EpiPHany Corner | PH Envelope Elevates the Impact of other Efficiency Measures

Passive House protocols, when applied to the design and construction of a building, will dramatically reduce the energy required for heating and cooling. This reduced energy for heating and cooling lowers the overall energy use significantly. As a result, the amount of energy used for water heating, lighting, refrigeration, appliances/electronics (plug loads) become more impactful and more important to manage. Consider the example below.  The Pie Chart on the left…



How does a 10% change in efficiency have a 100% impact?

“Value engineering” is a term that is familiar to those involved in the design and construction of buildings and generally involves the substitution of a specified component or system with an alternative solution that is similar, but less expensive. Consider the following: A building is designed to include a heat recovery ventilation system (HRV) in order to provide a balanced exchange of continuous fresh air to the occupants and, at…


How is a Firefighter’s “Protective Gear” like a Passive House?

How is a Firefighter’s “Protective Gear” like a Passive House? We are all aware of wildfires here in California — and grateful for the thousands of Firefighters who risked their lives battling those wildfires. They put themselves in environments where they need to be protected from the extreme heat, winds, and unhealthy air full of smoke and other pollutants. Fortunately, they are kept safe “inside” of their personal equipment (PPE).…


Advocates for efficient homes set a goal of building 1,000 units in Monterey County by 2030.

Article in the Monterey County Weekly features Sky Ranch Passive House written by Pam Marino, photo by Parker Seibold. When Jay Gentry was a young man he thought he was called to the ministry, but it didn’t quite work out as a career choice. Yet Gentry is a natural evangelist, and today he preaches but not from a pulpit. His message is about the need to combat the climate crisis through building…


The “Duck Curve” – What it is – Why You Care

The intent here is a simplified explanation of how and why our patterns of electrical usage create issues for utilities, how rooftop solar impacts those issues, and how energy storage helps solve them. Think “Duck Curve for Dummies”. Two important facts about electricity are important to the explanation. First, electricity must be used as it is generated. A limited amount can be stored in batteries but it cannot be compressed…
