Building services (HVAC & Lighting)

The building services dedicated to ensure a comfortable, healthy indoor environment inside buildings are known as “Heating ventilating and air conditioning (HVAC)”. With this purpose, HVAC systems are devoted to keep indoor humidity, temperature and level of pollutants within an acceptable or legal range.

In order to fulfil the comfort requirements of the users, the HVAC systems have to extract the heating or cooling load inside the building and provide fresh air from outdoors at room temperatures. These systems have one of the biggest shares of energy use in buildings. Therefore, it is very important to design the building based on passive strategies that minimize the need for heating, cooling and ventilation and active strategies that deploy high efficient systems with minimal consumption.

List of projects where this technology is being implemented.

BEEM-UP

BEEM-UP aimed to demonstrate the economic, social and technical feasibility of retrofitting initiatives, drastically reducing energy consumption in existing buildings, and paving the way towards massive market uptake. BEEM-UP involved building owners at three sites in France, Sweden and the...

E2REBUILD Site Voiron

The French demonstration site is a multi-storey building in Voiron in the Isère Department. The building was made of concrete with no insulation. The windows were first generation PVC double-glazing 4-6-4. The building had natural ventilation. All dwellings had an individual gas boilers for the...

E2REBUILD Site Roosendaal

The demonstration in Roosendaal, the Netherlands, consists of 70 identical single family terrace houses build in 1960 in the area of Kroeven. The full upgrade of the Kroeven area consists of 370 houses, of which 246 will be renovated and 112 units will be newly constructed, replacing about 100...

E2REBUILD Site Munich

The demonstration in Munich (Germany) consisted of two blocks of residential multi-storey buildings in the suburb of Sendling, built in 1954. The buildings were typical examples of the concrete brick constructions, built throughout Germany in the post-war era. The buildings are owned by the public...

E2REBUILD Site Halmstad

The demonstration in Halmstad, Sweden, is a multi-storey building from 1963 with typical features from that period, e.g. reinforced concrete load bearing frame and facade elements. The building contains 91 flats and is owned by the private housing company Apartment Bostad. The retrofit action for...

E2REBUILD Site Augsburg

The Augsburg demonstration is a multi-storey residential building in southern Germany with typical postwar characteristic features from the 60s and early 70s. It had originally a heat energy demand of approximately 220 kWh/m²/year due to its poor building envelope and leakages around the old...
