The major benefit is that the ventilation systems and their duct work need only about 20% of the space requirements of conventional HVAC systems, reducing cost. Currently research is done to a explore the opportunities of bining the radiant cooling/heating piping with the sprinkler system which might reduce the initial cost (due to reduced floor height and savings in pipe grids) even further. Because of the hydronic energy transport, this cooling system has a potential to interact with thermal energy storage systems and looped heat pump systems. Hydronic radiant cooling has been applied in the ., but it never reached significant market peration. Together with efficient ventilation systems and humidity control, the hydronic radiant cooling system provides advantages over conventional HVAC systems that are worth considering during building design. The Brose Integrated Hydronic Design What appears to be today?s stateofthe art heating and cooling system technology was in fact used in largescale applications in the . as early as 1960. A highrise office building located at the west bank of Lake Merrit in downtown Oakland for example used a radiant hydronic cooling system for is 28 story office floors. Surprisingly, the specific cooling energy (W/m2) of the office building is significantly larger than that of buildings of parable size located in downtown San Francisco using a mon forced air airconditioning system. The building has approximately 60% of its 100,000 m2 ceiling area equipped with radiant cooling panels, and it is expected that these systems require less cooling energy for operation than AllAir Systems that provide the same cooling effect. Our project for Brose will investigate and analyze all systems, such as air supply, envelope and glazing systems, return air, and radiant cooling/heating with their interdependencies and will use significantly less energy as a conventionally airconditioned office building. The optimized systems and the hydronic concept will thus provide a healthier indoor environment than AllAir Systems. Air Distribution The key to the understanding of the integration of the Brose building system is the partial separation of the heating and cooling function from the ventilation requirements of the new facility. Since heating and cooling are largely provided by the thermal mass with its embedded hydronic system, the ventilation infrastructure can bee significantly smaller. The supply air for the new facility will be entering the occupied spaces through an access floor system, which is raised 0,30 m above the structural slab. Supply air diffuser placement is flexible, and can be changed according to the requirements of the workstation layout. Supply air enters the occupied zones at a reduced velocity of m/s as displacement ventilation. As with hydronic cooling systems, displacement ventilation has been used in Northern Europe in theaters, office buildings, restaurants and auditoriums for at least twenty years in all applications where contaminants are not heavier than air. Special attention has to be placed on temperature in order to avoid disfort in the supplied and occupied zone. Indoor air quality is improved so is energy efficiency. The pressurized access floor in the Brose building will omit ducts。項(xiàng)目登 記 為 LEED?建筑 設(shè)計(jì)。這個(gè)戰(zhàn)略節(jié)省能量和創(chuàng)造優(yōu)越內(nèi)部氣候?yàn)榫幼≌叨也粌H顯示 系統(tǒng)認(rèn)為和關(guān)鍵和先進(jìn)的技術(shù)解答的早期的綜合化新方式入非常早期設(shè)計(jì)階段。我提議 為 熔化所有四藝術(shù) 、為 他們的團(tuán)結(jié)一起干杯 ！ 歷史上 液體循環(huán) 輻射 制熱的 大廈系統(tǒng) 從羅馬帝國的最早期的結(jié)構(gòu) 的 能 利 用的地板面積之下 發(fā)現(xiàn)了 熱量迷宮、洞和渠道。在最新羅馬設(shè)計(jì) , 控制 氣流 時(shí)更多的介紹使用赤陶土 管子。對(duì)同樣管道系統(tǒng)的用途 , 典型地 由
