Objective
Application of an integrated comprehensive refurbishment method to an office building. The renovation of the building will reduce the energy consumption to levels below the ones of new buildings, improving the indoor climate (visual and thermal comfort). Renovation will be based on an integrated facade consisting of an upper daylight window, a vision window and a quick responding solar wall for preheating of ventilation air. Individual shades will be placed in front of the daylight and vision windows to maximize comfort. Movement sensors will control ventilation rates. BMS will control ventilation/lighting.
The integrated energy façade consists of an upper daylight window, a vision window and a solar wall for preheating of ventilation air. The solar wall is integrated with a quick responding low temperature heating element.
Solar shading and redistribution of daylight deep into the building is achieved via an exterior and a interior light shelf.
Ventilation air is preheated in the solar wall and, if necessary, post-heated in the integrated heating element. In each office a combined occupancy and light sensor will control the general office lighting, the ventilation rate and the temperature set-point of the space heating system.
When unoccupied a minimum ventilation rate of 0.2 - 0.4 h%¹ is maintained, being raised to 1.5h%¹ during occupation. The Building Management System BMS will override ventilation set-back, when passive solar can be delivered to the room via the solar wall, even if the room is not occupied. During occupation the daylight sensor will maintain a minimum lighting level in the room of 200lx. When the room is not occupied daytime or night-time, a minimum temperature of 17°C is maintained, being raised to 21-22 °C during occupation.
