To reduce energy and operating costs
it is desirable to reduce the size and
volume of mechanical refrigeration.
In housing with renewable energy systems,
it is also practicable to install DC power
refrigerators which are more efficient than
conventional AC powered units.
Much storage for foodstuffs is not directly
temperature dependant, providing that
temperature variation is not large.
In conventional housing, storage is in
light weight cupboards, notably particleboard
or MDF construction offering little thermal
control. Where this is situated on outside walls,
temperature variation can be large.
The result then is to install large refrigerated
storage to hold all meats, vegetable and part
in a storage which has substantially stable
temperatures, some whole vegetables, some
foodstuffs held in air tight containers, can be
held along with general pantry storage.
Such pantry needs to feature:-
In an energy efficient building, this is best
achieved by passive rather than fan operation
- isolation from external temperature variation by being located in the inner of the building
volume, or well insulated from the external building surface
- thermal mass or earth linkage as for a cellar
in part of the pantry construction to assist temperature stability
- deliberate ventilation to enable cool air inflow and stale air extraction.
Such ventilation can include:-
- air inflow vent paths either through the toe-board
and raised floor of the pantry, or direct from the
sub-floor volume under timber floors
- air outflow vents situated in the pantry ceiling or
upper wall to outside, or a high internal space
This outflow can be further encouraged where
there are complementary or interlinked outflow
paths from an adjacent refrigerator or hot water service.
- shelving within the pantry needs to been set away
from the walls with air gap behind.
- The vents should be meshed to be vermin proof.
An integrated layout thus might have the pantry with
its airflow paths situated between:
- a southern subsidence tower providing infeed
as well as general space cooling, and
- the hollow duct in the rear of overhead cupboards
over a refrigerator on the northern side of the
- or air venting away from a hot water service
above the pantry
Such idealised layout is not always possible; and other layouts maximising the pantry potential
are subject to the architect's skill in manipulating the basic principles involved; which
are described in the 'climate response' parts of this web site.
