Intent

• Reduce the waste that is generated by building occupants and hauled to and disposed of in landfills.


Requirements

• Provide dedicated areas accessible to waste haulers and building occupants for the collection and storage of recyclable materials for the entire building.

• Collection and storage areas may be in separate locations.

• Recyclable materials must include mixed paper, corrugated cardboard, glass, plastics, and metals.

• Take appropriate measures for the safe collection, storage, and disposal of two of the following:• Batteries, • Mercury-containing lamps• Electronic waste.


• Conduct a waste stream study to identify the retail project’s top five recyclable waste streams, for 24 Hrs.

• Provide storage and collection space for top four waste streams• If no information is available on waste streams for the project, use

data from similar operations to make projections.• Retailers with existing stores of similar size and function can use

historical information from their other locations.• Provide dedicated areas accessible to waste haulers and building

occupants for the separation, collection, and storage of recyclable materials.

MR C9 Design for Flexibility

Design

Healthcare Only

1


Intent

• Conserve resources associated with the construction and management of buildings by designing for flexibility and ease of future adaptation and for the service life of components and assemblies.


Requirements• Increase building flexibility and ease of adaptive use

over the life of the structure by employing at least three of the following strategies.

• Interstitial space• Program soft space• Shell space• Horizontal expansion capacity• Future parking• Demountable partitions• Movable/modular casework


Interstitial Space• Design distribution zone utility systems and equipment including

HVAC, plumbing, electrical, information technology, medical gases, and life safety systems to serve the occupied zones and have the capacity to control multiple zones in clinical spaces.


Programmed soft spaces• Provide programmed soft space, such as administration or storage,

equal to at least 5% of departmental gross area (DGA). Locate soft space adjacent to clinical departments that anticipate growth. Determine a strategy for future accommodation of displaced soft space.


Shell Spaces• Provide shell space equal to at least 5% of DGA. Locate it such that

it can be occupied without displacing occupied space.• Shell space is an area designed to be fitted out for future expansion.

It is enclosed by the building envelope but otherwise left unfinished; it may not be climate controlled or illuminated, but adding these utilities would not disrupt hospital functions.


Horizontal expansion• Identify horizontal expansion capacity for diagnostic and treatment

or other clinical space equal to at least 30% of existing floor area (excluding inpatient units) without demolition of occupied space (other than at the connection point). Reconfiguration of additional existing occupied space that has been constructed with demountable partition systems is permitted.


Vertical Expansion• Design for future vertical expansion on at least 75% of the roof,

ensuring that existing operations and service systems can continue at or near capacity during the expansion.


Future above grade parking• Designate space for future above-grade parking structures equal to

50% of existing on-grade parking capacity, with direct access to the main hospital lobby or circulation. Vertical transportation pathways that lead directly to the main hospital lobby or circulation are acceptable.


Demountable Partitions• Use demountable partitions for 50% of applicable areas.• Demountable partition is a temporary interior wall that can be

easily reconfigured. In a health care facility, acoustical concerns and embedded equipment, as in a surgery suite, may prevent demountable partitions from being used


Modular casework• Use movable or modular casework for at least 50% of casework and

custom millwork. Base the calculation on the combined value of casework and millwork, as determined by the cost estimator or contractor.

• Modular and movable casework shelving and cabinetry designed to be easily installed, moved, or reconfigured.
