The sustainability of facilities is a key component of contemporary business operations. It describes a facility's capacity to satisfy its present and future requirements without endangering the environment or the welfare of its users. Facility sustainability can improve an organization's performance, reputation, and financial success while also lowering its operational costs and environmental impact.

Energy efficiency is one of the most important aspects of a sustainable facility. The term "energy efficiency" refers to the use of less energy to produce the same or better levels of output or service. A facility's comfort, security, and productivity can all be increased through energy efficiency, which can also reduce greenhouse gas emissions and energy costs. 

Energy efficiency programs can help reduce electricity use in buildings by up to 30%, per the U.S. Environmental Protection Agency's handbook.

In this blog post, we will explore some of the strategies that facility managers can implement to improve their facility's sustainability through energy efficiency. These strategies include:

• Energy audits
• Energy management systems
• Efficient lighting
• Optimized HVAC
• Improved building envelope
• Renewable energy
• Sustainable water management
• Employee education

Let's dive into each of these strategies in more detail.

Conducting Energy Audits and Assessments

An energy audit or assessment is the first step in raising a facility's energy efficiency. A facility's current energy performance and consumption are evaluated systematically as part of an energy audit, which also identifies opportunities for energy savings and problem areas. Facility managers can benefit from an energy audit by:

1. Measure energy usage and costs
2. Compare to similar facilities
3. Identify energy-saving measures
4. Estimate savings and payback periods
5. Develop an action plan and budget

An energy audit can be done by an internal team or consultant, depending on the facility's size, complexity, and resources. The level of detail depends on the manager's goals, scope, and budget.

Implementing Energy Management Systems

An energy management system (EMS) is a software-based tool that continuously tracks and evaluates a facility's energy consumption. Facility managers can benefit from an EMS by:

• Track and visualize energy usage.
• Detect and fix problems.
• Optimize equipment and systems.
• Generate reports and alerts.
• Evaluate efficiency and ROI.

An EMS can also be integrated with automated controls to adjust equipment settings based on data. For example, it can turn off lights when no one is present or adjust the temperature based on occupancy.

Upgrading Lighting Systems for Efficiency

One of the main energy consumers in a building is lighting. The U.S. Department of Energy (DOE) estimates that 17% of all the electricity used in commercial buildings in the country goes towards lighting. As a result, improving lighting systems for efficiency can have a big impact on cutting costs and energy use in a facility.

LED lights are more efficient, durable, versatile, environmentally friendly, and aesthetically pleasing than incandescent lights. They can save up to 75% energy, last up to 25 times longer, and provide better quality and color rendering.

To upgrade lighting systems for efficiency, you can implement lighting controls and occupancy sensors. These can save up to 30% of energy compared to conventional lighting systems. Lighting controls adjust brightness and color temperature based on factors like daylight, task, and mood. Occupancy sensors turn lights on and off based on presence or absence.

Optimizing Heating, Ventilation, and Air Conditioning (HVAC) Systems

HVAC systems account for 40% of energy use in commercial buildings. Optimizing them for efficiency can reduce energy consumption and costs. One way to do this is to upgrade to energy-efficient HVAC equipment. Energy-efficient HVAC equipment can include:

• High-efficiency heating and cooling equipment
• Variable-speed fans and pumps
• Energy recovery ventilators
• Low-flow or high-performance air filters
• Programmable or smart thermostats

Another way to optimize HVAC systems for efficiency is to implement programmable thermostats and zoning controls. Programmable thermostats and zoning controls save energy by adjusting the temperature based on time, day, season, and occupancy. They can save up to 20% on HVAC costs.

Enhancing Building Envelope and Insulation

The building envelope is the physical barrier that separates the indoor and outdoor environments of a facility. The building envelope includes the walls, roofs, windows, doors, and floors of the facility. The building envelope plays a vital role in maintaining the thermal comfort and air quality of the facility, as well as preventing heat loss or gain through conduction, convection, or radiation.

One of the ways to enhance the building envelope and insulation is to seal air leaks and insulate walls and roofs. Air leaks and uninsulated walls and roofs waste energy and can cause health problems. Sealing leaks and insulating walls and roofs can save up to 30% of energy.

Increasing the thermal efficiency of windows and doors is another way to improve the building envelope and insulation. The main places where heat enters or exits a building through radiation are windows and doors. Windows and doors can also have an impact on a building's ventilation and access to natural light. Enhancing windows and doors' thermal performance may involve:

• Replace single-pane windows with double- or triple-pane windows.
• Apply low-E coatings or films to windows.
• Install window treatments.
• Replace old or damaged doors with new or weather-stripped doors.
• Install storm windows or doors.

Energy-efficient windows and doors save 25% on energy costs.

Promoting Renewable Energy Integration

Renewable energy, such as solar, wind, hydro, biomass, or geothermal energy, is energy derived from naturally replenishing sources. A facility's reliance on fossil fuels and grid electricity can be lessened by using renewable energy, which can also provide clean, sustainable, and green power for the facility.

One of the ways to promote renewable energy integration is to install solar panels or wind turbines for on-site generation. Solar panels and wind turbines capture energy from the sun and wind to generate electricity. This can reduce a facility's electricity demand, greenhouse gas emissions, and energy bills.

Another way to promote renewable energy integration is to utilize renewable energy purchase agreements (PPAs). PPAs allow facility owners to buy renewable energy at a fixed rate from providers without investing in installation or maintenance. This can provide price stability and cost savings over time.

Encouraging Sustainable Water Management

Water must be used wisely and responsibly because it is a limited and precious resource. Facility managers can take a number of actions to save water and use it more effectively. 

One of the simplest and most cost-effective ways to save water is to install water-efficient fixtures and appliances, such as low-flow faucets, showerheads, toilets, and urinals, as well as aerators, sensors, and timers. Water-efficient fixtures and other measures can reduce water consumption by up to 50%. Examples include repairing leaks, adjusting water pressure, and using water-efficient landscaping.

Another way to reduce the demand for potable water is to utilize alternative sources of water, such as rainwater and greywater. Rainwater harvesting collects rainwater from roofs, gutters, and other surfaces for non-potable use. Greywater is wastewater from sinks, showers, bathtubs, washing machines, and dishwashers that can be treated and reused. Both systems can save water, reduce runoff, and lower bills.

Educating and Engaging Employees in Sustainability Efforts

All employees who work in the facility are accountable for energy efficiency and sustainability, not just facility managers. As a result, it is crucial to inform, involve, and motivate employees in sustainability initiatives as well as to promote the adoption of energy-saving behaviors and best practices. Among the methods for doing this are:

Facility managers can promote energy-saving behaviors and best practices among employees by providing them with clear guidelines, incentives, feedback, and recognition. Businesses can save energy by asking employees to turn off lights, adjust thermostats, use natural light, print less, carpool, and participate in energy audits.

Facility managers can also conduct training and awareness programs on sustainability for employees to increase their knowledge, skills, and motivation to save energy. Programs can include workshops, seminars, webinars, newsletters, posters, videos, games, quizzes, or contests on energy efficiency, sustainability, environmental impact, renewable energy, green products, success stories, and best practices of successful facilities. You should also ensure that the employees learn about Current facility management trends so that they can also educate themselves with the facility management best practices and improve facility sustainability. 

Energy efficiency strategies that increase facility sustainability are advantageous for both the environment and the bottom line. 

Facility managers can reduce their environmental impact and generate cost savings by implementing energy-saving measures like upgrading HVAC and lighting systems, installing renewable energy systems, upgrading HVAC systems, optimizing building automation systems, encouraging sustainable water management, and educating and involving staff in sustainability efforts. 

Additionally, they can strengthen their image as ethical business leaders who care about their neighborhoods and the next generation.
