Building Energy Efficiency Analysis

Problem Statement

Building Energy Efficiency. Energy consumption by different heating and cooling load has been done here on some buildings.

The buildings differ with respect to the glazing area, the glazing area distribution, and the orientation, amongst other parameters.

Perform exploratory analysis on the given data-set

  1. Use graphical analysis to describe the pattern.
  2. Try to answer the following questions –
  3. Which consideration while construction should be taken care for reducing the further power consumption.
  4. Which of the given features does not affect much on the cooling load.
  5. Find out some more pattern out of data.
  6. Show minimum 6 graphs which shows some strong pattern.


Support your findings with some real-world logic.



From the Correlation plot, we can see that the Labels Heating load and Cooling load have a value of 0.98. So we can use only one of the value for further analysis. So we will choose the heating load.


The graph shows that building having more height (7) need more heating load than the ones which are of low height (3.5). Buildings with high height value have more variance than the one with low height which has very little variance relatively


This graph shows that the buildings with lower height(3.5) have more Surface Area and Roof Area compared to the buildings with higher height(7)


A heating load has less variance with building with low height( 3.5) no matter the roof area. In case of buildings with height 7, it has the larger variance. As the wall area is increasing it seems the variance is decreasing in higher buildings.


The roof area of smaller buildings is similar in dimension and Roof Area of taller Buildings have more variance. More the Roof Area lesser the heating load.


Relative compactness has a good positive correlation with correlation with Overall Height. So it increases with the height of a building and hence increases Heating Load.


You can say there is an increase in heating load as glazing area increases. Though the distribution doesn’t affect heating load much.


The best features to consider to reduce Heating or Cooling load are

  1. Buildings with Shorter overall height.
  2. Increase Roof Area and Surface Area.
  3. Decrease Wall Area of the building.
  4. Decrease Relative Compactness.
  5. Decrease Glazing Area.

Glazing Area Distribution and Orientation have no effect on the Heating or Cooling Load.

So the building with less Heating and cooling load is made as a short building, make sure it’s as small as possible in height. Increase the Roof size..i.e. It should be shorter in height and longer in length and width.

Try to decrease the glazing Area. So make it such that less sunlight comes inside…

This is all about Building Energy Efficiency.
