HVAC at Energy House 1

1.1.1 The University of Salford (UoS) is a leading public institution located in Greater Manchester, UK, with a strong reputation for combining academic excellence and industry engagement. Established in 1967, it serves over 20,000 students across undergraduate, postgraduate, and research programs. Salford is recognised for its close ties to industry, particularly in media, health, engineering, and digital sectors, supported by its strategic location adjacent to MediaCityUK. 1.1.2 The University operates two unique research facilities: Energy House 1 and Energy House 2.0. Both facilities contain environmental climate chambers that house test buildings. Energy House 1, located in the Cockcroft building, features a Victorian End Terrace House and was the first of its kind when constructed. The chamber enables the simulation of a wide range of European weather conditions, allowing for the testing of construction products and heating systems under controlled conditions environments. The environmental chamber has a dedicated heating and ventilation and air conditioning (HVAC) system. 1.1.3 After more than 10 year in operation, Energy House 1 is experiencing maintenance and performance issues with its existing HVAC system. Over time, both testing methods and the technologies under evaluation have evolved. For example, the introduction of Air Source Heat Pumps (ASHPs) has created new requirements for humidity control. The majority of work performed at Energy House 1 involves replicating outside temperature experienced during the UK heating season (-5 °C to +15 °C). Clients also express interest in performing research in extreme winter and summer conditions (-10 °C to +40 °C).
