Dos and Don’ts to Save Energy This Winter | Empire State Realty Trust
December 11, 2025
Temperature changes create opportunities for individuals to make sustainable decisions with powerful results. There are many ways to practice sustainability during the cold months that will not only reduce your energy consumption but will save you money in the long run. Even the smallest steps have a great impact on energy consumption, can deliver thermostat energy savings, and can support the broader efficiency goals shared by Empire State Realty Trust and its tenants.
ESRT is recognized as an industry leader in healthy, energy-efficient buildings. Its portfolio is 100% carbon neutral, powered by renewable wind electricity, and consistently ranks among the nation’s most sustainable. ESRT’s team of sustainability experts – led by Dana Robbins Schneider, SVP, director of energy and sustainability – provided some dos and don’ts for individuals to save energy this winter.
Check out Dana’s tips below!
Do Lower Your Thermostat
Even a slight reduction in temperature can create meaningful thermostat energy savings. A temperature range of 67-70 degrees is ideal during the winter months to conserve energy. Encourage employees to keep an extra layer, like a sweater or jacket, to avoid overreliance on building heating systems.
Don’t Use an Electric Heater
Though they may seem like a simple option, electric heaters are highly inefficient, costly, and create safety concerns. They also increase plug load, which can impact your office’s overall energy performance. Instead, take advantage of natural heat gain: keep window shades or curtains open during the day to let in warm sunlight.
Do Use Public Transportation
When it’s too cold to walk, public transportation is an efficient, environmentally friendly way to get around. Reduce the amount of energy produced by individual cars – and save on gas money! – when you ride the bus or train. ESRT’s properties provide convenient access to major transportation hubs to make sustainable commuting easier for tenants.
Don't Forget to Turn Off Unneeded Lights or Appliances
Small appliances, chargers, and adaptors that are left plugged in can still consume energy throughout the day. Make sure you flip off the lights when you leave a room, unplug devices until they are needed, and set monitors and computers to enter sleep mode after inactivity.
Do Switch to Energy Efficient Lightbulbs
When it’s time to replace your lightbulbs, consider a switch from traditional incandescent lightbulbs to eco-friendly versions like LEDs, halogen incandescent, or compact fluorescent lamps. ESRT has completed LED retrofits across the portfolio, and tenants can request support to align their in-suite lighting with these standards. ENERGY STAR certified lightbulbs will last longer and can save you between $30 and $80 in electricity costs over the bulb’s lifetime!
Don't Rely on Single-Use Items
Reduce the need for single-use plastics like water bottles, utensils, and containers when you invest in reusable ones. If you must use single-use items, recycle and compost to reduce your environmental impact.
Do Keep Radiators Unobstructed
Make sure that radiators are not covered by curtains, blinds, furniture, or any other objects. These items can prevent the spread of heat throughout the room and make heating equipment less efficient.
