New Construction Hotel Jansen Amsterdam Bajeskwartier
History
The former Bijlmerbajes in Amsterdam, a prison complex, is being redeveloped into the “Bajeskwartier,” an eco-friendly multifunctional vibrant neighborhood. The total development includes approximately 1350 residential units, an educational institution, art galleries, recreation areas, healthcare facilities, student housing, shops, and a short-stay hotel named Hotel Jansen ‘not for tourists.’ Hotel Jansen is located in the ‘Knowledge Cluster’ of the Bajes Quarter. In collaboration with the housing corporation De Alliantie, a multifunctional building with 280 student residences (De Alliantie) and a branch of Hotel Jansen ‘not for tourists’ (200 rooms) is being developed. Hotel Jansen ‘not for tourists’ also develops and operates a commercial plinth with mixed functions within the building.
Design
The entire building has a vertical disc urban layout with notches and projections, creating a playful and lively facade. The building consists of Hotel Jansen and student residences for De Alliantie. The red line on the artist’s impression indicates the boundary between the two building parts. BREEAM applies only to the Hotel Jansen section. The total program of Hotel Jansen includes 200 student hotel rooms, 5 clubrooms (shared living kitchens), Mama’s restaurant/brasserie, a laundry café, approximately 200m2 of commercial space, bicycle storage for 200 bikes, and a parking garage for 13 cars.
BREEAM
(Building Research Establishment’s Environmental Assessment Method) is the leading and globally most used method for assessing the sustainability performance of buildings. Goals include realizing sustainable buildings with minimal environmental impact, providing a credible certification for sustainable buildings, and promoting the demand for sustainable buildings. BREEAM assessments are based on recognized performance criteria covering aspects from energy and water usage to ecology, pollution, transport, materials, waste, and management processes.
Breeam Outstanding
The aim is to achieve the BREEAM Outstanding certificate (5 stars) based on the BRL 2014 v1.0.1 guideline for both the design and completion phases. Key innovative and environmentally friendly design measures include low-temperature heating and high-temperature cooling (WKO), gas-free design, air treatment with heat recovery, presence detection in lighting, energy-efficient LED lighting, rainwater collection, greenery on some facades, PV panels on the facade and roof, and the use of FSC wood.

- Sustainable Measures Implemented
- Various sustainable measures have been implemented, including the use of energy-efficient technologies, rainwater harvesting, greenery on facades, and commitment to social and economic sustainability through partnerships with organisations such as House of Hospitality and the Amsterdam Social Return Bureau.
Ambitions and Planning
The ambition is to achieve the BREEAM Outstanding certificate for both the design and execution phases. Frequent meetings with the design team, client, and BREEAM expert are held to monitor progress.
Technical Solutions
Energy generation includes heating and cooling through a ground-source heat pump system. Air treatment in hotel rooms involves HR counterflow heat exchangers. Lighting utilizes energy-efficient lamps, predominantly LED lighting.
Process and Organization
Responsibilities for BREEAM are shared among the client, architect, main contractor, main installer, and BREEAM expert. The BREEAM expert acts as an advisor throughout the process and is responsible for verifying compliance with BREEAM guidelines.
Costs/Benefits
The costs associated with meeting BREEAM requirements are high, involving multiple parties to produce documents demonstrating compliance. However, the investment is justified, as a well-thought-out and energy-efficient building is believed to be more cost-effective in the long run and provides a more pleasant environment for occupants.
De investering in deze kosten zijn te verantwoorden, omdat we van mening zijn dat een goed doordacht en energiezuinig gebouw op de langere termijn goedkoper is in beheer en onderhoud, en dat deze een prettigere plek oplevert voor de medewerkers en gasten. Dit laat zich niet in euro’s uitdrukken maar is wel één van de belangrijkste voordelen.
Tips for Future Projects
To ensure a smooth process, it is advisable to share the responsibility for BREEAM among all parties involved, from the client to subcontractors and end-users. Early initiation of the process and regular status updates with all stakeholders are crucial.
