GrandPalais.fr : Regulation of the temperature in the Nave

Regulation of the temperature in the Nave

Great Staircase: A superb illustration of Art nouveau, the monumental Great Staircase is an instant eye-catcher. Serving as a reception area and the prestigious entrance to the future VIP lounge, it alone illustrates the majesty of the Grand Palais.
Balconies: The fine, understated contour of the balconies that run all the way round the Nave conceals little-known reception and exhibition areas. Only when they have been fully restored will it be possible to access this exceptional viewpoint that takes in the whole of the Nave.
Wolrd time clock: The world time clock has presided over a century of events in the Grand Palais, and, as a work of impressive scale and history, must be restored to its former role in the Nave.
Tympanum: Imagining the interaction and resonance between contemporary creation and heritage. This will be the challenge for the contemporary artist restoring and decorating the tympanum in the Grand Palais.
Corner glass roofs: On either side of the great staircase, the skylight windows in the corners of the building provide warm and intimate reception areas, a welcome counterpoint to the immensity of the Nave. Once restored, these shafts of light will create an even more graphic impact.
Regulation of the temperature in the Nave: Designing a temperature regulation system to operate under the biggest glass roof in Europe, covering a total area of 13,500 m2 (145,000 sq. ft.) for a volume of 450,000 m³ (15,890,000 ft³) is a massive challenge!
Mosaics and glass floors: More than just a restoration, the task of reconstituting the mosaics with their soft colours, and the glass tiles that are so typical of the early 20th century is an invitation to rediscover the sumptuous life and times of the Belle Époque.

Main entrance: It is through the majestic main entrance on Avenue Winston-Churchill that more than one and a half visitors each year enter the Grand Palais.
The pots à feu on the roof and the great sculptures on the pediment: These ornaments and large groups of sculptures make a major contribution to the building's overall impression of splendour: Alfred Picard, commissioner of the 1900 Universal Exhibition, attached particular importance to these curiosities that have since been damaged by the passage of time or simply disappeared.
Illuminations: The design of new illuminations for both inside and outside the Nave is a major and ambitious project for the 21st century and an exciting challenge on the scale of the building itself.

The VIP Lounge: Centrepiece of the restoration project for the Grand Palais, the renovation of the VIP Lounge will enable businesses, patrons and the general public to discover this sumptuous area of 1,200 m2 (12,900 sq. ft.) located in the heart of the building.
The South-East Gallery: A new area with 700 m2 (7,500 sq. ft.) of floor space, the gallery will be able to host events such as exhibitions and fashion shows. Events here will be bathed in outstanding natural vertical light streaming down through the glass overhead.
The Fine Arts Staircase: A jewel in the Grand Palais' crown, the Fine Arts Staircase offers a warm and inviting reception area and an exclusive facility in which to welcome guests. Its discrete atmosphere is enhanced by a staircase that lends a magical sense of elevation as it leads upward to the balconies in the Nave.

A key objective

One of the essential objectives of the Grand Palais' development plans is to ensure optimal comfort for visitors. Currently the heating is a problem in the Nave, if only because of the size of the glass roof and the sheer volume. The transparency of the glass engenders a greenhouse effect in summer and provides insufficient insulation in winter.
Studies are in progress to determine the most suitable technologies for regulating the heat in this unique environment with a volume of 15,890,000 cubic feet. There will be a number of imperatives: as a listed heritage building it requires discrete installations that respect and maintain the clarity and transparency of the Nave; the very nature of the site and the purposes for which it is used call for inventive and modular solutions; environmental considerations mean that only low energy consumption solutions can be envisaged.

Challenge

The installation of a system for regulating the indoor temperature will offer optimal conditions for event organisation and visitor comfort.
The design of the new solution is a challenge, offering the Grand Palais' partner the opportunity to demonstrate and showcase its know-how.
