In the late summer of 2019, we started the search for solutions that can create sustainable lives in buildings under the theme “CHANGING LIVES: CHANGING BUILDINGS”. We received no less than 56 applications from 22 different countries. After a competitive selection process and a corona break, we are now happy to finally present this year’s SUSTAINABLE BUILDING innovators!

This years’ innovators cover a broad field, all of them solutions that contribute with important solutions to how we can live more sustainably in buildings. From platforms that facilitate communities, product and energy sharing over specific products such as flexible ventilation and flooring systems to solutions that will help us change our behavior and introduce a new housing concept.

Meet them here:

ALDStone, Susana Nuria Guerrero Lopez (UK)

ALDStone, a multi-award-winning SME that provides unique building material systems enabling tile reuse. ALDStone products are sustainably selected, designed, produced, delivered and installed, ethically used thanks to its integrated circular systems for flexible attachment, easy removal and the reuse of different tiles at other locations. ALDStone offers a range of products enabling reusability and circularity of tiles of almost any material including stone, ceramic, marble, parquet, carpet, vinyl among other materials, allowing the tile sector to become fully modular.

Boblberg in collaboration with the Danish Red Cross, Andreas Wagner (DK)

Boblberg is a digital community platform that facilitates local communities. The primary purpose is to start dialogues with others that become real-life communities, for example by looking for somebody to run with or the need for fellowship with others in the form of friendships, food clubs, knitting, going to a cafe or the like.

Climate Recovery, Jarl Bengtson (SE)

Climate Recovery is a sustainable ventilation product, with a 2-in-1 solution where ducts and fittings are made of recycled glass that acts as both ventilation and insulation. Climate Recovery becomes part of the energy and systems concept – where the solution offers lower energy consumption for fans, less CO2, lower LCA, faster installation, lower duct costs and lower sound attenuation costs.

Deedster, Anders Åkerlund (SE)

Deedster in an app nudging the users to stepwise lower their CO2-footprint in housing and other areas. By quizzing and advancing in a knowledge structure the user increases their awareness of how to work with carbon lowering activities. Through carbon stamped micro tasks ’deeds’ the user gets challenged to do real tasks with a carbon impact, that is driving the footprint in a decreasing direction.

Enyday, Christopher Tolstrup (DK)

Enyday is a digital platform for energy communities in buildings or districts with collective self-consumption of solar. A “behind-the-meter” energy community could be a large apartment buildings or cluster housing with collective power buy, solar PV, battery storage and EV chargers. When a building has such installation, new needs and opportunities arise. Enyday provides a solution with smart invoicing to ‘self-manage’ their collective electricity usage with significant savings while providing a community application engaging and nudging neighbours to consume energy in a sustainable and responsible way.

Ihopa, Alexander Engl (SE)

Ihopa is a platform that makes group consumption and sharing easy and secure with an easy to follow process, insurance, sharing agreement and all the sharing tools needed to manage shared products, as booking calendar, maintenance, expenses, chat, etc. The ihopa technology can be used by neighbourhoods and friends but also by sellers to directly sell or rent their products to groups.

The webshop gives wholesalers, construction markets and manufacturers with building materials in surplus the opportunity to anonymously sell the goods to completely new customer groups, which include both private individuals, companies and public purchasers. Both sellers, buyers and society win. The seller, who anonymously and at a reduced price can sell the item to completely new buyers. The buyer, who can buy surplus goods at cheap prices, and society, because the goods will be used instead of being scrapped.

TIKKU, Marco Casagrande (FI)

The Tikku house is designed to replace a city’s parking spots with living space. Tikku (‘stick’) is a three-story tiny CLT apartment building, – with a floor for working, another for sleeping, and a greenhouse on the top and it can be built in one night. By using cross-laminated timber, which is five times lighter than concrete, it’s possible to install the tiny house without a foundation.


The world looked a little different when our steering committee made the final selection of this year’s innovators on March 13th. The country was just shut down and we had to postpone our Accelerator Forum. For two of the 10 originally selected innovators, this has unfortunately meant that they have had to withdraw from the Sustainable Build program. The innovators are:

Hearthome (DK)

Hearthome, a platform that creates the foundation for tailor-made neighborhoods and homes suitable for future residents by facilitating the sharing of data on future residents’ housing wishes to property developers.

Kndrd (US)

Kndrd is a property management solution for operators of CoLiving concepts globally – they manage everything from bookings, reservation management, payment processing, invoicing, leasing signature, invoicing, accounting, community management, SEO, etc.

We wish them the best in their future work.


The innovators must now prepare for the SUSTAINABLE BUILD Accelerator Forum on 17th of September, where they will present their innovation to SUSTAINABLE BUILD’s partners and selected experts, including The Landowners’ Investment Foundation, Henning Larsen Architects, NCC, PensionDanmark, Central Region Denmark and Tarkett. Here they will receive advice and support to scale the innovations so that they can be implemented in the industry and contribute to increased growth in sustainable construction and not least a more sustainable life in our buildings.
