Warm: Low Energy Building Practice


WARM: based on theory and practice. Everything we do comes down to building physics. From an airtight green-oak office to a refurbishment of a conservation property, we have continually tested our ideas on our own properties. Warm was formally set up in January 2009 by father and daughter Peter Warm & Sally Godber. Their aim – to designing buildings that demonstrated real energy savings. The Passivhaus standard hit a chord with this ambition and quickly became the mainstay of their work. Warm now specialise in Teaching, Designing, Certifying & Testing to the Passivhaus standard. Peter is endorsed by the Passivhaus Institut in Darmstadt as a certifier, so they can offer a complete package.
