4. Energy Audits
Energy audits can be classified as under:
• Walk-through audit: A preliminary inspection of site to observe the
various processes and identify glaring areas of energy waste or inefficiency
• General audit: A detailed inspection of all energy consuming processes
backed up by past operating data. Identification of all energy conservation
measures followed by detailed financial analysis for each measure
• Investment-grade audit: Projected operating savings from the
implementation of energy projects are developed such that they provide a
high level of confidence. Extensive attention is given to understanding not
only the operating characteristics of all energy consuming systems, but
also situations that cause load profile variations on short and long term
basis.

7. Renewable Energy Potential Assessment
(REPA)
Dependence on conventional energy can be greatly reduced with
the use of modern renewable energy systems.
Ambicales has worked extensively & studied about various
renewable energy technologies that can be applied for offsetting
conventional energy demand in buildings, school/college
campus, temples, industries, etc.

8. Renewable Energy Potential Assessment
(REPA)
We look at facility specific energy demands that can be offset
by the following:
• Solar energy systems
• Solar photovoltaic
• Solar thermal
• Biomass energy systems
• Biomass gasification
• Biogas Digester
• Hybrid energy systems

15. Case study
A new 70 bed hospital in Bijapur, Karnataka has a sanctioned
load of 50 kVA.
The following describes in brief the walk through audit
conducted at the hospital.

16. Case study
Power Factor Correction

January 8000 0.78 2880
February 9634 0.80 2890.20
March 10546 0.81 2847.42
April 11235 0.76 4718.70

*Power factor specified by utility is 0.90.
**Penalty of 3 paisa per unit consumed is levied for every reduction of pf by 0.01 by
0.90 lag

17. Case study
Average power factor of 0.80 will be considered for calculations.
Average energy consumption over the period is 10035.4 kWh.
Average power factor penalty over the period is Rs. 2877.44.
The solution is to install Power Factor Correction (PFC). It is
recommended that the PFC unit be of 15 kVAR capacity. The
cost of the unit is approximately Rs. 20000.
Projected savings are Rs. 34529/yr with a simple payback period
(SPP) of 0.57 years or 7 months.

18. Case study
Motor Load Test
A detailed motor load study was undertaken on all continuously
operating motors, with help of clamp on energy meter to
measure instantaneous parameters.
Star mode operation of under loaded motors (which are loaded
below 45 % of the rated capacity) results in improved
operating efficiency.
The following motors at the hospital were under-loaded
