How Much More Will a High Performance Home Cost?

Corbett Lunsford

The answer to this bass-ackwards question is: NEGATIVE DOLLARS AND ZERO CENTS. It costs LESS to build a high performance home, whether that means ENERGY STAR Home, a Passive House, a Zero-Energy Ready home, or any of a number of other green home certifications.  Here's why:

In his first Fall Fast Track week of 2015, home performance guru Corbett Lunsford answers the question "how much more will it cost to build my next home high performance?" The answer to the question is as straightforward as the question is ridiculous!

Engineering a TOURING Tiny House: See the Full Series

Corbett Lunsford

Grace and Corbett are building a performance-proven tiny house on wheels called the Tiny Lab! It's going to be built from November to February, and it starts a 16-city US Tour in March of 2016. The Crowd Sourcing Campaign is happening NOW on RocketHub- CLICK HERE TO PARTICIPATE IN THE TOUR! Here's the full series of four webinars from August 2015 detailing the engineering of a super cool tiny house on wheels!

In #1: SHAPE AND LAYOUT, Corbett and Grace show the 3D sketchup model of the Tiny Lab, and bring engineer John Bergman in for some heavy lifting to do with pinpointing the center of gravity on this 24 ft trailer tiny house.

In #2: AIRSEALING, INSULATION, & WEATHER BARRIERS, tour the process of energy modeling the tiny house to determine the optimal R-values and level of airtightness, and hear about vapor barriers, moisture control, and drainage.

In #3: HEATING, COOLING, AND VENTILATION, you get a taste for how wrong a lot of the discussion goes about homes in general, and tiny homes especially. The HVAC design, including Manual J heat load calculations and hourly solar gain curves are analyzed and used for things as straightforward as deciding which direction to park the tiny house.

In #4: BELLS & WHISTLES, see behind the design of the solar PV kit, formaldehyde-free plywood built-ins, composting toilet, off-grid plumbing challenges, and luxury items that just add that quality of life that tiny house occupants are seeking.

We really hope you'll tune in for the videos of construction- you can subscribe to our YouTube channel right now with one click!
