Now.. that would be cool 😉

Whoa! Thanks for not giving us the cold shoulder, DC 🤗 We’ve been ecstatic to call DC home these past 2 weeks. There’s sill time to take the challenge! dc.iceboxchallenge.com

Why doesn’t the Passive House Box need to turn on the air conditioning? Because it’s not a “fan” 😂😂 AND because it’s air tight thanks to @SIGA_USA air sealing tapes! #IceBoxChallengeDC #iceboxhumor #takethechallenge #FarragutSquare #buildingscience #passivehouse

It’s been two exciting weeks European Union in the U.S. as hundrends if not thousands took the #IceBoxChallengeDC guessing how much ice will be left in two buildings: 1st built to regular building code, 2nd to #passivehousedc standard. #EnergyEfficiency - key way of delivering on #ParisAgreement

There was a clear IceBoxChallenge winner today in Farragut Square! The Passive Housing box had near double the amount of ice left over than the one built to normal building codes with 838 lbs leftover from the original 1,800 lbs.

We think the loser of today’s #IceBoxChallengeDC is clear... so clear you can see right through it! The Passive House Box wins again! Thanks to our partners European Union in the U.S. Belgium in the USA Golden Triangle BID NK Architects and sponsors ROCKWOOL North America @SIGA_USA Cascadia Windows & Doors & Crux Homes

A public science experiment in D.C. tested the energy efficiency of a conventional building structure and a passive solar building structure. How much ice would remain in each building after 2 weeks? The #IceBoxChallengeDC results: bit.ly/2NMQT2O IceBoxChallenge
