Event Description

Midori Haus is participating in the International Passive House Days this weekend.

What is Midori Haus  Midori 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.

What is Passive House?  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.
