Explain or Expand your thoughts in a long paragraph up to five hundred words for each ANSWER from Question 1 to 10

1. What is a "GreenBuilding"?

Answer:

Green Building are characterized by:

• efficient management of energy and waterresources
• management of material resources and waste
• restoration and protection of environmentalquality
• enhancement and protection of health and indoor environmentalquality

2. In the Section 6 of Philippine Green Building Code what is Green BuildingConcept.

Answer:

Green building is the practice of adopting measures that promote resource management efficiency and site sustainability while minimizing the negative impact of buildings on human health and the environment. This practice complements the

conventional building design concerns of economy, durability, serviceabilityand comfort.

3. What is Energy Audit and why do we need to do EnergyAudit?

Answer:

A critical examination of an energy consuming facility. Starting point for implementation and control of an energy efficiency and conservationprogram.

• To set energy efficiency & conservationgoals.
• To identify areas where energy wastes canoccur.
• Relate energy consumption toproduction.
• Improve process / equipmentefficiencies.
• Identify and recommend energy savingopportunities.

4. Why we need energy management for lightingsystems?

Answer:

• It is an essential service to all industries
• Opportunities for lighting retrofits are very common and generally offer an attractive return oninvestment
• Lighting retrofits can also improve the visual environment and workerproductivity

5. Equipment to be used in Boiler Energy Audit and itsusage.

Answer:

Infrared Thermometer - Measures Boiler surface temperature

Combustion Analyzer - Measures Flue Gas Composition and Flue Gas Temperature

Anemometer - Measures Air velocity

Thermo-hygro/Anemometer Measures Air temperature, % Relative Humidity and Air velocity

6. How you are going to implement Motor ManagementPlan?

Answer:

A motor management plan is an essential part of a plant's energy management strategy. Having a motor management plan in place can help companies realize long-term motor system energy savings and will ensure that motor failures are handled in a quick and cost effective manner. Following key elements are suggested for a sound motor management plan;

1. Creation of a motor survey and trackingprogram.
2. Development of guidelines for proactive repair/replacedecisions.
3. Preparation for motor failure by creating a sparesinventory.
4. Development of a purchasingspecification.
5. Development of a repairspecification.
6. Development and implementation of a predictive and preventive maintenance program.

It is important to develop a selection of preferred premium efficiency motors to replace existing motors at failure. Otherwise, it is likely that the motors will be replaced by less efficient alternatives.

7. What is Strategic MotorSelection?

Answer:

Several factors are important when selecting a motor, including motor speed, horsepower, enclosure type, temperature rating, efficiency level, and quality of power supply. When selecting and purchasing a motor, it is also critical to consider the lifecycle costs of that motor rather than just its initial purchase and installation costs. Up to 95% of a motor's costs can be attributed to the energy it consumes over its lifetime, while only around 5% of a motor's costs are typically attributed to its purchase, installation, andmaintenance.

8. How to implement better Preventive Maintenance in yourplant?

Answer:

Preventative maintenance includes training personnel to be attentive to energy consumption and efficiency. While many processes in aggregate crushing plant production are primarily automated, there still are opportunities, requiring minimal training of employees, to increase energy savings. Also, preventative maintenance can also increase a plant's utilization ratio, since it has less downtime over the long term, and improve process stability.

9. Explain impact of Compressed Air Leaks in yourplant.

Answer:

Leaks can be a significant source of wasted energy. A typical plant that has not been well maintained will likely have a leak rate equal to 20 to 50% of total compressed air production capacity. Leak maintenance can reduce this number to less than 10%. Overall, a 20% reduction of annual energy consumption in compressed air systems is projected for fixing leaks.

Estimations of leaks vary with the size of the hole in the pipes or equipment. A compressor operating 2,500 hours per year at 87 psi with a leak diameter of 0.02 inches ( mm) is estimated to lose 250 kWh per year; 0.04 inches (1 mm) to lose 1,100 kWh per year; 0.08 inches (2 mm) to lose 4,500 kWh per year; and 0.16 in. (4 mm) to lose 11,250 kWh per year.

In addition to increased energy consumption, leaks can make air tools less efficient and adversely affect production, shorten the life of equipment, lead to additional maintenance requirements and increase unscheduled downtime. In the worst case, leaks can add unnecessary compressor capacity.

The most common areas for leaks are couplings, hoses, tubes, fittings, pressure regulators, open condensate traps and shut-off valves, pipe joints, disconnects, and thread sealants. A simple way to detect leaks is to apply soapy water to suspect areas. Another simple way is a bleed down test. In a bleed down test the plant air system is brought to full pressure and then shut down. By recording the system pressure while compressed air is not used anywhere in the plant, any pressure losses can be attributed to existing leaks. The best way to detect leaks is to use an ultrasonic acoustic detector, which can recognize the high frequency hissing sounds associated with air leaks. After identification, leaks should be tracked, repaired, and verified. Leak detection and correction programs should be ongoing efforts.

10. How you will implement Energy Management Systems and Programs in yourplant?

Answer:

Improving energy efficiency should be approached from several directions. A strong, corporate-wide energy management program is essential. Crosscutting equipment and technologies such as compressed air and motors, common to most plants and manufacturing industries, including crushing plant, present well-documented opportunities for improvement. Equally important, the production process can be fine-tuned to produce even greater savings.

Although technological changes in equipment conserve energy, changes in staff behavior and attitude can also have a great impact. Energy efficiency training programs can help a company's staff incorporate energy efficiency practices into their day-to-day work routines. Personnel at all levels should be aware of energy use and company objectives for energy efficiency improvement. Often such information is acquired by lower-level managers but neither passed up to higher-level management nor passed down to staff.

Energy efficiency programs with regular feedback on staff behavior, such as reward

systems, have had the best results. Though changes in staff behavior (such as switching off lights or closing windows and doors) often save only small amounts of energy at one time, taken continuously over longer periods they can have a much greater effect than some other more costly technological improvements.

Changing how energy is managed by implementing an organization-wide energy management program is one of the most successful and cost-effective ways to bring about energy efficiencyimprovements.
