Hotel Solar Thermal Study – Part 3: Finance and Design

  In Part 2, we discussed how to measure hot water consumption and hot water energy use in a mid-sized hotel.  We looked at what the data meant regarding the energy saving potential of a solar thermal water heating system.  This particular hotel uses about 572,500 BTU per day and spends an estimated $6,070 per…

Hotel Solar Thermal Study – Part 1

Recently, I have been conducting research on optimizing solar thermal water heating systems for hotels.  Hotels are among the best sites for solar domestic hot water (SDHW) systems because of their large and constant hot water load (a third of the energy used in hotels is for heating water!), and because their roofs are typically…
