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

Apartment-installed system: installation takes

minutes and conforms to existing enclosures
