Sustainability consulting

After studying the initial conditions: (climate, orientation, sunlight, winds…), it is possible to draw conclusions about the key factors to consider and propose the most appropriate strategies for an eco-efficient behavior. We develop previous studies of building sustainability, and we collaborate in the design phases of projects in order to improve the efficiency by passive and active measures implementation. 

 

THERMAL SIMULATION

The thermal simulation is a powerfull tool to predict the thermal behavior expected in a building, by a calculation based on a dynamic model. After entering the climatic conditions, volume and constructive definition, it is possible to model the performance of a building under different passive and active strategies: modification of the envelope, natural or forced ventilation, singular solutions, etc. 

This iterative procedure allows confirming or correcting project approaches, and afterwards optimizing the building design to use less energy; it should also facilitate communication to the customer of environmental and economic objectives achieved. We work with ENERGY PLUS, a whole building energy simulation program developed by DOE (Department of Energy, United States), widely recognized and used internationally. 

SOLAR SIMULATION

Simulation of sun path, solar radiation, shadows and reflections allows knowing the influence of sun and obstructions on a building or urban space, and thus the number of hours with direct solar incidence on a facade or window, the most appropriate orientation for a building, the most appropriate orientation for an urban development, etc. We work both with manual models (solar charts, calculating shadow mask, shading design) for simple estimates and with ECOTEC for complex simulations.   

DAYLIGHTING SIMULATION

Daylighting simulation allows to know the natural lighting levels to be obtained inside a space we are designing (an office, a playground, etc.). Therefore, we should adopt strategies to improve natural lighting conditions (depth of the rooms, reflections, obstacles, etc.). 

We work with ECOTEC, which enable calculation of daylight factors and illuminance levels at any point in the model. 

LIFE CYCLE ASSESSMENT

The life cycle analysis (LCA) of a building is a technique to identify the environmental impacts over the life of the building, by quantifying flows entering and leaving the system, and the environmental impacts associated with these flows. Considering the environmental impacts from the manufacturing phase of materials to the deconstruction of the building (“cradle to grave”), provides a holistic view of the building process.  Provides a rigorous comparison of the impacts associated with each solution, contributing to a responsible choice of strategies.
