High-speed, future-proof district heating Hengelo
Check out the project video below:
The city of Hengelo is investing firmly in smart and sustainable city solutions with several projects under way to achieve their 50% reduction target in CO2 emissions by 2020. Since 2010, Thermaflex works closely with district heating engineers from Warmtenet Hengelo (Heating network Hengelo) to formulate solutions that ensure rapid installation of networks that minimize installation costs, and disturbance to the existing environment and its residents.
The aim of this particular project was to advance the speed of the housing connections, often the most tricky and time-consuming part of the installation of district heating networks. This meant opening an entire street, trenching, laying and making the house connections to the network before closing the street in the shortest time possible.

The project was officially realized in full in June 2016. The next steps regarding performance evaluation and monitoring are already in place, for which Thermaflex continues its close cooperation with Warmtenet Hengelo to ensure network efficiency, as well as supporting potential expansion in the future.
Keen to take up that challenge, Thermaflex set a new world record with the connection of an entire street in just a single day! This was achieved through the development of the revolutionary FlexaNet concept: a completely pre-fabricated network section with the house connections readily attached to the main line, 100% secure and factory-tested. Up until today, not a single maintenance issue has occurred in the network.
Excellent network engineering and tailor-made preparation and testing of FlexaNet in the Thermaflex factory in Waalwijk rooted this success. The specially trained and certified system partners of SOP proved the possibility to meet the target with the necessary site preparations. This way, installation time could be cut by 80%, while limiting disturbance for the neighborhood to a bare minimum, securing access for residents again by night.
Stats:
• 80% reduction of total planned installation time
• 1 day to connect 10 house hold to the grid
• 50% CO2 reeducation targeted by 2020
• 4400 households enjoy future-proof, sustainable heating
• 9,500 tons of C02 saved per year (which is the equivalent absorbed by 475,000 trees)
On one hand, through adopting high-speed, pre-fabricated, and therefore controlled district network solutions like FlexaNet in high-density living spaces, communities can enjoy future-proof comfort at minimal cost when it comes to daily life and/or trading. On the other hand, by minimizing the need for on-site connections, labor, time and overhead costs can be drastically cut, ensuring optimal control over planning and construction schedules. With a holistic approach, respecting the needs and wishes of all stakeholders involved, cities can secure resilient communities with a smart and sustainable energy supply.

Get up at your feet and join for a summer excursion in Amsterdam-Noord! Although we see more and more solar panels in our streets, as a resident you see very little of the energy transition in the neighbourhood. in Amsterdam, there is already a neighbourhood where the future has started: Buiksloterham in Amsterdam North. Buildings in this area are natural gas-free and almost all of them obtain their energy in a different way.
Be aware that the main language is Dutch!
To make this visible, little glimpses have been placed in the public space. The art objects give virtual glimpses into the devices and installations behind walls and in basements. On the pavement, a 3D painting shows where the district heating network runs, and a viewing tube shows you how full the neighbourhood battery is underground. If you walk past it often enough, you will start to see connections: the weather was really nice today, so the battery is completely full!
During this Waag Open, we'll take a walk alongside different glimpses. All facets of the energy tranisty are covered: we show how deep the boreholes of the thermal storage are and where exactly the heat from the heat network comes from. There is also a focus on solar panels, batteries and heat pumps - of all shapes and sizes! Take a walk with us on Thursday 1 August and you're bound to learn something new about the energy transition!

Het is allang geen modewoord meer. Mycelium. Nu deze schimmeldraden steeds meer hun weg vinden in onze bouwwereld, willen wij weten: wat zijn de voor- en nadelen ervan? En wat kun je er, naast isoleren, nog meer mee?
Biobased appartementencomplex
Tijdens het gratis toegankelijke, informele Innovation Dinner van 19 mei willen we van gedachten wisselen over de potentie van 100% biobased bouwen. Rob Buren en Reyer Witteveen presenteren de inzichten die zij opdeden in de 1ste fase van de BouwLab-studie naar een biobased appartementencomplex. Hans Borra en Roland van Driel vertellen u alles wat u wilt weten over het toepassen van mycelium. Tot slot zal architectenbureau RU+PA u inspireren met de mogelijkheden die zij zien voor dit biobased bouwmateriaal. Dit doen ze onder meer aan de hand van hun mock-up voor een hoogbouwelement, dat door Vianen is geproduceerd conform de uitgangspunten van de studie. Uw kritische feedback nemen we graag mee naar de 2de fase: een gevalideerd en realiseerbaar ontwerp.
Sandwichtpaneel
De bouwsector is al een tijd op zoek naar nieuwe ontwikkelingen en toepassingen om de bouw te verduurzamen. Met de komst van mycelium als bouwmateriaal kan er een goede stap gezet worden naar het verminderen van de CO2-uitstoot. Ondanks verschillende testen en projecten zijn ‘bakstenen’ van mycelium nog niet sterk genoeg voor het échte constructieve werk. In combinatie met hout kunnen we wel tussenwanden en prefab gevelelementen maken. De nieuwe ontwikkelingen van de CarbonBrix en het sandwichpaneel van Hans Borra en Roland van Driel stemmen absoluut hoopvol.
Het Innovation Dinner wordt georganiseerd in samenwerking met EDIH Digital Hub Noordwest. We streven naar een evenwichtige verdeling van deelnemers vanuit overheden, maatschappelijke organisaties en het bedrijfsleven. Om deze reden kan het zijn dat je registratie voor dit Innovation Dinner niet automatisch leidt tot deelname. Wij behouden wij ons het recht voor om een selectie te maken van deelnemers, gebaseerd op criteria die het beste aansluiten bij de doelstellingen van ons Innovation Dinner.
The heat transition is in full swing. Municipalities want their residents off the gas and want them to switch to renewable sources of heat. Unfortunately, heat grids have often led to frustrated residents. Which in turn has led to delayed or cancelled plans for the municipality.
Dave van Loon and Marieke van Doorninck (Kennisland) have looked into the problems surrounding heat grids and came up with a plan. In this Demoday work-session we dived into the problems surrounding heat grids and their plan to solve them. The session was moderated by our own Leonie van Beuken.
Involving residents in the planning of a heat grid is difficult. It takes a lot of time and effort and the municipality is often in a hurry. This is why they choose for a compromise in which they already make the plan, but try to involve citizens at the end part. However, this leads to residents not having anything to say in the plans. They can block the plans, but they can’t really make changes. This leads to a lot of dissatisfaction.
This top-down approach doesn't seem to be ideal for involving residents in the heat transition. That's why Kennisland is working on developing a plan for early collaboration with residents in the heat transition of neighbourhoods, with a focus on connecting with the community's concerns.
They have seen that this kind of approach can be successful by looking at the K-buurt in Amsterdam-Zuid-Oost. In the initial stages, the first plan for the K-buurt didn't gain much traction. However, when they shifted towards a more collaborative approach, people felt empowered to engage, leading to a more meaningful participation process. Instead of traditional town hall meetings, discussions took place in community spaces like the local barber shop. This shift towards genuine participation and co-creation has resulted in a much-improved end product, one that residents truly support and believe in.
The plan that Kennisland came up with consists of a few key points that are necessary for success:
• Engage with residents early on in the process.
• Also consider other issues in the neighbourhood. There might be more pressing concerns for the residents themselves.
• Ensure accessibility for everyone to participate.
• Truly collaborate on developing a list of requirements.
• Harness creativity.
• Work in a less compartmentalized manner.
They aim to form a neighbourhood alliance and organize a community council. Together a plan can be made for the neighbourhood that all residents can get behind.
This plan might take a bit longer at the start, but that investment in time will pay itself back in the end.
After Dave and Marieke explained their plan we did a SWOT analysis with the group. We looked at the Strengths, Weaknesses, Opportunities, and Threats of the plan.
The main strength that was pointed out was the ability to make a plan together with the residents. The residents experience the neighbourhood differently than a government official, which makes the final plan more beneficial to everyone.
The weaknesses the group saw in the plan were mainly that this could potentially slow down the process. Should we maybe do less participation instead of more and use force to get this heat transition going?
There were a lot of opportunities identified for this plan. The quality of the plan (and the neighbourhood) can greatly increase. By slowing down at the start we can actually accelerate and improve the neighbourhood on many levels. This plan also offers a great learning experience.
Finally, we went into the threats. One of the big threats that was pointed out was the lack of trust. If residents don’t trust the municipality and the process then it will never be possible to let this plan succeed. The explanation to residents also needs to be understandable. The explanation around a heat grid can get technical very quickly, and residents often don’t have the background to understand everything. The last threat that was pointed out was that if you get a lot of input from the residents for the plan, you also have to do something with that, and still be realistic. You have to work hard to manage expectations.
We completed the session by asking the participants if they knew any partners and places to collaborate with for this plan, or if they had any other ideas to make this plan successful.
We would now like to ask the same questions to you! Do you know someone who would like to partner up with Kennisland, do you know a place where this plan can be tested, or do you have any other ideas? Let us know by contacting me at noor@amsterdamsmartcity.com.
