Building evaluation should change 1/2

20 maart 2023admin
bouw-tek-untitled

There is a lot of discussion in the Netherlands about how to assess buildings, if you integrate material impacts in addition to energy, as well as to somehow include CO2 budgets. There is already an instrument for this, the MPG,… Continue Reading →

tipping-_030

Of course, it makes some sense, improving our house with some insulation, a heat pump and so on (or not, I’ll come back to that soon!) , but if you could choose where to live or build, or move, where… Continue Reading →

nieuwe-terpen-overdiepse_polder-1-antraciet-1200x848

I was asked that question last year by Thomas van Belzen of Cobouw,[1] and it got me thinking. It was an interview in Dutch, but let me return to it in English and in more detail at the beginning of… Continue Reading →

It is common in construction to normalize per m2 floor: such as e.g. energy, material, ventilation needs, or even costs and investments. But when it comes to the national requirements for housing in fact you should not calculate per m2… Continue Reading →

MNB1: 0-CO2 per 2030, MNB2: max 550 kg/m2

natuurhuis-strotec

Last week, two interesting reports were published analysing how regulations can better support ‘sustainable’ material use. Very esteemed colleagues, united in a Dutch ‘Gideons tribe’ to make the buildings sector move faster, have been working on this. [1] I can… Continue Reading →

The Bionological House

7 maart 2022admin

With vegetables, we’ve been doing it for years: most current vegetables never existed, in an autonomous evolutionary process. We as humans have slowly transformed them so that they grow the way we appreciate them, and want them on our plates.… Continue Reading →

Carbon storage in wood-timber 1/2

14 februari 2022admin
co2-protest_1372397i

Storage (binding) of CO2 in wood/timber is a hot issue at the moment*. But how should that be calculated really? Before I go into more detail, a few preliminary remarks: (the part on ‘calculating’ has been later added, and ‘CO2’… Continue Reading →

Two Demolition cranes demolishing old row of houses in the Netherlands

Life has an end, but is there also an ‘end of life’, for products and buildings? Which is frequently used in science, like in building evaluations calculating with a maximum life span, but seems weird. It is understandable in trade,… Continue Reading →

Last week I published a letter in the Netherlands, in which I indicated that about 800,000 hectares of land would be needed for the construction of new homes. That’s how it works in a transition: We have to significantly reduce… Continue Reading →
