While we are not experts at HVAC, here are some basic tips. For more information, please contact your HVAC professional.

In previous posts in this series, we’ve discussed green roofs and recycling programs. Today we are looking at more “behind the scenes” ways you can reduce your building’s carbon footprint.  According to the U.S. Department of Energy, commercial buildings account for 18 percent of total U.S. energy consumption. In a typical office building, energy use accounts for 30 percent of operating costs, which is the single biggest category of controllable costs. Reducing energy usage can result in significant long-term reduction of building expenses, freeing up capital you could use for other improvements such as landscaping or painting.

Today’s blog covers ways you can improve your building’s HVAC and other systems to improve energy efficiency and save on costs.

Reduce the need for heating and air conditioning:

  • Review building insulation and fill gaps with the most efficient materials.
  • Reduce the building’s “solar gain” by installing reflective roofing materials and tinted windows. These are especially important in buildings located in sunny climates.  Examine office equipment to make sure tenants use the latest technology that produces a minimum of heat. Pay special attention to data centers which require substantial cooling.
  • Simple solutions are best.
    • Encourage tenants to open blinds/curtains where feasible to let in warm sunlight.
    • Ask tenants to close/open windows to warm/cool office spaces before adjusting thermostats.

Selecting and maintaining the heat and AC systems:

  • Review older systems against more efficient, modern units. For many buildings, the initial outlay for a new system could potentially be recouped through annual energy savings. Talk to an HVAC specialist about potential savings.
  • Don’t purchase a system that is too big for your building. Your installer can test to make sure the “load” recommendation is met for your building.
  • Consider dehumidification systems for humid climates and evaporative coolers in dry climates. As the saying goes, “It’s not the heat. It’s the humidity.”
  • Install quality control systems:
    • Programmable thermostats are important for reducing heating/cooling during off hours. Work closely with facility managers to make sure thermostats are set for the correct temperature.
    • Multiple zones are essential for multi-room and multi-floor buildings. Tenants will inevitably have different needs. Some might have 20 employees working in one space, while others might have only a few employees who work in small, individual offices.
    • CO2 sensors dynamically adjust heating/cooling by measuring CO2 amounts.

Proper maintenance:

  • As with all mechanical systems, proper maintenance can extend life and performance.
  • Replace air filters frequently with high quality filters.
  • Inspect all ductwork and piping for any leaks, which can contribute to heat/cooling losses.
  • Check thermostat function to make sure everything is functioning as it should.

Beyond the benefits to the planet and your profits, improving your building’s HVAC systems will lead to comfortable, content tenants. This is great because no one likes to hear disgruntled employees complain about being too hot or cold. And an unhappy employer is a tenant who might not renew his lease in your building! Modern HVAC systems are designed to provide controlled temperatures at maximum comfort.
