    Data Logger Basics

      New

    In today's data-driven world of satellite uplinks, wireless networks, and the Internet, it is common to hear the terms "data logging" and "data loggers" and not really have a firm grasp of what they are.

    Most people have a vague idea that data logging involves electronically collecting information about the status of something in the environment, such as temperature, relative humidity, or energy use. They're right, but that's just a small view of what data logging is.

    In the fields of building performance and environmental research, everyone seems to be using data loggers. Butwhat are they, and why are they useful?

    This guide will introduce you to the wide world of electronic data loggers and data logging.

    Monitoring Green Roof Performance with Weather Stations

    Data logging weather stations are the ideal tools for documenting green roof performance. A weather station can measure weather parameters such as rainfall, stormwater runoff, temperature, relative humidity, wind speed, solar radiation, and a host of non-weather parameters such as soil moisture on a continuous basis (say every five minutes, hourly, or an interval appropriate to the situation). For the purpose of this discussion, “weather station” may refer to a data logger that measures and stores data from weather sensors. The information a weather station collects can help you make wise choices about designing, tuning, and maintaining a green roof.

    This guide will explain how a weather station can be a valuable component of a green roof project, and will share information particular to this type of application.

    Using Data Loggers Beyond Equipment Scheduling

    While data loggers are a great tool for identifying equipment-scheduling opportunities in buildings, their usefulness far exceeds just that one function. This paper discusses how the use of inexpensive data loggers and some spreadsheet analysis can provide all the evidence needed to make powerful building-specific cases for saving money by replacing failed air-handler economizers. It also describes how information from data loggers can be used to accurately calculate the energy savings that can be realized from variable frequency drives (VFDs) on pumps and fans, supply air resets, and boiler lockouts

    Analyzing Air Handling Unit Efficiency with Data Loggers

    Operating a heating, ventilation and air conditioning (HVAC) system at optimum efficiency in a commercial setting is complicated, to say the least. There is a very real chance that any number of setpoints, levels, and feedbacks at boilers, chillers, pumps, fans, air delivery components and more can cause costly inefficiencies.

    This 20-page guide, Analyzing Air Handling Unit Efficiency with Data Loggers, explores the air handling systems of an office building to illustrate how data loggers can be used to help optimize their performance. The guide provides 13 best practices for improving air handler efficiency and reducing costs, while maintaining a comfortable working environment for building occupants.

    Finding Hidden Energy Waste with Data Loggers: 8 Cost-Saving Opportunities

    The first step to reducing building energy costs is identifying energy waste. Statistics on utility bills or name plates on equipment, while useful, are not enough to identify what practices and equipment are contributing to high energy use. Portable data loggers can be used to obtain critical energy use information in a wide range of commercial building types – from manufacturing plants to office buildings. This 12-page best practices guide, Finding Hidden Energy Waste with Data Loggers, describes the data logging equipment you need to obtain information on energy consumption and environmental conditions in commercial buildings. It covers eight common forms of energy waste, and provides an overview of how to gather and analyze data and calculate savings for each opportunity.

    Monitoring HVAC Performance with Data Loggers

    Building operators and managers have the difficult job of providing comfortable working conditions and coaxing aging mechanical equipment to operate at peak performance while minimizing energy costs. If the mechanical equipment is old or has inadequate controls, maintaining comfort at a reasonable cost may prove difficult or impossible. Although energy costs typically represent only 1% of a building’s operating expense when occupant salaries are included, they are easily managed expenses. Energy cost savings flow directly to the bottom line as increased profits.

    Monitoring Wetlands with Data Loggers: A Best Practices Guide

    Wetlands act as a natural filter for polluted water and thus play an essential role in water quality protection. They serve as floodwater storage to help minimize erosion, and create a habitat for many fish and wildlife.

    While a variety of factors have decreased the number of wetlands in the U.S. by half since 1950, many organizations are restoring wetlands back to their original flourishing ecosystems. To ensure success, it is necessary to monitor wetland factors such as water level, temperature, and rainfall.

    This guide shares field-proven best practices for configuring, launching and deploying portable data loggers in wetland monitoring applications. A range of data logger types is covered, and tips are provided on logger installation and maintenance.
