In recent years, there has been a growing emphasis on sustainability in the building industry. Building owners and managers are recognizing the benefits of reducing energy and water consumption, not only from an environmental standpoint but also from a financial one. By conducting energy audits, water audits, and recommissioning and implementing measures, building owners can save significant amounts of money on their energy and water bills.
Energy Audit
An energy audit is a comprehensive assessment of a building’s energy performance. It helps identify areas where energy is being wasted and provides recommendations for improving energy efficiency, reducing energy consumption, and saving money on energy bills. The audit typically involves analyzing energy bills, conducting an on-site inspection, and using specialized equipment to measure energy performance. The energy auditor provides a report with recommendations for upgrades to insulation, lighting, HVAC systems, and appliances, as well as operational changes such as adjusting thermostat settings and reducing unnecessary lighting. The benefits of an energy audit include saving money on energy bills, improving energy efficiency, enhancing comfort and productivity, increasing building value, and complying with regulations.
According to report by the Department of Energy, energy audits can result in energy savings of up to 30%. For example, a commercial building with an annual energy bill of $100,000 could potentially save $30,000 annually by implementing the recommended upgrades and operational changes from an energy audit. The payback period for these upgrades is typically between one and three years, meaning that the initial investment in the upgrades can be recouped relatively quickly.
Water Audit
A water audit is a comprehensive assessment of a building’s water use. It helps identify areas where water is being wasted and provides recommendations for improving water efficiency, reducing water consumption, and saving money on water bills. The audit typically involves analyzing water bills, conducting an on-site inspection, and using specialized equipment to measure water use. The water auditor provides a report with recommendations for upgrades to plumbing fixtures, irrigation systems, and appliances, as well as operational changes such as fixing leaks and reducing unnecessary water use. The benefits of a water audit include saving money on water bills, improving water efficiency, enhancing sustainability, and complying with regulations.
A study by the Environmental Protection Agency found that water audits typically result in water savings of up to 20%. For example, a hotel with an annual water bill of $50,000 could potentially save $10,000 annually by implementing the recommended upgrades and operational changes from a water audit. The payback period for these upgrades is typically between one and five years, depending on the type of upgrades implemented.
Recommissioning
Recommissioning is a process of improving a building’s performance by optimizing existing systems and equipment. It involves a systematic review of the building’s systems and equipment to ensure they are operating as intended and to identify any opportunities for improvement. Recommissioning typically involves a detailed review of building systems and operations, equipment testing and calibration, and staff training. The recommissioning team provides a report with recommendations for improving the performance of building systems and equipment, reducing energy and water consumption, and enhancing sustainability. The benefits of recommissioning include improving building performance, reducing energy and water consumption, enhancing sustainability, and prolonging the life of equipment.
According to a report by Lawrence Berkeley National Laboratory, recommissioning projects typically result in energy savings of up to 15%. For example, a university building with an annual energy bill of $200,000 could potentially save $30,000 annually by implementing the recommended upgrades and operational changes from a recommissioning project. The payback period for these upgrades is typically between one and three years.
Conclusion
Energy audit, water audit, and recommissioning are three essential tools for improving building sustainability. They provide a comprehensive assessment of a building’s energy and water performance and identify opportunities for improvement. By implementing the recommendations from these audits and recommissioning, building owners and managers can save money on energy and water bills, improve energy and water efficiency, enhance sustainability, and comply with regulations. Building sustainability is not only good for the environment but also good for business, as it enhances the value of the building and its appeal to tenants and customers. The real-world numbers show that these upgrades are not only good for the environment but also good for business.
In addition to the financial benefits, implementing energy audits, water audits, and recommissioning can also enhance the sustainability of a building. By reducing energy and water consumption, buildings can reduce their carbon footprint and contribute to a more sustainable future. This is becoming increasingly important to tenants and customers, who are placing more value on sustainability when choosing where to live, work, and do business.
