For rent

Almost all windows have 3 double glazing. The walls have 20 cm wall insulation made of wood fibreboard, of which 14 cm outside and 6 cm inside; Floor insulation inside: the living room floor has 2 types (tone-sun foil and Styrofoam balls); the basement is very well insulated; Roof insulation: 14 to 20 cm PIR foam; the roof is also covered with sedum Solar energy generation: 10 solar panels are installed. The first 60 cm of the ground are also insulated, so that the insulation lies like a tea cosy over the house and even goes down to the ground. The heat is stored in the insulation during the day and released in the evening. The only disadvantage is that it can get extra warm in the summer. By closing the shutters on the south side from 10 to 11 a.m. and airing them in the evening and at night (windows are fitted with mosquito nets) you keep the house reasonably cool. Max 28 degrees. In winter, when the sun does not heat the living room (the house is facing south), it can feel fresh. The house loses its warmth at night because of the windows. Even though they are 3-layer, they insulate less well than the walls. Curtains help a lot, and in the living room I also have duette pleated curtains. Theyalso help to keep the heat inside. It also helps a lot if you dress warmly. Insulate your body! With all these measures I think it’s a lovely house to live in.

(more about infrared heating, advantages and disadvantages according to ThermIQ). There are no radiators, no central heating boiler, not even a gas connection: your body is heated by infrared panels on the ceiling.

In the living room a heat recovery system (WTW) continuously refreshes fresh air. In this process, 88% of the indoor heat is recovered. Brand Zehnder. More about the WTW

A CO2 meter on the table measures the amount of CO2 in the air, displays this as a number. It sounds an alarm if the CO2 concentration exceeds 1400 ppm. In that case you have to turn off the alarm and take one of the following measures.

• Put the WTW in a higher position
• open the door to the hallway
• open a window

Half an hour after switching off the alarm, the CO2 meter measures again and hopefully you have taken adequate measures. Otherwise it will go off again and you will try another measure. A high concentration of CO2 means that there is too little oxygen in the air, which can cause headaches.

Draughts cause the air to rub against your skin. In the summer it is just lovely and opening doors and windows helps to cool down

Look online at my account at Enelogic (included in rent) how much energy you use and how much the 10 solar panels generate (especially in summer).
What difference does it make if, for example:

• closes the shutters or keeps them open at night (in summer the 3 shutters on the south side really keep out a lot of heat)
• the duette pleated curtains closed versus open (pleated curtains with alu coating in living room south side and bathroom)
• temperature in the hall increases
• cooking method: see Pierre Wind’s tips (discussion by me of Pierre Wind’s eco-kitchen, 2020). The book is in the kitchen.

In the front and back garden is plenty of fruit and herbs; see https://eetbaarnijmegen.nl/moestuin/stadstuin/
There is a high vegetable garden container to sow in yourself.
You can use the shed to grow plants in, after pre-sowing indoors. I did this with tomatoes, pumpkin, courgettes.

I intend to come back to Nijmegen once in a while and then I could maintain the garden; help solve problems.
