PRESENTATIONS
|
Bob Meade, New England District Sales Manager, RAB Lighting
Networked lighting controls (NLCs) use smart devices to combine six lighting control strategies in a way that maximizes savings. The six lighting control strategies are:
- Task tuning: setting a maximum light output that's less than a lamp's full capacity.
- Scheduling: setting lights to go on, off or dim at certain times of the day, week or year.
- Occupancy sensing.
- Daylight harvesting: reducing electric light levels when daylight is available.
- Dimming.
- Demand response: reducing light levels at times of peak electricity demand.
A facility manager with NLCs can, for example, set lights at 80% of capacity; automatically dim them further when natural light enters the room; and shut them off when the room is unoccupied.
Facilities that have installed NLCs have reduced their lighting energy costs by 38% to 60%.
Importantly, such systems can be wireless, which makes them relatively cheap and easy to install.
Lighting professionals can work with property managers to design and commission NLCs to optimize light levels in each space.
NLCs notify facility managers when lights burn out.

It's becoming more common for hotels to make cleaning chemicals onsite. By doing so, they eliminate the need to order chemicals, store them, dispose of the packaging and be concerned about expiration dates. They also reduce their purchasing costs.
Electrically-activated water (EAW) is one such set of products. At least several Boston hotels use similar cleaners.
Orbio's EAW products are certified by Green Seal, The Carpet and Rug Institute (CRI), the Toxics Use Reduction Institute (TURI) and others. They don't emit VOC's, thereby improving indoor air quality and reducing health risks for guests and staff.
Orbio customers install and use the company's equipment to make two products--a multi-surface cleaner and a hospital-grade sanitizer. Together, they can fulfill every cleaning need in a hotel.

Discussion
Ed Dustin, Mandarin Oriental Boston's Director of Engineering, said that his 10-year old hotel is going to undergo a retro-commissioning process. Several hoteliers discussed the optimal timing for retro-commissioning. The plurality said that it's sensible to retro-commission every seven to ten years.
Mr. Dustin also made the point that right now, remote monitoring of HVAC equipment has some limitations. So, it's still important for engineering staff to visually inspect their properties' machinery, and not completely rely on reports.

Reducing Plug Load Electricity is an Often Overlooked Opportunity
Facility managers appropriately focus on the biggest energy users in their buildings--HVAC, water heating and lighting. But studies show that plug and process loads (PPLs) can account for 25% to 50% of a property's electricity (not total energy) use. PPLs are electrical loads
not related to HVAC, water heating and lighting, such as computers and peripherals, TV's, ice machines, vending machines, coffee makers, water coolers, etc.
Organizations that strategically manage their PPLs can significantly cut their electricity use.
PPL energy can be trimmed by:
- reducing the number of PPL's in a facility.
- purchasing energy efficient PPL's.
- automatically turning PPL's off or down when not in use.
- getting users (staff and guests) to manually turn PPL's off or down.
Advanced power strips (APS) reduce energy waste in PPLs by automatically turning them off or down. They're inexpensive, and often have a return-on-investment of less than two years.
One can buy APSs that use schedule-timing, load-sensing or occupancy sensing.
Different equipment require different efficiency strategies. For example, schedule-timers are effective for equipment that should be left on without interruption during much of the workday, like water coolers. Occupancy sensors are indicated for equipment that can go into sleep mode periodically throughout the day, like computers and task lights.
It's wise to assign a PPL champion who can focus on reducing PPL expenses over time.
The following documents help facility managers cut PPL energy use:

Green Lodging Trends Report Survey Now
Open to Participation
Green Lodging News and Greenview have gone "live" with the 2017
Green Lodging Trends Report survey
.
Last year, over 2,000 properties in 40 countries took part.
Boston Green Tourism
is a Supporter of the Trends Report. I encourage you to participate, because the report is a great way to compare your property's green program against others.
The survey, which will close on June 15, consists of about 100 easy-to-complete questions. Participation is free.
After the close of the survey, a Green Lodging Trends Report will be produced that will analyze the results and highlight trends, exemplary practices and innovations. To access last year's report, click
