Taking Stock – 40 years of Industrial Energy AuditsLeonardo ENERGY
Industrial energy audits were amongst the first energy efficiency policy measures developed in response to the oil shocks of the 1970s. Since then they have become enormously popular in industrialised economies. In the EU they are mandatory for large organisations under the EU Energy Efficiency Directive. Developing countries are considering them as they scale up their own climate programmes.
So interest in audits can only grow. But, from a policy-maker’s perspective, do they work? How do they work? How could they work for me? Certainly, in principle, audits are extremely important because they get to the heart of how a company uses energy. But after 40 years, the scientific literature on audits is large and complex and difficult for the non-specialist policy-maker to wade though.
This webinar tell the story of audits in a way designed to cut through this complexity. It recounts the history of audits and sets out why they are important. It sets out some of the main features of successful audit programmes, and, from the practical experience of the speaker, how to go about putting one together. It then considers the main problems with audits and how these can be addressed. Finally the talk will look ahead to see how audits might evolve in the near future.

The document summarizes a field study of 8 cold-climate air-source heat pumps (ccASHPs) installed in Minnesota homes. It found that the ccASHPs performed as expected for heating, with annual COPs lower than ratings due to auxiliary heat use. Flex fuel ccASHPs could heat below 5°F while all-electric systems could heat below -13°F. Installations of ccASHPs showed potential for 40-60% reductions in site energy use, emissions and costs compared to propane or electric resistance heating. The study demonstrated ccASHPs can provide beneficial electrification in Minnesota.
This document summarizes research on cold-climate air-source heat pumps conducted in Minnesota homes. Eight heat pumps were monitored, including six ducted whole-home systems and two ductless mini-split systems. The heat pumps performed well down to 5-10 degrees Fahrenheit for ducted systems and below -13F for ductless. Annual COPs were 1.2-2.1, providing energy savings of 40-60% compared to electric resistance or propane heating. Paybacks were estimated at 6 years or less when paired with replacing an existing heating or cooling system. Further research is needed to optimize controls and expand applications to multifamily buildings.

The Center for Energy and Environment (CEE) provided information to the House Energy and Climate Finance and Policy Committee. CEE takes a data-driven, community-based, and consumer-focused approach to reducing energy waste through programs, services, policy work, and technical research. CEE has award-winning efficiency programs across Minnesota that have saved customers over $7.3 million annually in one representative's district. CEE advocates for legislative initiatives that integrate efficient fuel switching, demand response, and a clean energy first approach into Minnesota's conservation programs.
The document discusses achieving a healthy low-carbon economy in Minnesota. It identifies three keys: maximizing energy efficiency, decarbonizing electricity supply by retiring coal and other high-carbon plants, and strategic electrification of parts of the economy like transportation and buildings. Maximizing efficiency can save significant amounts of energy and avoid infrastructure costs. Decarbonizing electricity supply is critical as over 95% of the state's power sector emissions come from plants that will retire in the next 20 years. Strategic electrification technologies like heat pumps, electric vehicles, and buses can reduce emissions if deployed in a way that reduces energy use and costs and does not excessively increase peak demand.
This document summarizes a field study of 8 cold-climate air-source heat pumps (ccASHPs) installed in Minnesota homes. 6 units were ducted whole-home systems while 2 were ductless mini-splits. Instrumentation monitored performance of the heat pumps and backup systems. Results found ducted units could provide heat down to 5-10°F while ductless units operated below -13°F. Ducted flexible fuel ccASHPs improved annual COP to 1.3 and reduced propane use by 60% compared to condensing furnaces. Ductless ccASHPs achieved annual COPs of 2.1, reducing energy and costs by 55% versus electric resistance heat. The study concluded
This document summarizes research on the cost effectiveness of condensing boilers. Field research was conducted on existing condensing boilers, which found average efficiencies of 90%. Retrocommissioning actions like lowering supply temperatures and adjusting reset curves improved efficiencies by 1-3%. On average, condensing boilers provided 13% annual savings over standard boilers. The average price difference of $2,300 between condensing and standard boilers means condensing boilers have a simple 25-year payback and are cost effective over the lifetime of the unit, with a path to a 10-year payback.
This document summarizes the results of a pilot program that provided commercial energy code compliance services through plan review and design team support. The program worked with cities and design teams on several commercial building projects. It found that targeted tools and building-specific assistance helped capture energy savings cost-effectively. Providing support to city reviewers also had more success recruiting participants with lower marketing costs. Overall, the pilot demonstrated significant potential for energy savings through improved commercial building energy code compliance.
Here are some key considerations for utility EV charging programs based on the discussion:
- A single network provider can simplify program administration and enable integrated demand response capabilities across different charging locations and hardware options. However, it may limit customer choice.
- Make-ready incentives and rebates with multiple qualified network providers gives more customer choice but makes demand response coordination challenging if networks are not interoperable.
- Utility ownership of charging infrastructure allows more direct control over demand response but may require larger upfront investment compared to make-ready incentives.
- Analyzing customized charging data from a single network can provide valuable insights for utilities to better understand customer needs and charging behaviors.
This document summarizes the results of a field study evaluating the performance of transport membrane humidifiers (TMHs) retrofitted to standard efficiency furnaces. The study found that TMHs increased furnace efficiency by 9% for space heating and humidification by adding over 10,500 BTUs per hour. TMHs also improved indoor humidity levels during cold weather without risk of over-humidification. Total installed costs for TMHs were estimated between $1,400-$1,900 with payback periods of 3.9-17.3 years depending on location and energy savings from both heating and humidification. The document concludes that TMHs are a cost-effective alternative to upgrading older furnaces but challenges remain in commercializing the
This document summarizes research on automated house sealing using aerosolized sealants. Key points:
- Air sealing homes can reduce energy use by 30% by reducing air leakage. Aerosol sealing provides an effective way to thoroughly seal homes.
- Field tests with builders showed aerosol sealing reliably achieved tightness standards, reducing leakage by 54-95% in new construction and 39-88% in existing homes.
- Two sealing options were evaluated: sealing after or before insulation. Both reduced leakage by 70-75% but sealing before insulation allowed sealing of more areas.
- The research aims to integrate aerosol sealing into standard construction practices to lower costs and improve performance of home tight
This webinar summarized a research project that evaluated the effectiveness of demand control recirculation systems in commercial hot water applications. Demand control systems use sensors and controls to reduce hot water recirculation pump runtime when hot water is not being used. The project monitored 6 sites before and after installing demand control systems. On average, the systems reduced thermal energy use by 14-18% and pump electricity use by 70-96%, saving $125-1356 per year depending on the site. The simple payback for the control systems was 1-2 years for larger sites and 10-20 years for smaller sites.
This webinar discussed research into optimizing the operation of indoor public pool facilities in Minnesota to save energy. The research characterized over 2,000 indoor pools statewide, conducted in-depth evaluations at 6 sites, and identified key savings opportunities. Statewide, HVAC control upgrades had the largest potential savings. Operational improvements like adjusting temperature and humidity setpoints and installing pool covers could also significantly reduce energy use. The webinar provided recommendations for utility programs and introduced guides developed for pool operators and recommissioning providers.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

13. Pg. 13
Findings – Enhanced Inspection
• Inspectors not interested in ‘going down the rabbit hole’
of an enhanced energy assessment
• Realize the detail and complexity of energy recommendations
• Buyer inspection already 4 hours long
• Not interested in adding ‘extensive’ data collection
• 1 company completed enhanced inspections
• Saw this as a potential market differentiator
14. Pg. 14
Findings – Training and Time
Inspection Type Basic Inspection Enhanced Inspection
Training • Already familiar with
data points
• Need to cover data
collection
• Blower door demonstration
and on-site training needed
• On-call help
Time and Effort • Fit into current
process
• Little to no extra time
needed
• Additional 30 – 60 minutes
• $50 not enough
compensation to motivate
15. Pg. 15
Energy Report - Key considerations
• Cost-effective recommendations
• 10 year payback or less
• Prioritize recommendations
• Access Issues – wall and attic spaces
• Report expected levels based on home age
• i.e. “Homes built prior to 1945 typically have little insulation…”
• Advisor Service – need help with next steps
• People have little experience with recommended projects
16. Third party consultant administered post pilot
• Inspectors are a trusted expert – homebuyers look to them for
advice.
• Homebuyers are an engaged audience – Inspectors
described them as ‘blank canvas’ ready to have details of
their home fill that space
• Inspectors are ok with touching on energy, but like to stay
within their scope and refer homeowners from there.

Homeowner Phone Survey
18. Pg. 18
Conclusions
• Basic inspection fits well within inspection process
• Both TISH and voluntary buyers inspections
• Minimal training
• Similar data collection
• Valuable report - intro to energy efficiency
• Asset rating – informs market
• Primer for energy projects and next steps
19. Pg. 19
Conclusions
• Paperwork and process was cumbersome
• Online data entry and reporting needed for scale
• Enhanced inspection a bigger lift
• More training, higher cost, lack of motivation
• Ideal time to inform market
• Motivated and engaged audience
• Info from trusted source
• Importance of utilizing existing city processes
• Increase compliance
• Saves resources
20. Incorporate energy disclosure into TISH
• Policy change is needed –
• Minneapolis is interested
• Need to work with each city individually
• Fits within many City’s climate goals
• Add data points needed to generate an asset rating
• Create an energy disclosure report – separate from TISH
Future Work
23. Large Scale Pilot
• Test effectiveness as utility program strategy
• Customer engagement – motivated audience
• Inspector recruitment
• Leverage this resource/market
• 51,622 inspections in twin cities metro
• Test cost effectiveness
• Cost of inspector data collection and recruitment
• Track utility savings from inspection visits
Future Work
Add ACEEE anecdotes here –
1) A short anecdote about your experience(s) at ACEEE (i.e.; how many times; first time; first impression; a funny thing happened, etc.) or What is it about our energy efficiency industry or your current job that you most appreciate?
2) What lead you to the topic you are about to present; why do you think it would benefit the audience/industry?
Start with diagram
Time of sale
Informing the market; eventually influence
Mention Minneapolis and CPE interest
70% need either attic or wall insulation
The pilot informed potential changes to the TISH process, including how to better collect and report on energy-related information, as well as how to provide energy data and reporting during voluntary buyer inspections.
Used buyer so the buyer would get energy report…
Still evaluated how this would work within TISH
Small scale…a little slow and cumbersome? Or mention in conclusion?
Tested two inspection types…focused on energy assets…use the most energy
Basic – simple but able to generate needed report info…mention windows
Enhanced – closer to an energy audit
Note – inspections can’t be intrusive-no drilling holes
1 page report
Mention no utility bill data – Wanted to focus on assets and next steps…
bill data can be helpful aide, but doesn’t outline what needs to be done/improved.
Often skewed by behavior and residents as well.
Didn’t fit scope of pilot.
Similar areas they are already inspecting
No incentive budget
Homeowner interest, willing to pay
Found basic info helpful
Easy implementation – informs market of largest EE assets
