Aktivplus eV is a German construction initiative that incorporates sustainability into the fabric of buildings and neighbourhoods. The organisation is open to planners, scientists and other members of the construction industry who are interested in developing sustainable standards.
The Aktivplus eV non-profit association was launched in 2013. Its founding members were Norbert Fisch, Gerd Hauser, Gerhard Hausladen and Manfred Hegger.
In 2014, the Aktivplus standard (originally referred to as the AktivhausPlus standard) was introduced by the founding members at the association’s first official symposium. This was followed by the release of a pilot programme for Aktivplus in 2015. A user manual for the standard was published in 2016.
Over the years, experts from architecture, science, engineering and related disciplines have participated in the development of the Aktivplus standard for buildings and people. As of July 2020, there are 70 members of the Aktivplus eV community.
There are currently 25 buildings that have been planned based on the Aktivplus standard. These structures include single family homes, apartment blocks, a local government building and a day care centre.
 Comparison to Active House
Energy usage in buildings is the basis of the Aktivplus standard, which seeks to integrate beneficial energy consumption and generation for the benefit of building occupants, infrastructure and the overall environment. As a standard, Aktivplus calculates energy and CO2 emissions per square metre and per person.
Active House emphasises three primary principles - comfort, energy, environment - and nine key factors. Energy is a shared principle of Active House and Aktivplus, but Aktivplus also looks at users, networks and building lifecycle (or four primary principles). Instead of nine factors, Aktivplus examines 14 key criteria - eight qualitative and six quantitative.
In both instances, buildings that adhere to the standards do so both in the planning stage and in the operating stage. With Aktivplus, the quantitative criteria must also be achieved after the first and second year of the building’s operation.
Instead of using the Active House radar diagram to map out how these factors work together, Aktivplus objectives for the building are presented in a flower diagram. Reaching beyond the boundaries of the physical property is another component that sets Aktivplus apart from Active House. The idea of establishing an interconnected network within a neighbourhood is particular to the Aktivplus standard, which sets out to create buildings that are connected to their surroundings.
 Key factors
Four primary principles - energy, users, networking, lifecycle - have been designated as the driving factors behind Aktivplus. Within each of those principles there are 13 factors in addition to the basics.
- Final net energy.
- Self sufficiency.
- Building performance.
- Networked buildings.
For Aktivplus eV members, there are tools available to assist with calculations.
