Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

Energy Efficient Construction

 


 

Context :

Energy Efficient bricks for govt projects proposed   /  BL – 12 March 2021


Extract :

Ministry is proposing that all government-funded construction projects use bricks certified as energy efficient, Minister of State (Independent Charge) for Power and New & Renewable Energy RK Singh said on Friday.

Under a new scheme being implemented by the Bureau of Energy Efficiency, fired clay brick manufacturers, who lower energy use during their manufacturing process, will be labelled as ‘ Energy Efficient Enterprises (E3) ’.

“It should take around three years for brick manufacturers to implement these energy efficiency reforms, after which we have proposed that any government-funded project such as the Pradhan Mantri Awas Yojana use only E3-certified bricks,” Singh said at the launch event for the scheme.

Singh also said that India will overachieve on the country’s voluntary commitment under the Paris Agreement to raise the share of non-fossil fuel sources in the national electricity generation capacity to 40 per cent.

“Share of non-fossil fuels in our power capacity is already at 38 per cent today. It will reach 60-65 per cent by 2030,” Singh said. “We are the only country who will achieve its pledges under the Paris Agreement.”

Dear Shri Hardeep Singh Puriji,

(  Minister for Housing )


About 10 weeks ago, I wrote to you :


Congratulations, Shri Hardeep Singh Puriji  [  03 Jan 2021 ]

 

In addition to the 6 technologies chosen by your Ministry for trial in 6 cities, I urge you to explore Construction Technology reported underneath, which has following advantages :


Ø  Energy Efficient

Ø  Recycles used Plastics

Ø  Speeds up construction

Ø  Light Weight

Ø  Longer Life

Ø  Easy to Transport

Ø  Can be printed at site

Ø  Lower Cost

3D printed plastic beams are stronger than steel

Lightweight 3D-Printed Lego-Like Beams Are Just as Strong as Concrete  /  Interesting Engineering / 11 Mar


Extract :


Researchers have developed and patented a new 3D-printed beam that assembles in a similar way to lego pieces, and is much less heavy than traditional concrete or metallic beams. 


The team from the Universitat Polytècnica de València (UPV) in Spain, explains that its beams use recycled plastic as the raw material, can be printed and assembled in situ thanks to their 3D-printing nature, and weigh up to 80 percent less than regular reinforcement beams.


After three years in the making, all in all, these new beams appear to be more sustainable, lighter, easier to assemble and transport than concrete or metallic beams, which could change the tides in the construction industry. 


"It is a very intelligent natural system and its reproduction in these beams awards them, with the low structural weight, very high mechanical capabilities," says José Ramón Albiol, [ joalib1@ csa.upv.es ] one of the researchers of the study.

 

The main novelty of the beams lies in its polymeric profile, which enables the pieces to be assembled, linked, and concreted wherever needed. There are no metallic components to the beams, which means they don't corrode with time.


Even though the beams' weight isn't as heavy as concrete beams, they still maintain their structural rigidity, explains Albiol.


The way the researchers managed to minimize the weight so drastically was by using an alveolar structure, a natural system that can be found in human bones, and which was the inspiration for the structure. 


On top of all that, as they're 3D-printable, the beams are more easily customizable nearer the construction site, which also simplifies transportation and lowers costs.


"To be able to customize the beams in situ makes it possible to adapt the characteristics of each of them to the structural needs at each point of construction," mentions Miguel Sánchez, from the Department of Systems and Computer Science (DISCA) of the UPV.


The team patented its creation in October last year, and it'll be interesting to see how the construction world integrates and welcomes these beams.
