Abstract [sv]

Energieffektivisering blir en allt viktigare åtgärd på äldre fastigheter i takt med att kostnaden för energi stiger. Att energieffektivisera kan beskrivas som att uppnå samma resultat med mindre energiåtgång, för brukaren resulterar detta i lägre kostnader lagda på inköp av energi och för samhället resulterar detta i en minskad belastning på miljö och klimat. I mitt examensarbete som du håller i din hand har jag undersökt en industrilokal belägen på Teg i Umeå där jag med simuleringsprogrammet IDA ICE simulerat olika energieffektiviseringsåtgärder och hur de skulle påverka byggnadens förbrukning av energi. Åtgärderna som simulerats är: Tilläggsisolering av väggar och tak, byte till FTX-system, byte av fönster samt byte av dörrar och garageportar till mer välisolerade alternativ.

Arbetet består till stor del av litteraturstudie och simuleringsprogrammet där en modell av huset har konstruerats för att efterlikna dess verkliga motsvarighet till så stor grad som möjligt. Efter detta har åtgärderna tillämpats och sedan simulerats för att till sist jämföras med referenshusets simulering.

Resultatet visar att samtliga åtgärder skulle sänka energiförbrukningen av byggnaden i någon mån. Den största besparingen på 49,3 % skulle fås om man byter ventilationssystem medan den minsta besparingen, 0,7 %, fick man genom att byta fönster.

Abstract [en]

Reducing the energy consumption in older buildings is growing to be more important by each passing day as the cost of energy rises and political strides are made to limit the amount of energy used for various purposes. To optimize the use of energy in a building can be described as getting the same end result with a lower amount of spent energy, for the user this is an economic victory as he doesn’t have to spend as much money on heating his building while society gains a reduced impact on the environment and climate. In this thesis that you hold in your hands I have investigated an industrial building located in Teg, Umeå where I utilized the simulation software IDA ICE to simulate the buildings energy usage and the effects of various energy optimization/saving measures if implemented. The measures simulated are: Additional insulation for walls and roof, the switch to a ventilation system with a heat recovery unit, switching to well insulated windows, and switching the doors and garage doors to well insulated units.

The work has mostly been done through studies of literature and IDA ICE where a model of the building has been constructed according to the specifications of the real world counterpart. The results from the various simulations are then compared with each other and the reference case.

The results showed that all energy saving measures would result in a lowered use of energy. The biggest saving was gained from the changing out the ventilation system which resulted in a 49,3 % reduction whilst changing windows only resulted in a 0,7 % reduction.
