Appreciation towards Výstaviště Praha for providing the following description:

Křižík展馆由建筑师Michal Brix设计，于1991年建成，旨在纪念1891年千禧年博览会一百周年。展馆与Křižík喷泉共同构成工业宫北侧前广场的重要组成部分，突出了整个园区的中轴线布局。建筑巧妙地利用了地势高差，使工业宫殿成为具有视觉冲击力的背景。尽管展馆最初是为1991年捷克斯洛伐克全国博览会而设的临时建筑，但一直沿用至今。

The Křižík Pavilions, built in 1991 according to a design by architect Michal Brix, were built on the occasion of the centenary of the Provincial Jubilee Exhibition (1891). Together with the Křižík Fountain, they form an important part of the northern foreground of the industrial palace and highlight the compositional axis of the entire complex. The pavilions take advantage of the sloping terrain and place the Industrial Palace as a strong background motif. Originally intended as temporary structures for the 1991 General Czechoslovak Exhibition, they have been used to the present day.

历经三十余年的高强度使用后，展馆已难以满足现代展览的空间需求。因此，此次改造不仅旨在对建筑进行技术升级，更赋予其新的功能定位，以适应展览、博览会、音乐会以及电视录制等多样化用途。

After more than thirty years of intensive use, the pavilions no longer meet the current requirements for exhibition space. The aim of the revitalization was therefore not only to modernize the buildings technically, but also to give them a new functionality that would cover a wide range of uses. From exhibitions and fairs to concerts and television filming.

展馆内部空间经历了显著转变。展厅采用哑光黑色涂装，使展品更具视觉突出感；技术与卫生设施则使用浅色调，增强空间的导向性。混凝土结构在室内保持原始质感，与不锈钢栏杆、扶手和家具等元素共同营造出工业风格，强化了建筑的设计理念与空间特质。

The interior of the pavilions has undergone a significant transformation. The interior of the exhibition pavilions has been given a black matt paint finish, allowing the exhibits to stand out. The technical and sanitary facilities are designed in light tones for better orientation. The concrete structures in the interior are left in their raw form and, together with stainless steel elements such as railings, handrails and furnishings, reinforce the industrial character of the space and the building’s design principles.

此次改造的核心亮点之一是屋顶的全面更新。原本废弃、未被利用的混凝土屋面被改造成对公众开放的绿色活动屋顶。这一设计回应了当下对城市可持续发展的关注，不仅能缓解热岛效应，也改善了雨水的径流管理。同时，该屋顶也成为一个功能多元的开放空间，可全年使用。除绿地休憩外，还设置了简餐服务区、跑道和游乐设施，转化为集休闲、运动、社交于一体的多功能场所。

One of the key elements of the revitalization is the roof, which has been given a completely new character. Originally unused and neglected fully concrete areas have been transformed into active green roofs accessible to the public. This green roof concept responds to the current need for sustainable urban interventions that reduce the heat island effect and improve the runoff balance of rainwater. At the same time, we are creating a space with a diverse function, allowing for year-round use. In addition to rest and relaxation in the green space, we want to enable simple dining as well as sports and social activities. The roof now houses a cafeteria, a running track and play elements that turn the space into a multifunctional place.

改造前，屋顶全部由深色混凝土铺装构成，在白天吸收大量热量，形成“热岛效应”，使周边温度升高1至3摄氏度（夜间甚至可达10摄氏度）。此次改造共减少了约5000平方米的混凝土面积。屋顶种植的密集型绿色植被有效减缓了空气与尘埃流动，带来更加宜人的局部气候。植被不仅能够释放氧气，还能提高空气湿度，进一步改善空气质量。全新的屋顶结构结合了蓄水层、绿植区与可行走铺面，每年可减少约1000立方米雨水直接排入市政排水系统。这部分雨水被储存在绿色层中，用于植物生长和自然蒸发。

Originally, the entire roof surface was made up of dark concrete paving, which absorbed a huge amount of heat during the day, creating a “heat island” effect, raising the temperature of the surrounding area by 1–3°C (in the evening it can be up to 10°C). The total concrete area was reduced by about 5000 m2. The intensive vegetation planted on the roof slows down the movement of air and dust, resulting in a significantly more pleasant local climate. In addition to oxygenating the air, the greenery also increases the humidity of the air, thus positively influencing its quality. The new layering of the service roof (combination of green intensive roof with accumulation layer and walking surfaces) reduces the amount of storm water discharged to the site sewer by about 1000 m³/year. This amount remains accumulated in the green roof layer during rainfall and is subsequently used for green growth and evaporation from vegetated areas.

Křižík展馆的更新不仅延续了历史文脉，更以当代建筑语言回应了城市发展的新需求，为布拉格市中心提供了一个高品质的多功能使用空间。

The revitalization of the Křižík Pavilions thus represents a combination of history and modern architecture that responds to the current needs of urban space and offers a high-quality multifunctional use in the heart of Prague.
