Integrated Design Of Energy Efficient Building

Transcript

PARTICIPANTS Integrated Design of Energy Efficient Building Student: Tadeja Intihar University of Ljubljana, Faculty of Civil and Geodetic Engineering, writing a bachelor‘s degree Local Business Partners: VUPS (Vyzkumny ustav pozemnich staveb) – Building Research Institute Receiving University: Czech Technical University Image 1: Thermal image of old facade of Faculty of Civil Engineering ASSIGNMENT: My first assignment was thermal imaging of Faculty of Civil Engineering in Prague with infra red camera. The measurements were executed four times early in the morning. The occurrence of thermal bridges is the most liable when the temperatures outside are low. It was my first time operating with a thermal camera, I got to know new software and I found out that thermal imaging is a good tool for determining thermal bridges. Since my knowledge in building physics was not sufficient and I did not have much time left with my project, I decided to change my subject of research. My interest remained in the framework of energy efficiency so with the help of my supervisors in Prague the decision was made that I will prepare a construction set for Multipurpose experimental building.

One of the reasons for my decision was also a colleague from our project team who was investigating natural materials. Straw as building material excels in the areas of ease of installation, affordability and energy efficiency. It has exceptional building physic characteristics. It means an opportunity for agriculture as it is basically waste material that the farmers used to burn. It is easily accessible raw material which has a potential for regional economy due to the fact that it is rapidly renewable resource. http://www.santaclaritatransit.com/files/2012/04/tr ansit_construc.jpeg, viewed on 16. 6. 2014 Wall made of straw bales is resistant to burning and pest infestation. Moisture is the greatest enemy of the straw. A great care is required when installing the straw bales. Every effort during design must be made to create a straw bale wall system that will not trap moisture in its interior. The wall needs to be breathable to be protected from the mould. That is why lime or earth plaster should be applied as a finish layer. EVALUATION I cited only few conclusions from our research of that once widely used material. http://www.kzz.hr/sadrzaj/dokumenti/program-planenergetske-ucinkovitosti-2014-2016/energo.jpg, viewed on 16. 6. 2014 European Real Life Learning Lab Alliance http://ecosalon.com/wp-content/uploads/2010/04/strawbale-house.jpg, viewed on 16. 6. 2014 In these 3 months I have experienced working in an interdisciplinary team. Constructing has always been a multidisciplinary work but nowadays we realize even with greater intensity that cooperation of different branches is a necessity if we want an energy efficient building. The cooperation with LBP was an eyeopening experience for me. I have realized that comprehensive and holistic approach in the assessment of energy efficient building is very important. The internship helped at my decision to continue my studies in the field of energy efficiency.
