For a four-story residential timber building using traditional reinforced concrete materials and CLT panels, we designed a system for complete protection against increased moisture and water leakage. This is because wood is used not only as a load-bearing structure but also as a visual material for selected interior partitions on all floors.
Sustainability in construction
The building will use 1,600 m³ of timber, reducing the total volume of concrete used by up to half compared to conventional construction methods. SENZOMATIC will also contribute to the sustainability of the building, as the early detection of emerging moisture or small to large water leaks will significantly extend its lifetime.
Moisture protection design
We have divided the protection of the building into two parts - monitoring water leakage from the green roof and monitoring the moisture status of the wooden structure in the housing units. Due to their typification, it was possible to fit them all with the same set of sensors placed in identical locations. On the ground floor, we installed MHT sensors monitoring humidity and temperature in the wood under the showers and the utility room under the floor in place of the washer and dryer. We also remembered the frames under the patio entrance door, where moisture condensation and seepage into the wood often occurs due to temperature differences between the interior and exterior. We placed the same sensors in the above-ground apartments, except that the MHT sensor was placed in the door's frame to the balcony instead of the sliding patio door.
Retention tank issues
The flat roof of the residence with greenery is adapted to capture rainfall into storage and retention tanks with a total volume of 135,000 liters. This water is then used to irrigate the vegetation in the common areas. Despite the many benefits, green roofs pose an increased risk of water leakage into the building due to micro-cracks in the insulation, blocked drains, or distribution joints. To ensure that this area is monitored, we decided to use special HT-R sensors to detect both increased moisture and the presence of water and pinpoint the source of the problem.
