That's why a continuous ventilation is so useful to have in winter. Our indoor RH vs outdoor RH readings for this month for info, running a continuous MVHR system

80 or 90% Relative Humidity outside in winter is still lower in absolute terms when compared with 60-70% RH indoors, it's linked to temperature

Enjoyed a stroll around sunny Bristol yesterday. Brunel riding a Brompton was probably my favourite

We’ve used the leaves as a cosy blanket for our recently sowed wildflower meadow. Fat balls next…

Why is it that drivers of 4x4 SUVs feel invincible to drive through floods?

Rustenburgstraat is a development of 89 homes for a social housing provider 'Trudo' in Eindhoven/ The Netherlands 🇳🇱

Built with pre-assembled EcoCocon straw wall system 🌾

This is how to normalise construction with biobased materials

Made the most of Passivhaus Open Days and visited Malvern Passivhaus today. High performance timber frame prefab and 0.13ACH blower door test result - impressive work by Forest of Dean based Passiframe.
