Editor's Notes
- Human influenced climate change is upon us, fossil fuels are becoming scarce, rare metal and minerals are becoming scarce, species of plants and animals are disappearing at an alarming rate. And our society is doing so many things that make the planet less and less fit for our own survival. To paraphrase a Chinese proverb, the best time to change was 20 years ago; the second best time is now.
- Η Ελλάδα καλείται λοιπόν μόλις 6 μήνες μετά τη θέση σε ισχύ του ΚΕΝΑΚ 2017 να προετοιμαστεί εγκαίρως και να ενσωματώσει τις νομοθετικές αλλαγές που προβλέπονται στην οδηγία και ακολούθως, πάλι μέχρι τον Ιανουάριο του 2020, να προσαρμόσει τον ΚΕΝΑΚ και τις Τεχνικές Οδηγίες Εφαρμογής του. Βέβαια η χώρα μας έχει βεβαρυμένο ιστορικό καθώς ποτέ δεν ενσωμάτωσε εγκαίρως οδηγία για την ενεργειακή απόδοση κτιρίων. Αυτή τη φορά τα πράγματα είναι διαφορετικά, καθώς ήδη στην ΕΕ έχουν συμφωνήσει σε εξουσιοδότηση της Κομισιόν να λάβει μέτρα και το χρονικό σημείο συμπίπτει με την ολοκλήρωση των προγραμμάτων ΕΣΠΑ που χρηματοδοτούνται από κοινοτικούς πόρους… Επομένως η χώρα μας στη συγκεκριμένη περίπτωση δεν διακινδυνεύει μόνο με παραπομπή στο Ευρωδικαστήριο και πρόστιμο, αν και πάλι δεν ενσωματώσει εγακίρως την κοινοτική οδηγία, αλλά και με «πάγωμα» ή (ακόμη χειρότερα) «ανάκτηση» χρημάτων που έχουν δοθεί στη χώρα για το ΕΣΠΑ 2014-2020. Πρακτικά, όλα τα προγράμματα εξοικονόμησης ενέργειας που χρηματοδοτούνται από κοινοτικούς πόρους θα πρέπει από τον Ιανουάριο του 2020 να είναι προσαρμοσμένα στις απαιτήσεις της νέας οδηγίας, καθώς αποτελεί προϋπόθεση νομιμότητας της χρήσης των κοινοτικών πόρων η εναρμόνισή τους με την κοινοτική νομοθεσία. Επομένως, ενόψει των προγραμμάτων εξοικονόμησης ενέργειας που επίκεινται (όπως αυτό για τη βιομηχανία, τις μικρομεσαίες επιχειρήσεις ή για τα δημόσια και δημοτικά κτήρια) είτε η χώρα μας θα πρέπει έγκαιρα μέχρι τον Ιανουάριο του 2020 να υιοθετήσει νομοθετικά τις αλλαγές στη νομοθεσία και τα συνοδευτικά κείμενα (ΚΕΝΑΚ, ΤΟΤΕΕ, κλπ) ή με την έναρξη της νέας οδηγίας θα μπει «κόφτης» από την Κομισιόν στα χρηματοδοτικά προγράμματα εξοικονόμησης ενέργειας. Εκτός και αν η Κυβέρνηση επιλέξει σε όλα τα προγράμματα εξοικονόμησης ενέργειας να βάλει ρήτρα ολοκλήρωσης φυσικού και οικονομικού αντικειμένου μέχρι το 2019…
- The Passivhaus Standard is different. Unlike most environmental standards for architecture, design is central to the Passivhaus Standard. And the Passivhaus Standard is central to the design process. The Passivhaus Standard is often referred to as “the world‘s leading standard in energy efficient design.” And usually a description of the standard includes details of the specific technical requirements.
- Especially the quality assurance is only possible if a certification procedure follows the design and implementation. The performance gap that is rife in the construction industry, is due in part to buildings not being constructed in accordance with the design details. There are various reasons for this and blame does not lie wholly with any one party. However, the passivhaus certification process involves checking what is built on site and this ensures that the construction accurately matches the design details.
- The first thing you read about Passivhaus is often the set of technical requirements and performance metrics. It’s got to be airtight. No thermal bridges are allowed. 1 5kWh/m2.a, 10W/m2, 120kWh/m2.a, 0.6 ach. . . But these figures don’t help you understand how to design a Passivhaus building. These figures don’t tell you what is different about designing a Passivhaus building to designing any other building. Well, we should not let the performance metrics of Passivhaus put us off, we should understand the design approaches and get started. The Passivhaus Standard delivers exceptional indoor comfort and building energy efficiency. To do this, a high-performance thermal envelope is required. In basic terms, this means super-insulation, thermal bridge free design, airtightness, High-performance windows and a controlled ventilation.
- ‘Super-insulation’ is a relative term and does not always mean extremely thick insulation though. The greater the amount of external surface area a building has, relative to the floor area of the building, the greater the thickness of insulation that will be required. The less surface area relative to the floor area, the less thick the insulation can be. Insulation keeps the heat inside the building. And equally important, it keeps unwanted heat out. So Insulation reduces the flow of heat energy in both directions through the building envelope.
- Windows, doors, rooflights, curtain walling and any other glazed elements often lose (or gain) significantly more heat than the surrounding walls or roof of the thermal envelope. For this reason, the international Passivhaus Standard pays particularly close attention to the design and specification of glazed elements. Ideally, windows would provide wonderful views and abundant daylight, whilst at the same time losing very little heat and providing just the right amount of solar heat gain. A Passivhaus window is certified on the basis of the frame with a set glazing specification. When the glass is specified for a Passivhaus building it is always a balance between the U-value (minimising heat loss) and the g-value (optimising solar heat gain).
- An airtight barrier on the inside of the insulation does several things: It stops air (and therefore heat energy) that is inside the building from escaping through uncontrolled gaps in the building envelope. It prevents moisture from inside the building getting into the building envelope where it might come into contact with a colder surface and condense. It preserves the performance of the insulation. A windtight barrier on the outside of the insulation is also required to preserve the performance of the insulation. Wind blowing across, or even worse, into the insulation, can reduced the performance of the insulation by as much as 40%.
- Every building, airtight or not, needs a properly designed, installed and functioning ventilation system. Plentiful fresh clean air at comfortable temperatures needs to be provided to the people inside the building, all year round. Infiltration air – where it has leaked in through gaps in the building envelope – cannot and will not provide this. Mechanical ventilation is simply a duct coming into the building with a fan blowing fresh air in and a duct going out of the building with a fan blowing stale air out. Since the fans are powered and controlled, the ventilation is considered “mechanical” as opposed to a ventilation system with no power and no control such as ‘natural ventilation’. Heat recovery is using a heat exchanger that takes the heat from warm air and gives it to cold air. The air inside a building is typically warm because it has been heated in some way so that the rooms are comfortable to inhabit. On the other hand, outside air is typically colder than indoor air for a large part of the year. Often, outdoor air is colder overnight all year round. This is the case even in climates we generally consider to be warm. By using a heat exchanger, fresh cold outside air can be warmed up to a comfortable temperature by using the heat of the warm stale indoor air as it is extracted.
- Behind the success of the [Passivhaus] Standard lies the Passive House Planning Package (PHPP), the Passive House energy balance and design tool. A tool of proven accuracy and demonstrated reliability in predicting building energy consumption… The so called PHPP is one of the most powerful design tools available for designing low energy buildings. It can seem intimidating as an extensive programme of interlinked worksheets, typically used in Microsoft Excel. However, when viewed worksheet by worksheet is it apparent how straightforward it is. It is a necessary part of Passivhaus design, both for Passivhaus Designers and Consultants and for Passivhaus Building Certifiers. For designers, it is a useful tool at all stages as detail is gradually built up. And it provides a large degree of the all-critical quality assurance of the international Passivhaus Standard. And finally it is the tool used for certification of a Passivhaus Building.
- The PHPP does require detailed information to be built up during the design process, it is accurate enough to be useful at each stage. It isn’t a ‘rapid energy modelling’ tool that gives rough outputs that don’t correlate to real world performance. Genuine sustainable design requires work; it is simple but not necessarily easy.
- So because of all these reasons the passivhaus standard is the gold standard for low energy and occupant comfort across the globe. It is backed by over 30 years of data demonstrating that it delivers what it promises, something no other standard comes close to. And certified passivhaus buildings maintain performance over time. It is appicable to appartment buildings
- appicable to schools
- APPLICABLE TO NEW MIXED-USE DISTRICTS
- APPLICABLE TO TALL URBAN INFILL
- APPLICABLE TO ART MUSEUMS
- APPLICABLE TO RENOVATIONS
- Passive House is everywhere with more than 100.000 units globally.
- Passivhaus is a team sport. While climate change and architecture are both global issues, the passivhaus standard applies to all kind of buildings in all locations and climates. Passivhaus excels in providing a direct way to tackle the potentially overwhelming issue of climate change. Passivhaus professionals are of course engaged in policy change and advocacy at all levels across the globe. However, the day-to-day work of passivhaus professionals is often in the nitty-gritty of solving technical challenges with buildings. And the passivhaus community is here to support each other in solving these challenges too. And the global passivhaus community is not exclusive; it’s open to anyone. It’s constantly evolving and growing. Each year more people get involved, more research gets carried out and more passivhaus buildings appear across the globe.
- And the global passivhaus community is not exclusive; it’s open to anyone. It’s constantly evolving and growing. Each year more people get involved, more research gets carried out and more passivhaus buildings appear across the globe.
- The highest levels of many other energy standards, national and international, seem to come close or at least be comparable to Passive House in terms of their energy use requirements, but beware because the difference is in the details.
- And believe me! Once you have some insight and understanding into how passivhaus actually works, your eyes have been opened wide to the reasons why buildings perform badly. You know architecture can be better. You know architecture doesn’t have to contribute excessively towards climate change.
- So please do the next step and go where the magic happens.
