Will your boiler replacement pay for itself?

Two weeks ago, Nate detailed the Worcester Housing Authority’s boiler upgrade and cogen installation. Today I’m going to share a second boiler replacement success story, and then discuss why we're seeing such great results from these upgrades. We’ve been asked not to disclose the building name or any specific characteristics for this project. Feel free to comment with a specific question, and I’ll try to answer the best I can.

San Francisco Energy Efficiency Ordinance

Earlier this month we wrote blog posts about benchmarking ordinances in NYC and Seattle. In February, San Francisco joined the ever growing list of cities enacting benchmarking laws with the Existing Commercial Building Energy Performance Ordinance. The city hopes the ordinance will encourage commercial buildings to invest in energy conservation measures and reduce the city's overall carbon footprint. As detailed in the chart below, a small reduction in GHG emissions in the commercial sector could go a long way toward helping the city achieve its emission reduction goals.

In an effort to reduce the emmissions of existing buildings by 20% before 2020, the city of Seattle will require owners of all large commercial and multifamily buildings to benchmark, disclose and report their energy usage data on a yearly basis.

Case Study: Water Conservation Best Practices

Last week we wrote about water performance in multifamily buildings and mentioned the deep savings opportunities around water conservation. This week we want to highlight a progressive building owner who took the time to figure out which of their buildings were performing poorly, get a water audit and then enact the recommendations of the audit.

Building Metrics: The Commercial Building's Equivalent to the MPG

The Commonwealth of Massachusetts' roadmap to address the threat of global warming, the 2008 "Global Warming Solutions Act," calls for an 10-25% statewide reduction in greenhouse gas emissions by 2020. Much of this reduction must come from the commercial and industrial buildings, as they account for over half of the state's energy use.  Massachusetts is proposing to develop and implement a building energy labeling program that includes both asset and operational energy ratings.  The Department of Energy Resources (DOER) issued this report, which outlines salient issues and strategies.
