Abstract
The rate of exploitation of the energy resources has been expanding over time and resulted in reduction of fossil fuel reserves. Efficiency of all resources is crucial both in environmental and economic sense. Using energy inefficiently creates waste in all the world’s economies. It has environmental impacts with regional, local and global implications.The key object is to adopt energy management in every field in order to reduce the wastage of energy sources and cost effectiveness without affecting productivity and growth.
The presentation will include the following topics:
- Fundamentals of energy modeling
- Overview of the eQUEST energy modeling program
- Recommendations for integrating energy modeling into the design process
- Brief description of baseline energy modeling using ASHRAE Appendix G
- Recommended strategies for reducing energy use
- How to review energy modeling results
-Common problems and how to avoid them
Engineers Angela Vreeland and Gustav Brändström demonstrate common traps and tricks in dealing with trend data, along with detailed calculations that can be applied to a variety of energy saving measures.
The document describes ReCon, a tool to help PepsiCo optimize water and energy usage. It aims to minimize environmental impact through standardized metrics, benchmarking, best practices sharing, and technical solutions. Key aspects include profiling energy use, diagnosing opportunities, setting priorities via a scorecard, training regional experts, and recognizing high-performing sites. The tool focuses on reducing usage in motors, compressed air, steam systems, and recovering waste heat.
This document summarizes an energy modeling analysis that compared the energy performance of seven common gas-fired heating systems for warehouses. The analysis found that direct-fired, high temperature rise blow-thru space heaters used 35-38% less natural gas and 92-93% less fan electricity than the ASHRAE 90.1 baseline system. Using any other type of heater increased energy use by 24-59% compared to the blow-thru heaters. Blow-thru heaters were determined to use the least amount of total energy to heat and ventilate large warehouses based on their design advantages of higher burner efficiency, more efficient controls, and higher discharge air temperatures.
This is a compilation of the overall process in conducting energy audit based on my personal experiences, training that I attended in Malaysia, India and Japan and information sharing between fellow EE practitioners.Not to forget references from books and internet.
I believe this would benefit to those who wants to understand what is energy audit all about for beginners to become energy auditor and to facilities owners to assess the need to conduct energy audit and energy audit proposals submitted by consultants

Comparative Analysis of HVAC System Based on Life Cycle Cost AnalysisIJERA Editor
A heating, ventilating, and air conditioning (HVAC) system is designed to satisfy the environmental requirements of comfort or a process, in a specific building or portion of a building and in a particular geographic locale. Efficient design of heating, ventilating and air-conditioning (HVAC) systems is a primary concern in building projects. The objectives of the HVAC system design are to provide a thermal comfort, good indoor quality and energy conservation. For the typical commercial building projects, it is not difficult to acquire the reference settings for efficient operation. However, for some special projects, due to the specific design and control of the HVAC system, conventional settings may not be necessarily energy-efficient in daily operation. The HVAC system design and equipment selection for a commercial building (376 TR) is included as a case study in this paper. The outcomes of this paper are efficient design of HVAC system with minimum energy consumption and equipment selection based on operating and life cycle cost analysis.

Energy Analysis Plays an Important Role in Purchase DecisionsAvijit Choudhury
This document discusses factors to consider for electricity purchase decisions in Indonesia. It outlines electricity generation and pricing in Indonesia, noting heavy reliance on fossil fuels like coal and oil. Grid electricity prices are regulated and subsidized. Expanding generation from renewable sources like hydro, geothermal, and solar is a national goal. The document also compares costs of electricity from the grid versus gas-fired or coal-fired captive power plants for a factory, noting factors like fuel costs and efficiency. Waste heat recovery and use of gas-fired heat pumps can further reduce factory energy costs versus grid or conventional options.
The document discusses the importance of measurement, reporting and verification (MRV) protocols for energy service company (ESCO) projects in India. It describes a case study of an ESCO project to replace air conditioning units in a hospital where the projected energy savings turned out to be inaccurate due to flaws in the audit methodology. Specifically, the auditor extrapolated power consumption readings across the full run cycle of the AC units without considering that load varies over the cycle. Proper MRV protocols are needed to accurately establish baselines and verify savings to ensure the financial viability of ESCO projects.
This document summarizes a presentation given on the energy aspects of the auto industry. It notes that energy costs for the auto industry are expected to rise significantly in the coming years due to increasing fuel prices and sustainability concerns. While energy currently accounts for 10-15% of production costs, this is projected to rise to 19-26% within five years. The presentation emphasizes the importance of improving energy efficiency across the entire fragmented auto supply chain in order to control costs and comply with environmental regulations on greenhouse gas emissions. It provides examples of incentives for emission reductions and highlights Renault-Nissan's zero-carbon automotive plant as a case study for sustainable operations.

Key aspects of EnMS for forges are examined, such as measuring efficiency of furnaces, hammers and other equipment. The document emphasizes the importance of measurement and suggests ISO 50001 certification can help companies formally establish an effective EnMS.
1. The fertilizer industry in India is energy intensive, with energy costs accounting for 65-87% of production costs.
2. Specific energy consumption (SEC) in the fertilizer industry has decreased over time through adoption of new technologies, retrofitting, and energy management practices.
3. SEC achieved by major fertilizer plants in India after the first PAT cycle ranged from 2.68 to 3.23 GCal/MT of urea, on par with global benchmarks.
1) The document discusses the need to consider additional factors when establishing baselines and measuring performance for power plants under the ISO 50001 energy management standard.
2) These factors include things like fuel availability, scheduling, ambient conditions, planned/forced outages that can impact a plant's loading and efficiency.
3) The document uses a case study of a gas-fired power plant to show how unaccounted factors led to its reported performance deteriorating against its baseline, though the plant operator argued external factors lowered its loading.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
