Abstract
Buildings account for over 30% of the world’s energy consumption and are therefore a key contributor to a country’s energy as well as carbon budget. Understanding how buildings use energy is critical to understanding how any new policy may impact a building’s energy use. Data enables decision-making, and good quality data arms consumers with tools to compare their energy performance relative to their peers. This allows them to differentiate their buildings in the real estate market on the basis of their energy footprint. Good quality data are also essential for policy makers to prioritize their strategies as well as track implementation and impact. Several countries have effective efficiency programs in the buildings sector that are developed on the basis of good quality data. However, lack of consistent and comprehensive data on commercial building energy end-use and energy using equipment stock in India’s case continues to impede effective tracking of building energy consumption as well as performance. In this paper we review the experience of countries across the world with different approaches and systems to collect building energy data, some of whom maintain it on a regular basis. Utilizing others’ experience, we explore potential use cases and approaches for establishing a comprehensive building energy data framework for India.

Notes
Since the service sector in India comprises mainly business services, real estate, construction, institutions, hotels, restaurants, and other services, it is a significant indicator of the growth of the buildings sector.
including detailed data on ownership and activity (building occupancy type/ activity type/ green mark labelling), building data (gross floor area, carpark area, number of rooms, major retrofitting), building services information (lifts/ ACMV/ lighting/ hot water systems/ building electricity and other fuels consumption.
Three stakeholder consultations were held as part of a Roundtable on Commercial Building Energy Data Framework, in New Delhi, India (December 2015, February, and August 2016).
