CUSTOMER CHALLENGE

A Shopping Center The Size of a City

 

BTC City Ljubljana is one of the largest business, shopping, entertainment, recreation and cultural centers in Europe, located just three kilometers from Ljubljana city center and 200m from the Ljubljana ring road. It is considered a must-visit destination by city residents and tourists.

Due to the large number of facilities, wide area, high consumption of electricity, water and heating, BTC’s energy needs are comparable to those of urban centers.

“Energy management is an economic necessity,” says Tomaž Damjan, Energy Manager at BTC City.

In a bid to reduce energy consumption and costs as well as subsequent CO2 emissions, BTC sought to implement an energy management (EM) system for its multi-purpose facilities, such as those used by Smart Cities, and in line with the ISO 50001 standard, aimed at supporting organizations to conserve resources and tackle climate change.

BTC turned to Solvera Lynx to help design their own system to monitor and reduce energy consumption.

Specialists from Solvera Lynx described the key to greater efficiency and energy management coordination was to provide BTC City with “systematic control” over energy consumption.

“Due to the large number of BTC facilities, it was important to control the consumption of individual energy products and monitor consumption by individual end-users,” explained Janez Klančnik, Project and Energy Manager at Solvera Lynx. “BTC needed tools that allowed the easy collection of data, performance analysis and production of automated reports.”

SOLUTION

Applying Smart City Energy Management Tools

 

Solvera Lynx offered an innovative solution for smart energy management (EM) based on wireless LoRaWAN technology. This technology was a better alternative than the classical wired networks due to its long range, unique penetration capabilities, flexibility, easy operation & maintenance, and safe & reliable data transfer.

The solutions included the following steps:

  • Energy consumption monitoring (electricity, heat, natural gas, water)
  • Energy efficiency analysis: key energy KPIs indication and control over electrical energy production
  • Targeted energy performance analyses: targeting energy consumption quantities and costs, especially focusing on the energy consumption of heating and cooling technologies
  • Reduction of energy losses and water leakages
  • Implementation of an alarm system in case of consumption or cost deviations
  • Energy accounting: energy accounting system implementation, building energy consumption benchmarking and analyses of energy costs

 

Due to the large number of BTC facilities, it was important to control the consumption of individual energy products and monitor consumption by individual end-users. With the introduction of the energy management system and energy accounting, BTC gained systematic control over energy consumption through the tools that allow the easy collection of data, performance analysis and production of automated reports. This contributed to greater efficiency and better energy management coordination.

BENEFITS

Steep Reduction in Costs and Consumption

 

Once Solvera Lynx implemented the network, deployed the sensors and connected them to the GemaLogic platform, results were instantly observed.

For example, once the energy data was digitized, energy managers could immediately start monitoring and analysis in real time, and start benchmarking and forecasting. Solvera Lynx EM solutions also include an alarm system that can detect deviations in consumption, such as those caused by a water leakage, alerting the managers for a quick response. EM systems can be improved over time and the easy monitoring leads to taking effective measures to continuously increase BTC City’s efficient consumption of energy.

In fact, after one year of implementing Solvera Lynx’s EM system, BTC City has reduced its energy consumption by 5%. Water leakages have been reduced by up to 90% and energy loss overall caused by water leakage has been reduced by up to 6%. Even more staggering, BTC City has observed that before, water loss was measured at 40%, whereas after the EM solutions were installed, that figure plummeted to 4.5%.

Moreover, early detection of equipment defects, such as in air-conditioning units, has led to replacement of parts that have cut electricity consumption by half!

“The system has paid-off,” said Tomaž Damjan, Energy Manager at BTC City. “We will continue using the GemaLogic energy management platform.”

Meanwhile, the case study has also been a major win for the collaboration between Solvera Lynx and Actility, according to the former’s Toni Žužek.

“We really appreciate the timely and professional support from Actility’s experts,” said Žužek. “They helped meet our needs and strategic milestones, as well as plan and organize more effective sales and marketing activities in order to promote our advanced EM software and hardware solutions.”

Rešitve upravljanja porabe energije že prinašajo koristi večjim industrijskim in stavbnim kompleksom v regiji. Ena najpomembnejših referenc je projekt energetskega managementa v podjetju BTC d.d.

BTC City Ljubljana je eden največjih poslovnih, nakupovalnih, rekreacijskih, zabaviščnih in kulturnih centrov v Evropi. Od središča Ljubljane je oddaljen le 3 km in 200 m od ljubljanskega avtocestnega obroča – kraj, ki ga preprosto morate obiskati. Ustanovljen je bil pred več kot 60 leti in od takrat predstavlja primer inovativnega poslovnega pristopa k trajnostnemu razvoju in učinkovitemu upravljanju porabe energije. Razteza se na 475.000 kvadratnih metrih, vključuje 56 objektov in ne povezuje le tržnih, logističnih in rekreacijskih objektov, temveč tudi dvajset energetskih postaj ter obsežno cestno in energetsko infrastrukturo.

 Poslovni izziv:

Upravljanje tako velikih objektov zahteva porabo izjemno velikih količin energije, ki predstavljajo približno 10 % vseh izdatkov podjetja. Za optimizacijo te izjemno visoke porabe energije je podjetje BTC potrebovalo po meri narejeno rešitev za energetski management.

 Rešitve Solvera Lynx:

Solvera Lynx ponuja nove rešitve za pametno upravljanje porabe energije, ki temelji na brezžični tehnologiji LoRaWAN. Ta tehnologija je boljša izbira v primerjavi s klasičnimi žičnimi omrežji, zahvaljujoč velikemu dosegu, edinstveni prodornosti, prilagodljivosti, preprostemu upravljanju in vzdrževanju ter varnemu in zanesljivemu prenosu podatkov. Za učinkovito povezavo med merilniki in omrežjem je bila vzpostavljena brezžična povezava LoRa. Za izvajanje meritev je bila izbrana inovativna brezžična oprema z dolgim dometom – naprava ComBox.L®. ComBox.L® pošilja podatke programski platformi GemaLogic®, kjer se vsi podatki zberejo, obdelajo in analizirajo.

 Prednosti uvedbe rešitve Solvera Lynx:

  • Konkretni rezultati (optimizacija porabe energije, zmanjÅ¡anje energetskih izgub in uvedba celovitega pregleda nad delovanjem) so se pokazali že nekaj mesecev po uvedbi sistema energetskega upravljanja.
  • Z uvedbo sistema energetskega managementa je podjetje BTC pridobilo možnost sistematičnega nadzora nad porabo energije s pomočjo orodij, ki omogočajo preprosto zbiranje podatkov, analizo učinkovitosti in ustvarjanje avtomatiziranih poročil. Vse to prispeva k večji učinkovitosti in boljÅ¡i koordinaciji pri upravljanju porabe energije.

»Uvedba sistema se je izplačala in zaradi velikih prihrankov, ki smo jih zabeležili, bomo nadaljevali z uporabo platforme GemaLogic za upravljanje porabe energije.« pravi Tomaž Damjan, BTC, d.d.

Prednosti rešitev Solvera Lynx v primerjavi s konkurenco:

Portfelj projektov je resnično izjemen. Za različne projekte so bili pripravljeni pametni merilni sistemi po meri (elektrika, plin, voda, zrak, obnovljivi viri energije), spremljanje količine (rezervoarji/cisterne za gorivo), različne analize (kakovost zraka, temperatura, vlažnost), sledenje/lokalizacija in spremljanje stanja stroja.

Glavne prednosti so inovativne tehnologije in sposobnost prilagajanja naših rešitev za upravljanje porabe energije, tako da ustrezajo edinstvenim potrebam vašega podjetja.
