Haus is an example of how
a 90-year old building can be both beautiful and ultra energy efficient. We kept the original footprint of the
3-bedroom, 2-bathroom California bungalow originally built in 1922. During 2012 it was retrofitted to
Passive House standards with the aim to combine extreme energy efficiency and
comfort of Passive House with the aesthetics of Arts and Crafts style.
Passive Houses stay
at a comfortable temperature year round with minimal energy inputs. Buildings make efficient use of the sun
and heat recovery so that conventional heating systems are unnecessary. The materials and systems are modeled
to a stringent performance standard using PHPP (energy modeling software) that
aims to limit the annual energy
demand for primary heating and cooling of the house 15 kWh/m2 (1.4kWh/ft2
or 4.75kBtu/ft2) per year.
This energy target is about 80% less than what conventional homes use for heating and cooling.
