2: BACKGROUND

The main objective of this walk-through audit is to identify, how energy is

being used in NSIC administration block and help identify practical and cost

effective energy saving measures that will reduce energy use and lowers

operating cost.

2.1 AUDIT SCOPE AND LIMITATION:

This audit report will:

 Evaluate NSIC Administration block’s overall energy performance.

 Highlight number of improvement opportunities.

 Provide an estimation of payback period.

In this walkthrough audit, the following major building-related activities were

investigated:

 Lighting consumption

 Ventilation

2.2 METHODOLOGY

The following activities were performed during and after the Walkthrough

Audit in NSIC:

● Analysis of existing Baseline Energy Consumption(BEC)

● Site inspection and Data collection

● A written report detailing findings, recommendations, approximate costing

and savings with payback times.

2.3 SITE INFORMATION:

The NSIC Administrative block comprises of:

Ground floor First floor

Classroom I Training hall I

Computer lab Computer hardware lab

Seminar hall VLSI lab

Cisco metering hall Embedded systems lab

Electronics maintenance lab Training Hall II

3: ENERGY CONSUMPTION

The major energy consumptions at this facility are:

 Ventilation and Air Conditioning (VAC)

 Personal computer

 Lighting

3.1 SPECIFIC ENERGY CONSUMPTION:

4: DETAILED BUILDING PLAN:

Refer attachment pdf

5: ENERGY EFFICIENCY IN UTILITY AND PROCESS SYSTEMS:

5.1 LIGHTING AND LIGHTING CONTROL

 Class Rooms- Change Lights to LED

5.2 VENTILATION AND AIR CONDITIONING SYSTEMS:

 Class Rooms- Change Fans to Energy Efficient Fans

INVESTMENT  Replacing tube lights with LED bulbs and lights.

 Replacing Fans with Energy Efficient Fans

NOTES:

 If the functioning ACs are to be changed, it can be replaced with BEE

certified 5 star rated ACs.

 Installation of Occupancy sensors helps in the reduction of lighting

hours.
