Energía en Edificación

TECNALIA is working on the EnPROVE project, where  the main objective of developing a decision support tool for energy-efficient building renovation. Target building is audited for a given period, which is used to predict energy consumptions (lighting and HVAC) for the whole year, identifying renovation alternatives and evaluating  energy savings and costs, among other factors.

The novelty resides in the fact that prediction is very dependent on how the building is being used  (usage, occupation and consumption patterns), so it is specific for each building.

First public newsletter of the project:

TECNALIA works in the office of the future, a wireless working place where energy efficiency is a priority. “The energy savings of 10 million office workers turning off unneeded lights for 30 minutes a day is enough to light four million square meters.”

With this objective TECNALIA develops new concepts for intelligent office furniture, in order to manage the lighting adapted to the needs of each working place which takes into account the natural lighting. Furniture adapted to technology and environmentally friendly, as well as healthy and comfortable.

International Patent granted to TECNALIA: “Solar passive collector module for building envelopes” for energy refurbishment of envelopes.

The evaluation of the international search report issued by the European Patent Office for PCT international patent application named “PASSIVE SOLAR COLLECTOR MODULE FOR BUILDING ENCLOSURES” (“Passive solar collector module for building facades”) was highly satisfactory, recognizing that application reports to novelty and inventive step regarding state of the art. In the middle of this year, Tecnalia Construction Unit has received International Publication Number WO 2011/080356 A1 by the World Intellectual Property Organization.

The present invention falls within the technical field of passive solar collectors with ventilation systems for exterior walls of buildings. A passive solar collector module comprising a transparent panel and a heat absorbing panel, spaced by an air chamber and mounted on a perimeter frame; a top air duct communicating with the air near the ceiling area of building a plant; a lower air duct communicating with the air near the floor area of a floor of the building, a room air inlet at the bottom of the module and a heated air outlet at the top of module, a first air routing system operable so that, in a first position sealing the outlet and a second position closes the upper airway, a second air routing system operable so that, in a first position closes the lower air duct, in a second position closes the air flow to the air outlet and in third position, it closes the lower air duct or the flow of air to the air outlet.

This system is primarily intended for energy refurbishment of existing buildings, also adaptable also to new construction, and incorporates innovations such as the incorporation of phase change material (PCM) as a thermal energy capture/ storage element and a ventilation management system powered by an intelligent controller capable of reducing the final consumption of winter heating and even cooling consumption in the summer months.

Different ways of operating the passive solar collector module

Kubik, our test building keeps changing. Since its opening in spring 2010, it’s been aimed at a continuous change to serve every new test for each client. And it has kept changing ever since.

In the past year and a half, two if it´s façades have been modified, some windows have disappeared I the South façade, and shading devices have been modified in the lower floor. HVAC systems have been modified tin the lower floor, internal partitionning has been performed in the 2nd floor, and several other small modifications.

And it will keep on changing.

In the frame of the Smart Cities World Conference held in Barcelona from 29th November to 1st December, José María Campos as Head of Energy Efficient Built Environment of TECNALIA presented our methodology in the design and development of Smart Buildings and Cities, tackling energy efficiency and integration of Renewable Energies as a main objective.

The design of very low energy buildings is a very complex multi-variable dynamic process that requires a holistic and systematic approach to end-up with a much optimized solution. TECNALIA has developed a methodology to achieve such target in the most efficient way, which was presented at the conference.

In the contrary, the energy design of districts and cities lacks of reliable tools that enable a quick and detailed analysis of the different options in the urban design. An integrative urban design requires powerful tools to enable professionals come to the best design option in the most efficient way. TECNALIA has developed and validated a tool to provide professionals with this support.
