Good Insulation keeps heat outside in summer and traps heat in winter
"台灣被動式房屋論壇" 是第一個和國際被動式房屋機構IPHA (International Passive House Affiliate) 合作在台灣成立的組織，我們是百分之百台灣所擁有的組織，我們提供”被動式房屋/建築設計”的知識和技術，透過使用PHPP軟體，確認建築物能取得Certified Passive House 認證。”台灣被動式房屋論壇”成立的目的是期望在地所建造的建築物，能夠符合世界上最高標準的建築能源使用效率，也就是國際被動房屋設計標準。
No matter for a new built building or refurbishment of exsiting one, there should be a basic requirement of air exchange rate. This principle is to make sure the interior CO2 below 1000ppm. The air quality is supposed to be related with the users' comfort and their working productivity. BWK uses mixed-mode ventilation strategy to support clients' projects. In some situation like summer night, NV could be introduced to flush up still air. In other situation, mechanical ventilation with heat recovery would be activated to replace window ventilation.
When MVHR system is mainly installed for whole building ventilation, fresh air is supposed to deliever to living area like living room and bedroom. That is for hygiene issue air will be extracted from kitchen, toilet or even storage room whose air is with wet and unpleasant smell. The air automatically and gentlely flow through supply and extraction area with positive pressure and negative pressure. By this way, it is confirmed that the air of the whole building is continuely replaced by fresh and filtered air.
MVHR is crucial for Passive house design. And it makes sure the internal space air always fresh. In terms of its structure, the different streams of air are separated by profiled metal or PVC plates. With the use of ducts (fin-counter-flow heat exchanger) it is possible to further increase the relevant heat exchanging area.
Planners and designers can acquire the necessary substantiated expertise in further training courses and seminars. A large range of courses are available now. Another form of advanced education is through practical implementation. An architect who has already planned and built a certified Passive House indisputably possesses the necessary know-how. The certificate shows the building owner that the designer or consultant has acquired the knowledge and experience relevant for planning or consultancy services for Passive House projects.
The PHPP is an easy to use planning tool for energy efficiency for the use of architects and planning experts. The reliability of the calculation results and ease of use of this planning tool has already been experienced by several thousand users. In addition, project data of a building model created in designPH can be exported to IP-PHPP, just as in the metric versions of PHPP. Users of the IP-version of PHPP can also enter their projects in 3D with the SketchUP-plugin designPH, before refining the data in the Passive House Planning Package.
The Passive House requires high quality components: super-insulating window frames, highly efficient ventilation units, airtightness materials, thermal insulation...and so on. Certified Passive House suitable products allow users to verify and compare the relevant parameters of the respective products.
