This scheme consists of two multi-family residential buildings with 292 apartments in total. Moreover, under each building there is an underground carpark and there are multiple places dedicated to storing bikes on the surface.
BOUYGUES IMMOBILIER POLSKA sp. z o.o. - a company from the French BOUYGUES S.A. Group, is the developer of this project. Sustainable development forms essential part of the Group’s strategy, with a particular emphasis on the corporate social responsibility and environmental protection. BOUYGES IMMOBILIER implements these policies in a formal and organized manner, in accordance with respecting all shareholders’ interests, as well as maintaining employees’ satisfaction.Group’s efforts in this field have been visible in a variety of residential and office projects delivered within the last years, and also have been confirmed and appreciated by several prizes and certificates, including the HQE certificate.
The project has been designed by ARCHITEKCI DAWIDCZYK & PARTNERZY firm and constructed by PBM POLUDNIE S.A. - general contractors. Accent Vert has been handed to its inhabitants in December 2015, whereas the Accent Eco’s commissioning is expected in Q4’ 2016.

The DTM was used to analyse the building and its location (including sun path and shading analysis) and to provide a prediction of space temperatures and comfort conditions in the interior spaces.
The modelling has been carried out using the Warsaw weather data file to ensure that the model accurately reflects the location of the building.
The weather data used by IES include 8760 hourly records which enable the software to carry out dynamic building performance simulations.
The three-dimensional detailed thermal model has been created using plans, sections, elevations and general arrangement drawings provided by the project architects. The building’s orientation has been adjusted according to the site plan.
The results indicate that for this project, external conduction losses are only 6% of the total energy consumption for heating purposes. Improvement of external fabrics insulation resulted in unnoticeable energy savings when compared to increased investment costs.

Reasons for participating in the competition(s)
The weather and environment in Warasaw create difficult conditions for construction of residential buildings - hot in the summer, cold in winter with high amplitueds of temperatures and conditions, and what is more - multiple times within each year when the temperature crosses zero degree Celsius.
The presented case study confirms that the investor managed to create pleasant and nice place for its inhabitants which encompasses innovative solutions, previously unseen on the Polish residential market.
The combination of 'green' ideas at concept, design and construction stages contributed to delivering a project in which the investor has successfully demonstrated its expertise and commitment to sustainable development, which has been then finally confrimed by the HQE certificate.
