Structural analysis of a buidling using Robot Structural Analysis

A) HVAC Systems:
HVAC systems are responsible for the regulation of heat, airflow, ventilation, and air conditioning of an entire building. You won’t see the machines when you enter the building but you will most certainly feel the effects of a comfortable and well-ventilated workplace. Here are some of the top reasons why business owners opt to have reliable HVAC systems in place for their office buildings. HVAC systems control the overall climate in the building. They also make the proper adjustments whenever we experience changes in outdoor temperature.
During the winter season, the HVAC systems (mainly the boilers or heaters) work to keep the indoor temperature at a comfortable level. In hotter times of the season, the HVAC systems regulate air temperature by providing the necessary cooling to keep the entire building comfortable. Having a comfortable office climate increases the level of productivity and increases morale amongst the workers and employees. If you let your people work in settings conducive for work, they will surely be motivated to perform better because they feel
good in their work environment. No employee will enjoy working in an office where it is freezing, or in an office where you frequently have to ignore your perspiration just to focus on your computer screen.
Having a proper HVAC system installed is guaranteed to make your employees happy, hence, giving you better work results in return.
HVAC systems not only regulate the temperature inside the building, they also improve the quality of air.
The quality of air pertains to humidity, and a typical HVAC system will reduce the amount of humidity in the air so your workers and employees can continue enjoying a cozy and pleasant atmosphere at work. Proper HVAC systems are a worthy investment for any business or building owner because it gives you energy savings. HVAC systems today are automated, which means you no longer have to manually adjust the temperature settings or the time settings of each machine.

4. Given that Why do we need to assess buildings/analyze while modeling elements? Does design affect modeling in anyways

Structural analysis is the process of calculating the forces, moments and deflections to which the members in a structure are to be subjected. There is a vast range of analysis tools offering speed, precision and economy of design. 3-D, FE modelling, bespoke portal frame, cellular beam or plate grider design software are now widely available. Modelling catenary actions, cold formed member performance or grillage analysis - all these are now commonplace for structures, where hand analysis is impossible. Increasingly sophisticated analysis methods continue to improve the accuracy with which the behaviour of structures can be predicted. To perform an accurate analysis a structural engineer must determine information such as structural loads, geometry, support conditions, and material properties. The results of such an analysis typically include support reactions, stresses and displacements. This information is then compared to criteria that indicate the conditions of failure. Advanced structural analysis may examine dynamic response, stability and non-linear behavior. There are three approaches to the analysis: the mechanics of materials approach (also known as strength of materials), the elasticity theory approach (which is actually a special case of the more general field of continuum mechanism), and the finite elements approach. The first two make use of analytical formulations which apply mostly simple linear elastic models, leading to closed-form solutions, and can often be solved by hand. The finite element approach is actually a numerical method for solving differential equations generated by theories of mechanics such as elasticity theory and strength of materials. However, the finite-element method depends heavily on the processing power of computers and is more applicable to structures of arbitrary size and complexity.

What is energy analysis and why do we need to consider it while modeling in Revit? How does the factor of sustainability improve the quality of your design

Perform energy analysis on the building design through all stages, from the earliest conceptual phase through detailed design, to ensure that you are constantly working towards the most energy efficient building possible. Energy simulation can help you analyze the movement of energy in, out, and through the rooms and volumes in a building model. This information can help designers make better informed, cost-effective decisions that improve the performance and reduce the environmental impact of buildings.Whole building energy simulation measures expected energy use (fuel and electricity) based on the building's geometry, climate, building type, envelope properties, and active systems (HVAC & Lighting). It takes into account the interdependencies of the building as a whole system. Use Energy Analysis to perform energy simulation for conceptual forms and detailed architectural models created in Revit. Use the simulation results to understand building energy use. Then iterate the designs to improve their sustainability ratings.The energy model created from the Revit building model can be displayed in Revit, so you can view and validate the energy model used for analysis. The energy model can also be exported to third-party applications for further analysis in a variety of common formats: gbXML, DOE2, and EnergyPlus. Sustainable design deals with the philosophy of having built and designed objects, buildings, environments and services that conforms with the many principles of ecological sustainability. This includes maintaining change in a homeostatic environment where the use of resources, inclination of investments, and the direction of development are balanced and meet the current and future needs of humanity. Simply put, sustainable design represents development that not only meets the needs of the present but does so without compromising the ability of future generations to meet their own needs. Ways to approach sustainable design include utilizing sustainable chemical engineering, responsible resource management, and holistic environmental protection.
