What are HVAC systems ? Why are they essential in modeling of buildings

HVAC system is one of the important component in the modeling of a building. The term HVAC stands for Heating, Ventilation and Air conditioning. Now lets get into these terms, Heating means to increase the temperature of the input air which flows into the building. ventilation can be defined as the replacement of the old air present in the room with new fresh air this can also be said as input of fresh air and output of stale and bad air. Air conditioning is a well known term which means that to allow cool air into the building.

THESE ARE ESSENTIAL IN MODELLING BECAUSE:

HVAC systems have become mandatory in these days as the technology is developed and everyone are used to comforts. With proper HVAC systems we can increse the sustainability and condition of the building environment. Italso improves the comfort and increases the workability of the members.

Mainly these HVAC systems are used at malls, offices and large clubs where the population is more. As the population is more more amount of air will be required otherwise it leads to suffocation. These days people have started paying more intrest regarding their health, with the help of automatic HVAC systems we can control the internal temperature very easily.

Proper HVAC systems are worthy investment for any business because it gives energy savings .HVAC systems today are automated ,which means onew is no longer have to manually adjust temperature settings of each machine .Entire HVAC system operates in an automated system ,proper adjustments will be made right when they are needed.This makes one energy consumption more efficient as it get rid of energy wasted on improper settings

If the outside environment temperature is more automatically the colling system will on and moderates the temperature by allowing more cool fresh air. If the inside temperature is cold the system activates the heating system or heaters, which gradually increses the temperature and makes us feel comfortable. So HVAC systems are important and are essential in modeling a building.

3) Use the add-ins tab to load plug-ins for robot structural analysis to your Revit software

AIM:TO LOAD PLUG INS FOR ROBOT STRCUTURAL ANALYSIS FOR REVIT SOFTWARE BY USING ADD-INS TAB

Steps to add ins tab to load plug-ins for robot structural analysis :

• First check whether the robot structural analysis is enabled or disabled.

• If not avaliable we have to download it from auto desk store.
• click on the trolley logo (or) shopping cart logo on the top of revit.

• The autodesk store opens, in the search box type structure analysis followed by the respective version /year of the revit software.

• Then download the tool.
• The robot structural analysis will be reflected in our revit software.

RESULT:

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

Structure is one of the important component in a building. We cannot imagine or achieve a successful building without a proper structure. The structure framework acts as a skeleton framework to the building. All the loads are being taken by the structural part. The architecture part only plays an important role in the appearance of the buliding.

Structure analysis is very important to a building as to know how much load can the building bare and how long the building can with hold the loads. Before the construction of the building we do not have all the componnets installed in the building like walls and other components, so before we construct the building we have to do the analysis on taking appropriate load values to calculate how much load the structure can bare. After the construction of the building if the structure collapses as it cannot hold the load, then we cannot do anything. We can calcutale the total load, deflections, SFD and BMD.

Structure analysis can also be considered as a demo test or sample test to get a detailed strength of the structure. In a building we have many types of loads like point load, uniform load, area load and so on. So in this analysis we can add the type of load we want and assume the load values to test our structure. It is considered better if the structure holds more load than the load capicity calculated in the analysis.

The design affects the model so we have to place the columns at such places where they do not cause much disturbance and at places where it can hold maximum amount of load. So thus we can conclude that it is necessary to do the structure analysis while modeling elements and we can say that the design affects modeling.

5) From the structural model developed in week 6 and 7, export the complete analytical model to robot structural analysis.
a. List your assumptions on what boundary conditions will be realistic for analysis approach
b. Use the design standards to decide what loads must be applied to floorings based on the type of structure decided
c. List the load combinations and include them in analysis model
d. Analyze the building and report the following results
i. Maximum Moment in each floor for all Load Combinations
ii. Maximum Displacement in each floor for all Load combinations
iii. Lateral Displacement in building for all Lateral Load combinations
e. After analysis , do you think you have a better approach or idea in modeling structural members ?

AIM:TO PERFORM ROBOT STRUCTURE ANALYSIS TO THE BUILDING MODEL WHICH WAS CREATED LAST WEEK MODEL

a) Boundary conditions are the conditions which are to be satisfied at all parts of a biundary region where differential conditions have to be solved separetely. For the analysis of the structure we have to have loads, as in oue case we do not have any loads so we have to assume suitable amount of load for the analysis. We have have forces in any direction along X, Y or Z axis. We have to assume that the total moment as 0 and the structure is in equilibrium. We have to place loads at suitable places so as to complete the analysis. The list of parameters required are :
1. Degree of freedom.
2. Supports.
3. Type of load.
4. Opposing loads.

b) We can apply different types of loads based on our requirements like:
Dead load.
Live load.
Earthquake load.
Wind load.

C)LOAD COMBINATIONS:

totL NUMBER OF FLOORS IN MY BUILDING ARE THREE FLOORS INCLUDING GROUND FLOOR I HAD APPLIED TWO LOADS AND MENTIONED IN BELOW PROCESS

PROCEDURE:

1)First we have to open the structural template file which was created previously week

6) 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 ?

Energy analysis is a way where we can calculate the amount of energy used in an operation which involves physical and chemical actions which also plays a role in transfering and exchange of energy. With the help of energy analysis we can analyze the in and out volume of air through the openions and rooms. With this analysis we can find out the defects in our project and rectify the plan in which we do not have any problems from the environment.

In this analysis all the components are taken into consideration like electric equipments and other equipments which releases heat into the environment. The energy analysis is very important in the modeling of project in revit because if the energy released is more it may cause human and environmental damage.

We have to implement different techniques where the energy released could be minimized like using renewable sources of energy like solar panels, biomass, wind energy and so on. We have to recycle most of the products which does not cause more damage to the environment.

We can peform the energy analysis for revit models by using energy analysis for autodesk revit. This add-in ci=onnects the design power of the revit project file to the Autodesk green building studio which acts as a basic constrain for calculation and evaluation
