Welcome to the Ice Box Challenge LA
6 – 13th September 2018
Net Zero Conference
Electrical Training Institute, Commerce, California
Take the #IceBoxChallenge and discover the benefits of high performance building and construction. Great prizes to be won!
About the Ice Box Challenge
The #IceBoxChallenge is a contest and an experiment to demonstrate how a home can be super energy efficient AND comfortable. The Ice Boxes are left outside in the sun for 7 days. When they are opened, the amount of ice left in each box will be measured. How much ice is left shows how well each Ice Box keeps out the summer heat. Better building design can help us reduce our carbon pollution without changing our behaviour. Energy-efficient homes are comfortable, quiet and healthy.
Why High Performance Buildings?
Quite simply, it’s how we build & feel better.
High-performance buildings are reliable, affordable, comfortable buildings that use energy efficiently, so you’re heating or cooling only your home and not the outdoors. They stay comfortable and quiet throughout the year, including through summer heatwaves, winter storms and power outages. The buildings use up to 90% less energy for heating and cooling than other buildings do, while maintaining good indoor ventilation and air quality. They are easy to maintain. They are also affordable to build, own, live in and work in.
About the Design
The Ice Box Challenge was made to represent two standards of construction-
The Code Box has been built to meet the 2016 California Energy Code prescriptive measures for the respective climate zone. As California quickly ramps up their energy efficiency requirements, this design includes 2×6 insulated walls with 1″ continuous exterior insulation, and an insulated, vented roof. The windows were selected to meet the prescriptive measures as well.
The Passive House box is built based off of designs for Certified Passive House Projects in the region. Because Passive House is a performance based standard rather than a prescriptive standard, there is no one single design to satisfy the performance requirement. The box was built with well detailed insulation inside the 2×6 walls, 2″ of continuous exterior insulation which also runs continuously below the insulated floor and insulated roof, avoiding any chance for a thermal bridge. This box was completely sealed with both an interior and exterior air tightness membrane that was fully taped at all joints, providing air control to meet the strict Passive House standard. The windows are certified as thermal bridge free and provide the air tightness needed to meet the standard.
The challenge is provided by Passive House California. A Passive House approach is rapidly becoming a favoured and well-understood method of achieving high performance building enclosures in California and beyond.
The Icebox Challenge is organized in partnership with the Net Zero 2018 Conference (NZ18), and the boxes will be displayed at the Net Zero Conference location, the Net Zero Plus Building of the Electrical Training Institute in Commerce, CA. The Net Zero Conference is an affiliate event of the Global Action Climate Summit. The results of the Icebox Challenge in Los Angeles will also be relayed in San Francisco during the Global Climate Action Summit through the Global Alliance for Buildings & Construction
