About Boomerang Athens Primary Function: Хотын байшин

Book Text: Ликабеттус толгод дээрх хотын баян бүрд болгон бүтээгдсэн Boomerang Athens нь хувийн орон зай, гэрэл, дулааныг зохицуулдаг хяналттай нээлхий болон босоо сүүдэрлэх системээр төлөвшсөн тайван архитектурын дүр төрхийг харуулж байна. Металл, мод, гантигийн боловсронгуй өнгөний сонголт нь түүний минимал шинж чанарт дулаан уур амьсгал нэмж өгдөг. Дээвэр нь усан сан бүхий өндөр байрлалтай амьдрах орчныг бүрдүүлж, гэрэлтүүлэгтэй Boomerang Pergola нь шөнийн цагаар барилгын дүрсийг тодотгож өгдөг. Грек улсын анхны LEED Platinum гэрчилгээтэй орон сууц болох энэ байшин нь тогтвортой байдал, өндөр байгаль орчны гүйцэтгэлийг KNX программчлалаар дамжуулан өдөр тутмын тав тухтай байдалтай хослуулдаг.

Behind the Design

Press Kit

Unique Properties: Boomerang Athens is a 425 square meter filtered urban oasis: a monolithic volume wrapped in a ribbed second skin brise soleil that controls privacy, glare, and heat while framing precise carved openings. Natural materials, wood and marble, add warmth to a calm minimal palette. A roofscape with pool and the illuminated boomerang pergola completes the experience. First leed platinum residential in Greece, with knx scenes coordinating lighting, shading, and hvac for comfort and low energy.
Dimensions & Packaging: 425 square meter residential townhouse, arranged over five levels, three above grade, ground, and one basement. The house has four bedrooms, six bathrooms, roof pool, gym, lounge, elevator. Leed platinum, first certified residential project in Greece. Systems used as heat pumps, vrv and vrf, underfloor heating, pv and solar, knx automation for lighting, shading, hvac heat scenes.

Production Technology: Made through an iterative performance and craft method, as massing and openings were tuned with daylight and heat control goals, then refined into a ribbed second skin brise soleil for privacy and shading. Natural, durable finishes as wood floors, marble in wet and exterior areas, were selected for longevity and low emission specs aligned with leed platinum. Knx integrates lighting, shading, and hvac into scenes, reducing waste while improving comfort.
Design Challenge: The key challenge was creating privacy and calm in a dense Lycabettus hill while opening to light and views. Obstacles included tight urban constraints, neighborhood sensitivities, and integrating spa and pool plus five level circulation within a compact footprint. Leed platinum demanded rigorous material and iaq documentation and commissioning, while local supply chains required careful sourcing and detailing. Knx integration aligned multiple trades into one reliable, user friendly system.
Research: Type of research is applied building performance. Research objectives are comfort, privacy, daylight, low energy. Methodology is iterate massing and openings and second skin shading to leed goals. Data collection and research tools used are climate and daylight checks, energy and iaq targets, voc data. Participants or experiments are design and mep team, knx scene tuning. Results are leed platinum, lower glare and loads. Insights and impacts are passive filtering reduces system work. Effect is higher value, greener urban housing model.
Inspiration: Boomerang was inspired by the idea that what you give to the environment comes back to you. We translated this into a second skin townhouse that filters light, heat, and privacy through a ribbed brise soleil, carving precise openings for framed views of Athens. The research backbone is leed driven performance because of energy, materials, iaq and more and knx automation that choreographs lighting, shading and hvac into low energy comfort scenes, proof that sustainability returns as quality of life.
Project Duration: Design developed through a full shell reconstruction process, existing residence originally built in 2010, culminating in the completed boomerang athens as a 425 square meter five level townhouse in Lycabettus, Athens. The project achieved leed platinum certification, first cerified residential project in Greece, marking its delivery as both an architectural and performance benchmark. Started in 2024 and completed in September 2025.
Operation Flow: Operated through curated knx scenes that coordinate lighting, shading, and hvac. Arrival opens paths and comfort zones. Daylight optimizes glare and shade. Entertain sets layered lighting and ventilation. Spa pre conditions hammam and gym. Night secures and dims. Away reduces loads. The brise soleil facade and boomerang pergola passively filter sun and privacy, so systems work less, delivering steadier comfort with lower energy.
