![]() LightingĪccounting for approximately 40% of total electrical energy use in office buildings on average, lighting systems can be made more efficient through measures such as using energy-efficient lamps and ballasts, incorporating reflective devices, and implementing daylight controls. Major energy-consuming components include lighting, office equipment, and motors. In most commercial and industrial facilities, electrical energy costs constitute a significant portion of the utility bill. Thermal bridges, if present, should be addressed promptly to prevent increased heat transfer and moisture condensation, which can compromise the envelope's integrity. Nevertheless, auditing envelope components is recommended to identify energy-saving potential and ensure structural integrity. Mitigation of leakage areas through cost-effective weather-stripping techniques, especially crucial for residential buildings where weather-related energy consumption is predominant.įor commercial buildings, improvements to the building envelope may not always be cost-effective due to their potentially high expense. Installation of energy-efficient windows (high R-value, low-emissivity glazing, airtight, etc.) to reduce energy usage and enhance indoor comfort. Addition of Thermal InsulationĬost-effective for surfaces lacking thermal insulation. Additionally, observations regarding repair needs and recent replacements should be noted.Ĭommonly recommended ECMs to enhance the thermal performance of the building envelope include: 1.1. During the survey, comprehensive information about the materials of construction (e.g., insulation levels in walls, floors, and roofs) and the specifications of various envelope assemblies (e.g., window types and pane numbers) should be documented. ![]() ![]() The energy auditor should ascertain the actual characteristics of the building envelope. The building envelope, comprising walls, roofs, floors, windows, and doors, significantly impacts a facility's energy consumption. Moreover, ECMs should be recommended only after performing an economical analysis for each measure. However, it is strongly advised that energy auditors keep abreast of new technologies that can enhance facility energy efficiency. Rather, it is provided to indicate options that energy auditors can consider during energy analyses. It should be noted that the list of ECMs presented below is not exhaustive or comprehensive. In this subsection, various energy conservation measures (ECMs) commonly recommended for commercial and industrial facilities are discussed.
