Provided is a hot melt adhesive for insulating glass spacer, prepared from raw meterials comprising the following components: 1-10 parts by weight of butyl rubber, 25-50 parts by weight of a polyisobutylene mixture; 5-15 parts by weight of a tackifying resin; 1-15 parts by weight of a tackifier; 5-15 parts by weight of a polymer; 0.1-1 part by weight of a lubricant; 0.1-1 part by weight of an antioxidant; 15-50 parts by weight of a filler; 1-10 parts by weight of a water absorbent; and 5-25 parts by weight of carbon black. Compared with the prior art, in the hot melt adhesive for insulating glass spacer provided in the present disclosure, components with specific contents are used, such that relatively good overall interaction is achieved, the thixotropy of the product is good, and the adhesion to both silicone sealant and glass is excellent.

Disclosed is a system of cladding along an existing exterior wall of a building featuring a plurality of Z-shaped components deployed in a parallel spaced apart arrangement, with an insulation panel in between two of the Z-shaped components. The Z-shaped components having a J-wall to enforce a moisture gap between exterior wall paneling and insulation. The Z-shaped components may feature Edge-components when the line of insulation panels needs to be interrupted or when it reaches a corner or edge of a wall.

A structure includes: a heat insulating layer; an evaporator provided on one surface side of the heat insulating layer; a condenser provided on the other surface side of the heat insulating layer; a vapor flow path for guiding refrigerant vapor generated as a result of evaporation at the evaporator to the condenser; and a liquid refrigerant flow path for guiding a liquid refrigerant generated as a result of condensation at the condenser to the evaporator, in which the evaporator has a wick layer for evaporating the refrigerant stored on a lower portion side with heat from one surface side of the evaporator while suctioning up the refrigerant by capillarity and holding the refrigerant, and the evaporator and the condenser are installed so as to overlap by ½ or more in the direction in which the wick layer suctions up the refrigerant.

In some aspects, the present disclosure relates to switchable phase change material system (SPCMS). In some embodiments, dynamic, switchable phase change material systems allow building envelope assemblies to store energy from one side and release to the other side in order to reduce thermal loads and peak demands for both space heating and cooling. PCM layers can be coupled with thermal insulation layers to ensure heat does not transfer readily through the building envelope and thus increase thermal heating and cooling loads for the building. In some embodiments of the present disclosure, a combination of rotatable members comprised of PCM and insulation are switchable in position such that layers with PCM are switched from one side to the other without the need to maintain the thermal insulation within a building envelope.

A facade panel conditioning system for installation on a new or existing building is disclosed. The system includes modular panels, a structural anchor, hydronic piping, and ductwork. The panels attach to each other around the exterior of the building forming an insulated shell. The anchor attaches the panels to the building structure forming an air cavity between each individual panel and the exterior. The hydronic piping transfers heat to the air cavity and individual units of the building. The ductwork delivers ventilated air and exhaust air to the air cavity and individual units. The hydronic piping of a panel connects to the hydronic piping of an adjacent panel forming a hydronic piping system that distributes heat or cool throughout the shell. The air duct of a panel connects to the air duct of an adjacent panel forming an air duct ventilation system that distributes air throughout the shell.

Systems and methods are provided and include a variable frequency drive configured to drive a fan motor of an HVAC system to ventilate an indoor space, the HVAC system having a cooling assembly that includes at least one of an economizer and a compressor. A controller is configured to communicate with the variable frequency drive, receive at least one signal from an occupancy sensing device, determine whether the indoor space is less than fully occupied based on the at least one signal, and control the variable frequency drive to reduce a speed of the fan motor in response to determining that the indoor space is less than fully occupied.

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.

A device for climate control of a building (20), in which flatly formed external temperature elements (5) at least partially cover an outer side of the building (20), wherein the external temperature-control elements (5) are settable to a predefinable temperature value. Furthermore, a temperature-control element (5) and a method for climate control of a building (20) are specified.
