The character and function of a lobby space often influence a visitor's first impression upon entering a building. Key design concerns for this space type include balancing aesthetics, security, sustainability, and operational considerations. Typical features of lobby space types include the list of applicable design objectives elements as outlined below. For a complete list and definitions of the design objectives within the context of whole building design, click on the titles below.
Accessibility should be planned early in the process. Various types of disabilities should be considered, including those with visual, learning, mobility, speech, and hearing impairments. Staff should also be educated and informed regarding how to provide an appropriate service or accommodation that might be requested or required.
Physical features to address in the lobby space include:
星辰棋牌官网Utilize appropriate finishes, furniture, signage, and art to reflect the public nature of the space as well as the image of the organization(s) housed within the building.
A spatial compression/release experience can enhance the aesthetic experience (outside approach, compression thru entrance doors/vestibule, release in lobby/atrium).
Public buildings will often have historic features in lobbies and hallways, requiring—and deserving—special design treatment in renovations.
Maintain the historic character of spaces while modernizing for enhanced security, accessibility, sustainability, and general circulation.
Lobby spaces requiring 24-hour operation should be provided with a dedicated HVAC system.
For lobby spaces at the exterior of a building, a dedicated air-handling unit should be provided to maintain positive pressurization.
星辰棋牌官网Design lobbies to provide workers/occupants with a relief opportunity—such as breaks—from more confined spaces. Whenever possible, incorporate views to nature or incorporate elements such as a water feature, plants, and natural materials.
星辰棋牌官网In higher-risk facilities, separate secure and non-secure areas with turnstiles, metal detectors, or other devices used to control access to secure areas. A control desk and bag checking area should be located within the secure area. Mechanical ductwork, piping, and main electrical conduit runs should not extend from one area to the other. Traffic separation devices should be flexible and portable to allow for changing traffic patterns.
星辰棋牌官网Design control points such that secure areas cannot be bypassed. Ensure that security personnel can properly observe all areas of control points.
星辰棋牌官网Larger security screening areas should be located in conjunction with art installations, visitor seating, and exterior entrances. Adequate space should be set aside for queuing. If queuing will occur, the area should be enclosed in blast resistant construction.
Avoid installing features such as trash receptacles or mailboxes that can be used to hide devices in non-secure areas.
Avoid using raised floor systems in non-secure areas.
星辰棋牌官网Location of fire command center and emergency elevator control panel requires design integration with lobby wall finishes, BAS systems, fire protection systems, and building communications systems.
星辰棋牌官网Design of lobby doors to the street(s) must account for egress from higher floors if stairs exit into lobby, and not directly to the outside.
星辰棋牌官网Designing a sustainable lobby space should be part of an integrated process that takes into account: the materials, operations, and health and well-being of the users.
For lobby spaces at the exterior of a building, utilize daylightingthrough the appropriate placement of windows and skylights to reduce electric lighting needs Utilize features such as shading devices to decrease direct solar gain. (For more information, see Energy-Efficient Lighting, Daylighting, and Windows and Glazing.)
Provide insulation in roofs and walls in order to reduce energy use and heat gain in the space.
星辰棋牌官网Incorporate natural ventilation to lower utility costs.
Address healthy indoor environmental quality星辰棋牌官网 through appropriate airflow and filtering of air. Use low-emitting materials, furnishings, and finishes that do not off-gas.
星辰棋牌官网Use durable products in the lobby space and plan for products with reduced packaging and recyclability potential to minimize waste.
The following agencies and organizations have developed codes and standards affecting the design of lobbies. Note that the codes and standards are minimum requirements. Architects, engineers, and consultants should consider exceeding the applicable requirements whenever possible:
Accessible—Provide Equal Access and Flexibility, Aesthetics—Understanding the Language and Elements of Design, Functional / Operational—Account for Functional Needs, Functional / Operational—Ensure Appropriate Product/Systems Integration, Productive—Assure Reliable Systems and Spaces, Productive—Provide Comfortable Environments, Secure / Safe—Occupant Safety and Health
