Architectural description
The ACCENT VERT & ACCENT ECO project is located on the outskirts of Warsaw on former agricultural land, in a neighbourhood that is today rapidly developing and will soon be just next to the new metro line. The buildings are located just a few hundred metres from one of the main North-South motorways in Poland, making it easy to reach from the centre of Warsaw. Situated near Gorczewska Park, the project already benefits from all the infrastructure in the Bemowo district such as schools, businesses, shopping centres and service stations.
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.
The neighbouring area of Bemowo district (Chrzanow estate) is one of the most rapidly changing areas in Warsaw in terms of new residential developments.
Both building have 5 floors with 1-, 2- , 3- and 4-bedroom apartments with surface between 26 and 75 sqm. Each apartment has own balcony, terrace or garden.
Energy consumption
- 90 kWhpe/m2.year
- 105 kWhpe/m2.year

Product
-
Viessmann solar heating system - DIS 50

HVAC, électricité / heating, hot water
There are ten solar heating system panels installed on the roof of Accent Eco, with nearly 5 sqm of surface each.
Because of its innovative character and contribution to decreasing the pollution, the product received an undivided acceptance of all members of the project team.

Dynamic thermal modelling by Arup

HVAC, électricité / ventilation, cooling
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.

Urban environment
The ACCENT VERT & ACCENT ECO project is located on the outskirts of Warsaw on former agricultural land, in a neighbourhood that is today rapidly developing and will soon be just next to the new metro line.

The main target of project's team was to create a pleasant environment. Apartments exposure has been set on the advantageous east-west axis ensuring lots of natural daylight inside. Attractive greenery and small architecture, presence of a water reservoir and vegetable garden are other ‘green’ aspects of this scheme.
The developer has also implemented solutions targeted at promoting ‘eco-mobility’ - provision of multiple bicycle racks for inhabitants and the bike path on the adjacent Batalionow Chlopskich st. delivered few years ago by Bouygues Immobilier Polska.
Furthermore, simple and aesthetic shape of buildings, designed in line with local zoning constraints, create pleasurable entourage advantageous for inhabitants’ rest. Buildings’ visual attractiveness has been achieved by its proportions, eye-catching arrangement of windows on the façade and unique shape of balconies.

Parking spaces
- over 180 bike racks on the surface.
- 250 parking places in underground carparks below buildings for its inhabitants.
- 64 external parking places in total, including 20 publicly available and 8 for handicapped.
Delivering attractive product - what is crucial for the customers - in line with the budget of future buyers, project certification did not result in any price increase. The project’s team target in the beginning was to deliver to clients high-quality flats in good location at a price which would be competitive for first-time buyers and Bemowo residents willing to move to a new and comfortable home. In the end, the developer managed to deliver a place with a definitive competitive advantage compared to many projects of other developers in this part of Warsaw. For the same price, the customers have received a product which is consistent with the group's values: respect for the environment and improvement in the residents' quality of life.
Building and its neighbourhood - the main target of location’s analysis was to create a pleasant environment.

Buildings’ visual attractiveness has been achieved by its proportions, eye-catching arrangement of windows on the façade and unique shape of balconies.
Technical, sanitary and environmental quality of materials, works and finished elements - thanks to implementation of a procedure regarding design, material choice and approach for execution of works, only the certified and attested materials have been approved for use on construction site. As a result, the risk of using materials affecting users’ health or of carcinogenic potential has been significantly mitigated. In the end, thanks to the analysis and comparison of technical qualities of available materials, only those of highest quality and durability have been selected, with no negative influence of the apartments’ price.
To conclude, the use of high quality anti-dusting paints and finishing materials as well as long ventilating of apartments before their handover, have all contributed to the better quality of living space and sanitary quality of air.
Responsible construction - in this field main have been focused on regular monitoring of water and electricity consumption for construction purposes, limiting the number of construction waste (i.e. using concrete waste to create concrete slabs for a temporary road for construction purposes), proper waste sorting and handing it for recycling to specialised firms, as well as responsible storing of materials and rubbish targeted at diminishing the risk of polluting the environment.
Energy management - in cooperation with ARUP, the appointed international engineering consultancy firm, a dynamic thermal simulation model has been created in order to assess the possibilities of optimising the buildings’ energy performance. Moreover, at the design stage, the architects have resigned from unnecessary partitioning the buildings in favour of a simple form, which cuts back the heat losses.
In part of the building, there is a solar panel installation to heat the utility water which contributes to decreasing the demand for energy in summer months. In common parts, there is a movement activated lighting system, with some twilight sensors and external LED lighting. In addition, the used elevators in the buildings are also energy efficient.
Acoustic comfort - the design team has paid particular attention to implement solutions targeted at protecting apartments from unnecessary noise, which concerned in particular the activities related to design and execution of sound insulation between apartments and installation or machines, with a special emphasis on the elevators.
