The 10 technology work packages for offgrid housing

10 interconnected Technology Work Packages (TWPs).

TWP	Technology package	Main technologies	Maturity/TRL	Main development question
1	Ultra-efficient homes	Passive design, insulation, triple glazing, heat recovery ventilation, smart appliances and responsible occupants.	High	How low can annual and peak demand realistically become?
2	Renewable generation	Solar PV, solar façades, residential wind, solar thermal	High	What generation mix survives a Dutch winter?
3	Electricity storage	Central BESS, household batteries where useful, bidirectional EVs	High/Medium	How many hours/days of autonomy are economically optimal?
4	Heating	Heat pumps, low-temperature network, thermal buffers, seasonal storage	High/Medium	Can heat storage reduce the required electrical battery dramatically?
5	Microgrid	Local AC/DC grid, inverters, protection and islanding, black start.	High/Medium	How do 50–250 houses operate safely without the public grid?
6	Water	Rainwater capture, storage, filtration, potable/non-potable treatment	Medium	How much mains-water independence is technically and legally achievable?
7	Wastewater & nutrients	Greywater reuse, local biological treatment, nutrient recovery	Medium	Can water and nutrients circulate within the neighbourhood?
8	Waste & materials	Separation, composting, optional anaerobic digestion, material reuse	High/Medium	Which waste streams can economically become local resources?
9	Mobility	Shared EVs, smart charging, V2H/V2G, e-bikes	High/Medium	Can vehicle batteries become part of community energy storage?
10	Digital brain	EMS, IoT, digital twin, forecasting, AI optimisation	Medium/High	How can all nine systems behave as one autonomous utility?

The critical innovation is TWP 10. It turns the other nine packages from a collection of sustainable technologies into one integrated system.

In order to realise the first offgrid housing project of more than 50 houses we are already working together with several key partners in different areas. 

We have assembled all the affordable and efficient housing manufacturers which can be found in our catalog and website www.wonenvooriedereen.com. With Wonen in Hout, Tiny Rebel Houses, Tiny House Store we work more closely and they are amongst our preferred partner for housing and for very efficient lighting Primalume is our partner. They are part of TWP 1. 

Regarding renewable energy Flower Turbines  (TWP 2) and for energy storage Offgrid Power Station ( TWP 3) are already our partners. When it comes to water collection and usage ( TWP 6) Rain Tanks is the partner and for nature solutions for water filtration and re-use Eduard van Vliet is the expert. 

Our goal is to find key partners in each area of the offgrid housing chain, so that we can share knowledge, create sales and above all realise the offgrid housing projects together. 

We will find and recruit partners for TWP 4, 5, 7 , 8, 9 and 10. So that we can share knowledge, create sales and awareness for offgrid housing and more, 

We will share with you our primary candidates for TWP.
