Online- and monitoring tools

co2online was the first company to launch online consulting tools in the field of climate protection and energy efficiency in early 2000. Meanwhile, it has developed a consulting package of more than a dozen online tools on a variety of topics such as modernization, promotion and energy saving. The centerpiece is the energy savings account, which continuously accompanies consumers in their activities.


The "EnergiesparChecks" from co2online provide consumers with individual and neutral advice on energy saving and energy efficiency in the areas of heating, electricity, production and water. The online consulting tools assess the consumption and building data of homeowners and tenants, provide experts on site and then give recommendations on energy and cost savings. More than 12 million consultations have been completed since 2003.

Since 2007, the "Energiesparkonto" has made electricity and heat consumption visible and compared energy consumption and energy costs with those of similar households. It enables long-term energy monitoring for consumers, communities and businesses. The dedicated energy saving account community participates in product tests and surveys. Furthermore the tool is being continuously developed further for project partners such as the European Union or the Federal Environment Ministry.
