Multi-family building in El Carmel 

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.

Description

Passivhaus consultancy for an elderly people residence located in Barcelona capital, designed by Genars architecture studio and developed by FIATC Seguros through FIATC Residencias (Inverfiatc). This 6575 m2 building is in the process of Passivhaus Classic certification.

Praxis has delivered the PHPP modelling, design of the thermal envelope and airtight layer, advice on low-impact materials, and analysis and optimisation of thermal bridges and construction details.

We’ve also undertaken a thermodynamic and daylighting study of the building, using DesignBuilder (EnergyPlus & Radiance), to assess natural light levels and analyse the risk of summer overheating.

Our work has also included an audit of the mechanical and electrical systems, with proposals for improvements and compliance with the Passivhaus standard, to ensure efficient operation and low maintenance costs. Praxis has also undertaken the Blower Door testing and on-site Passivhaus supervision and quality control.
