BIURU PASTATO MIKROKLIMATO SISTEMU VEIKIMO PARAMETRU ITAKA ENERGIJOS POREIKIAMS/THE IMPACT OF AN OFFICE INDOOR CLIMATE SYSTEM PERFORMANCE PARAMETERS ON ENERGY CONSUMPTION

Europos Sajungoje keliami tikslai, skatinantys energijos vartojimo efektyvumo didinima. Viena didžiausiu energijos vartojimo mažinimo potencialu turi pastatu sektorius. Šiame straipsnyje analizuojama, kokia itaka energijos poreikiams daro pastato mikroklimato sistemu veikimo parametru keitimas pastato valdymo sistemoje. Tyrimas atliekamas naudojant dinaminio energinio modeliavimo programa DesignBuilder. Tyrimo objekto modelis sukurtas pagal realaus administracines paskirties pastato projektine dokumentacija bei remiantis pastato valdymo sistemos fiksuojamais duomenimis. Sukurtame modelyje keiciami mikroklimato sistemu komponentu darbo režimai ir parametrai. Atlikus pakeitimus atliekamas ivairiu sistemu valdymo alternatyvu modeliavimas. Rezultatai lyginami tarpusavyje, analizuojama skirtingu parametru itaka pastato energijos poreikiams. Tyrimo metu nustatyta, kad, tinkamai suderinus mikroklimato sistemu veikimo parametrus, galima tiketis 26% šilumos ir 7% vesos sanaudu sumažejimo, kuris nedaro neigiamo poveikio patalpose esanciu žmoniu komfortui.

This article presents the impact of changing the operating parameters of a building's indoor climate systems on a building's management system. The study is performed using the dynamic energy modelling program DesignBuilder. The created dynamic energy model is based on the documentation of an actual administrative building and the data recorded by the building management system. The developed model changes the operating modes and parameters of the components of microclimate systems. After the changes, simulations are performed to obtain new results for the building's energy needs. These results are compared, and the impact of different parameters on energy consumption is analyzed. The study found that a proper setting of indoor climate performance can lead to a 26% reduction in heat and a 7% reduction in cooling costs, which does not adversely affect the comfort of the people. Keywords: indoor climate systems, energy consumption, DesignBuilder, building dynamic energy modelling.
