About the Rankings

The Los Angeles Business Journal annually ranks the top privately held companies headquartered in the greater Los Angeles area based on percentage revenue growth.  The LABJ released the final rankings at their 22nd annual Fastest Growing Private Company awards held on November 7th at The Reserve in downtown Los Angeles.


The Federal Housing Finance Administration (FHFA) just released new requirements for the 2019 Fannie Mae and Freddie Mac Green Lending Programs. The new requirements may increase the implementation cost of these loans for some borrowers. However, with careful consideration of the type and quantity of energy-saving and water-saving measures implemented, this cost can be minimized.

Partner Energy believes that even with these new requirements, the interest savings offered by Green Loans means they are still a favorable financing choice for most clients.


The 2018 FHFA requirements state that borrowers must achieve EITHER a 25% reduction in energy consumption OR a 25% reduction in water consumption. Most borrowers met this requirement in the most cost-effective way by implementing only water-saving measures – typically upgrading shower heads, faucets, toilets and at times, improving irrigation systems or landscaping.


The 2019 FHFA requirements state that borrowers must achieve an overall 30% reduction in energy AND water consumption with a minimum of 15% this reduction coming from energy consumption. Obviously, this means that both energy-savings measures and water-savings measures will need to be implemented to meet lending requirements. Furthermore,  FHFA requires that the borrower engage a third party to help collect and process utility data for use in energy star portfolio manager prior to loan close.


The old requirements favored the implementation of water-savings measures alone to meet the 25% consumption reduction requirement. The typical cost of implementation was approximately $300-$500 per unit. A significant amount of that cost usually came from replacing a toilet and the remaining from upgrading shower heads and faucets. Since the new requirements require that at least 15% energy savings is achieved, we anticipate that most borrowers will shift away from toilet replacement ($200-$400 unit) and use those cost-savings to make interior and exterior lighting upgrades (which tend to be the most cost-effective and high-impact energy-saving measure to implement).  While lighting upgrades may be slightly more expensive than toilet upgrades, in the $250-$500/unit range, this increase will be mitigated somewhat by the cost savings of not replacing existing toilets. If it is impossible to achieve a 15% energy savings by only upgrading interior and exterior lighting, borrowers will need to consider other energy-savings measures such as replacing appliances, hot-water heaters, or HVAC systems. Since energy and water savings measures do not have to be implemented in every unit, your energy consultant can advise you on the quantity of units that need to be upgraded to meet the minimum requirements.


Partner Energy believes that for most borrowers, FHA Green Loans are still a favorable financing opportunity despite the more stringent requirements now in place. That being said, it is more important than ever that borrowers consult with their energy consultant to determine the most cost-effective ways to meet the new requirements for FHA loans given each property’s condition and upgrade budget.

New York City Local Law 87

Energy Audits and Retro-Commissioning for Building Owners and Managers

As part of New York City’s Greener, Greater Buildings Plan (GGBP), Local Law 87 (LL87) mandates Energy Audits and Retro-Commissioning every ten years for all buildings over 50,000 square feet. LL87 provides building owners and managers insight into energy consumption and building performance with the goal of improving sustainability and decreasing energy waste.


Step 1: Energy Audit

A Partner Energy engineer will collect building energy data and catalog baseline HVAC systems, lighting and envelope conditions. The auditor will then identify capital improvements and/or system replacements that will save energy, along with measure-specific installation costs and energy cost savings. Typical measures include:

  • Lighting upgrade (e.g. fluorescent to LED)
  • Boiler replacement
  • Roof insulation


Step 2: Retro-Commissioning

A Partner Energy retro-commissioning agent will identify opportunities for tuning and repairing infrastructure that affect the building energy use. The City prescribes Retro-commissioning focus areas, which generally consist of low-cost measures such as:

  • Optimizing HVAC controls
  • Testing, sealing, and balancing ventilation systems
  • Ensuring or installing adequate pipe insulation

Building owners must implement corrections identified in the Retro-Commissioning study. These low cost modifications often result in significant savings with quick paybacks. Partner Energy has extensive experience working with property management staff to implement fixes, which improves performance and extends the useful life of existing systems.

The Energy Audit report identifies significant capital improvements and/or base system replacements if needed. However, the building owner does not have to act on improvements identified in the Energy Audit report.


Step 3: Energy Efficiency Reports

In the final step of LL87 compliance, Partner Energy finalizes and submits the Energy Audit and Retro-Commissioning reports to the NYC Department of Buildings to attain compliance.


When do I have to comply?

Buildings must comply with LL87 every ten years based on its Borough, Block and Lot number. The last number of the tax lot number is the compliance year. (e.g. if the building’s Block number is 01228, compliance forms must be submitted in 2018, 20128, etc.)

Forms are due by December 31st of the compliance year.


What is the penalty for non-compliance?

Non-compliance results in a $3000 fine issued for the first year and a $5000 fine for every subsequent year. LL87 Reports will only be accepted once all fines have been paid in full.

Green Lending and Multifamily Incentives in the Greater NYC Area

Partner Engineering and Science’s, Melissa Dahl recently wrote an blog post encouraging borrowers to take advantage of green lending and multifamily incentives in the greater NYC area.

The multifamily green financing programs within both Freddie Mac and Fannie Mae have been extremely successful, with Fannie Mae closing on 500 green multi-family transactions through October 2017. Implementing green efficiency measures includes specific percentage reduction in water and energy use, benchmarking, and even air quality.


The demand for energy-efficient buildings in the commercial real estate market place is bigger than ever. There is a substantial shortage of energy-efficient properties, especially as more concrete data demonstrates the ROI of energy benchmarking and efficiency investments. This is resulting in more pressure from investors and tenants on pension funds and investment portfolios to have sustainable properties. There is more interest in improving existing stock: buildings certified as “green” or “efficient” increased from 5% in 2005 to 38% last year in the top 30 U.S. markets. There is even a new ASTM standard in the works for better energy efficiency in building roofs. Nowhere is this commitment towards efficiency more evident than in multifamily green lending programs. In their newly announced 2018 lending caps, Freddie Mac will be excluding Green Up and Green Up Plus loans, provided that energy and water usage are reduced by 25%. This is great news as Freddie’s green programs will not have to abide by the FHFA’s reduced lending caps and can therefore top their robust year in 2017.

Developers are betting big on energy-saving buildings

Energy efficiency, green building, green financing

Tony Liou weighs in on the new role energy efficiency plays in Commercial Real Estate:

In the past, institutional investors would qualify managers by investments and returns, according to Tony Liou, president of Partner Energy.

“Now it is, ‘What is your sustainability plan?’ ” Liou says. “They want to know what you are going to do to make [a building] more sustainable.”
