The North Texas IBPSA Chapter hosted an October meetup to discuss the new changes to the standard and how it impacts the energy modeling process.
The 2016 update of ASHRAE Standard 90.1 Energy Standard for Buildings is a major revision, containing more than 125 changes from the 2013 version. Together, Standards 90.1-2007, 90.1-2010, 90.1-2013 and 90.1-2016 produce almost 40% energy savings from the 2004 version. This slide deck is not comprehensive, but an overview of the Appendix G methodology.

Commercial Building Codes: Finding the Path to Improved ComplianceZondits
Electric tumble clothes dryers were introduced in the United States in the late 1930s, and until
recently have remained largely unchanged, with only small incremental improvements in operation.
Recent advancements in electric clothes dryers range from automatic control improvements to alternative
methods for removing moisture, with heat pump technology showing the most promise for efficiency
gains. The paper will introduce the reader to advanced dryer technologies, including improved moisture
sensing controls, non-venting moisture removal/condensation, and heat pump drying. Results of both field
and laboratory testing of these features will be presented.
In order to calculate energy savings associated with these new advancements, baseline values must
be established. The results of several recently completed field studies, conducted in the Northeast and the
Pacific Northwest, are presented. The field study results demonstrate that dryer usage and potential
savings are higher than the assumptions utilized by the ENERGY STAR program. Load shapes generated
from those studies show regional variation in usage patterns. Finally, the authors describe the Super
Efficient Dryer Initiative (SEDI) and its stakeholder contributions to the various activities, including DOE
and EPA initiatives, which are helping to build the market for efficient dryers.

Monday, November 30th Track 1 Session 3
This session will focus on the impact U.S. EPA Clean Power Plan (CPP) will play in shaping changes to the natural gas market, including the shale gas marketplace both domestically and perhaps internationally. The inter-dependency between the natural gas and electric industry is growing as there is more movement toward natural gas fired generation and away from coal fired generation. Natural gas companies are already seeing an increased need for infrastructure expansion from the growing gas-electric inter-dependency. What are the benefits and risks facing the natural gas industry? What role does the shale gas industry play? What will the changes mean for gas producers, electric utilities and technology now and in the future both in the U.S and abroad?

Using Data Analytics to Bridge the Gap between M&V 1.0 and 2.0Zondits

AESP 2017 National Conference: Session 5B: Evaluation
Summary: Successful implementation of energy efficiency as a grid resource requires defense that installed measures confidently provide capacity relief during the network peak. Measurement and verification (M&V), often the means of defending these programs, is at a crossroads, with the debate intensifying between traditional M&V approaches and the meter-based approach championed by “M&V 2.0.” Traditional M&V is the gold standard for high-certainty results required by jurisdictional evaluations, but it can be relatively cost- and time-intensive, due to the numerous on-site inspections, metering, and analyses required for each new initiative. As a result, the industry has looked to M&V 2.0 as an alternative, with real-time, building-level data from advanced metering infrastructure (AMI) reducing project costs and timelines while providing robust data to assess hourly operation by account. However, the “black box” methodology of characterizing measure-level operations from building-level data leaves many skeptical of the ability of M&V 2.0 to support energy efficiency as a resource as accurately and defensibly as traditional M&V. This paper presents the lessons learned from a recent project utilizing a granular M&V methodology that borrows successful aspects of both traditional and 2.0 approaches, maximizing accuracy and minimizing costs by using predictive analytics on previously collected end-use metered data. While no M&V approach can ever be one-size-fits-all, this hybrid model shows that the best M&V solution is often a tailored combination of both approaches.
Presented at the AESP 26th National Conference
The growing focus on distributed generation (DG) has fueled new approaches that streamline and reduce the complexity of project installations. This paper presents the design and initial results from an accelerator program that encourages and promotes the installation of combined heat and power (CHP) systems in the mid-range market. The program includes a combination of pre-approved system configurations in a catalog of options, approved vendors, as well as outreach support to drive program participation and provide technical and application assistance to vendors and customers. The program also includes a market characterization effort to aid the outreach team and vendors in targeting participants.
Demand response programs across the country have many large facilities considering the deployment of energy storage technologies. Technologies developed for facility- and campus-scale energy storage show promise for managing short-term demand peaks as well as longer-period demand response events.
The presenter has investigated facility/campus-scale energy storage for efficiency program administrators in the US and recently completed a storage technology research report for an international consortium of utilities. This work has identified promising avenues for distributed storage. Currently, facility-scale storage has three primary uses: 1. power quality – the monitoring and regulation of voltage fluctuations, frequency disruptions, and harmonic distortions, 2. bridging power – short-term power supply for critical demands, often used to cover time periods in which emergency generators are powering up, 3. energy management – energy storage on a scale to support a facility/campus for extended periods of time. These systems can be responsive to utility demand programs and time-of-use rates to cut peak demand costs.
This presentation will include the technical properties of current storage systems, including flywheel, compressed air, and various battery technologies. The technical and market barriers associated with distributed storage, along with proposed paths for resolving said barriers, will also be discussed.
Given the uncertainties surrounding energy prices and pending environmental regulations, there is a growing need for industrial facilities to address energy usage, greenhouse gas emissions, sustainability, and process efficiency in their planning. Operations teams and management staff often fail to adopt long-term strategic energy master plans because of resource constraints and the need to focus efforts on near-term capital improvement projects and maintenance. This can result in higher-than-necessary energy costs, unanticipated compliance issues, and lower profits. This presentation will explore a tailored, strategic energy master-planning process that will guide manufacturers in making informed decisions about their facilities’ infrastructure, energy management practices (such as ISO 50001 and SEM), sustainability goals, and process energy efficiency improvements (energy per unit of production).
The first step is a visioning process with decision-makers to identify the desired outcomes, define the constraints, and create an information exchange culminating in a work plan that defines the development of the energy master plan. Next, a process of benchmarking, measurement and verification (M&V), assessment, analysis, financial deliberation, optioning, prioritization, and scenario analysis is developed. This results in an actionable master plan that manufacturers can implement over multiple years.
Maintaining and Growing Efficiency Efforts in the Changing C&I LandscapeZondits
Large industrial and commercial customers use significant amounts of energy and any strategy to
improve energy efficiency is deficient without them. Still, they have not fit easily into utility energy
efficiency programs with endemic issues of rate impacts, net-to-gross, etc. Further, recent effects
technological change on the electrical grid against the backdrop of slow industrial recovery may have
affected the support of utilities for improving these customers’ efficiency. The panelists will consider
recent initiatives in the upper Midwest, New York, and elsewhere concerning the complex role large
customer play in energy policies and programs.
