What is NESSI?
The world-wide rising demand for energy and the desire for ecologically more sustainable energy systems increase the urgency towards a quick gloabal and German energy transition. Through renewable energy technologies, the building sector promises, hereby, particularly high savings potential in final energy and greenhouse gas emissions. To reduce the complexity of deciding on an efficient, resilient, affordable and low-emission energy system, we introduce NESSI, the Nano Energy System Simulator of the Information Systems Institute at Leibniz Universität Hannover.
NESSI is a free online web tool for developing baseline and comparative scenarios to create an environmentally, economically, and socially sustainable energy system. Its complexity-reducing approach supports the first steps towards sustainable buildings and neighborhoods including electric mobility for users with and without expert knowledge.
NESSI enables you to quantify the environmental, economic, and social impacts of your individual energy system and, thus, allows you to identify a sustainable energy system for your site. Based on this, you can formulate energy policies and ultimately support the local, German, and global energy transition towards a greener future for all.
To get you started, we created a short manual to guide you step by step through the simulation:
