A B2B2C energy efficiency calculator that estimates the condition of residential buildings and suggests improvements to achieve a higher Building Energy Rating (BER). My design has attracted the interest of Hungary's largest bank.
Challenge
To educate people and help them to upgrade their houses.
Over 1.5 million houses in Hungary are below class "DD"–the European Union issued that by 2033, the entire residential building stock must achieve an average "DD" energy class. The Hungarian government can provide support for renovation at any time, and the market must be prepared for it.
Eltinga identified a gap in the market and aimed to be prepared for the upcoming renovation wave with a web application that provides more detailed information than its competitors.
Solution
The energy efficiency calculator provides results that serve as a guideline for renovations.
After researching and analyzing interviews with residents and financial companies, I first write the content of the survey part of the calculator (questions and answers) and put them into a proper flow.
The web application has six parts: general survey, partial results, detailed survey, full results, summary, offers.
With the full results, users receive specific renovation tips. "DD" is the default value. The calculator shows how much people could save annually by reaching "DD" status. If their homes are already rated "DD" or higher, the calculator also provides suggestions for a higher class.
Eventually, the product wasn't launched because of business reasons, but I personally believe the calculator was a great idea because home renovation is crucial, and Hungary lags behind other European countries in this area.
Findings show that Hungarians are interested in home renovation, and banks are here to support them, but many people lack sufficient information about improvement opportunities as well as the condition of their own homes. That's why a calculator like this would be educational to all the audiences.
