Energy Audit of Government Buildings, Industries and commercial establishments

SCHEME ON PROMOTION OF ENERGY ADUIT IN PRIVATE, GOVT. SEMI GOVT. INDUSTRIAL, INSTITUTIONAL, COMMERCIAL BUILDINGS

Govt. of India has enacted the Energy Conservation Act, 2001 with the objective to provide a regulatory frame works for formulation and implementation of Energy Conservation strategies in the country for efficient (BEE) as Designated Agency (DA) to coordinate and regulate the enforcement of the said Act at Central Level.

The Govt. of Haryana has designated the Department of Renewable Energy as the State Designated Agency (SDA) to coordinate, regulate and enforce the provision of the said Act in the State of Haryana. Haryana Govt. has initiated many new schemes for promotion of Energy Conservation in the State.

The Investment Grade Energy audit in Private, Govt. Semi Govt., Industrial, institutional, commercial buildings in one of the activities. The objective of the scheme is to identify areas where excess energy consumption or wastage 0f energy is taking place. It involves measuring the actual energy consumption of various electrical gadgets used in the plants/ buildings, comparing it with an estimate of the minimum energy required to undertake the process and establishing technically and economically feasible means to achieve the same & suggest best ways to optimize the energy consumption leading to energy saving and money saving in electricity bills. In some cases it has been observed that only adoption of best practices result in energy saving with out any or nominal investment. The Energy audit will specify short term, medium term and long term pay back plans depending upon requirement for achieving energy savings. It is advisable to implement the short term pay back plan which results in a recovery of the investment within 2-3 years.

The Owners shall send the duly filled applications form, before and after carrying out the Energy Audit to the Department, through the ADC of the respective district. These applications shall be treated on “first come first basis with the Department. For that the Owner can send the duplicate copy of the application to the Department of Renewable Energy, Haryana directly.

 

GUIDELINES FOR IMPLEMENTATION OF THE ENERGY AUDIT SCHEME IN PRIVATE, GOVT., SEMI GOVT., INDUSTRIAL AND INSTITUTIONAL BUILDINGS. 

 

1.   OBJECTIVE

The objective of the scheme is to identify areas where excess energy consumption or wastage of energy is taking place. It involves measuring the actual energy consumption of various electrical gadgets used in the plants/buildings, comparing it with an estimate of the minimum energy required to undertake the process and establishing technically and economically feasible means to achieve the same & suggest best ways to optimize the energy consumption leading to energy saving and money saving in electricity bills.

 

2.   ELIGIBILY CRITERIA

All Private, Semi Govt., Industrial, Institutional, Commercial buildings owners of Haryana will be eligible for the state subsidy.

 

For Govt. buildings having connected load above 100 KW who undertakes to implement at least 50% recommendations of the energy audit report would be done free of cost by the Renewable Energy department, Haryana.

(ii)         Study of Reactive Power Management and option for power factor improvement.

(iii)        Study of power quality issues like Harmonics, current unbalance, voltage unbalance etc.

(iv)       Exploring the Energy Conservation Options (ENCON) in electrical distribution system.

C)  Lighting System

(i)      Review of present lighting system, lighting inventories etc.

(ii)     Estimation of lighting load at various locations like different floors, outside (campus) light, pump house and other important locations.

(iii)    Detail lux level survey at various locations and comparison with acceptable standards.

(iv)    Study of present lighting control system and recommend for improvement.

(v)     Analysis of lighting performance indices like Lux/m2, lux/ watt, lux/watt/m2 and comparison with norms of high rise buildings.

(vi)    Exploring the Energy Conservation Options (ENCON) in lighting system.

D)  Heating, Ventilation & Air Conditioning System (HVAC System)

(i)      Review of present HVAC system like central AC, window AC, split AC, package AC, Water Coolers and Air Heaters etc.

(ii)     Performance assessment of window AC, split AC and package AC system.

(iii)    Performance Assessment of Chillers, Cooling Towers, Air Handling Units (AHUs)  and cold insulation system of central AC.

(iv)    Analysis of HVAC Performance like estimation of Energy Efficiency Ration (EER i.e. KW/TR), Specific Energy Consumption (SEC) of Chilled Water Pumps, Condenser Water Pumps, AHUs etc. and comparison of the operating data with the design data.

(v)     Exploring the Energy Conservation Options (ENCON) in HVAC system.

E)   Diesel Generator (DG) sets

(i)      Review of DG set operation
