Online Tool Tracks Apartment Energy Use
"In 2013, the Lithuanian capital, Vilnius, created an interactive online energy map allowing residents to access and compare energy performance data for 4,799 apartment blocks in the city. The city hopes the detailed and user-friendly information will spur homeowner associations to undertake energy efficiency upgrades that will help the city reduce its CO2 emissions.
To make comparisons easier, buildings have been grouped into 15 classes based on energy efficiency and color coded for display on the map from green (very good) to purple (very poor). Users can select a particular building, and then view a pop-up window showing energy-related information, including the building’s energy efficiency class for each winter for the three last seasons, building type and construction year, and monthly energy efficiency graphs to date. As a bonus feature, the online map enables users to see the financial and energy use benefits from energy-saving solutions, including roof insulation, window and door replacement, and heating and ventilation system modernization."
