We claim: 1. A unitary stackable energy transfer core spacer comprising a peripheral frame member, said peripheral frame member extending about and defining a framed core opening, said peripheral frame member having a pair of opposed major sides, said peripheral frame member comprising a pair of side opening components and a pair of side wall components, each side opening component comprising a framed side opening in air communication with said framed core opening, each side wall component respectively interconnecting said side opening components, said spacer being configured such that said spacer may be oriented and stacked, major side to major side, on top of a second like spacer, with an intermediate air to air energy transfer sheet extending across the framed core openings and being sandwiched between the frame members of both spacers so that the spacers and the energy transfer sheet define a pair of transversely oriented air paths on opposite sides of the energy transfer sheet, each air path extending from one respective framed side opening through a respective framed core opening to the other respective framed side opening of a respective spacer and wherein each side opening component comprises a first frame element and a second frame element, said first frame element and said second frame element being associated with a respective major side of the frame member, being spaced apart by a respective framed side opening and being offset with respect to each other such that one frame element does not overly the other frame element. 2. A stackable energy transfer core spacer as defined in claim 1 wherein peripheral frame member, said on each major side thereof, comprises an inter-registrable tongue/mortise interlock elements. 3. A stackable energy transfer core spacer as defined in claim 2 wherein said first frame element and said second frame element, of each side opening component, each define an inter-registrable tongue/mortise interlock element, wherein each side wall component defines a pair of offset inter-registrable tongue/mortise interlock elements, and wherein each interlock element of a side wall component is associated with a respective major side of the frame member and configured to be able to register with a predetermined tongue/mortise interlock element of a frame element of the frame member of said second like spacer so as to define a pair of interlocked elements. 4. A stackable heat transfer core spacer as defined in claim 1 having a hexagonal like configuration. 5. A stackable heat transfer core spacer as defined in claim 3 having a hexagonal like configuration and wherein each side wall component comprises a first side wall element and a second side wall element, said side opening components and said first and second wall elements being configured and disposed so as to provide the frame member with an hexagonal like shape, wherein a side opening component is connected to one side wall component by the first side wall element thereof and to the other side wall component by the second side wall component thereof, wherein each first side wall element defines a pair of offset inter-registrable tongue/mortise interlocks elements of said side wall component, and wherein each second side wall element defining a pair of aligned inter-registrable tongue/mortise interlock elements. 6. A stackable energy transfer core spacer as defined in claim 5 wherein the spacer comprises one or more rib air guide elements disposed in the framed core opening, said rib air guide elements being connected to the frame member. 7. A stackable energy transfer core spacer as defined in claim 6 wherein one or more of said rib air guide elements extend from one said framed side opening to the other framed side opening. 8. An air to air energy recovery core having a first air path and a separate second air path, each air path having a respective air inlet and a respective air outlet, said core comprising a stack of one or more successive heat transfer stages, each such stage comprising an energy transfer sheet having opposed major faces and a pair of spacers engaging opposite major faces of the sheet, each of said spacers being a spacer as defined in claim 1, said spacers being oriented and disposed relative to each other so that the spacers and the energy transfer sheet define a pair of transversely oriented air paths on opposite sides of the energy transfer sheet, each air path extending from one respective framed side opening through a respective framed core opening to the other respective framed side opening of a respective spacer, the framed side openings of one frame member each respectively defining a respective element of the air inlet and air outlet of the first air path and the framed side openings of the other frame member each respectively defining a respective element of the air inlet and air outlet of the second air path. 9. An air to air energy recovery core having a first air path and a separate second air path, each air path having a respective air inlet and a respective air outlet, said core comprising a stack of one or more successive heat transfer stages, each such stage comprising an energy transfer sheet having opposed major faces and a pair of spacers engaging opposite major faces of the sheet, each of said spacers being a spacer as defined in claim 7, said spacers being oriented and disposed relative to each other so that the spacers and the energy transfer sheet define a pair of transversely oriented air paths on opposite sides of the energy transfer sheet, each air path extending from one respective framed side opening through a respective framed core opening to the other respective framed side opening of a respective spacer, the framed side openings of one frame member each respectively defining a respective element of the air inlet and air outlet of the first air path and the framed side openings of the other frame member each respectively defining a respective element of the air inlet and air outlet of the second air path.
