Smart Meters | The next generation devices
Smart meters are next generations devices that help you measure the consumption of electricity and gas. It is different from AMR – traditional Automatic Metering reading in a way that it enable two way communication between the meter and the central system. These smart meters are gaining popularity in the west. They are used for monitoring the energy and gas consumption as well as for billing purposes.
Europe has introduced smart meters that are based on Open smart grid protocol (OSGP) which has the ability to reduce load, disconnect and reconnect remotely. The research conducted in the UK on the usage of smart meters showed that smart meters were being confused with energy meters. They are being used by 1 in 3 homes in the UK. It has been estimated that £300 million could be saved annually if the smart meters are actively used by the people.1 Although it is also important that people actively pay attention to their lifestyle that demand heavy energy consumption.
Smart meters are being used across the world. The aim of using smart meters is to initiate the creation of Energy-Efficient Economy. A study was conducted which showed that homeowners consumption of electricity was reduced by 3-5%.2

Dream Home turning into a nightmare
I took quite some time to write this article. I am really troubled with the idea of people wanting to design their own homes without the help of a Architects or Engineers. It has been really tough telling people that every project is different and needs to be designed accordingly. Every site has different characteristics and hence the design differs.
People are more focused on saving a few thousands that they would have to pay to the experts for getting all the drawings right and in perfect order. They want to do it themselves. For some reason, they believe that they could do a better job than the experts themselves.
I am a professional and I truly appreciate people wanting to participate in the design of their homes, but the participation is limited to suggestions and discussions. The participation of people involves telling the architect about what they imagine their dream house to be. It should be borne in mind that people might have an idea of what they want their dream house to look like but they will never be able to create it. Try me! Describe what you want your house to look like and leave it to me and I will come up with something that will fill your heart with joy.
This is only because I have studied for 7 long years which has helped me develop my design skills. I create what my clients dream and feel. When you describe your ideas to an Architect, he knows exactly what you are looking at and what you want. He is a technical person and a designer and knows how he could turn your dream into a reality.
7 step design procedure for RCC Circular Water Tank
In our previous article, we discussed some important theory and formulas required in the design procedure of Circular Water Tank.
We will now move on with the stepwise design procedure for Water tank design.
Determine the design constants such as σcbc, σct, m, σst
σcbc = permissible compressive stress in concrete
σct = permissible tensile stress in concrete
m = modular ratio
σst = permissible compressive stress in steel
- Dimensions of the tank
- Volume of the tank
- Area of the tank (by assuming its depth)
RCC Circular Water Tanks
Circular water tanks have the properties of the cylinder. Cylinder stress is exerted on the circular water tank. It is distributed with rotational symmetry. The stress distribution remains unchanged if the object is rotated about a fixed axis.
There are three different patterns of cylinder stress namely;
- Hoop stress or circumferential stress – it is in tangential direction
- Axial stress – parallel to the axis of the cylinder
- Radial stress – It is perpendicular to the symmetry axis but is coplanar
Some important theory for Circular Water Tanks
The base of the circular water tank has a flexible joint. The tank rests on the ground. The wall of the tank is designed for hoop tension.
Formula for Hoop tension (Ht)
The formula for calculating hoop tension is,
Ht = PD/2 ———————————— equation 1
P = water pressure on wall
D = diameter of tank in metres
The formula for pressure is given by,
P = d x h —————————————equation 2
d = density of water = 10kN/m3
h = depth of water in metres
Types of construction methods
When you purchase a home, more thought is put into the location and layout of the property than the methods of construction that were used to build it. That is something that becomes incredibly important when you decide that you want to build your own home from scratch. You quickly learn how different structural methods and materials used in the construction can affect the bottom line. With a definite budget in place, you really need to pay attention to all of these details, which usually means that such things as amenities and house features take second place to the actual build.
In our earlier articles, we have discussed an entire guide for RCC construction. The guide includes the detailed procedures for carrying out various different calculations for designing different parts of the building. Foundation design is the most important and first step in the design of RCC structures.
One of the most commonly used methods of construction is one that basically dates back centuries, and that is masonry. Brick and stone are durable materials that can withstand the elements better than most. Building a brick home on a stone slab means that you will have a solid home with a strong foundation, but it is also a little more labor intensive than most of the modern methods that are available today. That additional labour can drive build costs up, but money can also be saved by using re-purposed bricks, which can also add a very unique look to the home.
