CHAPTER-5 DATA ANALYSIS & DISCUSSION

INTRODUCTION

This Chapter presents the results of the data analysis addressing objectives started in Chapter 1. It Is Also Includes the interpretation of the study from the data collected.

5.2 ANALYSIS OF ENERGY EFFICIENCY OF ALTERNATIVE CONSTRUCTION TECHNOLOGY WITH COMPARED TO CONVENTIONAL TECHNIQUES

The EPI of Conventional Techniques is 66.46 Kwh/m2/annum.

● As per the collected data We stimulated the data collection and found that there are many technologies in this have different EPIs came in it and the first one was the modular tunnel form, whose U value was 3.36 W/m2K. Energy save is increased by 12.5 percent over conventional Technology. This simulation has unexpected Outcomes.

● The second technology is the insulating concrete form, whose U value is 0.32 W/m2K, its EPI 28.34 Kwh/m2/annum, which means that the energy save of this technology is 57.36 percent, which according to the Bureau of Energy Efficiency comes in the 5 star rating.

● The third technology is the Plaswall Panel System, whose U value is 2.7 W/m2K, its EPI 49.97 Kwh/m2/annum, which means that the energy save of this technology is 24.81 percent, which according to the Bureau of Energy Efficiency comes in the 2 star rating.

● The fourth technology is the Rapid Panel, whose U value is 0.503 W/m2K, its EPI 34.79 Kwh/m2/annum, which means that the energy save of this technology is 47.65 percent, which according to the Bureau of Energy Efficiency comes in the 4 star rating.

● The fifth technology is the Quick Build 3D Panels, whose U value is 0.61 W/m2K, its EPI 36.87 Kwh/m2/annum, which means that the energy save of this technology is 44.52 percent, which according to the Bureau of Energy Efficiency comes in the 4 star rating.

● The sixth technology is the Waffle-Crete Building System, whose U value is 5 W/m2K, its EPI 95.99 Kwh/m2/annum, which means that the energy is not save & increase of this technology is 44.43 percent. This simulation has unexpected Outcomes.

● The seventh technology is the Walltec Hollow core Concrete Panel, whose U value is 2.5 W/m2K, its EPI 47.95 Kwh/m2/annum, which means that the energy save of this technology is 27.85 percent, which according to the Bureau of Energy Efficiency comes in the 2 star rating.

5.3 UNEXPECTED OUTCOMES

After simulating this we found many unexpected outcomes in this technology such as 12.59 percent energy increase in modular tunnel form and 44.43 percent energy increase in waffle crete building system which shows that these two technologies require more energy than conventional technology.

5.4 LIMITATION OR CONSTRAINTS

In This research We simulate only seven technologies which are given their U-Value to analyze their energy efficiency. So this research is limited only to seven techniques.

5.5 DISCUSSION IN PRACTICAL APPLICATION

A lot can be done in the affordable housing sector in Delhi by using other technologies except modular tunnel form and Waffle crete building system because in rest of the technology, the best technology is insulated concrete form which is having the best energy efficiency, and it comes under 5 year rating Plan of composite climate in Delhi , so use it, it will have a very good impact in the affordable housing sector. And another Rapid Panel and Quick Build 3D panel Should be also applicable in Alternative construction technology in delhi.
