Owner approach of sustainability

Residential building consisting of five basements of garage, ground floor for commercial premises, 9 floors dedicated to 74 homes and a floor under cover where the technical rooms of the building are located. Given the sustainable character that the Cooperative wants to give to its building, they have decided to go several steps beyond the norm and obtain a GREEN Environmental Certification, which recognizes its criteria and guarantees its respect for the Environment, giving visibility to the good practices carried out during the construction. Among the main conditions to be respected, and totally unavoidable, is the improvement of the quality of life of the users while maintaining the environmental values, all without increasing construction costs. This project involves the construction of homes with noble appearance, durable and functional finishes and high energy efficiency (with Energy Certification type A), and is about to become the first building of housing with GREEN Environmental Certification in the Galician Autonomous Community.

Architectural description

The Galician Cooperative Society of Parks Parque Ofimático aims to build a high quality building, durable and requiring low maintenance, with maximum energy efficiency and showing great respect for the environment. For this reason, it decided to go several steps beyond the norm and obtain a GREEN Environmental Certification, which is currently in process, and that it will recognize its criteria and guarantee its respect for the Environment, giving visibility to the good practices carried out. This project involves the construction of homes with a noble appearance, durable and functional finishes and a high energy efficiency (with Energy Certification type A), and is about to become the first building of housing with GREEN Environmental Certification in the Galician Autonomous Community .

Systems

Heating system :
• Heat pump
• Low temperature floor heating
• Solar thermal
Hot water system :
• Heat pump
• Solar Thermal
Cooling system :
• No cooling system
Ventilation system :
• Single flow
Renewable systems :

Solutions enhancing nature free gains :

The architectural design is based on an environmental strategy based on the capitalization of the benefits of solar radiation and prevailing winds. On the resulting volume of building, an eave system is projected onto the façades

Smart Building

BMS :

All homes have a home automation system that allows both the management of alarms and the management of the operation of blinds, lighting and heating using tablet, pc or telephone with internet connection. They also have thermal counters

GHG emissions

• GHG in use : 2,30 KgCO₂/m²/year
Methodology used :

Spanish Royal Decree: 47/2007

• Building lifetime : 50,00 year(s)

Life Cycle Analysis

Indicators contemplated: Incorporated energy (57,363,474.82 MJ) and global warming potential - equivalent CO2 emissions (4,976.80).

Water management

• Consumption from water network : 13 828,00 m³

Water Consumption/m2 : 1.01

Water Consumption/Dwelling : 186.86


The building has timed faucets of low flow and cisterns of double discharge to reduce the consumption of inner water as much as possible.

Comfort

Health & comfort : 100% of the houses are protected of the exterior views. 50% of homes are entitled to the sun, so they get direct sunshine in the areas inhabited during the central hours of the day throughout the year. And 12% of the homes have private open spaces through terraces.

Measured thermal comfort : Temperatura interior en invierno: 21°C - Valor de aceptabilidad: 90%
