Volume content
Model Predictive Control (MPC) of hybrid ventilation systems in office buildings with dynamic glass facades | 2015 | English | 16 pp
Assessment of spatial and temporal distribution of thermal comfort and IAQ in low energy houses | 2015 | English
According to the International Energy Agency, buildings represent over one-third of total final energy consumption.
In recent years, as an alternative to continuous control with the use of standard analog automation signals (voltage or current), the Pulse Width Modulation (PWM) control was introduced.
Improvement of comfort and energy efficiency in existing buildings using adaptive thermal comfort algorithm | 2015 | English | 11 pp
Comfort and energy saving are two important concepts treated in current buildings in order to maintain a good air quality reducing the energy consumption.
Thermal comfort improvement at the lowest energy consumption is a key issue when dealing with sustainability in buildings. An appropriate passive design is mandatory under those circumstances.
Impact of natural ventilation in energy demand and thermal comfort of residential buildings in Catalonia | 2015 | English | 10 pp
The most representative typology of residential buildings of Catalonia has been simulated in TRNSYS to evaluate the impact of both infiltration and natural ventilation. The typology is a block of apartments constructed during 1950-1980.
Experimental analysis of microscale trigeneration systems to achieve thermal comfort in smart buildings | 2015 | English | 10 pp
The transformation of the building energy sector to a highly efficient, clean, decentralised and intelligent system requires innovative technologies like microscale trigeneration and thermally activated building structures (TABS) to pave the way a
Optimization of the airtightness and the flow rate of air in nearly zero energy buildings | 2015 | English | 10 pp
The control of heat losses, inwards/out, in nearly zero energy buildings is of high importance. The transmission losses through the building envelope are easily reduced using larger amounts of insulation.
Uncertainty in airflow rate estimation of daytime ventilation associated with atmospheric stability | 2015 | English | 9 pp
We conducted observations of wind velocity profiles above a high-density area in Tokyo, Japan, using a Doppler LIDAR system.
With a tighter building envelope more minimal influences come into consideration.
IEA EBC Annex 68 – Subtask 4, Strategies for design and control of buildings | 2015 | English | 2 pp
The objectives of Subtask 4 are to develop design and control strategies for energy efficient ventilation in residential buildings which ensure high indoor air quality.
The objectives of Subtask 3 Modeling are to improve the understanding and develop prediction models on the impacts of outdoor pollutants, thermal environment, building materials and envelope, and indoor furnishing and occupant activities on the in
First the Subtask will organize a literature survey and make researcher contacts to gather relevant data and existing knowledge on major pollutant sources and loads in buildings, including models. Laboratory testing and model setup to provide exam
Subtask 1 of IEA EBC Annex 68 will aim at defining the metrics to enable a proper consideration of both energy and IAQ benefit in building design and operation
IEA EBC Annex 68 – Indoor Air Quality Design and Control in Low Energy Residential Buildings | 2015 | English | 2 pp
The overall objective of the IEA EBC Annex 68 is to provide scientific basis usable for optimal and practically applicable design and control strategies for high Indoor Air Quality (IAQ) in residential buildings.
Development of a compact single room ventilation unit with heat recovery dedicated to tertiary building | 2015 | English | 9 pp
In the frame of the European project called Bricker, a new prototype of single room ventilation with heat recovery has been developed. This new unit is supposed to be installed in class rooms of an educational institution.
Spread in energy use in buildings dependent on choice of heating and ventilation system | 2015 | English | 9 pp
The energy use in buildings is dependent on the choices made during the design, construction and renovation.
Primary energy used in centralized and decentralized ventilation systems measured in field tests in residential buildings | 2015 | English | 7 pp
Ventilation systems can save heat energy by using heat recovery, but consume electrical energy to power the fans.
Ventilation technologies are the key aspects to reach the target of nearly zero energy buildings.
