Windows – Energy efficient windows are designed to maximize solar heat gain in the winter and minimize it in the summer, in addition to lowering air leakage rates. They allow your building’s heating and cooling system to operate more efficiently.
Lights – Lighting accounts for about 23% of commercial energy consumption and compact fluorescent lamps (CFL) can save a great deal of energy. CFL lighting uses about 1/4 of the amount of energy as incandescent bulbs, so a 75-watt fixture will use just 19 watts of electricity.
Sensor Switches – There are certain areas of your commercial building that may not be in use for hours at a time, including storage rooms, meeting rooms, or restrooms. Installing motion sensor switches will keep lights off when no one is around, adding potential savings on your energy bills.
High-Efficiency HVAC – The heating, ventilation, and air conditioning systems will be big contributors to the energy efficiency of your modular building. Having regular Classic Air Conditioning and Heating Services done to the unit and constant change of HVAC filters will help to save money. Something as simple as a programmable thermostat allows you to save on heating and cooling costs after-hours or on the weekends.
Roofing Color – You might not give much thought to roofing color, beyond what looks aesthetically pleasing, but the colors you choose can affect the temperature inside your building. In warmer climates, roofing that is gray or contains flecks of white can reflect heat and prevent absorption. In colder climates, dark roofs will help snow melt faster and absorb heat.
Want to take energy-efficient roofing even further? Modular buildings can be constructed with solar panels which produce their own energy for electricity or heating.
Additional Advice for Energy Efficiency
Track your efforts using the EPA’s Portfolio Manager tool to benchmark your energy performance and cut down on your energy bills. A recent study of participants found that by tracking their efforts towards being energy efficient, they saved about 2.4% per year in energy costs. To give you an idea of how much that small percentage represents:
