  text: 'The construction of climate-friendly new buildings is not enough to enable
    greenhouse gas neutrality by the second half of this century. To achieve it, the
    existing building stock needs to be renovated or retrofitted step by step. This
    study investigates the impact of a low-investment greenhouse gas emission reduction
    measure based on intelligent room heat management (IRHM) which is being tested
    to date on the main administrative building of district Lippe, built in 1979-80,
    in Germany. This system intends to reduce the energy consumption of further districts’
    buildings that, due to the high costs, cannot be intensively renovated in the
    medium term. IRHM consist in the installation of an intelligent controller that,
    based on dynamic usage profiles, optimise the operation of the existing heating
    system. Through presence sensors in the office rooms, the employee’s worktime
    routine is continually registered to enable the creation of heating patterns that
    maximize heat comfort during worktime while energy is saved by reducing room temperature
    when the office is unoccupied. The analysis is based on collected data of heat
    energy consumption, room climate and user behaviour in five corridors: three with
    IRHM and two control corridors without it. In both control corridors and two of
    the IRHM corridors the façade was completely refurbished in 2021 while the remaining
    one still preserves the original façade to date. Heating demand calculations were
    conducted to enable a wider exploration of usage scenarios. The results obtained
    so far, show significantly lower heat consumption in the corridors with IRHM,
    reaching a maximum of 90% energy consumption reduction compared to the control
    corridors. An optimized operation of the radiators is clearly recognizable as
    the system anticipates the employee’s presence and reach the comfort room temperature
    (set-up temperature) before the beginning of the working time, keeping it while
    the room in use. It also reacts properly switching down to set-back temperature
    so far, no presence is detected. According to the heating demand calculations,
    the implementation of a set-back temperature out of worktime can reduce the energy
    consumption up to a 48%. Combined with the refurbishment of the façade, the heating
    demand sinks up to an 87%. Field data shows an even more optimistic perspective,
    as energy consumption was in average even lower than the calculated demand. The
    on-site implementation of the IRHM is accompanied by social science research aiming
    at getting feedback on thermal comfort as well as on employees’ experience with
    the handling of the intelligent room heat management device. Up to now three online
    surveys were conducted during heat periods between 2021 and 2023 with 18 to 21
    participants from two-person offices. First analyses show that occupants’ satisfaction
    with temperature changed from a neutral ranking to a slightly positive voting.
    Room temperature was found to be comfortable as soon as entering the office in
    the morning. Preferred room temperature shifted over the survey time points from
    21°C- 22°C to under 21°C. Further analyses will focus on general energy-relevant
    attitudes and habits such as windows-door opening.'
