We tweeted this the other day, but I thought it was worth more attention. Build2Sustain seeks to become a leader in sustainable retrofit and renovation for commercial spaces. This story is a prime example of what's possible with intelligent retrofit.

Caterpillar Headquarters in Peoria Ill. underwent a retrofit focused on efficiency. Here are some of the highlights:

-Caterpillar’s headquarters will save about $800,000 a year in energy costs.

-Tom Gerike, Engineering Project Team Leader, provided the following: Previously, the building’s annual energy usage of electricity and natural gas was 111,591 MMBTU. Now, it uses 60,622 MMBTU.

Some Key Retrofit Features:

From Gerike:

There was no night setback in place for HVAC equipment or for lights,” he said, adding that consistent setpoints were established at 70 degrees in the heating season and 76 degrees in the cooling season.

From The Environmental Leader Article:

For lighting automation, the new system has smart breaker panels controlled by a lighting schedule with pushbutton overrides for common areas. Also, motion sensors were installed into private offices and conference rooms.

As a result of these improvements the site earned LEED Gold Certification. What's missing from this story is project ROI and payback periods of the renovation. We're working to get that info and hopefully will have it for you soon. In the meantime, for more on the retrofit, read the entire story at Environmental Leader or see Caterpillar's Press Release for more.

In the latest two-step from NYC on the subject of green building, here's the latest bill to pass (as reported by LightNow)

Some highlights (again, thanks to LightNow for the run down):

Int. No. 973-A: Legislation that requires large commercial buildings (over 50,000 square feet) to upgrade their lighting and sub-meter tenant spaces over 10,000 square feet;

Int. No. 564-A: Legislation that creates a New York City Energy Code that existing buildings will have to meet whenever they make renovations (closing the loophole that allows buildings to perpetuate non-compliant systems if they perform renovations on less than half of a given building system);

Int. No. 476-A: Legislation that requires large buildings owners to make an annual benchmark analysis of energy consumption so that owners, tenants, and potential tenants can compare buildings’ energy consumption; and

Int. No. 967-A: Legislation that requires large private buildings to conduct energy audits once every decade and implement energy efficient maintenance practices. Also, all city-owned buildings over 10,000 sq ft will be required to conduct audits and complete energy retrofits that pay for themselves within 7-years.

I don't have a ton of time this morning for commentary, but look for more tonight. We specifically mentioned NYC legislation initiatives in our white paper. This update only strengthens the argument that businesses are soon going to face one of two options, meeting energy requirements on their own terms, or have their arms twisted. Build2Sustain advocates the former.

Look for more on the bill from our blog later this week.
