Through the implementation of the code, there is a scope to save around 30% of energy along with monetary savings of Rs.538 crore per annum in Andhra Pradesh alone. Hence, the government is looking to expedite its implementation in all commercial buildings and expand it to the residential sector in the near future.
The ‘Zero Carbon Buildings for All Initiative’ launched at the UN-Climate Action Summit
Currently, less than 1% of the buildings in the world are net-zero in terms of carbon. Considering that the building sector consumes a substantial amount of energy, the world needs to rapidly move towards a decarbonized building sector & tackle climate change. At the recently held UN-Climate Action Summit at New York, USA, leaders from the national and local level launched the ‘Zero Carbon Buildings for All Initiative.’ This proposal aims to unite officials from all sectors to develop & implement policies to to accelerate decarbonization of new buildings by 2030 and existing building by 2050. Previously, zero carbon buildings were considered a target only for wealthy countries. But the current initiative is looking to implement it in all the countries irrespective of their development status.

World’s First Low Carbon Greenhouses to come up in UK.
Agriculture is one of the top five carbon intensive sectors! However, the decarbonization of this sector is progressing at an alarmingly slow rate. Taking a huge stride in this direction, Greencoat Capital (an asset managing company dedicated to the resource efficiency and renewable energy sectors), UK is investing 120 million to construct UK’s largest greenhouses near Norwich and Bury St. Edmunds.
The greenhouses in UK are among the largest ones constructed, each covering more than 13 hectares.Greenhouses are designed to capture and store solar radiation, thereby increasing air temperature and accelerating plant growth. In Europe, solar radiation alone cannot provide sufficient energy to reach optimal growing temperatures throughout the day. To overcome this, greenhouses generally utilize gas-fired boilers to increase the temperature.
The proposed advanced greenhouses will be warmed via heat pumps through residual heat from nearby water recycling centres. Further, electricity for the heat pumps will be provided by a Combined Heat and Power (CHP) plant, with waste heat from the CHP providing further warmth for the greenhouses.
The St. Patrick’s Cathedral, New York goes Green!
Equipped with Manhattan’s largest geothermal plant, the renovated St. Patrick’s cathedral is offering valuable lessons for making historic buildings resilient & effective. Costing 177 million dollars, the cathedral which is perceived as one of the first successful examples of religious architecture in the “new” world, has undergone major renovation efforts. The design innovations include laying of a closed-loop geothermal plant which penetrates 2,200ft into the bedrock to draw water for heating & cooling purposes, installation of high performance glazing, low flow plumbing & installation of LED bulbs. Moreover, extensive efforts have been diverted into enhancing the biodiversity of the site in terms of both flora as well as fauna. Covering around 40% of the garden area, tree canopies offer seasonal blooms, fruit production & ecological restoration which in turn attract a variety of birds & insects.
Challenging traditional religious buildings, St. Patrick’s cathedral serves as an outstanding example in creating a sustainable, cost-friendly place of worship which will inspire the present as well as the future generations.
