Dear Boston Green Tourism Members,

Our next meeting will be Thursday October 13, from 2:30 to 4:00 at Sheraton Boston Hotel, in the Fens Room, floor 5.
I thank our host, Jeff Hanulec.
I hope you can come!
Paul Van Kauwenberg, Associate Principal, Vanderweil Engineers 

Julia RogersSustainable Design Practice Leader, Vanderweil Engineers

Vanderweil Engineers is one of the leading U.S. engineering firm. Hospitality is one of its specialties. Their Boston area new hotel and renovation projects include Marriott Renaissance Waterfront, Hotel Commonwealth, Hilton Boston Downtown, Courtyard Boston Downtown, Copley Plaza Hotel and the new 
Envoy Hotel.

Mr. Van Kauwenberg and Ms. Rogers will discuss the Vanderweil approach and 
perspective on reducing energy and water use in hotels and other aspects of 

They'll describe how they reduce building energy loads through strategies like ventilation control and building envelope improvements; how to optimize building systems; and how hotels can add renewable energy. They will also discuss the products and systems that they find to be most effective. 

Ed Frechette, Chief Innovation Officer, United Teen Equality Center (UTEC)

UTEC, Inc is a mattress recycling organization based in Lowell that diverts unwanted mattresses from the waste stream. They deconstruct the pieces and recycle the component parts. 

First and foremost, UTEC, Inc is a youth services organization that helps young people with gang or court involvement turn their lives away from violence and poverty to social and economic success. They employ youth in social enterprises like mattress recycling to help them gain valuable work experience. 

Larry Whalen, Sales, Urell 

Mr. Whalen will describe modern water pumps that are smart, operate at variable speeds, require less maintenance than older units and have a long lifespan. The energy  savings are impressive and the payback period is short. 


Boston Posts 2016 Building Energy Data Online 
The Building Energy Reporting and Disclosure Ordinance (BERDO), "requires Boston's large and medium-sized buildings to report their annual energy and water use to the City of Boston, after which the City makes the information publicly available."
Energy and water use data for 1500 Boston commercial buildings were just posted online and on an interactive map. I counted 44 hotels on the report--and the data was clearly problematic for seven of them. Some hotels aren't listed. Perhaps they didn't submit their data.
The metrics include Energy Use Intensity (kBTU / square foot); Energy Star Portfolio Manager score; the proportion of energy use attributed to electricity, natural gas and steam; water intensity (gallons / square foot); and more.
Cambridge will post similar information for the first time before the end of the year.
Portfolio Manager rates hotels from 1 to 100. The range for Boston hotels approximates the bell curve.
Keep in mind that Portfolio Manager scores, like every other rating system, is imperfect. It's impossible to accurately compare the scores of hotels that have different features, operations and clientele. Portfolio Manager accounts for some variables, but not all.
Also, some believe that the high price of Boston hotel rooms has increased the number of occupants per room. Higher room occupancy results in more showers, busier kitchens--and thus higher energy intensity and lower Portfolio Manager scores.
The EPA is revising the lodging industry's Portfolio Manager rating system, as reported in this newsletter. The new system will probably boost the scores for full-service properties.
I offer a (free) workshop for BGT members that helps hotels reduce energy use and green their properties in other ways. It's based on the strategies and practices used by successful U.S. hotels. Contact me if you're interested.

Conveyor Dishwasher Performance Field Evaluation Report

Amin Delagah, Angelo Kara, Rodney Davis, David Zabrowski, Fisher-Nickel, Inc., for the Pacific Gas and Electric Company  Food Service Technology Center, December 2015. 

Glenn Hasek, Green Lodging News, September 8

This 98-page report, based on an extensive study, corroborates the Hobart / ITW Food Equipment speaker at our September 8 meeting who said (in this presentation) that new, efficient dishwashers cut energy and water use by more than half. In the study, replacing old dishwashers with Energy Star units resulted in a 70% reduction in water use and 55% reduction in energy use.

The authors found that dishwashers become more inefficient over time. Hotels that don't replace their old units would benefit from having them retro-commissioned. Even new units benefit from timely maintenance. By submetering water use, problems are often identified promptly. 

Proud Green Building, April 25

Sensors, lighting controls, dimming and shading systems work together to create ideal lighting levels for work, dining and other activities. By reducing light levels appropriately, hotels save money and create more comfortable, pleasing rooms. 

Recent BGT presentations on window shades and lighting controls are here and here.


The following meeting will be 2:30 to 4:00.
