assumptions and methods adopted to predict each of the three design components.
• Review and examine the basic components of the fire extinguishment process
• Review the five basic classifications of fire and explain the various types of agents used to extinguish or control fires in these five classifications
• Examine in detail the variety of agents used for fire extinguishment and explain the application methods for each of these agents
• Identify and explain the benefits of using the latest technological advances in fire extinguishing agents such as compressed air foam and ultrafine water mist systems
Example of natural air ventilation using CFD modellingStephane Meteodyn
Urbawind is a CFD software dedicated to quantify the natural air ventilation of buildings.
Such tool is useful to design green buildings where wind is used to improve the indoor thermal comfort with cross ventilation.
Objective is to determine project improvements from indoor thermal comfort and energy saving points of view.
For example, for a site study of natural air ventilation induced by wind in urban places, you can obtain:
– Mapping of wind speed and pressure
– Assess the natural air ventilation thanks to the computation of the air exchange rate
– Optimise the positions of openings according to the micro climatology

Simulating the Performance of the Unique MicroLouvre™ for Low Energy Building...SimScale
SimScale teams up with Smartlouvre Technology Ltd. to demonstrate how simulation technology can be used to evaluate the performance of MicroLouvre, a woven mesh of paper-thin bronze louvres. This product is used externally on windows and building facades to block and absorb heat, and control glare. As the only one of its kind on the market, MicroLouvre provides an option for low energy building designers that improves the performance of glazing while still allowing for daylight and natural ventilation.
SimScale evaluated the performance of Microlouvre testing its structural properties against airflow, solar, and thermal data.

ABSTRACT: With the advancement of science in all fields, particularly the discovery of electricity and gas, that created urban installations, plumbing and power plants with urban life of the people, along with all the advantages and comfort to the human race, had also associated risks. Among these are fire hazards. That this incident alone caused losses of life and property also and it can be imagined that in accompany of earthquakes and fires what kinds of the tragedy occurs. In this article, it can be attempted that first, to introduce Plasco Building and its history to speak briefly to explain the reasons for the collapse of this old and massive structures.
SimScale teams up with Greenlite, a provider of regulatory and building analysis services, to explore how cloud-based CFD software can be used by engineers and architects to quickly and accurately calculate wind pressure coefficients for projects in the built environment. Importing simulation files into IES and thermal modeling tools gives designers an extra advantage to evaluate ventilation and possible overheating.
Assessment of the natural air ventilation of buildings in urban area with the...Stephane Meteodyn
Nowadays, a lot of energy is spent for air-conditioning in the cities for offices and private-housing. A good knowledge of the urban climatology around the buildings allows using the wind for natural air ventilation. A combined approach based on a Computational fluid dynamics code (CFD) that models the wind in urban environment and on air network tool was developed to assess quickly the natural ventilation of buildings in urban area. The aerodynamic tool is a CFD-Network software named "UrbaWind which performs calculation of the outdoor wind combined with a macroscopic network method for the evaluation of the mass flow rates through the openings. Results depend on the external wind conditions, taking into account the local wind climatology.
Giving the influence of the shape and the disposition of the buildings on the wind behaviors, CFD software solves the equations of fluid mechanics with a specific model which allows taking into account the urban environment effects such as vortexes, venturi or wise effects etc…. Finally, the software is able to compute the air mass flow rate inside each internal volume depending on the opening's behaviors attached to the wall building.
The mass flow rates across air inlets and openings, as well as the pressure fields on the building envelope are computed for every wind incidence, considering a wind reference velocity. The local climatology is introduced to deliver statistical data useful to assess the energy consumption and the thermal comfort (air exchange rate, indoor velocity).
Through many architectural and urban design projects, Meteodyn will introduce during this session the characteristics of the software UrbaWind and the results delivered to the design teams.

In the present study, the extended concept of exergy analysis has been applied to a building located in
New Delhi with a volume of 60 m3 and having a single-glazed window on the south facing wall .With this study
thermal energy and thermal exergy flow were investigated to calculate the total thermal energy and exergy in
and out from the building. This allows performing a complex exergy analysis of the building in both heating
and cooling cases. The calculations were carried out by using the developed mathematical model of building
and measured solar radiation data on horizontal and vertical wall surface. The thermal energy and thermal
exergy flows for a space of a typical residential building of natural ventilation system with different parametric
changes (i.e. wall thickness, roof thickness, window material properties, window dimensions, wall material
thermal conductivity ) have been modelled and compared from the reference case .

This presentation will introduce two sets of design considerations for the development of online information literacy instruction and show how these considerations were implemented in the construction and implementation of Loyola Marymount University's First Year Seminar information literacy tutorial. The first set of best practices focuses on the visual and technical elements of a tutorial including User Control, Visual and Information Clarity, Navigation, and Accessibility. The second set addresses "best practices" in online instructional design and pedagogy and includes categories for Embedding Communication, Incorporating Active Learning, and Designing Test Questions. In order to be broadly applicable, each set of design considerations is intentionally formatted so that it may serve as rubric for assessing any online tutorial and will be made available both online and as handout for presentation attendees. This presentation also identifies the most common types of active learning exercises observed within the online tutorial environment, allowing attendees to gather ideas for maximizing good design elements and embedding active learning components into their own online tutorials.
