ROOM-LIGHT 1:1 New Psychiatry Bispebjerg
The purpose of the project is to implement, examine and optimize the combination of daylight and dynamic LED artificial light Lattitude Compensated Architectural Lighting (L-CAL) in a new building class 2020 construction; New Psychiatry Bispebjerg. The purpose of the project is to optimize energy consumption for lighting and indoor climate by reflecting on the health aspects of daylight and dynamic artificial light in the planning and performance of a building class 2020 construction.
The project combines daylight and dynamic LED artificial light in relation to the construction of New Psychiatry Bispebjerg. The project implements better daylight and LED-lighting for the benefit of energy consumption and indoor climate, and collects data on health in later phases, through clinical randomized trials. In cooperation with New Psychiatry Bispebjerg, a rotatable 1: 1 mock-up of a patient room will be build, this will create a unique opportunity to investigate and gather knowledge about both daylight, dynamic LED artificial light and indoor climate through advanced (cumulative) light recordings, as well as IC meter measurements of air, CO2, temperatures in building class 2020 construction.
By testing and testing different scenarios with different daylight and different dynamic LED lighting, the project will qualify theoretical computational programs (BSim and Be15) with practical experience. This is done through a newly developed measurement method for daylight and LED-lighting. Here the project studies the importance of light quality for the building's energy consumption and health conditions in a building class 2020 construction. The project is followed by healthcare post occupancy studies, where daily rhythm, mood and sleep are investigated on a total of 192 single beds at Ny Psykiatri Bispebjerg. Here, the health studies will help to qualify and implement concrete light and indoor climate in relation to the concept and purpose of healing architecture.
The project will thus be based on improving the well-being and quality of life of the psychiatric patient involved, but the overall purpose of the project is that the health knowledge will be used more generally and generally in relation to Building Class 2020
Through registrations and analyses of daylight, temperatures and natural ventilation in the patient room, the project seeks to uncover how the natural differences of the building, caused by geographical orientation and outdoor diurnal variations affect the indoor environment, in order to create a balance between on the one hand, daylight and the need for artificial lighting and on the other hand the demand for active and passive cooling, using mechanical and natural ventilation. The analysis also looks at the potential health aspects of daylight and fresh air and proposes a new strategy for dynamic artificial lighting and dynamic, mechanical ventilation, called Geographical Orientation Compensated Architectural Planning, GOCAP.
The new strategy divides the day into a morning scenario and an evening scenario, in order to reduce the total energy consumption. In this context, the report uncovers the indoor climate and daylight conditions based on two main parameters.
- The geographic orientation (N, S, E and W)
- The season (summer and winter).
Physical measurements in the patient room are supplemented with computer simulations to assess the need for ventilation and to see how natural ventilation can supplement and substitute mechanical ventilation at different times of the year.
Based on these data, the article proposes a new way to plan the indoor environmental quality, which can reduce the total energy consumption for lighting with 20 - 40% and the total energy consumption for ventilation with minimum 40%.
