Building energy use comparisons

As part of our IoT development work, MCCI and NY Passive House have been partnering to reduce the cost of monitoring buildings (both high performance buildings and conventional construction). This low-cost study identified eight-fold differences in energy intensity across a variety of buildings. By choosing buildings at the same altitude and in the same microclimate, we are able to focus on differences in construction. We started monitoring electricity use and…

PHPP + Rhino | An Introduction to IDF2PH

 The Passive House Planning Package (PHPP) is a trusted, effective tool and is critical for Passive House Certification. However in many circumstances it can be useful to pair the PHPP with a multi-zone, dynamic tool such as the US Dept. of Energy’s EnergyPlus engine which can output sub-hourly time step results. In the past, if a designer wished to utilize both of these valuable tools, that meant duplicate modeling…



We’re on a mission to collect performance and cost data from multifamily Passive House buildings in the U.S.

Why should anyone contribute to this database? In 2019, HPD, CPC, Bright Power, and Steven Winters Associates went on a mission to identify and collect performance and cost data from multifamily Passive House buildings. While Passive House has demonstrated great success for decades, there currently isn’t a database dedicated to capturing and publishing cost and energy data from Passive House projects. This lack of available data has made it challenging…
