Objective<\/h5>\n\n\n\n

To estimate the energy performance index (EPI) of the college building.<\/p>\n\n\n\n

Outcome<\/h5>\n\n\n\n

Students will gain understanding on Environmental performance mapping and Bureau of Energy Efficiency (BEE) guidelines for different typology of buildings and be mindful of it while designing the buildings.<\/p>\n\n\n\n

Requirements<\/h5>\n\n\n\n

Measuring tape (long), Plan of the institute, monthly electricity bill.<\/p>\n\n\n\n

Prerequisites<\/h5>\n\n\n\n

A conceptual knowledge of electrical energy consumption and Energy Performance Index (EPI).\u00a0<\/p>\n\n\n\n

Procedure<\/h5>\n\n\n\n

Step 1: <\/em><\/strong>Identify the climatic zone of the city in which the institutional building is located. <\/p>\n\n\n\n

Step 2:<\/em><\/strong> Obtain the monthly electricity bills  of the college building for the past one year.<\/p>\n\n\n\n

Step 3: <\/em><\/strong>Determine each month\u2019s electricity consumption of the past year from the bill.<\/p>\n\n\n\n

Step 4:<\/em><\/strong> Add these values to get energy consumption of the past year (kWh\/yr).<\/p>\n\n\n\n

Step 5: <\/em><\/strong>Measure the area (in m2<\/sup>) of the building by measuring length and breadth from the outside of the building.<\/p>\n\n\n\n

Step 6:<\/em><\/strong> Estimate the built-up area (in m2<\/sup>) for the entire building by multiplying a single floor area by the number of floors.<\/p>\n\n\n\n

Step 7:<\/em><\/strong> Estimate the EPI (in kWh\/m2<\/sup>\/yr) by dividing energy consumption per year (in kWh\/yr) with the building\u2019s built-up area (in m2<\/sup>). <\/p>\n\n\n\n

Step 8:<\/em><\/strong> Compare the EPI with the benchmark provided by the Bureau of Energy Efficiency (BEE) for institutes.<\/p>\n\n\n\n

Step 9:<\/em><\/strong> If<\/p>\n\n\n\n

    \n
  1. EPIbuilding<\/sub> > EPIbenchmark<\/sub><\/sub> : Building\u2019s energy performance is unsatisfactory<\/li>\n\n\n\n
  2. EPIbuilding<\/sub> < EPIbenchmark<\/sub><\/sub> : Building\u2019s energy performance is good<\/li>\n<\/ol>\n\n\n\n
    Sample Calculations<\/h5>\n\n\n\n

    Step 1:<\/em><\/strong> <\/p>\n\n\n\n

      \n
    1. City : Pune<\/li>\n\n\n\n
    2. Climatic Zone5<\/sup> : Warm & Humid<\/li>\n<\/ol>\n\n\n\n

      Step 2:<\/em><\/strong> Energy Consumption per year (kWh\/yr) = 1,790,000 kWh\/yr<\/p>\n\n\n\n

      Step 3:<\/em><\/strong> Built-up Area of the Building (m2<\/sup>) = 10,000 m2<\/sup><\/p>\n\n\n\n

      Step 4:<\/em><\/strong> Energy Performance Index (kWh\/m2<\/sup>-yr) = $$\\frac{\\:\\text{Energy Consumption per year (kWh\/yr)}}{\\:\\text{Built-up Area of the Building (m2)}}$$<\/p>\n\n\n\n

      = $$\\frac{\\:\\text{1,790,000}}{\\:\\text{10,000}}$$<\/p>\n\n\n\n

      = <\/em><\/strong>179 kWh\/m2<\/sup>-yr\u00a0<\/p>\n\n\n\n

      Step 5:<\/em><\/strong> EPI Benchmark for Institutes (For Warm & Humid Climate Zone)6<\/sup> = 150 kWh\/m2<\/sup>-yr.<\/p>\n\n\n\n

      Step 6:<\/em><\/strong> Since EPIbuilding<\/sub> > EPIbenchmark<\/sub>, the building performance is unsatisfactory.<\/p>\n\n\n\n
