SPECIAL NOTICE F19SN010001-EE

I. DWRC Lighting Renovation Special Notice

SI Lighting Design Team: Alexander Cooper (NPG), Scott Rosenfeld (SAAM)

Design Manager: Greg Bacani (OPDC)

Supervisory Architect: Tim Buehner (OPDC)

II. General Project Scope:

1. Remove and Replace all existing track components and track lighting fixtures in the Donald W.

Reynolds Center of American Art and Portraiture (DWRC). Use the 2017 America’s President’s lighting renovation project as the basis of design for all new track and fixture specifications.

2. Develop and implement an architectural lighting control software solution and hardware infrastructure capable of supporting the new track lighting system according to design criteria for architectural lighting control. Use the 2017 America’s President’s lighting renovation project as the basis of design for all new lighting control system specifications.

3. Installation of all lighting track, and control equipment by SI self-directed workforce

III. America’s Presidents Pilot Project:

In August 2017 the NPG re-opened the America’s Presidents (AP) Gallery in the DWRC 2West-

South and 2 South-West galleries. Designing, installing the new lighting, and lighting control system was a significant part of the gallery renovation. This new lighting system was conceived as a pilot project for future lighting renovation efforts in the DWRC . The design requirements for the AP lighting renovation project are described in the document

“AP_Lighting_Requirements.pdf”

The aesthetic performance of the lighting pilot is considered a success by the NPG lighting designer as well as the NPG Director and senior staff. The design involves LED sources and wireless communication technology, both of which are relatively new to the market. For that reason, the NPG exhibit technology department (EX-IT) has monitored and documented the performance and reliability of the pilot lighting system for 12 months following the opening of the gallery. Our initial observations are documented in “LSI Fixture Log.xlsx”. In spite of minor software anomalies, we found the technology to be reasonably durable. It is our recommendation that this control strategy in expanded throughout the DWRC.

IV. Primary Condition: Lighting fixtures and lighting track installed onto historic masonry or historic fabric.

Requirements:

The following describe requirements the Light System Manufacturer (LSM) must meet to qualify for selection for the primary condition. The primary condition encompasses all lighting equipment installed in public spaces with a historic masonry ceiling.

Lighting fixtures, lighting components and lighting track must form a complete interoperable system. Since lighting components from one manufacturer are not generally compatible with components from another, a Lighting System Manufacturer (LSM) was selected using the requirements listed below. Specific lighting components (track, fittings, fixtures) were then selected from that manufacturer’s catalog according to individual, or multiple requirements listed below.

1. In order to provide track capable of installation in the barrel-vaulted ceiling of the Donald W.

Reynolds Center (DWRC) the lighting system manufacturer must provide light track capable of factory bends up to a 10’-0” radius1. Any manufacturers of track systems unable to be bent, or incapable of being bent to a minimum 10’-0” radius cannot be included for consideration for this project.

2. In order to minimize the risk of mechanical and electrical failure at track lighting feed and joiner connections the lighting system manufacturer must provide light track capable of a secure attachment to a historic masonry structure2. A secure attachment is defined in terms of track rigidity and surface area of contact with plenum. Any manufacturers who cannot provide lighting track systems with an extrusion height greater than 1.5” and an extrusion width greater than 1.5” will not be considered rigid enough to ensure a secure attachment to historic masonry structure, and cannot be included for consideration for this project.

3. In order to minimize the risk of electrical failure at track lighting feed and joiner connections the lighting system manufacturer must provide light track with an over-sized neutral bus-bar

1 Lighting track needs to be bent to fit the curves of the Old Patent Office’s historic barrel vaults; the requirement for this application is that track shall be available a maximum radius of 30 feet and a minimum radius of 8.5 feet. In addition to lighting track having the capacity to bend, the lighting fixtures track adapter shall securely fit into bent track with radius as small as 8.5 feet.

2 The existing lighting track catastrophically failed because it wasn’t securely attached to the structure. Lighting track shall meet the following criteria in order to insure secure attachment to the historic masonry in the Old Patent Office (DWRC).

Surface mounted lighting track shall be sufficiently large to maximize rigidity. Surface mounted lighting track shall attach directly to the ceiling, without clips to insure more surface contact with surface and ensure a strong connect, and be attached using ¼” diameter expansion anchors, for strength and security into historic masonry. Additionally, the head of the screw shall be embedded completely into extrusion without interfering with the installation of lighting fixtures directly below attachment point, this is necessary because protruding screws make those portions of the track unusable.

comparable to #10 American Wire Gauge (AWG)3. Any manufacturers of light track with a neutral bus comparable to greater than #10 AWG wire cannot be included for consideration from this project.

4. In order to provide track lighting fixtures capable of object lighting works of fine art the lighting system manufacturer must provide light fixtures with an LED source capable of a minimum 4 degree beam-angle distribution4. Any manufacturers of track lights with an LED source not capable of a minimum 4 degree distribution cannot be included for consideration for this project.

5. In order to provide track lighting fixtures capable of lighting architectural spaces and features to the high aesthetic demands of a national arts institution the lighting system manufacturer must provide light fixtures capable of changing color and produce a beam angle distribution between 16 and 50 degrees5. Any manufacturers who cannot provide fixtures capable of color changing and beam angle distributions between 16 and 50 degrees cannot be included for consideration for this project.

6. In order to provide granular control of individual fixtures in a historic building the lighting system manufacturer must provide light fixtures capable of wireless, bi-directional control and status monitoring of all fixture attributes. Any manufacturers who cannot provide light fixtures capable of bi-directional, wireless communication cannot be included for consideration for this project.

7. In order to increase inter-operability with third part control systems sued in the DWRC the lighting system manufacturer must provide light fixtures that utilize an open-source Application Protocol Interface (A.P.I.) for communication with an architectural control system. Any manufacturers who cannot provide fixtures that communicate to third part control systems with open-source API’s cannot be included for consideration for this project.

3 The neutral busbar shall be oversized to be comparable to #10 gauge 30 amp wire to reduce the possibility of electrical problems including overheating due to non-linear loads and harmonics.

4 Lighting manufacturer shall furnish fixtures capable of producing narrow beams of light with a maximum beam spread of 4-degees required to light small art objects.

5 Lighting manufacture shall furnish fixtures capable of producing light that can change in color and produce a beam spread of between 20 and 60 degrees; this range of beams is necessary to evenly cover wall with light. Fixtures shall be able to maintain their color point to within 2 noticeable differences (McAdam’s ellipses in CIE1931 color space) and be capable of producing light with a color rendering index (CRI) of 90 or higher; these criteria are necessary to insure proper color and spectral characteristics for works of fine art.

LSM Evaluation and Selection:

Over the course of the past 12 months (January 2018 - January 2019) the SI Design Team evaluated track fixtures and track components according to the requirements listed above.

Below is the market research for essential criterial for lighting track and track lighting fixtures for the

DWRC. Research was conducted via internet searches and by visiting international trade shows searching for alternatives including but were not limited to: Lightfair International 2018 in Chicago, LEDeducation 2018 in NYC, The Museum Lighting Conference in London 2017, and the Department of Energy R&D conference 2017.

Five Lighting System Manufacturers were included in the evaluation using the seven requirements listed above as selection criteria. The LSM’s were: Lighting Services Inc. (LSI), Edison Price Lighting, Electronic Theatre Controls (ETC), Litelab Corporation, and Lightoliere. Our research found LSI to be the best choice of LSM for the primary condition.

V. Secondary Condition: Lighting Track installed in Existing Recessed Housings

The following describe requirements a Light System Manufacturer (LSM) must meet to qualify for selection for the Secondary Condition: Lighting Track Installed in Existing Recessed Housings in portions of the building including: Luce Center, the Café and Museum Shop. The advantage of reusing existing recessed housing it reduces risk to museum collections because artworks may remain in place in and reduces the impact on store and café operations because installation is significantly faster. Due of existing conditions in the Luce Center, Café and Museum Shops, lighting track provided by the LSM that meets the secondary condition requirements may not be surface mounted.

1. In order to reduce the risk of damage to museum collections in the Luce Center and reduce the disruption to museum shops and café operations the lighting system manufacturer (LSM) must provide light track capable of installation within existing recessed track housing originally manufactured by Zumbtobel. To comply with this requirement, lighting track extrusion must be exactly 1 5/32” wide and not exceed shall not exceed 7/8” in height6. Any manufacturers of lighting track that does not have an extrusion dimension of 1-5/32” wide and less than 7/8” in height cannot be included for consideration for this project.

LSM Evaluation and Selection:

Over the course of the past 12 months (January 2018 - January 2019) the SI Design Team evaluated track fixtures and track components according to the requirements listed above.

Below is the market research for essential criterial for lighting track and track lighting fixtures for the

DWRC.

Five Lighting System Manufacturers were included in the evaluation using the seven requirements listed above as selection criteria. The LSM’s were: Lighting Services Inc. (LSI), Edison Price Lighting, Electronic Theatre Controls (ETC), Litelab Corporation, and Lightolier. Our research found Lightolier to be the best choice of LSM for the secondary condition.

6 While the existing track made by Zumbtobel is deficient and needs to be removed, there are areas that contain recessed track where the existing track housing can be reused. Reusing the existing housing is essential to the project to save time and money, but most importantly reusing the existing housing will allow new lighting track to be installed without de-installing artwork adjacent to the lighting track. The existing housing is 1 5/32” wide and Lightolier is the sole source of lighting track that matches this dimension.

Subject: American Presidents Lighitng

Hi Tibor, Beginning 6 months ago I began an in-depth evaluation of LED-based light fixtures in anticipation of the America’s presidents re-conception. There were 7 main evaluation criteria:

1. High Color Rendering – Suitable for works of fine art.

2. Sophisticated Optical Systems - Capable of arbitrary beam distributions and beam shaping

3. Mechanically reliable - Provide a solution to our current problems of fixture, track, and electrical failure widely evident throughout the museum.

4. Photometrically Reliable – The Light Quality must remain consistent for a significant period of time (10+ years)

5. Forward thinking technology – a solution that will remain at the forefront of the wave of technology for at least 10 years.

6. Energy efficient - provide significant “Green” advantages to the museum in terms of electrical usage, HVAC usage, maintenance staffing requirement.

7. Visually Appealing – The appearance of the fixture/track system must be appropriate for a historic building and a fine art museum.

After some initial research I selected three manufacturers for consideration: Lighting Services Inc (LSI), Erco Lighting, and

Ketra Lighting. We purchased mock-up systems from LSI and Ketra this Summer and began a “burn-test” using the

Herbert Hoover Portrait to rate our findings against the project criteria. We were unable to acquire Erco products due to administrative challenges (they are a European-based company, long story). Erco fixtures also had a very unusual look, which made them an outlier from the beginning. I was comfortable focusing on the other two manufacturers.

After an evaluation over the Summer my recommendation is to pursue a multi-source solution for America’s

Presidents. The first part of the solution is the LSI 2044 remote phosphor LED fixture, which provides exceptional distribution and color rendering, and LSI can also manufacture a very precise 4 degree object light that is a beautiful complement to the remote phosphor. LSI fixtures also have a built in blue-tooth transceiver, which not only allows for remote control and dimming of the fixtures in the gallery, but also established a Bluetooth mesh in the space that can be leveraged for future technology-based initiatives. The LSI solution satisfies all 7 project criteria. In addition, LSI also manufactures a small form factor version of the 2044 that could be an excellent replacement for our ageing track lighting system on the first floor, should we ever consider extending this project to our other spaces.

The second part of the solution is to invest in Keta color Changing LED lamps, which we would install in LSI fixtures. The

Ketra system also operates on a Bluetooth mesh control system, and it provides color changing functionality, which opens the door to all kinds of design possibilities we have been unable to explore in the past. This was a surprise to me

Erricksone Typewriter AP Lighting Requirements as color changing technology has traditionally been rather course and unrefined, good for simple bold color choices

(parties, etc..), but not suitable for museums. With Ketra we see a change to that, one that could enliven the America’s

President’s galleries dramatically.
