HVAC STANDS FOR

H-HEATING

V-VENTILATION

AC-AIR CONDITIONING

HVAC is a system which is used to maintain the temperature ,circulate enough air and lighting to the building with the help of some units

HVAC is the important part of the building where safe and healthy conditions are regulated with respect to temperature and humidity ,using fresh air from out doors

Ventilatilating or ventilation is a process of exchanging or replacing air in any space to provide high indoor air quality.It also remove unpleasent smelland excessive moisture

Air conditioning system provides cooling and humidity control for all parts of a building ,Air conditioning and refregiration are provided through the removal of heat .

HVAC essential to modeling of building:

whenever we are working on a team project or in a real world we will e given a design requirements of HVAC

when we are working on a coordinate project it is necessary to have a basic knowledge of HVAC system which makes us to coordinate with a better judgement .

While we are modelling it is necessary to look after the comforts ,energy saving of the building .HVAC system are used fo cintrolling the overall climate in the building

To provide optimum lighting and aircirculation and control the temperature and humidity with in the building space .HVAC improves air quality in the building helping make it appropriate for human breathing .it reduces humidity so occupants can enjoy the better atmosphere.This is especially useful for buildings or underground spaces where ventilation is limited.

For sizing of systems .To check the mechanical performance of the ducts .to design them as per space required as per the space alloted to building provisons. This HVAC system place and an important role in the building modeling and they are essential .

These are the following steps to be followed to use add-ins tab to load plug-ins for robot structural analysis .

• Open the revit software , go to the Analysis tab and check whether the robot structural analysis is enableed in our software or not
• If not available we need to download if from autodesk store
• click on the shopping cart icon which is available at top right corner, the autodesk store will ne opened .
• In search tab enter the structural analysis tool kit, the software will apper
• select the respective version and click install
• The ROBOT STRUCTURAL get installed and will reflected in to our Revit software in analyse tab.

We need to analyse the structure while modeling because the structure is the important component of the building . The main fuction of stucture is to bear all the loads and should be servicible through out the life span.

Structural analysis is nothing but determination of the loads on the physical structure and their components. Structures are generally subjected to different types of loads like dead loads, live loads, wind loads and sesmic load. The structure should capable to with stand all loads combinations. Strucutral aanalysis emlpoys the fields of applied mechanics. The result of the analysis are used to verify a structure fitness for use , often precluding physical tests.

Before modelling the elements the structural engineer should know the loads, forces, moments, deflections and the SFD, BMD, diagrams of the beams and how the structure behave when certain loads act on it. The strucutre should resist all the loads and should be sevicible unless we cannot design the model. The method we us efoe analysing the members and how it behave when loads act on it. The result of analysis helps us to know all the deformation and verifys the structure strength foe its use.

In Revite we use Robot structural analysis to design all the load and find the stregth of the structre and we can redesign the structure.

The design effects the modelling in many ways when we are modelling a structure we should take care that there should not be any overlaps which effects the design we have to do the modelling of the project again. Suppose if need to replace any column size in the strucure in the s per design we need to change in the modelling so the design effects the modelling.

AIM: To export the complete analytical model prepared in the previous weel to the robot structural analysis and check what loads are to be placd and analyze the structural model.

a) A Boudary condition is placed on structure where either the exernal foces or the displacement are known at the stat of analysis. In this way , boudary conditions are where the tructural interacts with the environment either through the application of an external forces or though the some restraint that is imposing a displacement. For a structural analysis problem to be solvable , every loction on the boundary of our structural must have a known boundary condition, either a known forces or a known displacement . The known foces or displacement may have some magnitude or it may be zero. For example, we may know that there are loctions on our structure that have no external foces. This would be a zero foce boundary condition . A displacement boundary condition that is zero is equivalent to the structure being held in place at that loction . The list of parameter requierd are

• Degree of freedom
• Type of support
• Retraints.

b)According to the design standars the following load can be applied to the floor based on strucutre decide.

• Dead load
• live load
• wind load
• earthquake load

c) The load combinations for a my building that i considered are:

AIM: To include the load combinations to the analytical model.

TOOLS USED:

Energy analysis is calculating the amount of enrgy. Energy analysis is the traditional method of assessing the way energy is used in an operation invovling the physical or chemical processing of material and the transfer and conversion of enegy.

Energy analysis is the virtual or computerizzed simulation of a building or complex that focuses on enegy consumptiom, utility bills and life cycle costs of various energy related items such as air conditioning, light and hot water. It is also used to evaluate the payback of green energy solutions like solar panels and photovoltaics, wind turbines and high efficicency appliances. To understan energy modeling, its important to undestand building simulation:

The main objective of energy analysis is to obtain insight into their techological performace for optimal decision making at the design, operations, and contro; levl.

With the help of energy analysi in and out volume of air through the openings and room. With this we can find the defects in our project and rectify the plan in which we dont haveany problem from environment point of view

Performing enegy 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 possiblr .

These are the following steps to be considered to energy aanlyse the building

1. Set the loction of the model

2. Set a weather station for the analysis.

3. Verify enegy settings.

4. Create and analyze the enegy model.

5. Review the analysis on the insight dashboard.

To create a sustainable building which do not cause any harm to humans and living being we need to consider the energy analysis in modeling of Revit.

The factor of sustainablity improve the quality of design beacause sustainablity seeks to reduce the negative impacts on the environment, and the health and confornt of building occupants, there by improving the building performace. The basic objectivity of sustainablity are to reduce consumption of non renevable resouces , minimum waste, create healthy production environment .
