In order to address Living Building Challenge’s Water Petal, EcoBiblioteca has to reach a zero water level of extraction from public utilities. The water management concept regarding EcoBiblioteca assures that the water needed for daily use is taken from unconventional sources :

  • Groundwater, extracted from well has been tested and proven to be healthy – used as potable water source;
  • Rainwater / Stormwater – collected from the roof and used for non-drinking purposes;
  • Blackwater (water used by lavatories and toilet) – treated and re-used inside the same system.

This innovative MEP project is signed by CUNDALL, Romania Green Building Council Gold Member, through the work of Engineers David Clark and Vassilios Giannakos.

EcoBiblioteca project is using Magnesium Oxyde and PIR Structural Insulated Panles provided by Ozone Homes

As EcoBiblioteca project is pursuing the sustainable certification system Living Building Challenge, the renovated building of the library must reach a zero energy consumption level used for heating and cooling the indoor air. Therefore, having a highly thermal-efficient building envelope  is essential. But, in order to maintain the traditional look of the façade, the designers chose to clad it in horizontal wood planks. So, in order to support this additional weight, the insulated panels must also have rigid properties.

 

Most of the structural insulated panels (or shotly SIPs) are made as a sandwich of rigid OSB faces and polyisocyanurate  foam (PIR). But in order to achieve the Living Building Challenge’s Materials Petal, none of the elements used in the project can contain traces of the substances included in the list of forbidden construction materials  (Red List) that has been issued by the Living Future Institute. The fact that most of the wood – based products contain formaldehydes or other added flame retardant substances directed us to find alternative solutions.

 

The structural insulated panels acquired from Ozone Homes are of two kinds, judging by  the material used to support the faces of the sandwich. The middle is the same –PIR, having as prime matter locally harvested rapeseed oil – but the faces of the panel are made of Red List-friendly and FSC –certified OSB layers (the SIPs), respectively Magnesium Oxide sheets (the DIP panels).  The latter  material is fireproof, bu also water-resistant, which allows for it to be used both underground, for insulating the base and wet areas, and as false ceiling with insulating and fire-resisting properties. It looks similar to gypsum board, and supports both plaster-based finishes and screw-fixed solutions, so that the exterior finishing of the panel is opend to more than one options. In addition to these features, 65% of the product is recyclable, which makes it a truly green option.

 

So far, three facades have been clad in DIP panels.  The construction site of EcoBiblioteca has been re-opened this week, and amongst the first scheduled works are placing the structurally insulated panels  on the northern façade, but also starting to place the  interior ones, that act as flooring support and false ceiling mounted beneath the beams.

We’ll be back soon with construction site pictures.

Thermaflex company has been actively involved in “Green Library” project, providing non pollutant solutions that can ensure energy loss reduction and implicitly the decrease of CO2 emissions.

To ensure the link between the technical room and the library building, there have been used 2 pre-isulated pipes Flexalen 600, De 32mm, return pipes with a total length of 15 meters. The main pipe,  made of polybutylene (Polybutene PB1) provides a life-cycle of more than 50 years, for temperature of maximum 95 °C, and assures lasting properties over the entire exploitation period at a pressure of maximum 8 bars.  The pipage covering is made of polyolefins foam with closed cells that provides a thermal conductivity  of less than 0,032 W/mK. Due to its cellular structure, the covering blocks water absorption. Having a high flexibility and being a heat-sealable material, the installation price is very low, in comparison with classical systems.

 

 

 

 

 

 


For thermal energy distribution inside the building, there will be used polybutylene pipes with a diameter of 16 and 20 mm, covered with thermal insulation, Thermacompact  type. Both insulation and pipes are 100% recyclable and do not contain environment-unfriendly substances. The pipes and fitting pieces can be welded, so the resulting system is homogenous and very reliable.

 

Thermacompact insulation is made of polyolefins foam, having a red  co-extruded  membrane on the exterior. This membrane gives good physical properties and can be fixed in masonry or screed.

 

 

 

 

 

 

 

 

All the materials recommended for this project have been carefully analysed in order to match the ecological requirements and to ensure the transport and thermal energy distribution with minimum loss.

Velux installs daylight solutions for ecoBiblioteca

As the main facade of the ecoBiblioteca is facing north, no natural light is available directly.  In a project that  limits the use of articial lighting, this problem has become an opportunity to figure out an intelligent solution.

The design team chose Velux innovative Sun Tunnel. The product was chosen for its ability to bring light through the void in the attic into the interior space, on the north-facing facade of the building.

One sun tunnel brings daylight into the toilet area (which has no window) and the other into the library lobby.

For the lobby Velux supplied the suntunnel with the Lovegrove accessory, a device which allows to dimm the daylight.

 The use of suntunnels  will avoid the use of electric lighting during the day, as they will create a sufficient illuminance level  for toilets and entrance area.

ecoBiblioteca update -Project is taking shape!

Good news from Cacica! The construction process of ecoBiblioteca is advancing very quickly. Workers  are constantly digging, measuring, cutting or mounting something, all under the careful direction of  Site Manager PhD. Bogdan Draganescu of Smart&Pepper.

During my first  visit on site, last week,  the northern slope of the roof had been cleared of the asbestos layer and  the new roofing of shingles was starting to be mounted.    Half of the roof shingles on the northern side have been mounted over a period of just one day  by a team of very hard-working craftsmen from nearby.

The roof was extended with an overhang of 30 centimeters from the first rafter, in order to protect the walls from the rain, and a deck was added beneath for the same purposes. We’ve decided to salvage and reuse all the materials from the former storage room that was deconstructed and so most of the battens that support the shingles are pieces of wood from the old building’s roof that are given a new life.

And, by the way, the shingles are a local opportunity : most people in Cacica buy them in large quantities and keep them stored in the backyard for occasional roof replacements. Most of the time, the shingles just lay there, occupying precious space, so the locals were glad to get rid of them, selling them to the ecoBiblioteca team, who are always happy to promote traditional technologies. It’s a win-win situation!

But that isn’t the only thing the team has done last week. Foundation holes have been dug to support the future porch access area (also in the north). Due to the heavy and frequent rain characteristic to the area, the foundation can’t be made in just one  shot, so the workers dig it piece by piece, by a 1 meter distance between the sections. The holes are then filled with concrete and, after it dries, the next holes are dug and the process repeats until the foundation of the porch is ready.

There was more digging involved in the building’s existing foundation area, that needs to be insulated. The existing foundation is completely made of stone blocks. Due to its irregularities,  underground insulation can’t be attached, therefore the team had to obtain a plane surface by pouring about 7-10 centimeters of cement in front of the stones. On this vertical surface, the thermal insulation will be added.

Finding new uses for old things is important to the ecoBiblioteca team, so all of the material that came from the deconstruction of some parts of the building was separetely stored, in order to be reused locally. For instance, the mix of rubble and brick fragments will become part of the base of a local road, that the mayor is building, along with the 5 tonne of debris that used to be the building’s ceiling.

By the time this post was added, I received news of the ecoBiblioteca banner being installed on site. It’s a busy weekend for Cacica, with the upcoming pilgrimage to the Cathedral next to our site, related to Saint Mary on the 15th of August. Hope our project will also become one of the visitors’ interesting things to see here.

Glad to be a part of this team,

Arch.Luiza Hanc

________________

The construction works of the green library renovation project have gotten underway with site preparation and the beginning of the “deconstruction” of an adjoining, derelict building and the organization of its usable materials to be integrated into the renovated building and the surrounding landscaping.

Project Site Manager Bogdan Draganescu of Smart & Pepper Consulting ensured the site was prepared to exceed the required Health and Safety regulations as well as to ensure the construction activity on the site will not cause harm to the surrounding ecology.   The construction team was briefed on the requirements of the “Living Building Challenge” standard which included carefully categorizing and storing of reusable materials and management of hazardous waste.   The standard requires almost all of the construction waste to be diverted from landfills.

For more information about the project, see:  or contact Timea Paal, ecoBiblioteca’s Project Manager for RoGBC.
