Multifamily Housing at Continental Plaza, Chicago

Continental Plaza is an example of how energy and water upgrades can help preserve affordable housing while reducing carbon emissions and conserving natural resources. Using ACE, Inc.’s innovative, mission-driven energy service company model, Continental Plaza reduced its annual utility costs by over $47,000 under the shared-savings agreement—a 15 percent utility cost reduction. A building owner who receives all of the energy and water cost savings could have seen its 2014 utilities reduced by as much as $109,282. (Note: ACE Inc. was the Hispanic Housing Development Corporation subsidiary that pioneered ACE’s model and of which Jeff Greenberger was COO at the time.)

Dear investors and followers,

We are approaching the end of ACE's crowdfunding campaign! This is your last chance to be part of ACE’s mission to help low-income housing communities and the planet.

ACE is more than thankful for your emotional support, yet we do hope to get your monetary investment, too. As we continue with the $6 million project with Mercy Housing in the coming year and expect a financial return, a substantial working capital would help us to make sure that we deliver the best service. This means that every investment you make would be of great value to ACE and our mission!

Please take this last chance and invest in ACE today.

We appreciate your help.

Time is running out. Invest in ACE now!

Dear StartEngine Followers,

Thank you for being a part of ACE's crowdfunding campaign over the past few months. We are heartened by your interest in improving lives for low-income communities and for protecting our environment—which, as you know, is at the heart of ACE's work. We are closing our campaign in TWO days! That’s two days left for you to invest in ACE and put your money where your values are!

As a mission-driven energy services company providing comprehensive green retrofits to low-income housing, ACE has completed important work over the past few years. Happily, ACE just obtained a commitment for a $3 million financing commitment for our $6 million California project. But it has been a long haul and we still need to increase our working and growth capital. We hope you will continue to be part of the ACE family. Your support, both emotionally and monetarily, is greatly appreciated. Our minimum investment amount is only $250, but please give more if you can. 

Feel free to leave us a comment if you have any questions.

ACE appreciates your support.

ACE secured $3 million loan to proceed with the Mercy Project

Dear investors and followers,

We have tremendous news to report: ACE has found its financial partner! As a result, we will be able to deliver meaningful sustainable benefits to approximately 6,000 units of low-income housing and the odds that this investment will be financially rewarding have greatly increased.

The Loan Committee of the Reinvestment Fund has approved a $3 million loan to ACE that will allow us to complete the comprehensive retrofit of approximately 90 multifamily affordable housing properties owned by Mercy Housing in California.

This loan approval will have several game-changing impacts:

  • Reinvestment Fund is making this loan in part because it believes that this will be a new line of business; it is not only prepared, but expecting, to make additional loans to ACE for future projects. It appears that we have finally found our “checkbook.”
  • ACE will be receiving substantial and sustainable revenue generated by the Mercy Project.
  • Obtaining this loan and the long-term commitment from Reinvestment Fund substantially reduces the risks associated with your investment in ACE.
  • By completing this loan and commencing the Mercy Project, ACE will have demonstrated to other owners of multifamily affordable housing that ACE can deliver, which will make future business development easier.

We are extremely excited about 2018 and beyond as a result of this news. For those of you who have invested in ACE, we thank you for your support; we couldn’t have gotten here without you. And for those of you who haven't, we welcome you to be part of ACE's future. Please consider investing in ACE and share this opportunity with people who have the same passion as us. We appreciate your help.

ACE Joins DOE Residential Network

Happy New Year investors!

At the beginning of this year, ACE has a list of exciting news to share with you. And here is the first one:

ACE has become a new member of the U.S. Department of Energy (DOE) Better Buildings Residential Network, which connects energy efficiency programs and partners to share best practices and learn from one another to increase the number of homes that are energy efficient.

ACE will benefit immediately by receiving access to monthly topical calls with peers about residential energy efficiency strategies. Calls have discussed business partners and workforce development, marketing and outreach, evaluation and data collection, financing, moderate- and low-income markets, and so on.

Joining the Network will provide ACE more opportunities to establish itself in the energy efficiency industry and to jointly work with other organizations to make affordable housing affordable and the planet livable.

For more details, please read the press release at:


Notice of Funds Disbursement

[The following is an automated notice from the StartEngine team].


As you might know, Affordable Community Energy Services Company (ACE) has exceeded its minimum funding goal. When a company reaches its minimum on StartEngine, it's about to begin withdrawing funds. If you invested in Affordable Community Energy Services Company (ACE) be on the lookout for an email that describes more about the disbursement process.

This campaign will continue to accept investments until its indicated closing date.

Thanks for funding the future.



We reached our minimum funding goal!

Recently, with the help of our investors, we passed our initial goal of $10,000! We thank you for supporting our mission.

Still there's plenty of work to do.

If you haven't invested yet, please consider doing so.

If you have invested, please spread the words for us and urge your friends to do so, too.

Doing good to the low-income housing communities and our environment requires a lot more than what we have now.

And there are less than 2 months left for our campaign.

We need your help more than ever!


ACE is making exciting progress and calling for more support!

Welcome to our new investors and followers. To all of you, thank-you for supporting ACE’s mission to help low-income housing communities and to protect the environment!  Now that you are part of ACE's movement, we want to keep you updated on our work:

•  Crowdfunding Progress, but a Long Way to Go.  After launching our crowdfunding campaign, we've received additional investments and commitments of almost $20,000 from more than 15 investors. We are still waiting for some investors to finalize their investments on the StartEngine platform, but with all the commitments, we are exceeding the minimum funding goal set with the platform. But this was an arbitrary minimum, we have as our goal to raise between $200,000 and $500,000 to provide the additional liquidity that will be required as ACE moves on to new projects.

•   Term Sheet with A Project Lender. The good news is that we have signed a Term Sheet with the Reinvestment Fund to provide the project loan for the $5.5 million Mercy California Project.  While we still have details to iron out, RF is aiming for a loan committee meeting in late November.  We are working diligently, and hope to close the loan by early in 2018.

•   More Visibility for ACE’s Work.  ACE has been cited as an industry pioneer, tapping into social impact investors like you to help fund energy efficiency for low-income housing. Check out the press coverage here.

We are very positive about our progress in our core business and in the preliminary results of our crowdfunding campaign, but we still have an urgent need to raise additional funds to provide the liquidity required to strengthen ACE’s balance sheet. This will help us reach more low-income individuals and families and to grow our business.

Please join us in the cause and share your support with those whom you think our mission might resonate. And if you haven’t yet invested, please do so now.

Thank you for being part of GOOOD to the Power of ThreeTM.

Invest in over 200 start-ups and collectibles!

With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors.

With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000, are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, he/she is limited to investing 10% of the greater of the two amounts.

At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.

Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.

StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.

For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.

For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.

Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.

Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.

Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements. To learn more about Regulation Crowdfunding, click here, and for Regulation A+, click here.
