Moisture controlled ventilation in dwelling
The project develops modular system solution for demand controlled residential ventilation including highly efficient exhaust hoods
There is developed a modular system of moisture-driven control valves, energy-efficient fume hoods and management systems for homes, hotels, offices, etc. The system must be modular and each module must be used individually, both existing and new buildings. It should be possible for housing associations, etc. stages that could use the moisturecontrolled valves for bathroom renovations later, new hoods mounted in renovation of kitchens and automatic roof fans can be mounted before, during or after renovation or in connection with the fan must be replaced. The humidity-controlled control valve should be designed to operate independently of the other extractors, it must be energy efficient and robust. The goal is that products should be so inexpensive that energy savings can fund replacement with new valves, hoods and automation in a few years. The project is divided into the following work packages: WP 1: Gaining knowledge from previous projects in Denmark, Sweden etc. WP 2: Design and development of new moisture-controlled valve, energy efficient and climatecontrolled hoods and standard automation. WP 3: Testing in laboratory. WP 4: Testing of multi-storey buildings. WP 5: Evaluation. WP 6: Reporting and dissemination. WP 7: Future changes in legislation. WP 8: Going forward deployment in multi-storey buildings
8 apartments with existing control exhaustion in apartment houses in Harlev J have been operating with the need-based control exhaustion with humidity control developed in the project for almost a year. The energy savings were calculated at approx. 30 kWh/m2 floor space. The simple repayment period TBT was approx. 4 years. The residents are content with the solution. The solution complies with BR2010; however, it also points to potential future requirements in BR2015 and BR2020. The potential savings related to need-based control in the existing building stock with control exhaustion installations amount to approx. 685 GWh (heat) and approx. 50 GWh (electricity).
