PULSA，與淺水灣的一次對話

淺水灣是香港最高檔的住宅區(qū)，面朝大海，背靠青山，新月形的海灣有著旖旎的熱帶風(fēng)光，群山青翠欲滴是中國傳統(tǒng)的山林景色。Aedas受業(yè)主委托，要在風(fēng)景如畫的淺水灣半山坡建造8幢可以盡享美景的獨(dú)棟豪宅。

在這里建造豪宅并不難，但要在不破壞自然美景的同時，讓住戶和行人最大程度享受自然美景，是個極具挑戰(zhàn)的事情。項(xiàng)目設(shè)計(jì)師柳景康（Cary Lau）給出的答案是：融入它、成為它、享受它。

“當(dāng)建筑融入自然，成為自然的一部分，破壞也就無從談起了?！痹O(shè)計(jì)師柳景康從建筑的外形和分布兩方面考量，讓PULSA與自然融為一體。

地塊周邊滿是枝繁葉茂的大樹，郁郁蔥蔥，自然氣息濃重。設(shè)計(jì)沒有選擇硬冷的四方形體量，而是就地取形，以淺水灣最常見的海浪為藍(lán)本，借用它富有律動、變化萬千的線條勾勒建筑輪廓，讓建筑變得生動、富有自然氣息。每一幢、每一層都是獨(dú)一無二的線條，彼此區(qū)別，又相互聯(lián)系。從周邊走過，不同的角度會看到建筑不同的樣子，像極了瞬息萬變的海。建筑外立面的材料也精心挑選了玻璃幕墻，當(dāng)陽光在起伏的曲線玻璃上衍射，便把周邊的風(fēng)景倒映在上面，一步一換，建筑的表面上總是自然風(fēng)景。

地塊不是規(guī)整的幾何形狀，兩側(cè)需按規(guī)定預(yù)留非開發(fā)緩沖區(qū)，可使用面積十分有限，8幢住宅勢必要分成兩排。地形狹長且復(fù)雜，低處有弧度，沒有全部正對淺水灣，地處40°斜坡，高差大約22米，勢必會造成實(shí)現(xiàn)遮擋。這一系列限制因素導(dǎo)致住宅的高度和朝向需要慎重抉擇，否則海景視野將大打折扣。

橫向比較了多種方案，最終設(shè)計(jì)師柳景康選擇順應(yīng)山勢，充分利用高處的視野優(yōu)勢，上5下3階梯式排列住宅，并將上排地基抬高2米。既避免視線遮擋將上層高處視野價值發(fā)揮到最大，又不影響住宅空間的舒適感，同時保證下層住宅可以擁有更多正面角度朝向淺水灣，讓每棟住宅都能擁有最大化的海景景觀。并將坡度劣勢轉(zhuǎn)化為空間優(yōu)勢，充分利用住宅與山形成的夾角，將車庫、后勤機(jī)電等功能隱藏其中，不但減小了住宅對山體地形的破壞，還降低了配套功能空間對住宅外觀的破壞。

“融入自然只是開始，從時間的維度去計(jì)算影響，才是有意義的。” 設(shè)計(jì)師柳景康在建筑綠化節(jié)能上做了很多考量。預(yù)先規(guī)劃出多處綠化場地，街墻內(nèi)、建筑間，并在每幢住宅屋頂設(shè)置綠色景觀平臺。采用中空LOW-E鍍膜玻璃作為外立面，使用對流窗，并設(shè)置了屋頂泳池、架空地臺，全方位遮陽隔熱提升節(jié)能效果。住宅獲得了綠建環(huán)評（BEAM）金級評審。

設(shè)計(jì)師柳景康表示：“在設(shè)計(jì)之初，我和我的團(tuán)隊(duì)就在思考，如何才能減少破壞和突兀，它屬于自然，也屬于它自己?！?/p>

Pulsa - Sea Waves by the Bay

Repulse Bay is among the most luxury residential areas in Hong Kong. Backed by mountains, Pulsa is steeply sloped with spectacular sea view of the Bay. Eight houses are arranged in two tiers to optimize sea views, yet minimizing disturbance to the natural slope.

“When the architecture is integrated with nature and even becomes its integral part, damage to the environment is minimised.” According to Aedas Executive Director Cary Lau. Embracing residents and visitors with nature is what Cary’s design plans to achieve.

Surrounded by lush landscapes, the design motif of Pulsa is inspired by sea waves. Different floor area, layout, building profile and materials have been adopted, bestowing each house a unique identity in a coherent statement.Facades of houses create diffractions and reflections, creating ever-changing perspectives from different viewing angles, to surround residents by the natural beauty of Repulse Bay.

Located on a slope of approximately 40 degrees, the plot is originally in irregular geometric shapes. Not-for-development areas need to be reserved as required by regulations, to provide reasonable buffer between the adjoining developments.Nonetheless, Cary managed to optimize space and desirable views by arranging houses in two rows.

“Integrating nature into architecture is just the beginning. We should focus on its long term impact, to make our design meaningful.” Cary has put thorough considerations to reduce carbon footprint for Pulsa. The project achieved BEAM plus GOLD in Provisional assessment for its environmentally-friendly design and selection of materials. Different Low-E coatings not only control glare, but also reduce heat transfer across building envelops. The design applies cross-ventilation to enhance thermal comfort, while outdoor swimming pools are set on roof floor and the floor system raised on roof, to enable an effective energy- saving architecture.

"From day one of our design process, our team has already been thinking solutions to lower impact on the environment. Pulsa made it. This is a project belongs to both nature and itself.” Cary said.
