Neinor Pintor Alsamora Residential Building

Barcelona, Spain

Strategies implemented

Purposeful analysis of bioclimatic and environmental aspects
Objective: to achieve maximum comfort with minimum energy consumption

This project has an energy certification rating A (final energy consumption 7.81 kWh/m2 year and CO2 emissions: 2.59 kg CO2/m2 year).

A BREEAM certificate: Good rating with the following scores:

• Management: 78%
• Energy: 73%
• Transportation: 80%
• Waste: 63%
• Land use: 64%

Data to highlight:

• Double orientation homes are proposed.
• The response of the two main facades is designed according to their orientation.
• The façade system is ventilated, built dry, with factory production and simple on-site assembly. This way, resources, waste and energy consumption are optimized.
• The composition of the façade makes it possible to reduce the demands for cooling and heating, as well as to increase the inertia and radiation of the interior.
• A high-efficiency aerothermal system is used to allow high energy savings. Due to its characteristics, this system makes it possible to take advantage of the energy from the air.
• The building has native vegetation, reducing the need for irrigation and, therefore, reflecting in water savings.
• The location of the building facing a public garden allows benefiting from the good climatic behaviour of vegetation and its evaporation, in benefit of greater urban and domestic comfort.
• The final energy consumption represents a saving of more than 60% compared to the average for buildings of its type, as well as a reduction in CO2 emissions of 60% better than the average.
• Its use and maintenance are managed in a way that reduces its environmental impact through strategies such as a policy of purchasing sustainable cleaning products and the maintenance of facilities to protect them and extend their useful life.
• A thermo-solar system allows the production of DHW for the building through this renewable source.
