Book excerpt: ABSTRACT: Buildings are responsible for 70% of the United States' electricity consumption and approximately 40% of the total U.S. energy consumption. Over the past decade, the increasing cost of energy has caused businesses to rearrange their budgets in order to perform the same functions. Efforts in reducing energy costs through Energy Efficiency Measures (EEMs) are common in the building industry, however, the range of approaches for identifying these EEMs vary depending on available funds. It is common for these businesses to invest little to reduce energy costs. The intent of this study is to compare two separately conducted energy audits and determine which one provides an effective list of EEMs to reduce the overall building operating energy costs. Using Rinker Hall as a case study building, comparisons were made between a general walkthrough energy audit and a detailed energy audit (ASHRAE level II). These audits were transformed into inputs for a dynamic energy simulation tool. Both energy models are validated with the existing energy consumption values to determine which accurately projects actual building performance. In addition, EEMs identified during the energy audit are then modeled to determine potential 16 energy savings over existing building operation. The additional costs associated with implementing these EEMs are also considered to determine which audit process provides the best value for reducing energy costs. The research concluded that a detailed energy audit would aid in gathering better data inputs for energy modeling purposes. Such an approach would provide effective EEMs that, in addition to energy cost reduction, can also offset the cost of investing in that extra effort.

Download or read book Investment Grade Energy Audit written by Shirley J. Hansen and published by CRC Press. This book was released on 2020-11-26 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written to give energy-involved professionals the tools they need to take their energy audits to the next level, and use them to accurately predict a building's future energy use and true savings potential. Going beyond the conventional energy audit, which can lead to projections which are frequently off by as much as 20%, this book provides detailed guidelines on how to use the new tool, the investment grade audit (IGA), which enables prediction of savings with much greater accuracy. Building on the traditional audit, the IGA requires the addition of a "risk assessment component" which evaluates conditions in a specific building and/or process and reduces the level of uncertainty as to how proposed energy efficiency measures will really behave over time. The authors have covered every aspect of the IGA, including risk management, the "people" factor, measurement and verification, financing issues, report presentation guidelines, and master planning strategies.

Alanezi and published by . This book was released on 2021 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The building sector has been identified as one of the biggest contributions to electricity and natural gas consumption in the U.S. These findings have necessitated the need for the development of energy saving initiatives in the sector, which will aid in reducing greenhouse gas emission needed to reduce the risk of climate change. However, despite several efforts by state agencies, such as the implementation of Property Assessed Clean Energy (PACE) and On-Bill Repayment or On-Bill Financing of energy efficiency investments, there are significant challenges to achieving energy efficiency in the building sector. Fundamentally the question is "How do we find the most cost effective energy efficiency measures present in the world?" Conventional energy audits, the typical way to discern, struggle from high cost, inconsistency in audit recommendations, and a lack of people trained to deliver. Thus, the approach just is not capable of "at-scale" identification of the measures to address first, then second, and so on. Additionally, it is essential that the savings from any investment and/or even behavioral changes be capable of being measured with accuracy in order to improve the ability to find the most effective energy reduction measures existing in the broader building sector and in order to communicate the relative economic benefits from upgrades to building owners. At this time, unless there are short-interval energy meters in buildings, the ability to measure savings with accuracy is just not there. As a solution, this dissertation investigates utilizing smart Wi-Fi thermostats data to conduct visual energy audits and predict energy savings with improved accuracy from any energy systems upgrade and any behavioral modification. The study leverages data from 101 residences owned by the University of Dayton. In 2015 prior University of Dayton researchers completed energy audits of these; documenting the geometric and energy characteristics and occupancy, as well as documenting any unique energy consuming device such as washers/dyers/dishwashers in the residence. These houses provided a diversity of size, age, insulation, and energy effectiveness. Additionally, historical energy consumption data, as well as smart WiFi thermostat data with corresponding weather data, were collected for these houses. The archived thermostat measured temperature data was used to develop unique power spectrums for the measured interior temperature for each residence. The binned power spectral density is shown to be an effective signature of the energy effectiveness of the various energy characteristics associated with a residence. Moreover, the outdoor temperature for each meter period was binned into histogram groupings.This research utilizes an AutoML H2O package to determine the best machine learning algorithm for predicting both the energy characteristics and energy consumption, as well as complete the tuning needed to determine the best model hyperparameters. Machine learning models were trained to predict attic and wall R-Values, furnace efficiency, and air conditioning seasonal energy efficiency ratio (SEER) using smart WiFi thermostat measured temperature data in the form of a power spectrum, corresponding historical weather and energy consumption data, building geometry characteristics, and occupancy data. The models validation coefficient of performance (R2 values) were respectively 0.9408, 0.9421, 0.9536, and 0.9053 for predicting attic and wall R-Values, furnace efficiency, and AC SEER. This research helped lift up the possibility of conducting low-cost, large-scale, data-based energy auditing of residences that rely only on data that could easily be collected for any residence.Similarly, a power spectrum derived from the measured thermostat indoor temperature is combined with outdoor temperature data and known residential geometrical and energy characteristics in order to train a singular machine learning model capable of predicting energy consumption in any residence. The best model obtained had a percentage mean absolute error (MAE) of 8.6% for predicting monthly gas consumption. This result indicates that the best model is effective to estimate energy savings from upgrades in residential buildings. Specifically, when it is applied to real residences in which attic insulation upgraded, the energy savings estimation uncertainty was less than 7%. This is a significant improvement over the ASHRAE recommended guidelines for estimating building energy consumptions and savings, which has been termed capable, at best, of resolving savings only greater than 10% of total consumption, and, in many cases, unable to resolve any savings at all.

Book excerpt: Energy audits are a powerful tool for uncovering operational and equipment improvements that will save energy, reduce energy costs, and lead to higher performance. Energy audits can be done as a stand-alone effort or as part of a larger analysis across a group of facilities, or across an owner's portfolio. The purpose of an energy audit (sometimes called an 'energy assessment' or 'energy study') is to determine where, when, why and how energy is used in a facility, and to identify opportunities to improve efficiency. Energy auditing services are offered by energy services companies (ESCOs), energy consultants and engineering firms. The energy auditor leads the audit process but works closely with building owners, staff and other key participants throughout to ensure accuracy of data collection and appropriateness of energy efficiency recommendation. The audit typically begins with a review of historical and current utility data and benchmarking of your building's energy use against similar buildings. This sets the stage for an onsite inspection of the physical building. The main outcome of an energy audit is a list of recommended energy efficiency measures (EEMs), their associated energy savings potential, and an assessment of whether EEM installation costs are a good financial investment.

Book Synopsis Development of Next Generation Energy Audit Protocols for the Rapid and Advanced Analysis of Building Energy Use by : Christopher Ahlvin Hartley
Download or read book Development of Next Generation Energy Audit Protocols for the Rapid and Advanced Analysis of Building Energy Use written by Christopher Ahlvin Hartley and published by . This book was released on 2013 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current building energy auditing techniques are outdated and lack targeted, actionable information. These analyses only use one year's worth of monthly electricity and gas bills to define energy conservation and efficiency measures. These limited data sets cannot provide robust, directed energy reduction recommendations. The need is apparent for an overhaul of existing energy audit protocols to utilize all data that is available from the building's utility provider, installed energy management system (EMS), and sub-metering devices. This thesis analyzed the current state-of-the-art in energy audits, generated a next generation energy audit protocol, and conducted both audits types on four case study buildings to find out what additional information can be obtained from additional data sources and increased data gathering resolutions. Energy data from each case study building were collected using a variety of means including utility meters, whole building energy meters, EMS systems, and sub-metering devices. In addition to conducting an energy analysis for each case study building using the current and next generation energy audit protocols, two building energy models were created using the programs eQuest and EnergyPlus. The current and next generation energy audit protocol results were compared to one another upon completion. The results show that using the current audit protocols, only variations in season are apparent. Results from the developed next generation energy audit protocols show that in addition to seasonal variations, building heating, ventilation and air conditioning (HVAC) schedules, occupancy schedules, baseline and peak energy demand levels, and malfunctioning equipment can be found. This new protocol may also be used to quickly generate accurate building models because of the increased resolution that yields scheduling information. The developed next generation energy auditing protocol is scalable and can work for many building types across the United States, and perhaps the world.
