Energy Efficient Design for Buildings with an Industrial Focus
Energy Efficient Industrial Buildings
Emperors I (Caesars Palace Las Vegas)
Chair:
David Yashar, NIST
Saving energy in our home or office comes easy to most of us. But what about when designers are faced with saving energy in food processing plants, factories, or even refineries – facilities where health and safety regulations play a crucial role? This session looks at three such cases of applying energy efficiency measures while maintaining a safe workplace environment. It also explores a new approach to thermal comfort studies in the indoor environment.
1 Performance Assessment of Fanger's PMV in a UK Residential Building in Heating Season (LV-17-C021)
Traditionally there are two approaches to thermal comfort studies in the indoor environment. The first approach is to conduct tests in fully controlled climate chambers located in laboratories which help in maintaining desired environmental conditions for the experiments. The alternate/second approach is to place sensors and collect data in a set of homes and offices over a period of time where researchers have virtually no control on the thermal environment. This paper reports on an original approach that combines the advantages of both these methods. In this research thermal comfort studies were conducted in a test house.
2 Integrating Energy Efficiency Performance in Processes for the Dairy Industry (LV-17-C022)
The dairy industry is one of the most energy intensive sectors in food processing; mainly concentration and spray drying are responsible for high energy consumption. One overall objective is to significantly reduce the energy consumption. Savings are expected to reach over 60%. Amongst others the German Federal Ministry for Economic Affairs and Energy Public Relations publish a subsidy for energy efficient and climate friendly production processes. This program is a good opportunity to the dairy sector in Germany and will lead to increased competitiveness. This presentation focuses on spray dryer plants.
3 An Application of Energy Conservation Measures to a Middle-Sized Factory Using Energy Management System (LV-17-C023)
This paper shows positive results for introducing energy conservation measures after analyzing facility data acquired by Energy Management System in an existing middle-sized factory. The factory produces around 400,000 gas meters a year. It achieved 37% CO2 reduction from 2011 to 2014. Since 2011, some simple measures had been implemented such as switch-off of unused lights and air-conditioners for unoccupied areas. To achieve higher energy conservation, reduction of air-conditioning load with no drop in productivity and workplace quality was critical. To design new effective energy conservation measures it was necessary to analyze room condition data and energy usage data.
4 Energy Efficiency in Buildings Inside Oil Refineries (LV-17-C024)
Buildings located inside oil refineries are a typical example of industrial buildings where designers need to balance life safety and energy efficiency. The three most common hazards that such buildings are subject to are blasts, toxic gasses and flammable gasses. The key to achieving energy efficiency without compromising life safety is to understand the hazards imposed on a certain refinery building and the mitigation measures required. This paper describes how a Vapor Cloud Explosion (VCE) differs from regular explosion and how selecting the right blast damper for the over-pressure and impulse of a specific blast will result in energy savings.

Energy Efficiency Assessment in Industrial Facilities: Case Studies and Lessons
Energy Efficient Industrial Buildings
Augustus V/VI (Caesars Palace Las Vegas)
Chair:
Zheng O`Neill, Ph.D., P.E., The University of Alabama
Technical Committee: 7.5 Smart Building Systems
The U.S. DOE sponsors 24 industrial assessment centers (IAC). These centers conduct energy audit for small and medium-sized manufacturers to identify site-specific opportunities to improve productivity, reduce waste and save energy through immediate changes in manufacturing processes and equipment and energy systems. This seminar covers an overview of IACs and a typical industrial energy efficiency assessment process. Results of data-mining the recommendations made in over 17,000 assessments will be presented. The basic elements of an industrial control system will be discussed with examples of energy efficiency projects. This seminar also covers a framework for achieving energy and material sustainability.
1 Identification and Trends of Most Frequent Savings Opportunities Found and Implemented in Energy Audits of Manufacturing Facilities
The Industrial Assessment Centers have existed for 42 years with an objective of teaching students how to assess energy in manufacturing facilities while providing in-field training by doing assessments. A database exists of the recommendations resulting from these assessments and their consequently implementation. This presentation gives an overview of the IACs and the results of data-mining the recommendations made in over 17,000 assessments. Results are presented for the fraction of total energy costs in gas and electricity use and demand; the most common recommendations grouped by industry NIACS classifications, the most common implemented recommendations; and typical payback periods.
2 Leveraging Control Systems for Energy Savings in Industrial Facilities
This presentation highlights the role of control systems in reducing energy use in industrial facilities. The basic elements of an industrial control system are discussed and examples of energy efficiency projects related to each element are given, accompanied by statistics drawn from reported implemented projects by industry. Some selected industrial case studies reaffirm the growing potential of control systems to improve product quality, while reducing energy usage and production costs.
3 A Guide to Environmentally Sustainable Manufacturing
This seminar presents a framework for achieving energy and material sustainability. It describes a methodology to calculate the necessary rates of improvement to achieve net-zero carbon and net-zero waste manufacturing. The speaker describes methodologies to achieve energy and material sustainability based principles of energy and material efficiency applied across to energy systems and material flows. The presentation shows how the savings from energy and material efficiency can find the transition to and maintenance of sustainable manufacturing.

What Do We Know About Energy Use in Agriculture Facilities
Energy Efficient Industrial Buildings
Emperors I (Caesars Palace Las Vegas)
Chair:
Carol A. Donovan, Alares LLC
Technical Committee: 2.2 Plant and Animal Environment
This session highlights the energy use data available and describe what assumptions are used in interpreting the available information. It provides a perspective on the portion of agricultural energy used for the operation of agricultural facilities and particularly what mechanized systems in these facilities are major energy users. The session also demonstrates what information is still needed to effectively evaluate energy use in facilities with building envelopes.
1 What Do We Know about Energy Use in Agricultural Buildings
Energy use in agricultural facilities is only one sector of the total energy used in the agriculture industry. The challenge is to correctly determine energy consumption for these facilities. The United States Department of Agriculture (USDA) provides many reports of energy used in agriculture, however reporting is always provided in monetary values. Using these values, actual energy use can be approximated for different sectors of agriculture and different energy sources. Overall, fertilizer production and diesel fuel are the dominant energy inputs on farms. Electricity use is a major player as well, and the predominant energy form used in agricultural facilities.
2 Energy Use in Livestock Production Facility Systems
The predominant energy forms used in livestock facility systems include electricity and liquid propane (LP gas). Using the approximated energy use from USDA data and other sources, electricity and LP gas use will be partitioned into different use categories for swine, dairy and poultry facility systems. LP gas typically is used for space heating and water heating. Electricity is typically used for ventilation, air circulation, lighting, equipment motors and on-farm refrigeration. With an understanding of the partitioned energy use within a given livestock sector, the implementation of energy efficiency practices and standards can be evaluated.
3 Energy Use in Indoor Plant Production Facilities
Energy used for growing plants indoors ranges from very small to very large, facility type, and crop. Indoor crop production is inherently more energy use intensive than outdoor cultivation due to the use of systems to control the growing environment. Systems used in vertical farms, plant factories, and cannabis facilities are much more energy intensive, requiring supplemental lighting for 12 or more hours, large air conditioning units to remove both sensible and latent heat, and large fans to achieve high air exchange rates. Understanding energy use in indoor plant production will allow the identification and implementation of energy efficiency measures.
