Advancing Energy Efficiency - 2023

Advancing Energy Efficiency - 2023

The project has two tasks:

Task 1: To create scientific evidence for the use of alternative roofing assemblies to support Eco-Niwas Samhita (ENS) is to facilitate the future enhancement of ENS to include the U value performance of the indigenous roofing technology and non-homogeneous industrial roofing technologies. This will specifically help Beneficiary Led Construction (BLC) under PMAY as well as affordable housing schemes to adopt varied technologies that can provide higher opportunities to achieve thermal comfort. It will aid in meeting the larger goal of ENS implementation with a wider range of roofing technologies helping achieve code compliance at an affordable cost. 

Task 2: To derive energy performance test methods for the Personal Environment Control System. Personal Environmental Control System (PECS) with the functions of heating, cooling, ventilation, lighting, and acoustic has the advantage of controlling the localized environment at the occupant’s workstation by their preference instead of conditioning an entire room. This will improve personal comfort, health, and energy efficiency of the entire Heating, Ventilation, and Air-Conditioning (HVAC) system substantially. A large of work exists to understand the comfort performance of the PECS, this will help to develop the common energy performance methods of the PECS. The energy performance methods will help to evaluate PECS performance along with comfort performance and will aid in the adoption of it at code and market.


Task 1

  • Activity 1: Thermal performance of Roofing assemblies to support Eco-Niwas Samhita (ENS). Identification of ten roofing technologies that are non-homogeneous.
  • Activity 2: Development of a testing algorithm for roofing technologies, identification of testing protocols and conducting the test

Task 2 

  • Activity 1: Develop methods to evaluate the Energy Performance of Personal Environment Comfort Systems
  • Activity 2:  A summary of power requirements of different PECS types under different indoor environmental conditions, which will meet the objective of the tasks.

Output and Outcomes

Outcome 1: Database of U value of the non-homogeneous roofing technologies. 

  • List of technologies to be tested for the U Values
  • Stakeholder engagement report for the verification of the selection of the technologies
  • Awareness generated among stakeholders on thermal properties of the roofing technologies for ENS implementation and compliance

Outcome 2: Develop methods to evaluate the Energy Performance of Personal Environment Comfort Systems

  • A report of the literature review and comments from the experts on the same
  • Awareness generated among targeted stakeholders on energy efficiency and thermal comfort aspects of PECS
