Multi-Tenant Buildings: Making Space for Energy Efficiency

Key Points Investing in energy efficiency increases asset value and makes available space more attractive. A phased approach to efficiency upgrades can help with financing and reduce tenant inconvenience. Optimizing energy savings requires a collaborative effort between property managers and tenants. Maximizing profits is often a primary goal of building owners and managers, so investing […]

Restart Your Motor Policy

Key Points An effective motor policy can save money on repair and replacement, and improve your productivity. Planning is essential. Start with an inventory of all equipment and a list of trusted suppliers. Include replacement guidelines and repair specifications, as well as preventive maintenance. Motors are critical to operations and they make up half of […]

Blow the Lid Off!

Save thousands of dollars a year by maintaining your compressor. Good maintenance practicesEnergy use may account for up to 90 percent of the total costs for compressed air production. If a system is not operating at peak efficiency, energy consumption goes up as air leakage and pressure drops occur. A preventive maintenance program will help […]

Conserving Water Helps Reduce Fuel Costs

Key Points A water-efficiency program is an excellent way to reduce your water heating bill. High-efficiency plumbing fixtures, appliances, and other equipment can yield savings on water, sewer, and energy bills. Landscape irrigation can be a significant source of water consumption during the growing season in some climates. Water heating is a significant source of energy […]

Save Energy with Intelligent Refrigeration Controls

Key Points Refrigeration controls save energy by matching equipment operations to system needs. System components run more efficiently, based on input from sensors and control instructions. Controls not only save energy, they also help to reduce demand charges and extend equipment life. How refrigeration controls work Refrigeration systems are critical to a wide variety of industries, […]

Direct Digital Controls

Key Points Direct-digital control has replaced conventional control technology in energy management systems. The system architecture maps out the system and allows controllers to share data. The advent of online control has increased the flexibility and capabilities of EMS systems. Energy management systems (EMS) have long been used to control energy use in heating, ventilating […]

Saving Energy on Computer and Office Equipment

Key Points Today’s computers are much more energy efficient than a decade ago, but only if they are configured to sleep when they are not in use. Flat screen monitors use considerably less energy than cathode ray monitors. Chargers that are left plugged in when not in use still draw current and waste energy. According […]

8 Ways to Pump Up the Savings

Key Points Pumping systems account for about 80 percent of electricity used for water treatment. Proper sizing, maintenance and improved controls can optimize pump system efficiency. Replacing valves or improving flow can help reduce friction losses and increase energy efficiency.   Publicly owned water supply and wastewater treatment plants use nearly 70 billion kilowatt-hours (kWh) […]

Save Money with Variable Frequency Drives

Key Points VFDs save energy by adjusting motor speed to match load requirements. Motors that drive variable loads, such pumps and fans, are ideal candidates for VFDs. VFDs have limitations that make them unsuitable for certain applications.   Motors are designed to operate at a constant speed. However, the devices they operate frequently run at […]
