Energy performance in hotel construction
Managing energy performance in hotel
construction
Because a building’s architecture, design and construction play
a vital role in reducing its environmental footprint, more and
more countries are defining construction standards that improve
a building’s energy performance and minimize its impact on
surrounding ecosystems.As a professional hotel builder,Accor
has acquired extensive environmental engineering expertise.
It regularly tightens its standards and conducts pilot projects
to design hotels that are ever more efficient in using energy,
water and potentially harmful chemicals and materials.
Following on from the guidelines released in 2008, an internal
standard listing all of Accor’s international guidelines for
hotel
construction and refurbishment
was published in 2013. It covers
a wide variety of issues that must be addressed when building
or refurbishing a hotel:
ƒƒ
general principles for integration into the local environment and
architecture:
compliance with applicable legislation and standards;
producer and supplier compliance with applicable Charter 21 rules
and recommendations; recommendations for the deployment of
a certification process;
ƒƒ
energy:
architecture adapted to the local climate (appropriate
orientation of buildings, location and sizing of windows or other
glazed areas, sun screens, natural lighting, etc.) and optimized
passive energy systems (high-performance thermal insulation,
reduction of thermal bridges, lobbies to external doors);
