Building Energy Management Systems and Baseline #5

BUILDING ENERGY MANAGEMENT SYSTEM : BASELINE DEVELOPMENT

How to read data from the regression results are as follows:

 

R Square shows the quality of the data. The closer the value of 1, indicating the quality of the data, the better. R Square so if you are still below 0.7 then these figures indicate the quality of the data you enter is very bad quality.

If the baseline equation is written as follows: Y = AX1 + BX2 + CX3 + DX4 + E 
the values of A, B, C, D and E can be taken from the table above.

If the baseline is taken from the data of 2014, productivity performance year 2015  can be measured using this table. 

If the estimate> actual, it means you've done saving, if the estimate <actual then you plant performance is decreasing.

Building energy management system using the data analysis features of Excel
After having production data and consumption of energy in your hand, then you must activate the feature "data analysis" on your Excel software.

Click data analysis then this menu will show up

Select Regression, then this menu will show up

If we want to create a baseline consumption of gas and evaluate the performance of reheating furnace of the consumption of natural gas, then input Y range in from this data

Input X range from X1 to X4. Click OK. It will appear in the new results sheet as follows:

Thus, building energy management steps can be grouped as follows:

1. Appoint management representative as the representative of the management company. 
2. Appoint a certified energy manager. An Energy Manager must have a certificate issued by an independent agency. An energy manager must be able to plan, lead organization, in coordination with the Area Incharge, implement energy conservation activities, bringing the team to achieve the set targets management 
3. The management company must build a team and organization to implement energy management, led by the energy manager.
 4. Socialize energy management activities.
 5. Each element management should make a joint commitment.
 6. Provide sufficient training for all components of the company at all levels.
 7. Conduct an audit conducted by a certified auditor.8. Implement the recommendations on the results of the audit activities of the Energy Management System.9. Creating a baseline, set a plan and the target company in the field of Energy

Building Energy Management Systems and Baseline (1)

Building Energy Management Systems is always linked to the Baseline. Baseline is a reference to the performance of a factory. A Plant has better productivity or deteriorating base on baseline. Baseline can be a linear function AX1 + BX2 + C = Y, A and B are constants, X1 and X2 are produktitivas when there are two kinds of products, and C is the total energy required.

Supposing the factory has two types of products. Then Format Baseline like AX1 + BX2 + C = Y, wherein X1 and X2 are the amount of production. A, B and C are constants.

A, B and C are constants obtained from linear regression. The data taken as a reference for establishing baseline is data when the plant is running under normal conditions with the highest productivity. So the baseline is used as a reference for next year.

In Building Energy Management System, baseline is the reference. If saving is negative means that the performance of a plant is decline.

Building Energy Management System as the Energy Saving Solution #3

ENERGY MANAGEMENT SYSTEMS PRACTICES

Building Energy Management System should be made by all levels of the company. Both from the management to the operator. After you perform several steps that have been mentioned in the previous page, now you get into the deeper stages. Namely the application of energy conservation in significant equipment energy use.

Energy Conservation Activities as Energy saving solutions

One kind implementation of Building Energy Management System is energy conservation. Energy conservation at each significant energy use would vary according to the character of each machine. What to do in business is the Energy Conservation :

1. Data collection.
The data is in the form of operating procedures, energy consumption, energy consumption intensity of the volume of production, as well as operating parameters. From these data it can be seen how efficient the machine level and where the energy loss.

2. Analyze Opportunity for Improvement.  

After learning opportunity for improvement then made a priority scale in accordance with company policy. Opportunity for improvement does not have to be a change of equipment or repair equipment. Opportunity for improvement can be improvement of work procedures.

Each activity improvement efforts must be noted whether repair work procedures or equipment repair and replacement of equipment. The recording was made before and after repair. Not only the physical condition but also data of energy consumption, production volume and the intensity of energy consumption on the volume of production.

Energy Audit and Energy Conservation

You can conduct audit for an equipment by your self , but much better if  you call an expert. Supposing you will audit a boiler, you call the expert boiler. Then you can get what percentage of the boiler efficiency and the audit resulted in a recommendation of what should be done so that the boiler efficiency is increased. Supposing a coal powerplant boilers have an efficiency of only 30%, then the results of the audit found some abnormality in the boiler as well as some procedures that do not fit. By doing certain improvements expected efficiency can be increased up to 34%. How much should be done to fix the boiler and how many benefits. All of the data appearing in the recommendation of the audit activities.

It can be concluded that building energy management system as an energy saving solution is very important for a company. Neither company managing the plant, as well as an office building or mall. Keywords of implementation of EnMS is  socialization energy management system, the company's commitment, the audit and implementation of audit recommendation is the key of success in Building energy management system.

10 Quick Tips to Save More Electricity

10 Quick Tips to Save More Electricity

 Being energy-efficient and lowering your electric bill can save a few dollars each month, which adds up to extra money in your pocket. But how can we cut our electric bill without making major sacrifices or investing extra money to see some savings? Check out these 10 simple tips on how to lower your electric bills and save more money each month.

1. During warmer months, use appliances like the clothes dryer, dishwasher and oven in the morning or evening when it is cooler outside. Your AC will not have to work as hard to keep your home cooler than if you used them when outside temperatures are at their highest.
2. Purchase black out curtains to hang in windows that the sun comes in. 
3. Use night lights in kids bedrooms/bathrooms rather than leaving the lights on for them. This will ease their fear of the dark and light their way in the night if they need to get out of bed. 
4. Be sure to always turn off the lights in the room you’re leaving. Even if you think you’re coming right back, it’s best to conserve electricity while you’re not in the room!
5. Invest in a toaster oven to cook small dinners or sides. It’s easy to pop a casserole/dish in the toaster oven to cook instead of using the big oven. There's no need to warm up the whole oven when you only need to cook one thing.
6. Close the vents in rooms you rarely go in! Instantly you can reduce the square feet you have to cool or heat.
7. Cook meals in bulk. It’s very easy to double a recipe to create twice as much food and left overs for the next day. It will prevent you from having to heat up the oven all over again.
8. Baths use a lot more water than showers, which means a lot more electricity to heat the water. Take a shower instead and purchase a low-flow shower head to reduce water/electricity consumption even more.
9. Insulate your pipes. If your pipes are in an unheated garage or exposed beneath your house, insulate them with pipe-insulating foam. By adding insulation to pipes you will prevent them from freezing and the hot water pipes will stay warm. 
10. Use the low-wattage bulbs when you can. There’s no need to “over light” a room—Bright lights are handy for hallways and closets but the lamps in your family room can be a bit dimmer.
