西班牙帕倫西亞　221-DH PALENCIA再生能源熱電廠

本項目為能源領先企業 DH Ecoenergías 所推廣的首座區域供熱電廠，是西班牙城市能源轉型的先鋒。該計畫旨於將再生資源取代成本高昂的進口化石燃料（柴油和天然氣），以自然生物質能轉化為熱能，再輸送至各建築物中以實現城市去碳化。該中央供熱系統除了須具備能源生產的技術外，亦須兼具業主所期望達到的教育傳達功能――一座幫助環境轉型的標竿性建築，同時象徵著再生能源、創新模板以及城市公共衛生的改善與進步。因此團隊不僅將其作為純粹的功能性量體設計，更深度思考該建築所將傳達的意義層面。

This small building is the visible part of a whole that remains hidden from view. It is the head of a new energy infrastructure for the city of Palencia. A District Heating network promoted by the company DH Ecoenergías, a brave pioneer in the energy transformation of Spanish cities. Palencia's network is the first of a long series of similar projects that seeks to decarbonize a good part of the national urban geography, turning off fossil fuel heaters diesel and gas, costly internationally sourced to replace them with a clean network, fueled by renewable resources that will largely come from an improved management of Spanish forests.

本建築量體由兩個主要元素組成：一座重型混凝土底座以及可回收輕鋼和塑膠燈籠。基地作為所有機械的支撐，透過兩扇大型鍍鋅鋼門與外界以及位於地下的生物質筒倉建立地面連接；內部以走道圍繞中心機械，似藥丸圖型的環形分布使參觀者能夠獲得最佳的通行效果，同時覆蓋混凝土底座。而可觀的聚碳酸酯板外型，則藉三棱線結構配置成為似白色柔和面紗的意象，支撐在精緻的鍍鋅與噴漆鋼絲結構上。本案有效運用輕鋼和塑膠，重新詮釋工業建築典型的經濟解決方案，並以此與該社區建立了重要的連結――如同一座小型的能源大教堂。無論是基於能源和經濟循環所打造的幾何環繞結構，還是表達教育傳承層面的材質選擇，都使建築本體成為一種身份，展示其對於當地以及能源創新的重要意義。

The District Heating network runs under the streets of the capital of Palencia, carrying hot water produced with renewable energies mainly forest biomass to buildings in a good part of the city. The Central, on the other hand, fulfils a technical function hosting the hot water production processes but at the same time, it has a markedly pedagogical vocation desired by the client: to make the transformation visible and support and allow its dissemination. This double condition requires the approach to the problem of industrial construction not only as a strictly functional matter, where only the economic performance of the building matters, but in a more broadly architectural way.

Thus, the architecture of the Central is symbolic, both in its geometry based on energy and economic circularity and in its materiality which opts for literal and pedagogical transparency presenting the whole as an identity. Two main elements make up the building: a bathtub of heavy concrete and a light steel and plastic lantern recyclable. The base serves as support for all machinery and establishes terrestrial connections with the outside through two large, galvanized steel gates and with the biomass silo located underground. Inside, the concrete base has a cover that becomes a perimeter walkway that surrounds all the machinery. The pill-shaped floor allows optimal circulation of visitors around the complete energy process. The steel and plastic lantern reinterpret economical solutions typical of industrial buildings to establish a significant connection with the community it serves: a small cathedral of energy. The facade of polycarbonate sheets ribbed on three scales is configured as a soft whitish veil supported on a delicate galvanized and painted steel wire structure. As a final touch, a translucent tower expels the white smoke resulting from a filtering process that occupies most of the industrial space.
