Upgrade lighting systems: Installing LED bulbs and dimmers can reduce the amount of energy used Implement passive cooling measures: The energy needed to cool spaces can be reduced or eliminated through insulation, reflective surfaces, shading, green roofs, natural ventilation, and orienting new buildings to optimize shade and thermal heat gain Implement building envelope improvements: Improving the insulation and doors of buildings, and Installing double- or triple-glazed windows can reduce heat loss and heat gain. Adjust outside-air intake. Most air-conditioning systems use a dampered vent called an economizer to draw in cool outside air to reduce the need for mechanically cooled air. You can set these economizers to run only when spaces are occupied (this is known as demand-controlled ventilation). Use smart building technologies: Smart building technologies, such as building automation systems, can help to optimize the energy use and climate control of buildings and can improve the comfort and productivity of occupants. Invest in electric heat pumps: Heat pumps are a highly efficient key technology for space and water heating, and for space cooling. By replacing fossil fuel-powered boilers with heat pumps, buildings can electrify their heating process and reduce their greenhouse gas emissions. Financial incentives to cover a part of the up-front costs, as well as labeling and efficiency standards, have supported the adoption of this technology in recent years HVAC upgrades: Heating and cooling systems account for as much as 40% of the average commercial building's electricity consumption, and high-efficiency HVAC equipment can cut that amount by 30% to 50% (EPA). Decreasing the energy intensity of operations (the amount of energy used per square meter [m2] of floor area, including heating, cooling, and appliances) Commonly used energy efficiency measures: 01 — Energy Efficiency
