Thermal comfort

Thermal comfort

The US industrial sector uses more than one-third of all the energy consumed throughout the country, most of which comes from natural gas and petroleum.[1][2] Heating, ventilating, and air conditioning (HVAC) systems account for between 40 percent and 60 percent of this energy use in the commercial sector,[3] making it the largest business energy drain.[4] In fact, heating and cooling energy use can account for over 30 percent of a business’ typical operating budget, while adding 20 percent to America’s total greenhouse gas emissions.[5]

Burning fossil fuels like natural gas and petroleum creates several environmentally harmful gasses, including carbon dioxide (CO2), which is the most predominant greenhouse gas; methane (CH4), a less common but more potent greenhouse gas; nitrogen oxides (NOx), which contribute to smog and acid rain; and sulfur dioxide (SO2), which has been linked to several respiratory problems as well as acid rain.[6] Additional downsides to developing petroleum and natural gas include disruption of land and ocean habitats, oil spills which can kill wildlife, and pollution of water supplies.[7]

Studies done by the National Institute of Standards and Technology have shown that improvements in windows and insulation are very cost effective, providing potential reductions in heat loss greater than 50 percent, reducing energy use by the same amount, and increasing comfort levels significantly.[8] Improved thermal comfort can also reduce costs by increasing employee efficiency, in some cases as much as 3.5 percent.[9]

Questions to get you started...

  1. Do you own or lease the office space? Do you pay for energy or does your landlord handle the bill?
  2. What is the total annual energy bill?
  3. How is temperature controlled? By individual thermostats or by entire floors?
  4. Are programmable thermostats installed to control heating and cooling systems?
  5. Have you checked your building for air leaks around windows and doors? Are draft stoppers in place?
  6. What is the total area of office space?
  7. Can you upgrade your windows with double-pane options or window films?
  8. Have you established an energy management system to track energy use and reduce energy costs? Do you regularly tune-up your HVAC system?
