EnviHUT Tasks

Tasks

  •  – Realization of the experimental object using environmentally friendly materials, with emphasis put onto the application of local resources and renewable energy sources.
  •  – Creation of a cost-effective construction for practical teaching within the grounds of the university.
  •  – Incorporation of the previous goals to an actually habitable building in a way that the building physical measurements would be as realistic as possible.
  •  – And lastly to make the general public and professionals to understand the concept behind the building.

Site description

EnviHUT is part of the external testing grounds of AdMaS Research Centre of Brno University of Technology. AdMaS research centre is located on the outskirts of Brno (Czech Republic) near the university’s dormitories. The subject of the competition, EnviHUT, is located in the heart of the entire complex on a terraced area and is surrounded by four industrial building objects. The experimental grounds are to be used by doctoral students of the faculty and by the employees of the research centre. EnviHUT is directly visible from the main gate through a small scale alley between two of the industrial buildings.

Designing with the Natural Surroundings

Thanks to active photosynthesis of green roofs, EnviHUT has a progressive carbon footprint. The utilization of recycled materials and environmental friendly production of electricity early on reduces the absolute base value of underlying carbon footprint. One of the experimental roof compositions installed combines the advantages of bio-diverse green roofs with traditional Nordic steep roof variants. The later of the two were studied by the authors in Iceland in the years of 2013 and 2014. Later on with time this section should acquire the character of surrounding environment and take on appearance of the surrounding ecosystem. Whether the experiment will be successful or not will be shown by the comparison of insects inhabiting the roof and the surroundings.

The monitoring and testing of bio-diverse roofs is focused on the determination of observed physical parameters and on the comparison of green roof variations. The aim is to find a link between these variations. The target is to present a cheaper variant of a green roof designed especially for smaller objects with a gable roof. Thanks to the results of this research the number of implementation of bio-diverse green roofs could increase into the future, which would effect the entire urban concept of cities more than the individual installations of extensive green roofs.

Climate Protection

The base design of EnviHUT implements several features of Northern European buildings, caused by the research of effects of aggressive boundary conditions on EnviHUT. Among these especially wind turned out to be beneficial. Because of wind the quality of ventilation of air within the cavity increased by leaps. The installation of longitudinal ventilation joints in the roof structure in combination with the automatically closing inlet openings near the bottom creates a balance between the ventilation of condensed water and thermal insulating properties. Until now the theory behind this concept was only simulated and has not been experimentally verified yet. With the least energy consumption possible the system might combine the advantages of single and double layered flat green roofs.
