摘要:
An energy-reducing method and apparatus for retrofitting a single zone, constant volume HVAC system, with or without an economizer, that provides heating, cooling, and ventilation to occupants within a building space. The present invention includes the introduction of a programmable logic controller and variable frequency drive (VFD) that takes control of the existing fan, heating, cooling, and optional economizer operation. The reduction of the fan speed in the ventilation mode when the 100% operation is not needed saves significant energy of the existing constant volume HVAC system where the fan motor is designed to run 100% of the time.

An anchor for securing together interior and exterior building components includes a first end having an outer side for engaging the interior building component and an inner side opposite the outer side. The anchor further includes a second end having an outer side and an inner side opposite the outer side of the second end for engaging the exterior building component. A thermal break for reducing thermal bridging between the exterior and interior building components is disposed in a space between the inner sides of the ends and has a first coupling surface bonded to the inner side of the first end and a second coupling surface bonded to the inner side of the second end. An assembly includes the anchor for securing together the interior and exterior building components.

The present disclosure relates to a thermal break for use in tilt-up construction. The thermal break generally comprises an elongate body comprising a thermal insulating material. The thermal break may further comprise one or more protrusions extending away from the elongate body. The present disclosure further relates to a method of constructing an exterior wall comprising the thermal break positioned between a fascia wythe and a structural wythe of the exterior wall. The exterior wall may be tilted up to a vertical position during construction of a building, and the thermal break provides a fixture-mounting surface onto which a fixture, for example a door frame, window frame, air venting grill, or other building component can be mounted.

An insulating panel structure has an inner surface for attachment to a building exterior and an outer surface for attachment to cladding material. The panel structure has external stringers for attachment of the cladding, connectors extending perpendicularly from the inner surface to the external stringers to transmit compressive forces from the cladding to the building, lateral connectors that run diagonally upward from the external stringers to the inner surface to transmit tensile forces from the weight of the cladding to the building, and insulating foam embedded between the panel inner and outer surfaces. A panel application method includes providing panels with tubular connectors and providing expansible fingers insertable into the tubular connectors and mounted on a movable frame, inserting the fingers into the tubular connectors, expanding them to grip the tubes and panels, moving the frame with expanded fingers and panel to a job site, attaching the panel to a building while being held with the expanded fingers, and contracting and retracting the fingers from the attached panel.

Premanufactured structures for constructing buildings comprise a construction system for an energy efficient multi-story building with standard single or mixed units. The multi-story building is constructed using premanufactured structures: non-weight bearing walls with finished exterior including all electrical, insulating, plumbing and communications components that are premanufactured at a site distant from a building site, and the non-weight bearings walls are attached to a floor and ceiling slabs, interfacing with each other to enclose units of the building; interior components that are premanufactured at a remote site to connect to inside portions of the non-weight bearing walls; and exterior components that are premanufactured at the remote site to attach to exterior surfaces of the building. Non-weight bearing walls, interior components, and exterior components are installed and connected together to provide the energy efficient multi-story building with units with different floor plans, and optionally, a retail level with underground parking.

A low-emittance material having improved energy efficiency protection against air infiltration and moisture build-up in buildings is disclosed. The aforementioned low-emittance material utilizes existing framing openings or without increasing the wall profile of a building. The present invention provides a low-emittance material which may be implemented on traditional 2×4 framing having R-15 mass insulation material within existing or newly constructed framing cavities. The material of the present invention also meets requirements for serving as a water resistive barrier as defined by ICC AC38.
