Energy Conservation and Audit — What This Subject Is About
Saving energy is often cheaper than generating it — and on a construction site or in a building, the savings are everywhere: motors, pumps, lighting, boilers, air conditioning. Energy Conservation and Audit is Open Elective-02, Option B (or you can take Renewable Energy Technology, or an Advance Skill Development certification instead). It is a 50-mark internal-only subject, so it does not add to the semester total.
The subject starts with the basics of energy and the Energy Conservation Act 2001, then walks through the places energy is lost — electrical supply systems and motors, lighting and DG systems, boilers, furnaces and cooling towers — then the Energy Conservation Building Code (ECBC), and ends with everyday energy saving tips and what an energy audit actually is: its types, methodology, instruments and reporting format.

The electrical side — supply systems, transformers, tariffs, power factor, motors, pumps, compressed air and HVAC — and where energy is wasted in each.
Unit 3 — Lighting and DG Systems (6 Periods, 20%)
Lighting systems: basic definitions — lux, lumen and efficacy; types of different lamps and their features; energy efficient practices in lighting. DG systems: introduction, energy efficiency opportunities in DG systems, loading estimation. Energy efficiency in thermal utilities. Thermal basics: thermal energy, energy content in fuels, energy units and its conversions in terms of Metric Tonne of Oil Equivalent (MTOE). Energy conservation in boilers and furnaces: introduction and types of boilers, energy performance assessment of boilers, concept of stoichiometric air and excess air for combustion, energy conservation in boilers and furnaces, do's and don'ts for efficient use of boilers and furnaces. Cooling towers: basic concept of cooling towers, tips for energy savings in cooling towers, efficient steam utilisation.
Lighting and diesel generator systems, boilers and furnaces, and cooling towers — and the energy-saving opportunities in each.
Unit 4 — Energy Conservation Building Code (ECBC) (4 Periods, 15%)
ECBC and its salient features; tips for energy savings in buildings: new buildings, existing buildings; waste heat recovery and co-generation: concept, classification and benefits of waste heat recovery, concept and types of co-generation system.
The Energy Conservation Building Code (ECBC) — its salient features and tips for saving energy in new and existing buildings, plus waste heat recovery and co-generation.
Unit 5 — General Energy Saving Tips (5 Periods, 20%)
Energy saving tips in: lighting, room air conditioner, refrigerator, water heater, computer, fan, heater, blower and washing machine, colour television, water pump, cooking, transport; energy audit, types and methodology, energy audit instruments, energy auditing reporting format.
Everyday energy saving — lights, AC, fridge, fans, pumps, cooking and transport — and what an energy audit is, its types, methodology and instruments.
Instead of This Elective — Advance Skill Development
The 6th-semester scheme allows an Advance Skill Development certification course to be taken instead of Open Elective-02. No course name is given for the 6th-semester option in the PDF (unlike the 5th semester, which names Advanced Plumbing, TATA TECH.). No detailed contents for this certification course are given in the PDF.
