Green construction technologies on display at three-day exhibition

Gaining momentum amongst architects and builders is the concept of green building, say participants of the Archibuild at Himachal Bhawan, who have arrived here from across the country. Some of the 'green products' displayed at the three-day exhibition, include green bricks, energy saving devices and fiber cement boards.

A way of dry construction, that takes only one-fourth of building time, using fibre cement boards, is being promoted by a Delhi-based company that provides green solutions. As a substitute to natural wood, it is made from 40 per cent recycled content including fly ash and leaves no by-product on manufacturing. "The advantages of the board is that it is fire and moisture resistant and provides acoustic insulation, and can be used for roofing, flooring or walls depending on the thickness," says Vikas Verma, Marketing Officer.

Also on display are Energy Efficient Bricks, machine made through a de-airing pug mill that processes clay, and removes air from it, using German technology. A company based in Dera Bassi is marketing the bricks that have a smooth finish with an exposed brick look and do not require any synthetic finish.

A Delhi-based company has showcased an Energy Saving Management system that can be installed in hotel rooms and control room temperature by adjusting the AC setting. "In hotels, the air conditioning is never switched off. With the technology, one can adjust the room temperature depending on if one is inside the room or away. A motion detector is installed at the roof and lights, fans and air condition can be controlled at the flick of a switch," says Zishan Ul Haque, Deputy General Manager for the Northern Region. He says that almost 40 per cent energy can be conserved this way, without manual intervention each time.

The concept of green building incorporates and integrates a variety of strategies during the design, construction and operation of building projects that are environment sustainable and eco-friendly.
