Building and energy

The reduction of the building energy demand as well as the increasing of renewables are the major objectives of the ongoing energy transition. Used in synergies, it will permit on mid-term a dramatic reduction of the primary energy consumption with fossil origin while maintening the confort conditions. The concept that will minimize the global carbon footprint with the energy retrofit, will use the best heating system adapted to the situation and will harvest the solar energy of the building. In an integrated design approach, in collaboration with the owner, the architect, engineering offices and sub-contractors, Tecphy offers its expertise for the following missions :

• Audit énergétique : certificat CECB et rapport de conseil CECB-Plus
• Global energy study
• Building physics calculation Pre-dimensioning systems
• Energy calculation forms
• Permitting (mise à l’enquête)
• Writing specifications and finding subconstractors
• Calculation and choice of final systems
• Acceptance of installation
• Operational optimizations
• Monitoring

Architecture and energy integration

Passive building permits to reduce consumption and the architectural integration of renewables will gather performance and aestehetic harvesting at maximum the production potential : solar panels and PV panels on facades, integrated in bodyguards, shadowing systems or simply on the roof in an integrated way (BIPV). Tecphy will support you in the integration of renewable as well as the building domotics : heating-cooling, ventilation, natural ventilation with active aperture systems, solar protection and artificial ight. To answer to the requirements of  the reducing the carbon foot print, Tecphy calculates the environmental indicators associated to the solutions considering both embodied energy spent energy with the buiding under operation (Software DesignBuilder and internal tools).

Self-consumption

Tecphy will support you in the design and the realisation of the electrical microgrid of your building, comprising the PV installation, the storage unit and the algorithms driving the consumers. The optimum management of the power flows between the producers, consumers and the storage unit will allow you to secure, with an attractive return on investment, the partial up to the complete yearly self-sufficiency. Priority loads, suh as lightening or cold production can be secured in case of network defect : loads will be fed in this case by the battery, the fuel cell and /or PV panels.

Energy Management Algorithm

With a Building equipped with PV panels, an algorithm  drives the power flows in the building micro-grid to target specific objectives such as to maximize self-consumption and therefore reduce purchased daily electricity from the grid. A thermal algorithm of the building permits to optimize the HVAC system as well as the natural ventilation. To achieve these objectives, the algorithm will use the production and the consumption forecast that can be provided by SmarSolar over a forecast period from 24 to 72 hours.
