Energy Efficiency in the Building Sector: a Sustainable Future

EnEf è un progetto transnazionale della durata di due anni che mira a promuovere l’efficienza energetica negli edifici, alleviando i gap di conoscenza degli imprenditori e manager delle imprese edili. Obiettivo specifico è quello di sviluppare metodologie e moduli di formazione  inediti sull’efficienza energetica nell’edilizia, che tengano conto degli agli standard europei in materia di formazione.
Per raggiungere tale obiettivo il progetto darà vita ad un piano di formazione innovativo e accessibile attraverso una piattaforma di apprendimento a distanza, arricchita con strumenti di simulazione 3D e buone pratiche del settore in questione.
Il gruppo target del progetto è costituito da imprenditori e manager di imprese edili con un massimo di 50 dipendenti, ovvero la grande maggioranza delle imprese del settore costruzioni, uno dei più ampi e dinamici dell’economia europea.
Nella prima fase del progetto, partito a Novembre 2010 è stata condotta un’ampia ed estesa analisi delle carenze dei sistemi di formazione esistenti e dei bisogni formativi del settore in merito all’efficienza energetica;
Il secondo step è consistito nello sviluppo dei materiali di formazione sulla base delle esigenze delle imprese;
Nell’ultima fase, dal 1° Giugno 2012 a Settembre 2012 i materiali e il percorso sviluppati nell’ambito del progetto saranno sottoposti ad un test pilota in 7 diversi paesi europei.

Desigo V5: Innovations from Siemens increase building efficiency
The Siemens Building Technologies Division has introduced version 5 of its Desigo building automation system. Its innovative products such as Total Room Automation as well as efficiency features, like RoomOptiControl and Eco Monitoring, give building operators and users an active role in energy management, leading to permanent reductions in energy and maintenance costs.
A state-of-the-art building automation system is always optimized for energy-efficient operation. However, these optimized settings may start to drift over time. One of the underlying causes is often a lack of transparency for users who simply don't know how the setpoint changes they make can impact energy consumption. This is particularly true for air-conditioned rooms which are also equipped with lighting and sun protection controls. The new version of Desigo keeps room users and building operators apprised of the building's efficiency status. Feedback to users is given using the innovative Green Leaf display, adapted to the expertise and control options of each user group. The system makes it possible to change settings if needed to restore optimal energy efficiency. A study by Technische Universität München (TUM) indicates that by actively involving operators and users in the energy management of a building, energy consumption can be reduced by up to 25% without affecting comfort.
Total Room Automation offers energy savings without reducing comfort
The open, programmable room automation range Desigo Total Room Automation (TRA) is a holistic solution encompassing the HVAC, lighting and shading disciplines. Desigo TRA uses an innovative efficience feature called RoomOptiControl. It automatically detects unnecessary energy consumption in the room and notifies users by changing the color of the Green Leaf icon on the QMX3 room control unit: If room operations are energy efficient, this icon is green. If settings made by a room user lead to unnecessary energy consumption, the icon turns red. To reset room control to energy efficient operation, the user simply presses the display and the Green Leaf icon returns to green.
Using BACnet/IP, PXC3 room automation stations—also part of the TRA package—are integrated seamlessly into the PX automation level with its primary systems (heating generators, HVAC main units and cooling generators). The primary systems are controlled directly through the demand signals from the rooms. This means that the primary systems are only turned on if needed and their operation is adjusted so it meets the room requirements without exceeding them. One room automation station can cover multiple rooms. TRA offers complete integration of KNX, DALI and EnOcean devices; existing or new sensors and actuators from Siemens can be incorporated as well.
Eco Monitoring to reduce energy consumption and wear
Eco Monitoring is another innovative efficiency feature of Desigo. It monitors ongoing operations of HVAC systems based on energy-related quality condition indicators such as readings from temperature, humidity and pressure sensors, runtime, switching behavior and operational performance of the systems. Should deviations from the target state, inefficient operations or increased energy consumption occur, the building operator is notified via the Green Leaf display on the Desigo Insight management station. Current and future international standards (such as EN 15323:2007) require such a feature in order to optimize building operations over the long term.
Desigo Eco Monitoring not only helps optimize energy consumption, it also reduces wear. Thanks to its dynamic behavior and timely reporting, the Eco Monitoring feature recognizes unfavorable system operations early on, allowing operators to intervene immediately before any negative impact occurs. If desired, operators can choose to be notified of unusual events via text messaging (SMS), fax or e-mail.
Expanded networking of the automation level
Starting with version 5, Desigo also offers expanded end-to-end networking of the automation level. Enhanced support for communications standards ensures efficient system integration. The PXC series of compact automation stations has a higher number of universal inputs/outputs, which makes them much more flexible. To protect existing investments, different device generations, such as PTM and TX I/O modules and RXC room controllers, can be used in parallel on the same PX automation station.
