Architectural description

The housing project located in Zac Copaya Matoury. It is a set of 15 buildings consisting of 80 townhouses LLS LLTS and 6 semi-detached homes in accession, all on 2 levels. The team of mastering is composed of 4 architects giving 4 writing distinct architectural style. In addition, the buildings of each architect are arranged to create a heterogeneous whole. All the houses are crossing with the large opening bringing a large porosity. Wide roof overhangs and sunshades provide optimum protection for the facades. Particular attention has been given to the materials thanks to the important use of local wood.

Energy consumption

  • 14,00 kWhep/m2.an
  • 128,00 kWhep/m2.an
  • 7,00 kWhef/m2.an
  • The conversion of final energy into primary energy is based on the values ​​of the 2015 regional energy balance. The Guianese electricity mix shows a coefficient of around 1.88 (for information, about 61% ENR and 39% thermal, in 2015). ).

Envelope performance

    The parameters Ubat and compactness of the building are irrelevant because in tropical climate, the most powerful solution (bioclimatic) is based on the natural ventilation through (it is better not to be compact) and the solar protection (the solar factor and not not the thermal conductance).

Systems

    • No heating system
    • Solar Thermal
    • No cooling system
    • Natural ventilation
    • Solar Thermal

    In Guyana, the temperatures are always high, there is no need for heating. For housing, the main source of energy saving is to avoid the use of air conditioning. For this, we work on natural ventilation.

    Each unit is equipped with an individual solar water heater type thermosiphon monobloc that cover 100% of domestic hot water needs (no extra).
    According to the Regional Energy Plan (2012), these avoided DHW needs are 1278 kWh per dwelling per year on average. The total energy avoided is therefore about 110 MWh per year.

GHG emissions

  • 5,00 KgCO2/m2/an
  • Given the electricity mix in Guyana (2015 data), the carbon weight of the electric kWh is 0.678 KGeqCO2 / kWh. Project emissions related to electricity consumption are therefore of the order of 41 tCO2e / year (5 KGeqCO2 / an.m2).

Product

    tel:18888301326

    HVAC / Ventilazione, Raffrescamento

    Air brewer with large wooden blades allowing ventilation of the parts in low winds.

    The Ecodom + Label imposes the supply of brewers in rooms and expectations in stays. In the rooms brewers can pose a problem in the case of bunk beds. It could be propose an alternative by the use of wall fans with grid of protection.

Urban environment

The project is part of the ZAC COPAYA. This is the first reconstruction operation in the area.

It will be accompanied by a set of collective buildings and shops oriented around the central mall, with local amenities (nursery, school, neighborhood house) sports equipment and a business cluster. This formerly isolated area will be connected to a main road connected by a roundabout. The buildings are served by a two-way street and a one-way street to give a residential character to the whole. Each house has a green space on the street including a parking space and a green area overlooking the garden. A pedestrian walkway provides access to the central mall.
