This is a complex question that requires you to do some reading, as it confuses even electricians. The applicable reference is: NEC 220.40 Feeder and Service Calculations.
Typically if you are asking this question you should call an electrician to help you. However if you read the applicable NEC article you will be able to calculate your own service.
This can be done by using a clampmeter, this is a instrument that clamps over the main incoming cable ( hot wire ) where it enters the distribution board. You set the meter to read amps and this gives you the total amps being used at that time.
I always ask the customer to find their electrical useage for the last twelve months. Use the highest month in KWHr, divide that by days in month, then hours in day, then supply voltage such as 240-volts. This will show the highest average ampere demand for which your service conductors are supplying. Don't forget to convert to watts at the end.
Surprisingly, most homes average about 10 amps continuous or less. Minimum service rating is 100 amps.
If you are paying $.1 per KWHr and the bill is $150 over 30 days, then you used 1500 KWHr, or 8.68 amps per hour continuously on average.
You could simply install socket power readers on all the outlets that have electrical appliances attached to them, and that would give you an indication of your power usage. If you wanted to know amps, then that's something else all together.
In residential installations, this is usually not a necessary factor to calculate. The utilities companies usually only offer 100 amp, 200 amp or 400 amp service. The typical new home in today's market will use the standard 200 amp service.
If you have concerns like having a garage that you will do work in using electrical equipment, then you would want an electrician to calculate the additional load. 200 amp service is quite adequate for most purposes unless you have the aforementioned scenario. My son has a welding shop and business and operates the entire shop with 200amp residential service including a 3 phase generator.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

To calculate a building footprint, you typically measure the length and width of the building's base or foundation. You then multiply these measurements to get the area of the building in square feet or square meters. This calculation provides an estimate of the ground area covered by the building.
To calculate the number of concrete blocks needed for a building, you first need to determine the area of one block and then divide the total building area by the block area. Concrete block sizes vary, so you will need to know the dimensions of the block you plan to use. Once you have that information, divide the total building area (25x30) by the block area to find the number of blocks needed.
A standard ground rod is 5/8 x 10'. The amount of rods needed is governed by the electrical code. The largest type of grounding system is a Ufer ground. This is where the bare grounding conductor is embedded in the footings of the building and the weight of the building presses the ground wire to the earths surface. These types of grounds are used mostly in construction and are requested by electrical engineers.
A building service is a system or infrastructure within a building that provides essential facilities such as water, electricity, heating, ventilation, and air conditioning. These services are crucial for the functioning and comfort of the occupants within the building.
In electrical terminology it is the same as a distribution panel. It gets called a utility panel because it is the first device that is connected to the utility company's service connection when it enters a building. The utility panel is not owned by the utility company, it belongs to the home owner and it his responsibility to ensure that it is installed correctly and safely. In most cases an electrical inspector has to give his recommendation that it be connected.

how many appliance circuits needed for 15 unit building
Understanding civil engineering drawings is a basic skill needed for electrical engineers as these drawings give them a perspective on how the building is being built and how electrical appliances will be installed or provided.
Quantity of steel in building is calculated in many method. many engineer use to quantify the quantity of steel in a building by referring to detailed planned so they can compute the approximate weight of steel needed.
There is no standard diagram for a small domestic building power circuit. The power needs of the building will determine the size of the breaker box and voltage needed. Local electrical codes will also change the way that the building is wired.
The purpose of a service drop wire is to connect a building to the electrical grid, allowing electricity to be delivered to the building. It functions by carrying the electrical current from the utility pole to the building's electrical meter, providing power for lights, appliances, and other electrical devices inside the building.
Lightning protection is needed in high rise buildings to prevent damage to the structure, electrical systems, and occupants from lightning strikes. Tall buildings are more likely to be hit by lightning due to their height, and without proper protection, the electrical surge can cause fires, equipment damage, and pose a safety hazard to individuals inside the building. Implementing lightning protection measures such as rods, conductors, and grounding systems helps to safely redirect the electrical current from a lightning strike to the ground, minimizing the risk of damage and ensuring the safety of the building and its occupants.
Mass and volume are needed to calculate the density of a graduated cylinder.
A grounding rod is a metal rod buried in the ground near a building. It works by providing a path for excess electrical energy to safely dissipate into the ground, preventing it from damaging the building's electrical system. When there is a surge of electricity, the grounding rod redirects the excess energy away from the building, reducing the risk of electrical fires and ensuring the safety of the electrical system.

Services available for maintaining and repairing the electrical systems in a building's ground infrastructure include electrical inspections, troubleshooting, repairs, upgrades, and installations. These services are typically provided by licensed electricians or electrical contractors who are trained to ensure the safety and functionality of the electrical systems in a building.
