  2. 11. Building Performance - Methods for Improved Prediction and Verification of Energy Use and Indoor Climate

    Author : Hans Bagge; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Use; Residential buildings; Prediction; Verification; Measurements;

    Abstract : Reducing CO2 emissions is one of the most important goals in Europe as well as the rest of the world. To reach that goal, the use of energy must be reduced. Thus, the building industry is facing a great challenge. Not only energy efficiency but also sustainability is desirable in the building stock. READ MORE

  4. 12. Evaporative Cooling Tower and Chilled Beams. Design Aspects for Cooling in Office Buildings in Northern Europe

    Author : Bengt Bergsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilot plant; cooling tower; simulation; low energy cooling; cooling tower model; free cooling; chilled beams; evaporative cooling; commercial buildings; hydronic cooling system;

    Abstract : The purpose of this thesis is to examine a comfort cooling system consisting of a hydronic cooling system with an evaporative cooling tower and chilled beams. The system has no conventional chiller. READ MORE

  5. 13. Demand Controlled Ventilation (DCV) Systems in Commercial Buildings. Functional Requirements on Systems and Components

    Author : Mari-Liis Maripuu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DCV; CO2-sensors; indoor climate control; energy efficiency; CAV; mixedgas;

    Abstract : Demand controlled ventilation (DCV) is considered as an energy efficient solution forair-based cooling and indoor air quality control. Considerable energy savings can beachieved when the airflow rate is continuously adapted to the actual load condition. READ MORE

  6. 14. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

    Author : Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peak heat load shaving; renewable energy; ventilation heat recovery; frosting in heat exchangers; Heat transfer; förnybar energi; ventilation värmeåtervinning; frosting i värmeväxlare; värmeöverföring; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

  7. 15. Adapting Variable Air Volume (VAV) Systems for Office Buildings without Active Control Dampers

    Author : Mari-Liis Maripuu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate control; CAV; variable supply air diffuser; ventilation; VAV; energy efficiency;

    Abstract : In commercial buildings the building services systems may account for a substantial part of the need of energy. There is, at least in Sweden, a large existing stock of 20 to 30 year old office buildings, which are supplied with centralised constant air volume flow (CAV) air conditioning systems with the primary function to keep the room temperature at an acceptable level summertime.
