SIMPLE STEPS TO SAVE ELECTRICITY BILL


We can save electricity simply


Saving electricity at home has become increasingly important in recent years, as excess use can contribute to global warming and leads to massive electricity bills. However, with a few simple steps, you can begin conserving electricity to save money on your monthly bill.
1.
·         1.1. Use more natural lighting. Do you tend to keep the curtains and blinds closed and flip on the overhead lights? Letting your house flood with natural light instead can lead to big electricity savings.[1] Unless you need strong, focused light to complete a particular task, try leaving the lights off during the day and embracing the sun's rays in the rooms you're using.
·         Try to set up your family's daytime work and play space in the brightest room in your house. That way everyone can read, work on art projects, use computers, and so on without relying on artificial lighting.
·         Use light-coloured curtains and blinds as window coverings. Find coverings that provide privacy but still allow diffused light to flood your rooms.

1.2. Designate a few rooms as night hangout rooms for your family. Instead of spreading out all over the house, have your family spend evening hours in just one or two rooms. That way you won't have to light the whole house to enjoy the evening, plus you'll have the added bonus of spending quality time with each member of the family.

1.3. Rethink your outdoor lighting system. Leaving a porch light or path lights burning all night long can waste a lot of electricity. Determine whether having lights on overnight is really necessary before flipping the switch in the evenings.

  •  If you have lights around your house for security purposes, consider getting automatic security lights with motion detectors instead of using lights that stay on constantly.
  •  Decorative lights that complement your garden or pathway can be replaced with solar-powered lights that charge during the day and cast a soft, pleasant glow at night.
  • If you use lights to decorate during the holidays, flip them off before going to bed, rather than leaving them on all night long.



1.5. Use energy-efficient lightbulbs. Replace all of your incandescent bulbs with compact fluorescent bulbs (CFLs) or LED bulbs. Incandescent bulbs release most of their energy through heat, rather than light. Newer bulb styles are much more energy efficient, and they save a lot of electricity and money over time.
  • ·     CFLs use only about 1/4 the energy of incandescent bulbs. They come in many shapes and styles. Be sure to dispose of these bulbs properly, since they contain small amounts of mercury.
  • ·       LED bulbs are slightly more expensive than CFLs, but they last longer and don't contain mercury. LED bulbs are slightly more efficient than CFLs. If you like the ability to customize your environment, LED bulbs come in multicolour and dimmable variants. Some even give you the ability to choose a colour using your cell phone




2.
2.1. Unplug everything. Did you know that appliances and electronics continue sapping electricity as long as they're plugged in, even when their switches are turned off? Making a habit of unplugging these items when they aren't in use saves a lot of energy over time.
·         Power down your computer and unplug it when you aren't using it. Computers are one of the main culprits when it comes to using a lot of energy in a household, so unplugging them when you're finished checking your email for the night is worth the hassle.
·         Unplug your TVs, radios and sound systems. Leaving these plugged in day in and day out is a waste of electricity and money.
·         Don't forget smaller appliances like coffee makers, toasters, hair dryers and phone chargers. These use small amounts of energy, but it really adds up over time.




2.2. Reduce your reliance on appliances. What appliances do you really need to use on a daily basis? Think about your routine and determine where you might be able to save some energy. In some cases, it might mean spending extra time on certain chores, but the reward is saving energy, money, and having the satisfaction that comes with being more self-sufficient. For example:
  • ·         Dry your laundry on a clothesline outside instead of using the dryer. This saves a lot of energy, and many find the old-fashioned task of hanging clothes on the line to be among the more relaxing of chores.
  • ·         Fill your dishwasher to the brim instead of doing a partially-empty load.You could also wash dishes by hand using a water conservation method rather than relying on the dishwasher to do the job.
  • ·         Sweep instead of vacuuming. If you have carpets you'll still have to vacuum once in a while, but you can sweep up large crumbs and clots of dirt with a broom in between sessions. Pulling out the vacuum every day uses up a lot of energy.
  • ·         Do all of your baking on the same day of the week. Heating the oven requires a lot of electricity (unless your oven is powered by gas), so it makes sense to heat it once and bake more than one thing, rather than spacing out your baking over the course of the week.
  • ·         Reduce your reliance on small appliances, too. Let your hair air dry more often than you blow dry it, throw out that plug-in air freshener, and chop food by hand instead of using a food processor.








2.3. Replace your appliances with energy-efficient models. Manufacturers didn't used to pay much attention to how much energy their products used, but times have changed when it comes to the design of large appliances. Many are made to be more energy efficient, and some include settings that allow you to choose how much energy to use in a given cycle. Next time you need to replace a large appliance, do some research to find a model that doesn't use too much electricity. If purchasing appliances made and distributed in the United States, look for an "Energy Star" certification. This certification means the appliance was tested by the United States Department of Energy and it outperforms federal requirements for energy efficiency.
3.

3.1. Use less hot water. Heating water requires a lot of electricity; the more hot water you use, the more your water heater has to produce to keep up. Using less hot water on a daily basis is an important way to conserve energy. Start these new hot water-saving habits:

Wash your clothes with cold water. Unless you're doing a load of clothes that is caked in dirt, it's not necessary to use hot water to wash them; in fact, hot water wears your clothes out much faster.

Take showers instead of baths. Filling a bathtub requires gallons and gallons of hot water; taking a shower uses much less.
Take cooler showers. Do you really need to take a steaming hot shower every day? Try reducing the temperature just a bit every time until you get used to a lukewarm temperature. Save the hot showers for a special treat.

Insulate the water heater. Water heaters that aren't insulated waste energy that gets released from the heater instead of being used to heat the water. Make sure the one you have is insulated, or buy a new model that is designed to conserve energy.

Insulate the pipes in unheated and uninsulated areas of your home, such as the basement by fitting them with pipe sleeves. This is important in climates where winter temperatures can go below freezing because uninsulated pipes can freeze and burst, leading to costly repairs. Even if you don't have freezing winters, be sure to insulate at least the first 3 feet of water pipes (both the cold inflow and hot outflow) from your water heater to reduce heat loss. According to the United States Department of Energy, insulating your pipes with pipe sleeves can save up to $8-12 annually.




3.2. Insulate your house. It's important to make sure your house isn't releasing too much air-conditioned air during the summer or heated air during the winter. If you have cracks in the frames of your windows, under your doors, in your houses basement or foundation, in the attic, or anywhere else in your home, you may be leaking electricity and money.
  •    Have a contractor inspect your home to determine whether additional             insulation may be needed.
  •  Use caulk and door seals to seal the areas around your window and door frames. You can also buy plastic sheeting to cover your windows during the winter.

3.3. Use the air conditioner sparingly. It's tempting to keep the house nice and cool during the summer, but this comfort comes at great expense. Leave the air conditioner off for most of the day, and use it to cool down rooms only when the heat becomes uncomfortable. Use alternative strategies to cool yourself down whenever possible.


  • ·         Take a cool shower during the heat of the afternoon.
  • ·         Open the windows and let the breeze come in.
  • ·         Drink plenty of water and eat ice cubes to keep cool.
  • ·         Spend time outside near a lake, river or pool.


3.4. Keep your house at a lower temperature in the winter. You can save a lot of money by turning the thermostat a few degrees lower during the winter instead of heating your house until it's toasty. Set it just low enough so that you're still comfortable while wearing thick layers of clothing. Wear wool socks and sweaters to keep warm instead of relying on your home's heating system.

If you have all the above requirements we hope you will be a good and successful Civil Engineer. Best of luck.

DUTIES OF CIVIL ENGINEER IN BUILDING CONSTRUCTION SITE:

The major categories where a civil engineer can work on the site are described below:

1. EXECUTION:

Execution intends to convert the design into reality, the planning department will give you detailed drawings for the work you need to convey out. After studying the drawings properly, you will need to discuss with the planning department and project manager for the required assets.
2. QUALITY ENGINEER – QA/QC: QA/QC engineer is responsible for controlling the guaranteed quality to the client. The various quality parameters are chosen during the contract and reported in the project quality plan. All the time of execution, different proforma should be filled by the site engineer, for example, pour cards, checking of reinforcement etc.

3. SAFETY OFFICER:

To be a safety officer you will need extra degree in fire and safety. You will be responsible for the safety of workers, thus you give safety instructions, safety training, pep talk etc to labors time to time. You have the power to stop the work at any stage if safety measures are not followed, for example, welding without the arrangement of the fire extinguisher.

4. PLANNING ENGINEER:

Planning engineer deals with the assets at site. He acts as a medium between the site and higher administration of the company. All assets of materials and labors to be approved by planning engineer for making and following work schedule.

5. BILLING ENGINEER:

Billing engineer prepares the bills for subcontractor and clients.
Except for these posts, there are many different posts where a civil engineer can work suitably depending upon site such as Batching Plant Incharge, Formwork Incharge, Steel Yard Incharge etc.

 

DIFFERENCE BETWEEN CIVIL SITE ENGINEER AND SITE SUPERVISOR:

SITE SUPERVISOR: 

1. Oversee operations on a day-to-day basis.
2. Study the drawings and execute the work by managing the labour, material, and machinery as per daily planning.
2. Ensure that work is done safely, on time and within budget and to the right quality standards.
3. The responsibility of supervising the whole site.
4. Before work starts, a site manager gets things ready by taking on staff, and preparing the site, carefully planning the work to be done and installing temporary offices for site staff.
5. Monitor progress, oversee the delivery of materials and carry out safety checks and sort out any problems which could hold up work as they arise.
6. Supervising the labours at every stage of the construction.
7. Monitoring the work and providing the current status of work to concerned Site Engineer.
8. Keep in close contact with members of their site team at all times, and liaise with architects, engineers, surveyors, and planners.

SITE ENGINEER:

The role of construction site engineer depends on the type of work involved and experience of site engineer in a construction project. The duties and responsibilities of a construction site engineer are as follows, many of these will be delegated to other engineers on the site according to their experience and ability:
1. Setting out the works in accordance with the drawings and specification.

WHY AAC BLOCK???






What is AAC Blocks ?

Autoclaved Aerated Concrete is a Lightweight, Load-bearing, High-insulating, Durable building product, which is produced in a wide range of sizes and strengths. AAC Blocks is lightweight and compare to the red bricks AAC blocks are three times lighter.
Origins
The Autoclaved Aerated Concrete (AAC) material was developed in 1924 in Sweden. It has become one of the most used building materials in Europe and is rapidly growing in many other countries around the world.
AAC is produced from the common materials lime, sand, cement and water, and a small amount of rising agent. After mixing and moulding, it is then autoclaved under heat and pressure to create its unique properties. AAC has excellent thermal insulation and acoustic absorption properties. AAC is fire and pest resistant, and is economically and environmentally superior to the more traditional structural building materials such as concrete, wood, brick and stone.
At the point when AAC is blended and cast in structures, a few compound responses occur that give AAC its light weight (20% of the heaviness of cement) and warm properties. Aluminium powder responds with calcium hydroxide and water to frame hydrogen. The hydrogen gas froths and copies the volume of the crude blend making gas rises to 3mm (⅛ inch) in distance across. Toward the end of the frothing procedure, the hydrogen escapes into the air and is supplanted via air.
AAC Blocks is a unique and excellent type of building material due to its super heat, fire and sound resistance, AAC blocks are lightweight and offers ultimate workability, flexibility and durability. Its main ingredients include sand, water, quicklime, cement and gypsum. The chemical reaction due to the aluminium paste provides AAC its distinct porous structure, lightness, and insulation properties, completely different compared to other lightweight concrete materials.
When the forms are removed from the material, it is solid but still soft. It is then cut into either blocks or panels, and placed in an autoclave chamber for 12 hours. During this steam pressure hardening process, when the temperature reaches 190° Celsius (374° Fahrenheit) and the pressure reaches 8 to 12 bars, quartz sand reacts with calcium hydroxide to form calcium silicate hydrate, which gives AAC its high strength and other unique properties. Because of the relatively low temperature used AAC blocks are not considered fired brick but a lightweight concrete masonry unit. After the autoclaving process, the material is ready for immediate use on the construction site. Depending on its density, up to 80% of the volume of an AAC block is air. AAC's low density also accounts for its low structural compression strength. It can carry loads of up to 8 MPa (1,160 PSI), approximately 50% of the compressive strength of regular concrete.
AAC offers incredible opportunities to increase building quality and at the same time reduce costs at the construction site.
AAC is produced out of a mix of quartz sand and/or pulverized fly ash (PFA), lime, cement, gypsum, water and aluminium and is hardened by steam-curing in autoclaves. As a result of its excellent properties, AAC is used in many building constructions, for example in residential homes, commercial and industrial buildings, schools, hospitals, hotels and many other applications. AAC contains 60% to 85% air by volume.



Advantages Of AAC Block


Fire Resistant

Depending upon the thickness of the Autoclaved Aerated Concrete (AAC) Blocks, they offer fire resistance from 2 hours up to 6 hours. These blocks are highly suitable for the areas where fire safety is of great priority.

Pest Resistant

Autoclaved Aerated Concrete (AAC) Block consist of the inorganic material in its constitution that helps preventing/avoiding termites, damages or losses.

Sound Proof


The porous structure of the AAC blocks results into enhanced sound absorption. The Sound Transmission Class (STC) rating of the AAC blocks up to 45 db. Thus, AAC blocks have been the most ideal material for the construction of walls in auditorium, hotels, hospitals, studios, etc.

Earthquake Resistant

The light weight property of the AAC blocks results into higher steadiness of the AAC blocks in the structure of the buildings. As the impact of the earthquake is directly proportional to the weight of the building, the building constructed using AAC blocks are more reliable and safer.

Faster Construction


As the AAC block is very easy to handle, manipulate and use ordinary tools for cutting the wood such as the drill, band saws, etc. could be easily used to cut and align the AAC. Moreover, the AAC blocks come with larger sizes and fewer joints. This ultimately results in faster construction work as the installation time is significantly reduced due to fewer amounts of blocks and the masonry amount involved is also lowered resulting into reduced time-to-finish.

Long Lasting

AAC blocks are highly superior in terms of the strength. Higher level of strength of these blocks gives higher stability to the structure of the building. AAC is manufactured from non-biodegradable materials, which neither rot nor attract mould, keeping interiors clean and durable.

Cost Saving


AAC block weighs almost around 80% less as compared to the conventional red brick ultimately resulting into great reduction of deadweight. Further,the reduced deadweight results into reduction of the use of cement and steel which helps great in cost savings.

Versatile
AAC Blocks have an attractive appearance and is readily adaptable to any style of architecture. Almost any design can be achieved with AAC.
