Here is a passive wooden house in the Veneto countryside.
The project
This is a single-story property of about 150 sq. m. comprising 3 bedrooms, a large living room, technical rooms and lofts. Adjoining on the east side is a porch with garage and solarium on the flat roof.
The setting
The floor plan layout is classic: it provides a living area to the south and a sleeping area to the north. The design approach provides a generous open space with a countertop kitchen and TV area.
The space is enhanced by a generous glass window with lift-and-slide doors that allows people to enjoy the surrounding space and capture free solar energy in the winter time.
A restructuring
The project involved the demolition of an existing ruin and the new construction of a passive wooden house according to our standards.
The structure
The vertical structure was made of 10-cm-thick XLam panels, while the roof was made of glulam beams.
Foundations
The foundations are rafted. As per the construction technique used, the Xlam panels were mounted on concrete curbs that rise from the slab in order to ensure the detachments of the wood from the surrounding soil.
Insulation and installations
This new house was built by providing:
- 20 cm mineral wool coat;
- 6 KWp photovoltaics;
- 10 KWh storage batteries;
- EV charging column;
- hydronic heat pump;
- Triple wood windows and doors with aluminum exterior;
- central mechanical ventilation(CMV).
Energy independence
This is a passive house with very limited consumption (around 10 KW/sqm/year). There is no connection to methane gas, and the provision of photovoltaics with storage ensures semi-self-sufficiency in energy. Our service included the following works and services:
Zero-mile passive house
As per international guidelines Passivhouse materials and work suppliers are local, this allows a reduction of gray energy during construction and better traceability of supplies to better ensure after-sales service.
Design
The project carried out by Lignodesign included:
- architectural executive design;
- Structural and facilities design;
- Reinforced concrete storage and testing;
- seismbonus practices;
- Enea eco bonus affidavit.
Digital modeling
Every building element is digitized using BIM technology that allows perfect visualization and quantification of every detail of the property.
Construction site setup
Site setup with provision of crane, toilet, temporary fencing, standardized scaffolding and other necessary devices to ensure safety. Temporary construction site connection and water will be provided by the client.
Excavation
Machine-executed general overburden excavation with partial piling on site of material for the recovery and/or reuse of topsoil, performed up to the collar of the foundations. Execution of excavation for all foundations up to the level of impost, for buried piping and installations.
Foundations
Unreinforced concrete lean-to foundation. Concrete slab foundation (30 cm) cast with the aid of formwork according to the dimensions specified in the project, including iron reinforcement.
Insulation against ground
An insulating layer and a layer of lightened foamcem screed was made at ground level to house the systems.
Vertical structures
Perimeter load-bearing walls in Xlam of Italian PEFC certified production of the standard 100 mm type (or if required of larger dimensions complete with fasteners type Rothoblaas or Borga Italia. XLam load-bearing wall, composed, in sequence from the inside to the outside by :
- double sheet of 12.5 mm plasterboard; in the case of facing the bathroom, water-repellent plasterboard will be used;
- 50 mm cavity for plant passage with 5×4 cm fir laths insulated with 50 mm rock wool (or thicker for any larger diameter pipes);
- 100 mm 3-layer XLam load-bearing wall (depending on structural calculations);
- 200 mm rock wool coat density >135 kg/m3, l = 0.037 W/mK;
- 5mm mineral plaster with plaster carrier mesh and siloxane finish.
The structure in X Lam, how it contributes a passive house in the Venetian countryside
Invented by a group of wood-frame manufacturers in Austria in the late 1990s , XLam makes it possible to create both contemporary and classic architecture with a sustainable and environmentally friendly material with the appearance of traditional masonry but with the benefit of:
- Increased speed of construction;
- low energy consumption;
- Very high seismic resistance.
Roof
The roof of this passive wooden house in the Veneto countryside was built with a load-bearing structure of pre-painted glulam beams of the color white including:
- mm 20 wooden bead;
- mm 25 45° planking;
- Vapor barrier;
- mm 200 Rockwoll Hardrock type high-density rockwool insulation for roofs;
- Ventilation lath and counter lath;
- Tile roof tile in the color of your choice in terracotta from San Marco Brickworks.
Window frames of a one-story zero-consumption house in the Venetian countryside
The window and patio door frames made of laminated wood complete with tilt and turn, burglar-proof system, standard handles, triple-walled double glazing 4/22/4/22/4 gas and in patio doors part under glass 6/6+16+6/7, totally in accordance with energy-saving regulations, CE mark of the dimensions as per the project.
Photovoltaic system
6.5 kwp photovoltaic system (with panel and inverter) with integrated panels with inverter and GSE connection arrangement.
Thermal power plant
The main generator will be an air-to-water heat pump of approximately 12 kw thermal to create hot water for heating and Sanitary Hot Water production and cool water for air conditioning and dehumidification in the summer phase. 300-liter kettle for production and storage of Domestic Hot Water for sanitary uses.
In comfort of a passive house in the Veneto countryside: the heating/cooling system
Heating/cooling will be done in radiant floor mode. Plasterboard panels will be built into the wall with pipes embedded inside where hot water created by the heat pump will flow and give the room the energy needed to heat. In the same panels will flow cool water in the summer phase for radiant air conditioning.
Climatic mechanical ventilation system
This system integrates a system that constantly reciprocates the air mechanically inside the house by recovering the heat present in the outgoing air (enthalpy) and a the system that will dehumidify the air in the summer phase in order to make the environment perfectly air-conditioned. A passive wood house in the Venetian countryside primarily requires good air exchange since the Venetian plain is well known to be hot and humid and therefore regular air exchange is essential in order not to have a closed smell.
Mechanical ventilation reciprocates air constantly, taking it from the ‘dirty’ compartments (bathroom, kitchen, laundry room) and putting it back into equiportment in the noble compartments (bedrooms, living room…). This replacement is done through a machine that recovers the heat of the extracted one by preheating the newly introduced replacement one. The dehumidifier is installed on the ventilation supply so that it can provide dehumidified ventilation in the summer phase. This makes it possible, in conjunction with radiant cooling panels in the summer period, to provide radiative air conditioning in the warmer periods.
The post was very good, I appreciate how you explain it, Keep the posts coming! Very good talent.

ocenili váš obsah. Dejte mi prosím vědět.
O conteúdo existente nesta página é realmente notável para a experiência das pessoas,
Together with almost everything which appears to be developing inside this particular area, a significant percentage of viewpoints are generally very refreshing. Nonetheless, I beg your pardon, but I do not give credence to your whole theory, all be it radical none the less. It would seem to us that your comments are actually not totally validated and in reality you are generally yourself not completely confident of your argument. In any case I did enjoy reading through it.
Please let me know if you’re looking for a article writer for your site. You have some really great posts and I feel I would be a good asset. If you ever want to take some of the load off, I’d love to write some content for your blog in exchange for a link back to mine. Please shoot me an e-mail if interested. Many thanks!

Hmm it looks like your blog ate my first comment (it was extremely long) so I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog. I too am an aspiring blog writer but I’m still new to the whole thing. Do you have any tips for beginner blog writers? I’d really appreciate it.
Audio began playing as soon as I opened up this web-site, so irritating!
Wonderful website you have here but I was curious about if you knew of any user discussion forums that cover the same topics discussed in this article? I’d really like to be a part of group where I can get feed-back from other knowledgeable people that share the same interest. If you have any suggestions, please let me know. Thanks!

I’ve been browsing online more than 3 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. In my opinion, if all webmasters and bloggers made good content as you did, the net will be much more useful than ever before.
Great blog here! Also your web site loads up very fast! What web host are you using? Can I get your affiliate link to your host? I wish my website loaded up as fast as yours lol
Hello! Do you know if they make any plugins to safeguard against hackers? I’m kinda paranoid about losing everything I’ve worked hard on. Any suggestions?

Howdy just wanted to give you a quick heads up. The text in your article seem to be running off the screen in Opera. I’m not sure if this is a format issue or something to do with browser compatibility but I figured I’d post to let you know. The design and style look great though! Hope you get the problem resolved soon. Kudos

My spouse and I absolutely love your blog and find nearly all of your post’s to be just what I’m looking for. Would you offer guest writers to write content for you? I wouldn’t mind composing a post or elaborating on some of the subjects you write in relation to here. Again, awesome web site!
I’m extremely impressed with your writing skills as well as with the layout on your blog. Is this a paid theme or did you modify it yourself? Anyway keep up the excellent quality writing, it’s rare to see a great blog like this one today..
meget af det dukker op overalt på internettet uden min aftale.
It’s a shame you don’t have a donate button! I’d most certainly donate to this superb blog! I suppose for now i’ll settle for book-marking and adding your RSS feed to my Google account. I look forward to brand new updates and will talk about this site with my Facebook group. Chat soon!
Woah! I’m really enjoying the template/theme of this website. It’s simple, yet effective. A lot of times it’s hard to get that “perfect balance” between user friendliness and appearance. I must say that you’ve done a awesome job with this. In addition, the blog loads super quick for me on Opera. Excellent Blog!
reading this weblog’s post to be updated daily.
Have you ever considered creating an e-book or guest authoring on other websites? I have a blog centered on the same subjects you discuss and would love to have you share some stories/information. I know my subscribers would value your work. If you are even remotely interested, feel free to send me an e-mail.
Děkuji|Ahoj všem, obsah, který je na této stránce k dispozici.
Hiya! I know this is kinda off topic nevertheless I’d figured I’d ask. Would you be interested in exchanging links or maybe guest writing a blog article or vice-versa? My site discusses a lot of the same subjects as yours and I think we could greatly benefit from each other. If you’re interested feel free to send me an email. I look forward to hearing from you!
