Best Practices for Lighting Audits

October 9 and 10, 2018

(Previous September 26, 2018)

James Donson,  L.C., P.E.
Project Manager

Before embarking on any lighting modifications or an upgrade, it is critical to conduct a comprehensive lighting audit. Energy service companies, architects, lighting designers, and engineering firms can conduct lighting audits. They can also be done by qualified internal staff or maintenance engineers.

2-Day Class Description

This new 2-day, updated and expanded interactive class will cover how to conduct a preliminary energy audit of lighting usage, including outdoor spaces. Hands-on exercises will include documenting the number and type of fixtures in use, their light sources (and lamp type/model/wattage), the light levels in various areas, how long the fixtures are on per day (and variations during weekends), and what controls are in use.

Participants will also learn to note the placement and light distribution of fixtures and suggest changes if needed. The class will also demonstrate how an audit also helps to identify the types and quantity of devices not connected to any control systems, and how to determine whether they should be. Participants will also learn how to use the results from the audit to assess the savings potential of various efficiency measures so that they can be properly considered before implementation.

Understanding and Applying the M&V Concepts and Options of IPMVP

October 9, 2018

David Jump, PhD, P.E.
Director

Measuring energy savings has become an expected skill for a wide range of building professionals, from energy consultants to stationary engineers. This full-day training will explore the International Performance Measurement and Verification Protocol (IPMVP), which is the gold standard for M&V procedures in the energy efficiency industry.

The course will provide an overview of M&V, define key terms, and review its key concepts. It will present and discuss M&V Options A, B, C, and D as defined in IPMVP, and review example savings calculations for each option.

  • Option A: Retrofit Isolation Approach: Baseline and post-installation energy use are estimated using an engineering analysis of measurements of the most critical parameter.
  • Option B: Retrofit Isolation or System-Level Approach: Baseline and post-installation energy uses are estimated by measuring all relevant parameters.
  • Option C: Whole-Building Verification: When several systems have been retrofitted, verification methods determine savings by studying overall energy use in a facility.
  • Option D: Whole-Building or Component-Level Verification: Calibrated computer simulation models of component or whole-building energy consumption determine energy savings.

The training will also include in-class exercises where the class participants will apply the different M&V options by calculating energy savings for a variety of project scenarios. This training will be taught by David Jump of kW Engineering. David is a long-standing member of the IPMVP Committee and a major contributor to this protocol.

He presents a cost-effective approach to EBCx and developing a prioritized migration strategy for controls upgrade, using analytics to serve as a framework that Owners and facility managers can use to justify a controls modernization project. Using analytics on the onset of any controls modernization project enables control system migrations to happen at the Owner’s pace, allowing new controllers to be strategically integrated with existing equipment. This allows organizations to develop migration strategies and prioritize controls upgrades without having to “rip and replace” their entire hardware and software systems.

Forging a New Era in Lab Benchmarking

October 15, 2018

Alison Farmer, PhD
Director

Things are changing in the world of lab benchmarking. New studies are paving the way for fairer, more useful approaches to assessing lab building performance, and the 16-year-old Labs21 Benchmarking Tool is finally being retired. I2SL and LBNL are working together to create a new, improved, modern lab benchmarking tool to better serve the lab community. The new tool is due to be released in early 2019. By the time of the conference, the team will have completed a draft design of the new user experience and benchmarking database. In this special session, we’ll offer a sneak preview of the new tool, we’ll explain the reasoning behind the new features, and we’ll hold a mini design charrette for attendees to provide feedback to make sure our industry’s needs are met.

The Standard for Energy Audit Levels 1, 2 and 3 is Changing - News You can Use

October 17, 2018

Jim Kelsey, P.E.
President

The business of performing energy audits has long lacked any regulation or standardization of approaches. What makes an energy audit acceptable, good, or great has been the subject of much discussion and debate. And what are considered best practices in the field has been akin to an oral tradition, where practitioners in the field pass knowledge and approaches from person to person.

Jim shares the results of the development of the first true industry standard, describes some of the contentious issues encountered, and summarizes what the energy auditing community agreed upon for the requirements of Level 1, 2 and 3 energy audits outlined in Standard 211.

Integration of HVAC and lighting control systems

October 24, 2018

Lyn Gomes, P.E., CCP, LEED AP, CLCATT
Project Manager

Significant energy savings can be achieved by turning off HVAC when spaces are unoccupied. In the past, carbon dioxide was used as a proxy for occupancy, but energy savings only made sense for high occupancy spaces with transient use (e.g. conference rooms). With the ubiquity of lighting controls, facilitated by Title 24-2013, turning off HVAC systems with a signal from the occupancy sensor is becoming the trendy way to save energy in advanced buildings. But just because you can use them doesn’t mean it’s the right thing to do. Inadequate detailing and specifications, poor coordination between trades, and a siloed maintenance team are but some of the torpedoes that will sink the grand vision of an integrated system.

Lyn will share views on the advantages and disadvantages – including huge implications for maintenance – of four different ways to implement occupancy based ventilation on your projects. This presentation includes examples of the challenges and complexities encountered when designing and building integrated systems. Solutions based on real-world experience in implementing advanced lighting controls projects and integrating them into HVAC control systems will also be included.

Best Practices for Lighting Retrofits

November 6, 2018

James Donson,  L.C., P.E.
Project Manager

Historically, energy efficiency incentives for lighting products have focused on incremental technology improvements using lamps and ballasts; however, evaluating retrofit projects through the lens of incremental component upgrades may ignore further opportunities for improvements. These opportunities extend beyond lamps and ballasts to include luminaires, advanced lighting controls systems, design expertise, reflectances, space geometry, and workplace design as well as consideration of project location, building orientation, and available daylight. This comprehensive approach to evaluating all of the energy efficiency tactics while also delivering lighting quality in keeping with the Illuminating Engineering Society (IESNA) standards is the basis of this Best Practices for Lighting Retrofits class. The information presented will be relevant to existing buildings as well as new construction and solutions presented will go beyond simple component retrofit solutions to include solutions with new fixtures and controls for deeper energy savings. Many of the professionals that are responsible for lighting do not practice solely as lighting experts, therefore, this class will offer energy efficient lighting approaches and useful templates for typical spaces and conditions. This class is intended to serve as a starting point for those professionals who otherwise may not consider options such as using new fixtures and controls. This class will be beneficial for owners and tenants considering lighting improvements, architects, engineers, lighting suppliers, lighting manufacturers, electrical contractors, electrical distributors, and energy program managers.

A Class for Control Freaks: Getting the Most from your Building Automation System

September 9, 2018

Arik Cohen, P.E.
Principal

New Offering!!! Statewide energy savings goals are depending more and more on the optimization of our existing buildings through low-cost measures. Many of these projects originate from the control systems we use to manage the operation of our HVAC and lighting equipment.  This class will explore common control strategies including schedules, setbacks, resets, lockouts, vacancy controllers, demand control ventilation, CO controllers, economizer operation, and the control of variable speed equipment. We will also look at strategies for diagnosing improper operation of Building Automation Systems using graphics from these systems, trend data and data from loggers. We will emphasize the control strategies required in Title 24 and include material on how to approach specific control strategies as part of retro-commissioning projects.

MBCx Detective: Finding Evidence-Based Savings with Analytics

October 18, 2017

Lincoln Harmer, P.E.
Senior Engineer, kW Engineering

Lincoln presents ways that analytics can bring legacy control systems into the future. The performance of a building is highly influenced by the quality of the controls infrastructure being utilized. Naturally, older systems still relying on legacy control systems are more prone to performance degradation than those with more modern controls. Typically, this is because the root causes of system faults are not fully resolved due to the rising cost of supporting older generations of system components and the inability for multiple vendors to exist on the same system. However, while maintenance costs may be rising, with spare parts becoming scarce and expensive, true maintenance savings alone is usually not enough to justify the capital investment involved with upgrading an entire control system.

He presents a cost-effective approach to EBCx and developing a prioritized migration strategy for controls upgrade, using analytics to serve as a framework that Owners and facility managers can use to justify a controls modernization project. Using analytics on the onset of any controls modernization project enables control system migrations to happen at the Owner’s pace, allowing new controllers to be strategically integrated with existing equipment. This allows organizations to develop migration strategies and prioritize controls upgrades without having to “rip and replace” their entire hardware and software systems.

Smart Benchmarking for Lab Buildings

October 18, 2017

Alison Farmer, PhD
Project Manager

Benchmarking against other buildings is the first step in any efficiency program. It tells us where we stand, provides a baseline against which to gauge progress, helps us prioritize attention and identify opportunities, and is an excellent catalyst for the conversations that drive improvement. This session demonstrates the smart ways to use lab benchmarking data and introduces the new lab benchmarking portal being developed at I2SL as part of the DOE Lab Accelerator Program.

Arik Cohen, P.E.
Prinicpal

This interactive presentation (and play on the popular CSI TV franchise) works directly with the audience to approach existing building commissioning (EBCx) from a forensics perspective. Using photographs, screen captures from control systems, trend data and other investigative tools, the panelists for this session reveal crimes of energy waste and dysfunctional operation. For each situation the speakers provide the data used to identify the issue, and then ask the audience “solve the case”. The session begins with an introduction to the building forensic tools available to commissioning providers, including site observation, building performance data, control system graphics, and functional test results. The presenters also provide notes on best practices for each of the forensic tools listed.

Don't Let This Happen To Your Building: Preventing and Solving System-Wide Problems in Central Plants

October 17, 2017

Sanjiv “Sunny” Devnani, P.E.
Project Manager

In the not too distant past, new building commissioning concentrated at individual equipment, with less focus on the systems as a whole (i.e. whole building commissioning – remember last year’s conference?). Existing Building and Retro-commissioning look at building performance in order to understand how to make the building operate well and save energy in the future.

In the present, design engineers are trying to use advanced control sequences, but are still looking at the individual equipment. Facilities engineers, pressed to their breaking point, are applying overrides – sometimes reactive, other times proactive – to achieve thermal comfort for the building occupants. The result of these overrides can help or hurt the operation.

Commissioning providers can work together with design and facilities engineers to prevent and solve system-wide problems in central plants. Doing so will lead to happier occupants, less work for the facilities engineer, less wear and tear on equipment, and in some cases even generate enough savings to pay for a new control system! Come to this presentation to find out why, when it comes to central plants, commissioning providers must think in terms of systems. Also learn about how overrides can be a double-edged sword by either removing an unnecessary, energy intensive operating condition or sending the central plant into a death spiral.

Playing Nice: HVAC and Lighting Controls Integration

October 17, 2017

Lyn Gomes, P.E., CCP, LEED AP, CLCATT
Project Manager

Occupancy based demand control ventilation is becoming the way to save energy in advanced buildings. In the past, carbon dioxide was used as a proxy for occupancy and driver for ventilation, but with the ubiquity of lighting controls, especially with recent code mandates, occupancy sensors are being used more and more.

But just because you can use them doesn’t mean it’s the right thing to do. This joint discussion between Gomes, a commissioning provider, and Lewis, a representative of the UC Davis Facilities Management Energy Conservation Office, includes examples of the challenges and complexities encountered and solutions based on their real-world experience implementing advanced lighting controls projects and integrating them into their HVAC control systems.

The speakers will share views on the advantages and disadvantages – including huge implications for maintenance – of different ways to implement occupancy based ventilation on your projects. They will cover:

  • Four methods for implementing occupancy-based ventilation
  • Things to watch out for in the control sequences
  • What to remember for integration
  • How to prevent a maintenance nightmare
  • How choice of occupancy sensor manufacturer affects implementation

Food for Thought: Ingredients for a Delicious Meter-Based Restaurant Program

August 30, 2017

Amy Allen, P.E.
Project Engineer

A meter-based M&V approach can aid utilities in meeting increased targets for energy savings, and quantifying savings more rigorously. In 2015, California adopted legislation (Senate Bill 350 and Assembly Bill 802), to pursue deep, reliable, and lasting energy savings by authorizing efficiency program administrators to quantify gross energy savings using a normalized metered energy consumption (NMEC) approach, with an existing conditions baseline. While this approach aligns the accounting of energy savings with a customer’s expectations, it is not without risk. Learn the technical risks associated with the applicability and accuracy of the meter-based savings methodology, and how it informs program designs to assure program success. In response to the legislation, a major Southern California gas program administrator is developing a program that targets gas, electricity, and water resources for commercial restaurants in its service territory. The program proposes to quantify normalized savings using a NMEC methodology, which requires modelling of energy use with weather and other independent variables. Key questions concerning the applicability of models to restaurants arise: can the restaurant’s energy use patterns be modeled, and are the modeling algorithms appropriate for the restaurants?

Amy presented the results of an in-depth analysis of natural gas energy use in restaurants that have participated in recent past energy efficiency programs. We collected baseline and post-installation monthly gas data for over 400 restaurants, applied a set of piecewise linear regression models, and determined the accuracy of each model for the population.

M&V 2.0: New Developments and Applications

September 12, 2017

David Jump, PhD, P.E.
Project Manager, kW Engineering

As our energy management practices turn toward deep energy savings projects, continuous energy management programs, and sustainability practices, there is more interest in and use of data from advanced metering systems. The short time interval data from these systems provides rapid feedback on a building’s or system’s energy performance, and advanced analytic methods enable more accurate accounting of savings. However the industry is realizing that the analytic methods are more complex and less understood and may act as barriers to their application by most stakeholders. This presentation will clarify the process and requirements in applying “M&V 2.0” to a project, discuss common issues, identify useful tools, and demonstrate its benefits in case studies.

Turning on the Switch to Lighting Controls in High Performance Buildings

August 30, 2017

Lyn Gomes, P.E., CCP, LEED AP, CLCATT
Project Manager

Lighting control systems operate in a highly proprietary environment, making interoperability impossible between manufacturers and stymying “or equal” substitutions. Little can be done to remedy poor design or application of lighting controls, so design must involve an integrated, preventive approach across all building systems. A knowledgeable commissioning provider can coordinate this effort. Learn how the commissioning process bolsters and supports successful lighting control system design, installation, and operation.
