UTCI
Heat Index
UTCI, or Universal Thermal Climate Index, measures the heat stress on the human body induced by a set of climatic conditions – including air temperature, humidity, wind, and radiation.
Heat Index (HI) is another measure of heat stress that uses relative humidity and dry bulb temperature to deduce the likelihood of heat disorders with prolonged exposure or strenuous activity . The metric is based off the National Weather Service’s (NWS) heat forecast tools. For each timestep in the climate file, the HI heatmap gives an indication of date, time, temperature, and a heat index of either no risk, caution, extreme caution, danger, or extreme danger.
These glare calculations are based on the Daylight Glare Probability (DGP) metric, developed by Wienold and Christofferen

PE and CO2 emission references `ANSI/ASHRAE/ICC/USGBC/IES Standard I89.I-2020`_ Table 7.5.2 Source Energy Conversion Factors and CO2e Emissions Factors. and Table 5-2b Primary Energy Conversion Factors
Prices are highly volatile and region dependent. Our values reference NYSERDA energy annual prices. Default prices are from New York State Residential Energy Prices in Nominal Dollars from the year 2018 with the exception of Coal and Gasoline prices. Coal price is from 2007 adjusted to 2018 dollar value based on GDP deflator. The gasoline price is from 2022 New York State Weekly Motor gasoline prices for Dec. 2022 Statewide converted into $/kWh based on the assumption of 113.45 btu/gallon energy density of Gasoline as reported by National Service Center for Environmental Publications Fuel Economy Impact Analysis of RFG.
Diesel is assumed to be equavalent to Fuel Oil (distillate) from ASHRAE table.
Wood Pellets The PE factor is assumed to be 1.1 and the CO2 conversion factor is assumed to be 0 (wood from sustainable sources with 0 carbon emissions).
