The New European Bauhaus initiative connects the European Green Deal to our living spaces. It calls on all Europeans to imagine and build together a sustainable and inclusive future that is beautiful for our eyes, minds, and souls.
The New European Bauhaus wants form to follow planet. The goal is to create a design movement integrating three dimensions: sustainability (including circularity), quality of experience (including aesthetics) and inclusion (including affordability). Showing that creativity is in finding affordable, inclusive and attractive solutions for our climate challenges.
This initiative is a creative and interdisciplinary movement in the making, and you can be part of it. The New European Bauhaus team will present the initiative and the opportunities to contribute to it. Follow this link to join the live stream on the 11th March 2021 and ask your questions.
Climate change is a serious global issue. The use of fossil fuels as our main source of energy generation is largely contributing to the problem. Human activity is releasing billions of tonnes of carbon dioxide (CO2) emissions into the earth’s atmosphere and adding substantially to the greenhouse effect.
Buildings and construction play a major part, accounting for nearly 40% of energy-related carbon dioxide (CO2) emissions whilst also having a significant impact on our natural habitats.
As architects, we have the ability and responsibility to provide solutions that minimize the climate impact of the structures we design.
Together with our clients, Architects will need to commission and design buildings, cities and infrastructures as indivisible components of a larger, constantly regenerating and self-sustaining system.
The research and technology exist for Architects to begin that transformation now, but what has been lacking is collective will. Recognising this, and as one of the founding signatories of Architects Declare , Isabel Barros Architects are committing to strengthen our working practices to create architecture and urbanism that has a more positive impact on the world around us.
This collective effort seeks to:
Raise awareness of the climate and biodiversity emergencies and the urgent need for action amongst our clients and supply chains.
Advocate for faster change in our industry towards regenerative design practices and a higher Governmental funding priority to support this.
Establish climate and biodiversity mitigation principles as the key measure of our industry’s success: demonstrated through awards, prizes and listings.
Share knowledge and research to that end on an open source basis.
Evaluate all new projects against the aspiration to contribute positively to mitigating climate breakdown, and encourage our clients to adopt this approach.
Upgrade existing buildings for extended use as a more carbon efficient alternative to demolition and new build whenever there is a viable choice.
Include life cycle costing, whole life carbon modelling and post occupancy evaluation as part of our basic scope of work, to reduce both embodied and operational resource use.
Adopt more regenerative design principles in our studios, with the aim of designing architecture and urbanism that goes beyond the standard of net zero carbon in use.
Collaborate with engineers, contractors and clients to further reduce construction waste.
Accelerate the shift to low embodied carbon materials in all our work.
Minimise wasteful use of resources in architecture and urban planning, both in quantum and in detail
The make-up of greenhouse gas emissions differs in Ireland from most other European countries because of the role Ireland plays in supplying meat and dairy products across Europe and the world. Agriculture (largely through methane associated with our herds) makes up 32% of emissions from sectors in Ireland compared to just 11% in the rest of Europe. However, in all other major sectors (Electricity, Buildings, Transport, and Waste Management) we also have a higher carbon footprint per head of population.
Ireland faces a number of challenges in reducing emissions from our buildings. Our homes use 7% more energy than the EU average and emit 58% more carbon dioxide equivalent. Our buildings are 70% reliant on fossil fuels, including oil fired boilers; over 80% of our homes and other buildings assessed for their BER have a rating of C or worse; and the current annual retrofit activity for existing stock is far too limited (approximately 23,000, mainly shallow, retrofits).

We are aware that for everyone working in the construction industry a paradigm shift in our behaviour is required in order to achieve a substantial reduction of the worldwide CO2 emissions. We will do our best to support this shift while encouraging our clients to also adopt this approach.
Isabel Barros Architects in Wexford are committed to face these challenges by fundamentally rethinking the way we design, construct and operate buildings.
As of January 2020 a total of 69 Irish architects/architectural practices have signed the declaration. We hope that many more will join us in making this commitment. Please visit https://ie.architectsdeclare.com/ to join.
We are delighted to have achieved Planning Permission for this fantastic project in Wexford.
The site presents a south-facing slope offering open views in a rural landscape. There are large fields surrounding the site, the fields are delineated by native hedges and trees. A number of neighbouring farmyards are also part of the place.
There is a pattern of materials that is repeated within the area giving it a sense of harmony, these include corrugated metal, rubble stone and white renders.
The south facing aspect of the site offers good access to solar radiation and daylight which are essential for the application of the Passive House standard and passive solar design in general.
The design is strongly
related to the landscape and the place.
The proposed site layout is
inspired by the nearby traditional courtyard farmyards.
The proposal uses a contemporary language based on traditional elements and materials.
Three main volumes inspired by traditional forms create a balanced composition with different heights. The existing rhythm and repetitive pattern of the trees in the northern boundary is reflected in these volumes establishing a strong relationship between the proposed house and the landscape.
The two-storeys volume is conceived to mimic the agricultural buildings in the area. The visual impact is reduced by careful selection of materials that play with mass and weight whilst combining the present with the past.
A simple palette of materials is proposed – white rendered surfaces, notes of rubble stone and grey corrugated metal. The materials aim to connect cultural and local values with a contemporary built environment.
ENERGY PERFORMANCE and SUSTAINABILITY
Passive House Standard The project’s aspirations include to build a low energy sustainable house guided by the Passive House Standard with a view to achieve full certification by the Passive House Institute.
Passive House is the world‘s leading standard in energy efficient construction. The Passive House Standard stands for quality, comfort and energy efficiency.
Passive Houses stay at a comfortable temperature year-round with minimal energy inputs. Such buildings are heated “passively”, making efficient use of the sun, internal heat sources and heat recovery so that conventional heating systems are rendered unnecessary throughout even the coldest of winters. As energy savings equals emissions reductions, the Passive House is a sustainable alternative to conventional construction.
The house is designed and orientated to maximise passive solar gain and natural lighting. The fenestration facing North is minimal to reduce heat loss. Overhangs to shade south-facing windows are also used to reduce overheating during the summer. The house is carefully positioned to avoid the shade caused by the trees in the northern boundary (2 to 8 metres tall).
Building Energy Rating (BER) and Nearly
Zero-Energy Building (nZEB)
The preliminary specifications indicate a Building Energy Rating (BER) of A1 corresponding to an Energy Value of 3.77 KWh/m2/yr. The calculations show an energy performance coefficient (EPC) of 0.024, and a carbon performance coefficient (CPC) of 0.022, which exceeds by far the requirements for a Nearly Zero-Energy Building (nZEB).
Materials and Sustainability
The sustainability strategy also includes the
use of timber products manufactured in Ireland from FSC® certified forests managed by Coillte (MEDITE SMARTPLY/ PROPASSIV
The choice of corrugated metal takes into consideration the overall environmental impact, performance in use, lifetime durability and maintenance requirements. Many corrugated metal products on the market are made of recycled metal and can be recycled again at the end of their use.
The appropriate fabric specification and an airtight and thermal bridge free design are fundamental to achieve the required Passive House certification.
The external envelope will be highly insulated to Passive House Standards to reduce heat losses. Careful detailing will be essential to achieve the required airtightness and avoid thermal bridges. Energy efficient window glazing units and frames are proposed.
The proposed house is a modern interpretation of the traditional courtyard farmyard. The house aims to use a contemporary architectural language inspired by traditional elements and materials of the rural vernacular architecture.
The design creates visual and physical connections with its surroundings. We believe the proposed development acknowledges, respects and enhances the existing character and landscape without creating an adverse visual impact.
Our design approach considers that Passive House buildings do not have to compromise on their design quality. The idea of creating a unique Passive House drawing strongly from the local vernacular forms and materiality has been paramount to this project.
Isabel Barros Architects - Wexford is driven by a passion for creating high quality contemporary Architecture. Our goal is to make good design available to the general public while maintaining a strong focus on the energy efficiency and sustainability of our designs.
