被动房体验
The Passive House Experience

不是节能标签
是感官设计

Not an energy label.
A sensory design.

住在里面，你会彻底卸下身体负担，不用再操心今天冷不冷、潮不潮、吵不吵。房子稳定，人才能从容。

Passive House works through the building envelope, not machinery. Year-round comfort maintained naturally. The result: you forget your body is there.

01
你摸不到一扇烫手的窗
No scorching windows, ever
夏天正午，用手触碰被动门窗内侧——你会感到微微凉意，而不是灼烧。三玻两腔 Low-E 玻璃，把室外的热截在外面。
Touch the inner glass pane at noon in summer — slightly cool, not burning. Triple-pane Low-E glass keeps outside heat outside.
02
你睡着了，也在呼吸新鲜空气
Fresh air while you sleep
关上所有门窗，CO₂ 浓度依然在 800ppm 以下。热回收新风机持续换气，全热回收效率75%，你在室内没有任何风吹在身上的感觉。
All windows closed. CO₂ still below 800 ppm. HRV continuously exchanges air with 75% total heat recovery — you feel no draft anywhere in the room.
03
梅雨季回南天，家里没有霉味
No damp smell during plum rain season
气密层包裹整栋建筑，室外湿气进不来。室内湿度常年稳定在 40%~60%，低于人体感知湿意的阈值。
Continuous airtight envelope. Outdoor moisture stays out. Indoor humidity held year-round between 40–60%, below the threshold where you feel damp.

ELE HOME 5+3 Complete System

5大被动系统，让房子自己调节气候。3项主动延伸，让体验更进一步。从建筑到生活，缺一不可。5是基本功，+3才是巢象的答案。

🧱
01
高效的保温隔热
High-Performance Insulation
保温不是越厚越好——根据气候区和建筑本身情况，科学判定材料与厚度。冬天保温，夏天隔热，给房子穿衣戴帽。
Thicker isn't always better. We determine the right material and thickness based on climate zone and building condition. Insulate in winter, shield in summer.
🪟
02
高性能门窗
High-Performance Windows
每个项目四面朝向独立计算，基于365天日照数据定制配置方案——不是越隔热越好，是越适合越好。从设计到安装全程把控。
Each orientation calculated independently. 365-day solar data drives every window specification. Not about maximum insulation — about being right for the project.
🔗
03
近无热桥设计
Near Thermal-Bridge-Free
排查建筑所有薄弱环节，每个节点进行热流分析，确保不结露不发霉。追求实用平衡而非理论完美——解决冷凝问题，同时降低施工难度与造价。
Every weak point inspected, every junction thermally analyzed. We aim for practical balance — solving condensation risk while keeping construction feasible and costs controlled.
🔒
04
良好的气密性
Airtight Envelope
不是门窗气密就够了，是整个房子要密闭。针对穿墙管道、门窗连接等薄弱环节做系统性加强。
Not about window seals alone — the whole house must be tight. We systematically strengthen every weak point: penetrations, window-wall junctions, and more.
🌀
05
高效新风热回收
Heat Recovery Ventilation
冬天排出的废气加热进来的新风，夏天室内的凉气给热空气降温——让更多能量留在室内。持续换气，不闷不燥。
Winter exhaust preheats incoming fresh air. Summer indoor cool air pre-cools the hot outside intake. More energy stays inside. Continuous ventilation, no stuffiness.
+01
辅助供冷供热
Auxiliary Heating & Cooling
被动房已经大幅降低了冷热负荷，但仍需一套轻量级的辅助系统来应对极端天气。小功率设备即可覆盖全年需求，能耗仅为常规建筑的零头。
Passive design drastically cuts heating/cooling loads. A compact auxiliary system handles extreme days — energy use is a fraction of conventional buildings.
+02
可再生能源利用
Renewable Energy
有条件的情况下，引入光伏、光热等可再生能源系统，进一步降低运行能耗，朝近零能耗甚至产能型建筑迈进。
Where conditions allow, integrate solar PV and thermal systems to drive operational energy toward net-zero — or even energy-positive.
+03
智能化运维
Smart Operation
减少人为干预，让房子自动运行在最佳状态。多传感器联动，系统自己判断什么时候换气、什么时候调温，你不必操心。
Minimize manual control. Multi-sensor orchestration lets the house decide when to ventilate, when to adjust — running at its sweet spot automatically.
常见问题
FAQ

你可能想知道的

Questions you probably have

被动房和五恒系统有什么区别？ Passive House vs. "5-constant" systems — what's the difference?
+
五恒是从设备层面解决舒适度和健康度问题，被动房是从建筑层面解决。建筑级的装修方案包含了设备级——当我们把建筑本身做好了，设备选择就变得很简单了。 "5-constant" systems solve comfort and health at the equipment level. Passive House solves it at the building level. Building-grade solutions encompass equipment — get the envelope right, and equipment decisions become simple.
被动房造价比普通装修贵多少？ How much more does Passive House cost vs. standard renovation?
+
通常增量成本在 500~1000 元/平方，具体取决于建筑类型和气候区。考虑供暖制冷能耗节省约 70%左右，通常在 10~15 年内可收回增量成本。对于自住项目，体验价值往往是业主最终决策的主要因素，而不是回收期。 Typically 500–1000 RMB/m² premium depending on building type and climate. With around 70% savings in heating and cooling, the premium is usually recovered within 10–15 years. For owner-occupied homes, comfort experience is typically the deciding factor rather than payback period.
EPC 总承包是什么意思，你们做到哪一步？ What does EPC contracting mean? What exactly do you cover?
+
EPC = 设计（Engineering）+ 采购（Procurement）+ 施工（Construction）总承包。巢象负责：前期能耗模拟 → 方案设计 → 施工图 → 材料采购 → 施工管理 → 气密性测试 → 验收交付，业主不需要对接多个分包，一个合同搞定全部。 EPC = Engineering + Procurement + Construction. ELE HOME handles: energy modeling → design → drawings → material sourcing → construction management → blower door testing → handover. One contract, one contact, start to finish.
南方气候（上海、广州）能做被动房吗？ Does Passive House work in hot-humid climates like Shanghai or Guangzhou?
+
完全可以。PHI 已发布适用于各气候区的认证标准，包括炎热湿润气候。在南方，被动房的核心价值是隔热、防潮、过滤 PM2.5，夏季可大幅降低空调负荷。巢象在上海、广州均有已交付项目。 Yes. PHI has certified standards for all climate zones including hot-humid. In South China, the key benefits are heat rejection, moisture control, and PM2.5 filtration. ELE HOME has completed projects in both Shanghai and Guangzhou.
旧房改造能达到被动房标准吗？ Can an existing building be retrofitted to Passive House standard?
+
可以做到 EnerPHit 标准（PHI 专为改造项目制定），气密性要求略低（n50 ≤ 1.0/h vs 新建 ≤ 0.6/h），其余指标基本相同。改造难点在于气密层连续性和结构热桥处理，这是巢象最核心的施工能力之一。 Yes, to EnerPHit standard — PHI's certification for retrofits. Airtightness target slightly relaxed (n50 ≤1.0/h vs ≤0.6/h new build). All other targets remain. The challenge is airtight layer continuity around existing structure — one of ELE HOME's core competencies.
如何开始合作？第一步做什么？ How do we start? What's the first step?
+
联系我们后，先进行一次免费的项目初步咨询（约 1 小时），了解项目情况、气候区、预算范围，给出初步技术建议和概算造价。满意后签署设计合同，开始能耗模拟和施工图设计。 After you contact us, we start with a free 1-hour consultation — project overview, climate zone, budget. We provide a preliminary technical recommendation and cost estimate. If you're satisfied, we sign a design contract and begin energy modeling and construction drawings.
