Potential savings in lighting energy due to advancement in indian standard time: an enquiry in context of commercial office spaces in India.
Padmini Rajaram, Rajan Rawal Abstract:
The study aims at quantifying the savings in lighting
energy consumption for office buildings in India due
to the permanent advancement of Indian standard
time from +0530 to +0600 GMT. The study initiates
by walk through energy audit to evaluate lighting
load and occupancy details for Ahmedabad and
Kolkata. This data is used to
develop reference
models for simulations and determine lighting energy
consumption. The time advancement is analyzed by
shifting occupancy schedules for office spaces, hence
parametric combinations of occupancy schedules
with different floor plate sizes, aspect ratios, window
wall ratio with lighting controls are analyzed. Results
from these models show 6.29% savings in the
lighting energy consumption.
