Study suggests replacing imported construction materials with timber

Timber with its improved mechanical and durability properties is fast gaining the reputation as the structural material of the 21st century. Given the pressure on the climate, environment and our rapidly depleting resources because of the housing sectors' heavy reliance on concrete, steel, and other industrial products, the potential of timber as an alternative to these materials is keenly explored by the industry and researchers worldwide. The motivation to build in timber comes from a compelling combination of low cost, faster construction time, better safety outcomes on-site, reduced or eliminated carbon emissions and excellent strength to weight properties all packaged in the natural warmth and comfort that wood elicits.   

Various technologies and forms of engineered timber products with the potential to revolutionize the way we build our infrastructure are being tested and emerging. This paper discusses the natural advantages of timber as a structural material and explores the recent innovation and development in the field of timber engineering.

The future of timber as a sustainable and viable material for meeting the housing demand for the ever-burgeoning world population is presented. It also discusses the scope and the necessary institutional and infrastructural precursors required to tap the benefits of this natural material in Bhutan.

7th Green Technology Challenge on Design and Fabrication

7th Green Technology Challenge on Design and Fabrication

7th Green Technology Challenge on Design and Fabrication of Low-Cost Standby Power Generation System.

College of Science and Technology (CST) in collaboration with Tarayana Foundation (TF) has successfully implemented the project on low-cost standby
power generation system on 2nd June 2019.

This is the 7th year of collaboration between CST and TF. The past projects include:
1. Low-Cost Solar Dryer (the Year 2013)
2. Low-Cost Water Filter (the Year 2014)
3. Low-Cost Insulation Material (the Year 2015)
4. Low-Cost Solar Fencing (the Year 2016)
5. Low-Cost Solar Thermal Heating (the Year 2017)
6. Low-Cost Drip Irrigation (the Year 2018)

As in the past, the preference is given to prototype fabricated using locally available materials and low cost, so that it is affordable to rural communities.

For low-income people, it is important to find appropriate solutions taking into consideration the local economy of the people and local entrepreneurs, as well as the available skills, tools, materials and other resources to create affordable products for improved living conditions and livelihood. 

The purpose of this partnership is to work together to put forward a competition among the Engineering students in the CST to develop the models best suited to Bhutanese conditions. The selected models are replicated and distributed to rural communities for improving their livelihood and the dependence on fossil fuel.

This year, out of 27 proposals from student groups from various programs, only the best five were selected. In two months’ time, the selected groups had to optimize their design and fabricate it.

Two months of hard work finally ended today with groups presenting their design and demonstrating the working model to the jury members. The jury members included experts and engineers from Bhutan Power Corporation Limited, Druk Green Power Corporation Limited, Tarayana Foundation, and CST. Among the five participating groups best three were selected based on their originality, efficiency, affordability, marketability, and materials used. Certificates and cash prizes of Nu. 30,000/-, Nu. 20,000/-, and Nu. 10,000/- were awarded to winning team, 1st Runner-up team and 2nd Runner-up team.
