After aviator projects successful a metropolis authorities schoolhouse and a Perumbakkam lodging analyzable showed that chill extortion coatings could little indoor temperatures by up to 5°C during highest summer, the Tamil Nadu authorities connected Thursday released a State-level modular operating process (SOP) to standard up the involution crossed homes, schools and nationalist buildings.
Launched connected June 5, marking World Environment Day, the SOP is intended to standardise the implementation of chill extortion coatings, which is simply a passive cooling measurement that reflects star radiation and reduces vigor absorption by gathering surfaces. The papers was released by Environment and Climate Change Minister V.K. Rajeev and Forests Minister R.V. Ranjithkumar.
Developed by the Tamil Nadu Green Climate Company (TNGCC) and the Tamil Nadu Climate Change Mission (TNCCM) successful collaboration with the United Nations Environment Programme (UNEP) and Seeds Technical Services, the SOP lays down procedures for extortion assessment, aboveground preparation, coating application, prime control, safety, and maintenance.
According to the government, a aviator task astatine the Perunthalaivar Kamarajar Government Girls Higher Secondary School successful Ambattur reportedly reduced schoolroom temperatures from astir 31-32°C to 26-28°C. Indoor aerial and ceiling aboveground temperatures fell by astir 4°C to 5°C, helping classrooms stay wrong acceptable thermal comfortableness levels during schoolhouse hours, the SOP says.
The SOP besides cites a aviator involution astatine the resettlement tract successful Perumbakkam, wherever chill extortion coatings were applied implicit astir 1,000 sq. m of extortion country covering 120 lodging units. The task recorded extortion aboveground temperatures that were 6°C to 8°C little than accepted roofs and indoor temperatures that were little by 4°C to 5°C during highest summertime months.
Officials said the Perumbakkam involution besides resulted successful a 20% simplification successful cooling vigor request and astir 30% less thermal discomfort hours.
Reducing AC dependence
The SOP says that roofs are among the largest contributors to indoor vigor summation successful blistery and humid regions and that reflective coatings tin importantly amended thermal comfortableness portion reducing dependence connected air-conditioning and different mechanical cooling systems.
The papers prescribes a 12-stage implementation model covering feasibility assessment, worldly procurement, extortion preparation, spot testing, primer application, coating, prime assurance, and periodic maintenance. It besides recommends the usage of precocious solar-reflective coatings and outlines method specifications for procurement and implementation.
Environment, Climate Change, and Forests Secretary Supriya Sahu said the SOP would service arsenic the implementation model for larger chill extortion programmes successful the State and could enactment arsenic a exemplary for different States looking to amended vigor resilience portion reducing vigor request and emissions.
