Speakers for lagislation to have energy-efficient houses
RE Speakers at a seminar on Energy Efficiency in Buildings have emphasised the need of legislation for the construction of energy efficient houses.
The Lahore Electric Supply Company organised the event in connection of World Environment Day at a local hotel here on Saturday. Lesco Board of Directors Chairman Ahmad Rafay Alam and Lesco Chief Executive Officer Saleem Akhtar were amongst the main speakers.
All the housing authorities including Lahore Development Authority must introduce building codes for construction of energy efficient buildings to save the future of the country, they stressed.
Ahmad Alam said that in the coming decades, our planet would be a very different place. By 2050, there would be an additional 3 billion people on Earth and 70 percent of the worlds population would be living in cities, he added.
While many things about the future are remain unclear, one thing is certain that demand for new buildings will increase with more population in urban areas. And unless we change the incredibly inefficient nature of todays buildings, it means an unprecedented increase in energy use, he explained. If we could not adopt efficient technology, save energy, construct environment friendly and efficient energy buildings, it would be a ticking time bomb, he argued. Alam said buildings were one of the largest end user of the energy and that the carbon emission could be reduced by simply improving the energy efficiency in buildings and appliances, he added.
Lesco CEO Saleem Akhtar told the participants that the domestic consumers of Lesco (81.3 percent) consumed 41 percent electricity.
So the domestic end is our most focused areas where we always stress for energy conservation.
Principally energy conservation at the consumer end was better than the investment on a new project. In this way, the money could be saved at both customer and seller ends, he added.
In the Lesco limits, according to him, tubewells constituted 1.6 percent of total customers and consumed 8.2 percent electricity. He informed that commercial consumers were 14.9 percent and consumed 8.6 percent electricity. Saleem further informed that 2.1 percent industry consumers utilised 38.6 percent electricity.
Lesco total consumers are 3.5 million and it require 3,400MW daily to meet the demand of the consumers.
Akhtar, while emphasising the need of hydel and solar power projects, requested that all the educational institutions must develop their own solar system to meet the electricity requirements. We cannot afford electricity generation from oil-based power plants as oil consumption in power sector has increased from 18 per cent to the current 41 per cent.
He said the hydel generation decreased from 38 percent on 2007 to 35 percent by the end of 2010.
The gas consumption in power sector has decreased from 41 percent to 21 per cent on said period, he added.
