Nanotechnology, the smallest technology is used in concrete materials to improve the quality. Nano particles used in the concrete will have a size ranging from few nanometers to 100 micrometers. If these nano particles are operated with nano tubes and sensible nano silica particles, then very strong and tough cement can be developed with increased properties.

Rainwater Harvesting is a practice followed by India, Pakistan, Afghanistan, and Iran at 3rd century BC to collect and store rainwater from rooftops, land surface, and more. Due to rapid urbanization, the ground water recharge has been decreased drastically. So, this technology is now implemented in almost all parts of the world for the increasing ground water level, wells, pits, and trenches.
Have a loot at the below ppt for in-depth details on how a rainwater harvesting system is done:
A green concrete is a user-friendly concrete, which uses minimum amount of energy in its production and produces less carbon dioxide than standard concrete. Recycled materials are the main ingredients of green concrete. The optimized mix design helps in providing easier handling, consistency, and finishing.
The below ppt brings you the brief details about green concrete:

Building Automation is an advanced system, which is computerized to automate the functions of the building. It is generally known as Building Automation System (BAS). It consists of a distributed control system to provide intelligent use of electronic devices with the help of electronic, mechanical and lighting systems of a building.
Have a look at the below ppt to know more about BAS structure, topology, and its applications:
