Life Zero Energy Mod at EHEC

Life Zero Energy Mod was presented at EHEC 2022.

The European Hydrogen Energy Conference (EHEC) is the European reference conference in the field of hydrogen energy.

The EHEC took place from May 18 to 20, 2022 in Madrid. EHEC is identified in the Spanish Hydrogen Roadmap 2020 as one of the measures to position Spain as a reference for these technologies in Europe.

During the event, our colleague Carlos Arié, Innovation Technician of the Aragon Hydrogen Foundation, presented the objectives of the project, as well as its main challenges.


Self-sufficient living module at CONTART2022

Self-sufficient living module at CONTART2022. With Life Zero Energy Mod was presented the commitment to transportable modules that incorporate renewable energy sources.
The exhibition took place at the IX International Convention of Technical Architecture in Toledo.
Our partner, B+HAUS, represented by Roberto Higuero Artigas, made a presentation in the “scientific communications” session. It was focused on the objectives and achievements of the Zero Energy Mod project.

Zero emissions

At the beginning, Higuero highlighted that the ZEROENERGYMOD project achieves zero impact on emissions. Energy storage through hydrogen and photovoltaic and wind energy production makes this possible.

He added that the project is 55% financed by LIFE funds, the rest being contributed by the participating companies. The investment in the research amounts to one million euros.

Later in the scientific communications session, he answered different questions:

-What are we going to achieve?
-Thanks to the Life Zero Energy Mod project, savings in energy consumption of at least 85% will be achieved with respect to current housing modules, guaranteeing maximum indoor air quality.

-How are we going to achieve this?
-We are building a prototype called ZEROENERGYMOD which consists of two parts. The first is the ENERMOD module that generates 2 types of renewable energy (wind and solar) and two types of energy storage (batteries and hydrogen storage) to cover the energy needs of the habitable module. The second is the PASSIVMOD module, which is a living space designed to offer maximum comfort to the user at the lowest energy cost, built under the PassivHaus standard.

-Where and when did the project start?
-The project started in June 2020. The construction of ZEROENERGYMOD began during the first year of work.

In this project we will move to 3 locations where the Spanish Army operates. Locations chosen for the project due to their geographical, operational and climatological characteristics. CENAD SAN GREGORIO – Zaragoza, Aldazi Base Camp – Latvia and Gabriel de Castilla Base in Deception Island – Antarctic Continent.

Technical benefits: Reduction of assembly time to three days. Maximum thermal comfort, energy savings and emissions reduction while maintaining maximum flexibility in its applications.

Also, the project adapts to the specific regulations for the design of buildings under the Passivhaus standard, as well as to the regulatory requirements of NATO and maritime and air transport standards.

Project partners: B+Haus Arquitectura eficiente SL, CUD – Centro Universitario de la Defensa, Fundación para el desarrollo de las nuevas tecnologías del Hidrógeno en Aragón, and the company ARPA equipos móviles de campaña.


Life monitors Zero Energy Mod

Zero Energy Mod is monitored by Life as part of the team’s annual visit.

The LIFE Program is the EU’s funding instrument for environment and climate action.
The project monitoring team is part of the external LIFE project team, contracted by the European Climate, Infrastructure and Environment Executive Agency (CINEA) as external assistance.

The task of the monitor is to act as a liaison between CINEA and the consortium partners, to evaluate the progress of the project and to serve as a point of contact to try to resolve all the doubts and questions that may arise for the partners during the life of the project.
To carry out this task, in addition to periodic remote monitoring, the monitoring team visits the project in person at least once a year.

In this case, this visit coincided with the middle of the Zero Energy Mod project and the transition between the design/construction and demonstration phases, so there was great interest in visiting the module installed in the first demo site.


The European Climate, Infrastructure and Environment Executive Agency (CINEA) aims to help stakeholders implement the European Green Pact through high quality program management, which helps to deliver projects beneficial to decarbonization and sustainable growth.

Visit to the prototype at St George’s Base

On 11th April all project partners met to supervise the correct installation of the prototype habitable module at the San Jorge Base. This easy to install and transport space, based on the PassivHaus standard, incorporates renewable energy sources. This will achieve an 85% reduction in energy consumption compared to the solutions currently used. This module will be transported for use by the Army’s Antarctic Campaign. The Antarctic Campaign is carried out annually at the Spanish Antarctic Base “Gabriel de Castilla”, located on Deception Island (South Shetland Islands Archipelago) and in other places in the Antarctic territory to be determined, all in support of the Ministry of Science and Innovation and the Spanish Polar Committee (SPC) for the development of Antarctic research.


We participate in the Spanish Passivhaus Conference

The main objective of the Spanish Passivhaus Conference, organised by PEP annually, is to provide a meeting forum for the whole construction sector, technicians, administration, manufacturers and in general all the agents involved in the whole process of design, promotion, construction and use of buildings.

The authors’ paper was presented. Beatriz Rodríguez Soria and Miguel Ángel García García from CUD and Carlos Navarro Gutiérrez from BHAUS, all of them members of our consortium. The work presented detected the need to reduce the dependence on fossil fuels as well as CO2 emissions in the military Bases and Barracks of the European Armed Forces (BAEs) and shows how the ZERO ENERGYMOD project of the LIFE funding programme is an optimal solution.

As a result of applying the design conditions, a design has been developed based on 20-foot containers with a rigid stackable chassis structure, modified with respect to those currently available in order to avoid thermal bridges. The HIGH CUBE model has been selected to have a false ceiling.

It has a base insulation in the removable panels of the chassis of 10 cm of high density wool and double tongue and groove. On the inside, another layer of the same panels has been installed and on the outside, 30 cm thick skins of high density wool with an exterior stainless steel finish.

The project LIFE ZERO ENERGYMOD awarded at the II Gala de la Edificación de Aragón

On Friday 12th November, the Zaragoza Conference Centre hosted the second edition of the Aragonese Building Gala, organised by the Official Association of Quantity Surveyors and Technical Architects of the Aragonese capital and the rest of the building industry. At the event, the awards for this important sector were presented. The awards were based on three main themes: sustainability, innovation and refurbishment as the major needs of our cities. The award for the best innovation project applied to building went to LIFE ZERO ENERGYMOD, our project financed by the European LIFE programme.

This award is a great satisfaction for the consortium and especially for BHAUS as it recognises the effort made in the design of this living space with minimum energy consumption in any location and climate. The fact that all the entities participating in the consortium are Aragonese also shows the region’s capacity to carry out innovative projects that combine energy management and habitability. The germ of the project idea arose from the collaboration that CUD and FHa were carrying out to improve habitability and energy management at the Gabriel de Castilla Antarctic base. This idea was developed by BHAUS applying PassivHaus standards to achieve minimum energy consumption, and finally ARPA contributed its proven experience in the construction of mobile equipment, as well as its capacity for deployment in any location.
The president of the Zaragoza Association of Technical Architects, Rafael Gracia, highlighted during the gala: “the building sector is at a very exciting time, as users are beginning to be aware of the great benefits that new homes have and it is also expected that the aid from European funds will greatly boost the rehabilitation of buildings”.
