Energy Audits for Industries and Commercial Buildings

Pakistan is an emerging economy with a growing number of different industries across the country. The increasing industries provide job opportunities, stability to the economy and raise in the Gross Domestic Product. On the other side, these industries demand an uninterrupted power supply to meet production targets.
According to the Pakistan Energy Year Book (2018), Industries consume 37.46% of the total energy consumption of Pakistan which is the highest among the other sectors. To reduce energy demand, one of the effective methodologies is to conduct energy audit of the industry. The Energy Audit is the process of evaluating the losses in the industry or building due to inefficient equipment and machinery, unjustified load management, and inadequate energy consumption practices. The Energy Audits are conducted under the guidelines of ISO 50002 Standards.
Objectives of Energy Audit
The main objectives of the conduction of energy audits include:
To reduce energy consumption, reduce emissions and equip the entity with state of the art efficient devices. The overall implementation of Energy Management System Implementation under the light of ISO 50001 standards.
Development of a self-sustainable system of continuous improvement of the energy performance
Development of key performance indicators to access the annual energy consumption performance of the port.
Introducing green procurement policy for each every organization working within the premises of the port
Induction of renewable energy resources where ever applicable
Deputing workforce and energy managers for measurement, monitoring and implementation of energy management rules
Utilization of different communication means such as posters, emails, banners and seminars etc. for providing awareness to the working entities for implementation of energy management within the port.
Potential Industries and Commercial Buildings for Energy Audits
Industries
• Textile Sector
• Cement Industry
• Food processing Industry
• Sugar Industry
• Fertilizer Industry
Commercial Buildings
• Hospitals
• Universities
• Offices
• Banks
• Shopping Malls
Process of Energy Audits
The process of Energy audit includes Walk-through audits and detailed audit. The walk-through energy audit helps in identifying the energy wastage, inefficient equipment operating and losses in the overall system. The detailed audit quantitatively evaluates the energy losses. The detailed energy audit includes HVAC energy audits, Electrical, Compression systems, etc.
Expected Outputs after Energy Audits
The expected outputs after conducting the energy audits include savings of million rupees on an annual basis if the recommendations in the energy audit reports are followed properly.
