Progetic has undertaken the design and installation of all mechanical, electrical, and plumbing services, including:

  - Mechanical ventilation with enthalpy heat recovery with a Zehnder Comfoair Q600

  - Heating and cooling with Zehnder NIC300 radiant wall panels and two Zehnder Dew dehmudifiers/heating/cooling coils, together with low temperature radiators for heating and cooling on the top floor, powered by a Rotex HSPU Compact air-source heat pump with a nominal power of 8kW

  - Domestic hot water production with the same Rotex air-source heat pump, with instantaneous hot water production and a 500 l tank.

  -3.4kWP solar PV system for self-consumption, with power diverted to an electrical immersion heater in the hot water tank when no other loads are being drawn, controlled by the Loxone control system.

  - Loxone control and home automation system, integrating heat recovery ventilation, heating, cooling, external blinds, flooding alarms, video door station, and monitoring of general electrical energy consumption and heat pump and dehumidifier energy consumption.

  - Plumbing, water supply, waste water, telecommunications, electrical and lighting systems.

  - Deep energy retrofit to Passivhaus EnerPHit standard.
