NEII® PERFORMANCE STANDARDS COMMITTEE
April 15, 2014 1. Call to Order. Chairman Joe Busse called the meeting to order at 8:30 a.m. on April 15, 2014 at Fujitec America, 7258 Innovation Way, Mason, Ohio 45050. 2. Record of Attendance.
Name Company Brian Black NEII Barry Blackaby Otis Elevator Company Jeff Blain Schlindler Elevator Company Joe Busse Fujitec America Bob Caporale (teleconference) Elevator World Doug Henderson ThyssenKrupp Elevator Corporation Tom Hausenbauer NAEC (Minnesota Elevator Inc.) Mike Lewis KONE, Inc.
3. Announcements. Jay Popp was unable to attend the meeting. 4. Adoption of Agenda. The agenda posted on the committee website was adopted. 5. Approval of October 8, 2013 Minutes. The minutes posted on the committee website were approved. It was noted that Jay still needs to draft a paper on elevator‐specific provisions for LEED certification. Barry will assist on this. Brian will follow up on the A17.1 vs A117.1 white paper.
6. Personnel.
Please see Attachment #1 for a copy of the Committee Roster. Members are requested to advise Brian Black of any corrections that are required.
7. Election of Chairman. Barry noted Joe’s chairing the committee gives them an opportunity to discuss electrical matters when they cannot all attend an A17 Electrical Committee meeting. This item is tabled until the next meeting. 8. Destination Dispatch. a. Performance criteria. The committee reviewed Attachment #2. Jeff offered Attachment #3 and Attachment #4 for review and discussed average‐time‐to‐destination being a metric that did not seem to work well. Average‐number‐of‐intermediate‐stops (2‐3 ideal) is a better benchmark as is average‐time‐to‐service. Bob noted that different algorithms used by different companies make a comparison difficult for the consultants. He also suggested that buildings and traffic patterns have become more complex because destination dispatch permits this. Doug noted the average waiting time and travel time have been constant metric in the industry for both conventional and destination systems, and stated we shouldn’t complicate this too much in NEII‐1. Barry mentioned an ISO working group has been formed to standardize destination dispatch definitions. Joe suggested we use the term “IS” for intermediary stops and standardize our definitions and terminology. He also asked Bob and Jeff to raise this at the IAEC Forum in Denver next week. Bob will develop an example of the approach used by the consultants to discuss at our next meeting. Barry will ask Theresa Christy to get involved as well. Bob raised the question of whether we should provide performance metrics in NEII‐1. Doug asked whether we should come up with a percentage of reduction of time over conventional systems. He also suggested we could develop some general performance criteria that can be applied to both conventional and destination dispatch systems.
The committee agreed that hybrid systems should also be addressed. b. Accessibility criteria. The committee agreed to abandon the approach shown in Attachment #5. Attachment #6 will serve as the basis of the more general requirements of our NEII‐1 Guidelines. c. ASME A17.5. Barry noted the destination dispatch hall call consoles are “operating devices” as specified in the scope in A17.5 and that this is problematic, particularly for features like touch screens. 9. Part 7, Maintenance Guidelines. Barry reported the Doug LeBrecque wrote an article on MCPs for NEII Now (Attachment #7) that can be used as a foundation for the NEII‐1 piece. 10. Energy Efficiency. a. ASHRAE 90.1‐2010 and 2012 Supplement. Brian reported ASHRAE 90.1 now references A17.1/B44 for specifications on reduced‐speed escalators and moving walks as shown in Attachment #8. b. ISO TC 178/WG10 progress.
Barry reported ISO 25745 Part 2 is completed, providing a rating criteria on a per elevator basis. The final draft will be posted on NEII Talk. ASHRAE 90.1 will reference this once it’s published. Barry will look at the NEII‐1 Energy Efficiency Standard and suggest changes to include references to the ASHRAE 90.1 provisions. Bob forwarded a letter from ACEEE (Attachment #9) regarding a White Paper on energy efficiency and elevators. Barry offered to represent NEII on their Advisory Committee.
11. NEII®‐1 Publication.
NEII®‐1 is on the NEII web site, http://www.neii.org/neii‐1/neii‐1.cfm. 12. Review and Update of NEII®‐1 Parts 1, 4, 5, 6 and 7.
The standards with revisions approved to date are posted in the NEII®‐1 folder on the NEII® Performance Standards Committee web site. Committee members should down load and/or print copies of the latest drafts in advance of the meeting.

a. Performance Terminology Matrix Examples. Jeff will review Attachment #10 for
the next meeting. Mike will draft an item for power factor. b. Performance Standards Matrix New Escalator and Moving Walk. Barry will review Attachment #11 for the next meeting.
c. Vibration Diagrams. Barry will review Attachment #12 for the next meeting. 13. Review NEII® Long Range Plan – Performance Standards Committee.
The committee reviewed and reaffirmed Attachment #13.
14. New Business. a. Occupant Evacuation Elevators. Barry will ask David McColl for a paper/article. b. Starts‐per‐hour specifications. Joe indicated this has been raised as a concern by some consultants, as has temperature rises/insulation classes. He will draft a paper for consideration.
c. Independence and redundancy. Joe noted that we have had problems with TSSA regarding the Normal Terminal Stopping and the CCC was going to draft a letter. Doug reported the Canadian firms were considering a formal complaint and suggested we hold off on any action until that runs its course. d. OSHPD and seismic issues. The committee discussed the experiences some companies were having with OSHPD and its inspectors. Joe suggested this topic is best covered by the Central Code Committee. e. Green technology (e.g., regenerative drives). This item was tabled until the next meeting. f. Review of mainline disconnect switch provisions in the guidelines. Mike will review this item. 15.

Draft of Destination Oriented Elevator Performance Criteria
By Robert S. Caporale
April 12, 2013
The elevator core may comprise as much as 15%-20% of a
building's floor area therefore determining the proper size
and the number of elevators is an important aspect of
building design. Providing too few elevators can seriously
compromise a building's efficiency and marketability. And
designing a building with more elevators than needed is bad
economics. Therefore a proper and thorough elevator system
traffic analysis must be performed for the elevator
arrangement being proposed.
The number of people served in a given time period is
generally defined as a group of elevator's Handling
Capacity (HC). This HC must be equal to or greater than the
rate at which people arrive at the elevator group to obtain
service.
The passenger arrival rate will be a function of the
building's occupancy, usage and location. Examples of this
are shown in Table 1 which describes the 5-Minute Handling
Capacity (5-Min HC) that an elevator system must be able to
ATTACHMENT #2 Page 1 of 5
2
achieve for various elevator passenger arrival rates that
can be expected for various types of buildings.

Self-parking Garage

Department Store 60 8-10 Industrial Bldg. 40 12 Table 1: Passenger Arrival Rates
*100% of the population arrives in this number of minutes
The NElI-1 Elevator Performance Standard defines the
“Average Waiting Time (AWT)”, “Average System Response Time
(ASRT)” and “Average Time to Destination (ATTD)" for a
destination oriented elevator system as well as how these
quantities are measured.
When traveling on a destination oriented elevator system a
passenger might have to wait a bit longer than anticipated
for an elevator to arrive in order to get one that will
provide them with a shorter overall trip time to their
ATTACHMENT #2 Page 2 of 5
3
destination. The ATTD that is calculated for a destination
oriented elevator system reflects this as it includes the
time that a passenger can be expected to wait for an
elevator to arrive plus the actual time that they will
travel in an elevator to their desired destination.
With destination oriented elevator systems, the 30-second
interval is no longer a valid measurement of the quality of
service. Instead each passenger's entire elevator trip
experience is considered and the important criteria that
the system must be able to satisfy is the ATTD. Therefore,
when evaluating the quality of elevator service for a
destination oriented elevator system it is necessary to
understand and for the elevator traffic analysis to reflect
this new measure of elevator service.
As previously stated, the 5-Min HC of an elevator system
must be able to accommodate the passenger arrival rate. An
appropriate ATTD must also be achieved for the type of
building in which the elevators will be installed. As long
as the 5-Min HC of the system matches or exceeds the peak
5-Mininute passenger arrival rate and the proper maximum
ATTD is not exceeded the elevator system will provide
adequate elevator service.
ATTACHMENT #2 Page 3 of 5

The ATTD and 5-Min HC criteria that should be achieved for
destination oriented elevator systems in various types of
buildings are shown in Table 2.
Type of Building ATTD (Seconds) 5-Min HC (Percent) Business District Office Bldg. Multi-tenant
100–120 12

Suburban Office Bldg.
100–120 8–10
Self-parking Garage 60 8-10 Department Store 80 12 Industrial Bldg. 120–150 12 Table 2: Destination Dispatch Performance Criteria
The performance criteria must be agreed upon by the
building’s owner and their architects and elevator
consultants as well as the elevator contractor. Traffic
analysis calculations should be developed and made a part
of the elevator project’s documentation.

Standards and Recommendations
Depending on the type of building, one or two of the following traffic situations are analysed:
Traffic Situation Incoming Outgoing Inter-floor Type of Building
Up-Peak 100 % 0 % 0 % Office (all)
Lunch (Single Tenant) 40 % 40 % 20 % Office (single-tenant)
Lunch (Multi-Tenant) 45 % 45 % 10 % Office (multi-tenant)
Two-Way Hotel 50 % 50 % 0 % Hotel
Two-Way Residential 50 % 50 % 0 % Residential
For other types of buildings, an Up-Peak situation and optionally one of Lunch Single Tenant, Lunch
Multi-Tenant, or Two-Way Hotel are analysed.
Every analysis covers a full range of arrival rates, reporting handling capacity HC5 and average waiting
time WT as main criteria. As a general guideline, Schindler defines a rating in the range of 0.0 (worst) to
6.0 (best) based on these criteria. Recommended ratings are 3.0 or higher:
Schindler Traffic Analysis Ratings 2008
Rating >= 3.0 Rating >= 4.0 Rating >= 5.0
Traffic Situation HC5 WT HC5 WT HC5 WT
Up-Peak >= 12 % <= 30 s >= 14 % <= 20 s >= 16 % <= 15 s
Lunch (Single Tenant) >= 11 % <= 40 s >= 13 % <= 30 s >= 15 % <= 20 s
Lunch (Multi-Tenant) >= 11 % <= 40 s >= 13 % <= 30 s >= 15 % <= 20 s
Two-Way Hotel >= 11 % <= 40 s >= 13 % <= 30 s >= 15 % <= 20 s
Two-Way Residential >= 6 % <= 80 s >= 7 % <= 60 s >= 8 % <= 40 s
Ratings are also displayed by a corresponding number of stars and may be interpreted on a global basis
as follows:
Rating Stars Office Hotel Residential
>= 3.0 Standard office buildings Up to approx. 3-star hotels Basic segment
>= 4.0 Mid-to-higher requirements Up to approx. 4-star hotels Medium segment
>= 5.0 Premium sites Up to approx. 5-star hotels Premium segment

How Schindler Undertakes Traffic Analyses
4.1 Introduction
A traffic analysis studies the performance of a group of elevators, based on assumptions about the
expected traffic situation. The main performance measurements are handling capacity and waiting time.
Reliable and comparable performance results are found by means of benchmark simulations which reflect
the expected real behavior of a group of elevators under a wide range of traffic situations.
4.2 Measures and Definitions
The elevators' main task is to manage the traffic, i.e., the transportation needs of passengers and goods, in
such a way that the highest possible density of arriving passengers and goods can be transported in the
building at the highest possible perceived service quality.
4.2.1 Arrival Rate and Handling Capacity (P5, HC5)
For a specific elevator group, the arrival rate describes the density of arriving passengers in an observed
time period. In contrast, the handling capacity is the number of passengers transported in an observed
time period. As long as the elevator group is able to transport all the arriving passengers without building
up waiting queues, the arrival rate and the handling capacity are equal.
Handling capacity is measured by P5 and HC5:
P5 is the number of persons that is transported on average within 5 minutes.
HC5 is the percentage of the population on the floors served by the elevator group that is
transported on average within 5 minutes:
HC5 = P5 / (population on floors served by elevator group).
Example: Consider an elevator group which serves floors with a population of 1000 people. By
observation, there are 600 passengers transported within 30 minutes, therefore:
P5 = 600 persons * (5 minutes / 30 minutes) = 100 persons,
HC5 = 100 persons / 1000 persons = 10.0 %.

4.2.2 Waiting Time (WT) and Destination Time (DT)
Waiting time and destination time for an individual passenger are defined as follows:
waiting time: time from when the passenger registers a landing call (or joins a queue) until the
door of the serving elevator begins to open on the boarding floor (zero if the door is not closed
when the passenger arrives)
destination time: time from when the passenger registers a landing call (or joins a queue) until the
door of the serving elevator begins to open on the destination floor
Call registration Door starts to open at board
floor
Car is leaving the board floor Door starts to open at
destination floor
Waiting Time Board Time Travel Time
Destination Time
For a number of served passengers in an observed period of time, the average waiting time WT and the
average destination time DT are defined in the usual way as mean values of the passengers' individual
waiting time and destination time, respectively.
4.2.3 Number of Intermediate Stops (IS)
The number of intermediate stops for an individual passenger is the number of times an elevator stops with
the passenger between boarding floor and destination floor. For example, for a passenger with a direct
(non-stop) trip from boarding floor to destination floor the number of intermediate stops is zero.
For a number of served passengers in an observed period of time, the average number of intermediate
stops IS is defined in the usual way as mean value of the passengers' individual number of intermediate
stops.

4.3 Methods of Traffic Analysis
A traffic analysis should cover a variety of important traffic situations, especially when planning new
buildings. Reported values should be as reliable and comparable as possible. However, performance
values depend on the methods of the traffic analysis and the basic traffic assumptions.
4.3.1 Simulation vs. calculation methods
In simulation methods, a real passenger flow is being replaced by a virtual one, which was created with the
help of a random generator and loaded into the same control algorithm as used in a real elevator
controller. Thus the results can be measured under different traffic conditions and reflect the expected
reality to a very large extent.
In contrast, calculation methods are based on formulas which only cover a very limited range of traffic
situations (usually, only up-peak traffic). The formulas reflect theoretical assumptions rather than a realistic
behavior of elevator groups, and results are usually too optimistic. Therefore, calculation results should not
be compared with simulation results.
Schindler Traffic Analysis Reports are based on simulations in order that the reported results are the most
reliable and realistic achievable.
4.3.2 Wide Range of Traffic Assumptions
The traffic flow in a building keeps changing all the time; no two days are the same. As a rule, traffic
depends on many factors (such as location of building, tenant structure, etc.) and may vary considerably
during operation of the building. A traffic analysis should take such factors into consideration and try as far
as possible to cover future traffic situations.
In a complex building, a single traffic assumption is not sufficient. E.g., it is not sufficient to apply a traffic
pattern measured in some other existing building for the design of a new building. In particular, the limits of
the handling capacity of the elevators cannot be found by such "spot light" examinations.
Predictions about the range of handling capacity of an elevator group can only be made by actually
simulating a wide range of traffic situations. A benchmark method applies a reference traffic situation from
low to very high traffic intensity; by this, the limits of the elevators' handling capacity can be detected.
Schindler uses a benchmark method which gives a neutral system assessment.
Schindler Traffic Analysis Reports are based on different traffic situations (see Section 2) tested by
benchmark methods. This ensures that the traffic analysis covers a full range of applications and reports
reliable and comparable performance predictions.

407 Elevators
This document is a draft proposal for expanded accessibility requirements for destination dispatch (destination-oriented) elevators. In accordance with NEII® policy it is based on the national consensus standard ICC/ANSI A117.1-2009, and incorporates the numbering and format of that standard.
This draft is not in precise legislative format as some of the existing standard’s text that does not apply to destination dispatch systems has been removed and not displayed in strikeout. For those sections where all of the text was deleted, the term “Reserved” is used to maintain the standard’s existing numbering system.
New requirements are derived from proposals to the A117 Committee that were considered by the NEII® Central Code Committee, provisions of the San Francisco Administrative Bulletin AB-090 on Destination-Based Elevator Control Systems, and comments by NEII® representatives on that Administrative Bulletin.
407.1 General. Elevators shall comply with Section 407 and ASME A17.1/CSA B44 listed in Section 105.2.5. Elevators shall be passenger elevators as classified by ASME A17.1/CSA B44. Elevator operation shall be automatic.
Existing A117.1 text.
407.2 Elevator Landing Requirements. Elevator landings shall comply with Section 407.2.
Existing A117.1 text.
407.2.1 Call Controls Interface Consoles. Where elevator call buttons or keypads car control interface consoles are provided, they shall comply with Sections 407.2.1 and 309.4. Call buttons shall be raised or flush. Objects beneath hall call buttons shall protrude 1 inch (25 mm) maximum.
San Francisco refers to “keypad consoles”. This is expanded to “interface consoles” to accommodate provisions for touch-screen displays.
407.2.1.1 Height. Call buttons and keypads shall be located within one of the reach ranges specified in Section 308, measured to the centerline of the highest operable part.

407.2.1.2 Reserved. [Size]. 407.2.1.3 Clear Floor Space. A clear floor space complying with Section 305 shall be provided at call controls.
Existing A117.1 text.
407.2.1.4 Location. At elevators available for public use, at least one car control interface console shall be wall-mounted for each elevator group, located between two hoistway entrances for the elevator group.
This is derived from a San Francisco requirement that specifies a keypad console be located adjacent to a hoistway opening where a conventional hall call might be. It is restricted to elevators available for public use because passengers in restricted buildings will be familiar with where the hall call stations (if provided) are located.
407.2.1.5 Signals. Car control interface consoles shall audibly indicate when an invalid key press sequence or incorrect floor selection has been entered.
This is derived from a San Francisco requirement.
407.2.1.6 Interface Console. Interface consoles shall include a keypad, an accessible touch-screen display, or both.
This specifies that both keypads and touch-screens are permitted.
407.2.1.6.1 Keypads. Where keypads are provided, keypads shall be in a standard telephone keypad arrangement and they shall comply with Section 407.4.7.2 407.2.1.6.1
ATTACHMENT #5 Page 2 of 13
407.2.1.6.1.1 Arrangement. Keypads shall be in a standard telephone keypad arrangement, except that the bottom left key shall have a star complying with Table 407.4.7.1.3 and the bottom left key shall have a minus (-) sign.
The standard telephone keypad is moved from 407.2.1.6.1, above. The addition of a star key and a minus key is standard industry practice.
407.2.1.6.1.2 Size. Keypad keys shall be ¾ inch (19 mm) in the smallest dimension.
A flaw in the existing A117.1 is that it specifies a ¾ inch (19 mm) key size for keypads located inside elevator cars but is silent on key sizes for hall call. This corrects that omission.
407.2.1.6.1.3 Identification. Keypad keys shall be identified by visual characters complying with Section 703.2 centered on the corresponding keypad button. The number five key shall have a single raised dot. The dot shall have a base diameter of 0.118 inch (3 mm) minimum and 0.120 inch (3.05 mm) maximum, and a height of 0.025 inch (0.6 mm) minimum and 0.037 inch (0.9 mm) maximum.
This is existing A117.1 text from section 407.4.7.2 that applies to keypads.
407.2.1.6.1.4 Operation. Keypads shall be mechanical. The force required to activate the keys shall be 0.5 pounds (2.5 N) minimum and 1.25 pounds (5 N) maximum.
This is derived from the ISO 4190-5 requirements for accessible controls.
407.2.1.6.2 Accessible Touch-Screen Displays. Where touch-screen displays are provided they shall comply with 407.2.1.6.2.
The NEII® Central Code Committee has expressed an interest in expanding the standard’s current destination dispatch requirements to specifically recognize accessible touch-screen systems.
407.2.1.6.2.1 Verbal cues. Upon activating a function button a touch screen display shall announce the available
This provision is a modification to the San Francisco Administrative Bulletin that has been recommended by a NEII® representative. It permits a blind or visually impaired passenger to input a hall call without having to use or touch the display

Requiring the touching of specific controls on a screen to make a floor selection shall not be permitted when a function key has been activated.
screen.
407.2.1.7 Destination-oriented Elevator Signals. Destination-oriented elevators shall be provided with a visible signal and audible tones and verbal announcements to indicate which car is responding to a call. The audible tone and verbal announcement shall be activated by pressing a function button. The function button shall be identified by the International Symbol for Accessibility and a raised indication. The International Symbol for Accessibility, complying with Section 703.6.3.1, shall be 5/8 inch (16 mm) in height and be a visual character complying with Section 703.2. The indication shall be three raised dots, spaced 1/4 inch (6.4 mm) at base diameter, in the form of an equilateral triangle. The function button shall be located immediately below the keypad arrangement or floor buttons.
Existing A117.1 text. It would make sense to place the Function Button in a more prominent place in an editorial revision of this draft, as the function button serves as the “portal” to all of the accessibility functions of a destination dispatch system. Whether a hall call is placed with a traditional mechanical keypad or an accessible touch-screen with voice cues, the user needs to know that every destination system he encounters will have a function key to guide his use of the system.

In late 2013, the ASME A17.1-2013/CSA B44-13 elevator code will be issued, and will become effective 6 months later. Although there are a number of changes in this revision to ASME A17.1-2010/CSA B44-10, a significant one has occurred with the Maintenance Control Program (MCP) and associated Maintenance Records in Section 8.6. A task group of individuals representing different sections of the A17.1/CSA B44 code, worked over 2-1/2 years, to better clarify and define what makes up a MCP. This included what records are required, what do they include, along with their on-site view ability to elevator personnel. There is new non-Mandatory Appendices added, explaining how these parts of the MCP and records are accessed, along with a sample Records Log. It is beneficial for you to review through these new requirements, to understand the details and to be prepared for this new Code. Details of the changes include new definitions for terms used in this section and a complete rewrite of Requirements 8.6.1.2 and 8.6.1.4; and updates to other requirements referencing these sections. Specific modifications are:
Requirement 8.6.1.2.1 defines what a MCP is and that it is to be provided by the person or firm maintaining the equipment. This MCP can be kept remotely from the site, but must have instruction for how it can be located for viewing on-site, from the time of Acceptance Inspection. The MCP will include the maintenance tasks, procedures, examinations and tests for the equipment; with their associated requirements in 8.6.4 through 8.6.11. Each of these will also have an interval, which may be impacted by such things as age, usage, and improved technology, as was previously in the Code.
Requirement 8.6.1.2.2 is new, defining On-Site Documentation. This specifies what must be kept on site;
o wiring diagrams, o those specific procedures that require a written procedure on site by
Code, o Unique Procedures, also as defined in the Code, for SIL rated E/E/PES
electrical protective devices and circuits or as specified in A17.7/B44.8 Code Compliance Document. These must be available at Acceptance Inspection.
Requirement 8.6.1.4 defines all of the Maintenance Records. These records must be able to be viewed on-site, but can be stored off-site. Instructions for viewing them must be posted on the controller or means necessary for test. The records are:
o MCP Records: Those tasks defined in the MCP for this unit with the associated interval, Service Provider, date of work done, description of the task and associated 8.6 requirements.
o Repair and Replacement Records: This the date, person and/or firm and description of the Repair or Replacement; as defined in Section 8.6 as a ‘Repair’ or ‘Replacement’ or includes a component or device in 8.6.4 through 8.6.10.
o Other Records: These records specifically called out in the Code to be on-site (Oil Usage, Firefighter Emergency Recall Operation findings, Periodic Tests, and replacement criteria on less than 8mm ropes).
o Callbacks (Trouble Calls): These records need to be available to elevator personnel who are performing corrective actions. These may be in hard copy or electronic; but are not required for on-site viewing. Instructions for reporting callbacks need to be located onsite.

FOREWORD
The 2010 edition of the ASME Safety Code for Elevatorsand Escalators added allowances to permit varying the speedof escalators and moving walks to conserve energy. It does notyet permit automatically stopping and starting of escalators ormoving walks. Variable-speed technology is common for thisapplication in other countries.
Note: In this addendum, changes to the current standardare indicated in the text by underlining (for additions) andstrikethrough (for deletions) unless the instructions specifi-cally mention some other means of indicating the changes.
Revise the standard as follows (I-P and SI units):
10.4.4 Escalators and Moving Walks. Escalators andmoving walks shall automatically slow to the minimum per-mitted speed in accordance with ASME A17.1/CSA B44 orapplicable local code, when not conveying passengers.

Almost a decade ago, you were very helpful as we did research for our 2005 White Paper on Opportunities for Elevator Energy Efficiency Improvements., exploring opportunities for programs such as EnergyStar to encourage adoption of advanced technologies and practices. ACEEE has received funding to update and extend this work, with particular emphasis on new policy options. These include first inclusion of elevators in ANSI/ASHRAE/IESNA 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings., EnergyStar, and electric utility incentive programs.
To make our work as robust as possible, we seek to engage the industry itself, those who know best what works, have thought about what could work, and are eager to explore new opportunities. We are not seeking additional funding, but we feel there are other ways Elevator World (and NEil, whom we are also contacting) could help us, for the benefit of the industry you serve. Here are some of our thoughts; and you may recognize other opportunities:
1. We want to form an Advisory Committee of leading manufacturers. We'll ask them individually for their ideas on important available and emerging technologies, and we'll ask them to review our draft report to assure that it meets the highest standards possible. We seek your help in developing contacts at the appropriate firms. We can start with Marketing Directors, or Government Affairs Directors, as long as they have the insights to find the appropriate representatives in their firms. Of course, we'd love to have you on this committee, too.
2. We'd like to provide you with a brief press release announcing the project, for publication as an item in the ELEV ATOR WORLD magazine, or such other distribution as you feel is quickest and works best for you. This assures that we reach industry people.
3. At the conclusion of the project this summer, we'll certainly provide a press release, can develop a blog post (or link to ours), or otherwise help you share our findings with your members.
We would appreciate the opportunity to discuss this with you or your staff this week, Tuesday, or Thursday, if at all possible. Please feel free to respond proactively to reach me.
Sincerely,
Harvey Sachs, Ph.D Senior Fellow, 703-848-8136, hsachs@aceee.org

passenger waits after registering a landing call until the responding elevator door(s) begin to open.
Measured in s at landing from registration of a hall call to responding car door(s) starts to open.
Stopwatch capable of measuring in tenths of a s. Record to nearest tenth.
NOTES: 1. Typically handling capacity is measured over a five minute time period. This is a calculated quantity based on the roundtrip time and passenger loading. The accepted formula for a single car handling capacity is: (Number of passengers up plus down) x 300 s Average round trip time of an elevator = Handling Capacity Group handling capacity is number of cars in a group multiplied by the handling capacity of a single car. 2. Interval is usually expressed as an average time between departures, which is "Loading Interval" and is most meaningful during periods of incoming traffic for a particular building. The interval is often defined as the average roundtrip time of a single elevator divided by the number of elevators in a group. 3. Timing “T” is defined in ADAAG and ICC/ANSI A117.1, as 5 s minimum. See also ADAAG and ICC/ANSI A117.1, for timing requirements when in-car lanterns are provided. 4. The time to destination is a quality of service evaluation consisting of the interval and the time it takes an elevator to travel to the highest indicated call for service. Developed by totaling the lobby dispatch time, the time to make required stops in the up direction and the running time of the elevator in the up direction.
