My Apartment after RadLab
• Radiator is enveloped by an insulating media
•Heat is distributed to room by fans
• Temperature is monitored and logged wirelessly
Can radiator heating systems become more like modern systems?

• More efficient heat transfer past “hot” apartments to “cold” apartments
• No unnecessary boiler firing
•“Problem” apartment diagnosis with data analytics

Example apartment overheated to 80F
• 0.02 BTU/hr x 1 ft3 = 1 degree F / hour• 10 degrees F / hour = .2 BTU / hour x 1ft3
• Average apartment size 700ft2 * 9ft ceilings ~= 6000ft3
3000BTUs / hour saved
The RadLab system saves energy by keeping the temperature of apartments
at comfortable levels and communicating temperature data to the central
boiler. As a result, windows stay closed and the boiler only has to fire when
apartments call for heat. System intelligence can optimize the heat
distribution throughout a building for efficiency and comfort.

• 2 million apartments in NYC in building of 5 or more units (target demographic)
• Conserving 15% of this energy is equivalent to saving 34 million BTU / year
• Conserving this energy would remove 3,250 metric tons of SO2 from the air / year
• Conserving this energy would remove 375 metric tons of PM2.5 from the air / year
•
Conserving this energy would remove 2.5 million metric tons of CO2 from the air / year
Emissions
• BTU’s 17m
• SO2 3lbs
• PM2.5 0.4lbs
• CO2 3000lbs
Emissions Savings per 700ft2 Apt
15% reduction / square foot apartment space

Achievements
• Provisional patent filed through CU
• Proof of concept in my apartment
Next Steps• Pilot Study:
• Cluster of apartments that share 1 heating line
• Funding to cover hardware, installation, and maintenance
