Heating - Ventilation and Air Conditioning

  • Building Energy Management Systems (BEMS)

    Type: 
    Technology
    Objective:

    Managing the energy and other needs in buildings efficiently and intelligently can have considerable benefits. A building energy management system (BEMS) is a sophisticated method to monitor and control the building's energy needs. Next to energy management, the system can control and monitor a large variety of other aspects of the building regardless of whether it is residential or commercial. Examples of these functions are heating, ventilation and air conditioning (HVAC), lighting or security measures.

  • Heating- Ventilation and Air Conditioning

    Type: 
    Technology
    Objective:

    Heating, ventilation and air conditioning (HVAC) systems supply fresh air and condition the indoor air temperature and humidity of a building. HVAC is reported as the key energy user (37%) in US buildings (WBCSD, 2008), accounting for 59% of the energy used in China commercial buildings in 2000 (Levine et al., 2007). Therefore, HVAC is a key component of climate change mitigation potential in the building sector.

  • Energy Savings in buildings

    Type: 
    Technology
    Objective:

    Technologies and measures which are aimed at reducing the use of energy in buildings could have several advantages, such as lower energy bills, increasing comfort of living or working, and reduced impact on the environment, including reduction of CO2 emissions. The options considered for energy savings particularly leading to CO2 emission reductions include the following:

  • Instituto de Investigación Geológico y Energético

    Type: 
    Organisation
    Knowledge partner
    Country of registration:
    Ecuador
    Relation to CTCN:
    Network Member
    Knowledge Partner
    TA proponent

    IIGE is a research institute that promotes development, innovation and transmission of technology focused on energy efficiency and renewable energy. The institute aims to contribute to the sustainable development of the Ecuadorian society, through the implementation of energy efficient and energy renewable policies and projects.

  • Global Environment Centre Foundation

    Type: 
    Organisation
    Knowledge partner
    Country of registration:
    Japan
    Relation to CTCN:
    Network Member
    Knowledge Partner

    The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

  • Radiative Cooling of Solar Cells

    Type: 
    Product

    Background: Stanford researchers at the Fan Group have developed a novel method of passively cooling solar cells via a radiative cooling mechanism. The pyramid structures made of silica glass (shown in image below) provide maximal radiative cooling capability. Technology Description: We have developed a way of passively cooling solar cells that are exposed to the sun and hence heat up via a radiative cooling mechanism. This is an enormously important issue since solar cells operate at high temperatures which degrade both their efficiency and long-term durability.

  • Geometry for a Gradual Heat Exchanger

    Type: 
    Product

    A novel heat exchanger with gradual change geometry has a significantly higher efficiency than conventional heat exchangers. For example the novel heat exchanger may have a coefficient of performance (COP defined as ratio of kilowatts of heat transferred per milliwatt of mechanical energy dissipated) of 14 which is much higher than a COP of 0.25 to 3 for conventional heat exchangers. Applications of such a novel heat exchanger are an energy savings in pre-heating of clean cold water from used warm water and heat recovery in building ventilation.
