La Borda Nova, Andorra: Multifamily Passivhaus

Passivhaus Certification, thermal bridge calculations

Description

Public development with 44 social housing units, designed by architects Pau Iglesias Rodríguez and Jacint Gil Rodríguez, with Oliver Style of Praxis Resilient Buildings as Passivhaus certifier. The building is located in the city of Andorra La Vella, the capital city of Andorra.

The project has a treated floor area of 3350 m2 and includes 228 parking places, ground floor commercial premises and a roof garden.

Alongside the certification of the building, Praxis is carrying out Passivhaus component certification of the Butech (Porcelanosa) prefabricated construction system which is being installed on the façade of the building.

Description

Energy consultancy and M&E design for a wine cellar and tasting room in the Priorat region, Tarragona, designed by architect Èlia Vaqué.

The winery consists of two modules, one underground, where wine is aged, and another above ground, where tastings are held: a total of 290 m2 gross floor area.

Praxis has undertaken a thermodynamic and daylighting study of the buildings, using DesignBuilder (EnergyPlus & Radiance), assessing temperature and relative humidity conditions in the wine cellar and analysing the risk of summer overheating in the tasting room. The results have been used in the design of the thermal envelope. We’ve also designed the M & E systems: mechanical ventilation with heat recovery, space heating and cooling, hot water production, and off-grid solar PV with batteries and backup generator.

Multi-family building in El Carmel

Energy consultancy

Description

Energy consultancy for a multi-family building in El Carmel, a neighbourhood in the north of Barcelona, designed by Vora Arquitectura studio.

This 544 m2 building, has a ground floor and 6 upper floors, on a sloped site in Mount Carmel. Each floor has one or two apartments, with a total of 7 units.

Praxis has delivered the thermodynamic simulation in Design Builder (EnergyPlus), focusing on the analysis and optimization of passive systems: analysis of solar gains, optimization of thermal insulation and bioclimatic buffer zone balcony spaces. The modelling helped us deliver the thermal and airtight envelope specification, window and shading systems specification, including a study of the impact of heat recovery in the ventilation system on energy demands.

Praxis also undertook an embodied energy study, comparing the carbon footprint and costs of different construction assemblies for external walls, with the aim of choosing an economically viable, energy efficient and sustainable solution.
