Breeam x Hotel Jansen

Hotel Jansen is designed to accommodate international young talent who come to Amsterdam for work or study, for a day, a month or 6 months. We have 200 fully equipped rooms, a restaurant and a laundry café.

We made our hotel as sustainable as possible

Our building is heated and cooled by a so called WKO system.  This heat and cold storage system is a sustainable method of storing energy in the form of heat or cold in the soil underneath the hotel. As a result, no gas is needed to heat the building.

We have 770 solar (PV) panels on the facade, roof and awning to generate electricity.

In all our rooms we have Energy-efficient LED lighting & presence detection.

We collect rainwater for at least 24 hours in case of heavy rainfall. After collecting, the rainwater is drained into the adjacent surface water gradually.

Our air treatment with heat recovery. We control CO2 in our rooms with varying occupation, such as the clubrooms and Café Jansen).

All wood is FSC certified (Forest Stewardship Council). This is the first international quality mark with strict requirements for sustainable and social forest management, supported by governments, companies and environmental organizations.

WHAT IS BREEAM?

BREEAM (Building Research Establishment Environmental Assessment Method) is a widely recognized and comprehensive sustainability assessment and certification program for buildings. It originated in the United Kingdom and is used internationally to evaluate the environmental, social, and economic performance of buildings throughout their lifecycle.

BREEAM assesses various aspects of a building’s design, construction, and operation, including energy efficiency, water usage, materials and resources, indoor environmental quality, ecological impact, and management processes. The assessment results in a BREEAM rating or score, which indicates the level of sustainability achieved by the building. Ratings can range from “Pass” to “Outstanding,” with “Outstanding” being the highest level of sustainability achievement. The goal of BREEAM is to promote environmentally friendly and sustainable building practices, reduce the environmental impact of buildings, and create healthier and more efficient spaces for occupants. It provides a framework for making informed decisions during the design and construction phases to ensure that buildings are built and operated with consideration for the environment and the well-being of people.

What steps did we take to reduce environmental impact

WASTE

The construction site waste was separated into 8 different waste streams, with a remarkable 94% (calculated by weight percentage) of the waste being reused through responsible collection and recycling by a certified recycling company.

ECOLOGICAL REPORT

Before the construction activities, a recognized ecologist prepared a report about the existing plants and animals on the construction site. Supervision during construction is maintained to consider the presence of plant and animal species. Recommendations from the ecologist, such as provisions for swifts, peregrine falcons, and songbirds, have been followed to promote sustainable cohabitation with animals.

AIRTIGHT CONSTRUCTION

Heat loss measurements during the commissioning phase demonstrated that the building meets design specifications for airtightness, supporting the energy performance of the building.

THERMOGRAPHIC MEASUREMENTS

Heat loss measurements during the commissioning phase indicated that thermal insulation has been correctly applied, without thermal irregularities.

AIR QUALITY

Construction and finishing materials used contribute to a healthy indoor air quality due to low emission of harmful substances.

RESPONSIBLE ORIGINS

At least 80% of the materials used in the main building components have a responsible origin.

WOOD CERTIFICATION

The wood used for the construction site is sustainably sourced and comes from a legal origin, certified by an approved certification system.

ENERGY CONSUMPTION

Energy usage on the construction site is monitored and reported to raise awareness during the execution of the construction project. Additionally, solar panels have been installed on the site office to generate sustainable energy.

CONSCIOUS BUILDERS

The contractor achieved a score of 8 with Conscious Builders, indicating their attention to employees, safety, environment, and the surroundings. Construction sites are assessed based on criteria related to these aspects.

RECYCLABLE WASTE

A dedicated communal area has been reserved for the storage of recyclable waste. This eliminates the need for additional space within the individual rooms to store recyclable waste. It offers a convenient and efficient solution to keep waste separated without compromising available room space.

ENCOURAGEMENT OF BICYCE USAGE

To encourage bicycle usage, (electric) shared bicycles have been provided on-site. This provides a convenient and sustainable way to facilitate cycling and encourages people to use bicycles as a means of transportation.

BUILDING GUIDE

A clear and user-friendly building guide has been created. This guide is specifically designed to support non-technically inclined users of the building, allowing them to understand and efficiently interact with the building. Providing this guide promotes trouble-free building use and enhances a pleasant experience for all users.

COMMUNAL KITCHENS

A communal kitchen and dining area have been established. This has several sustainable benefits:

1. Efficient Space Use: Sharing a kitchen and dining area optimizes space utilization. Instead of individual kitchens and dining spaces for each user, a communal space can be shared by multiple people, reducing the overall space required.
2. Reduction of Resource Consumption: A communal kitchen can lead to reduced consumption of resources like appliances and furniture. Instead of individuals purchasing their own cooking equipment and furniture, sharing these resources in the communal kitchen can result in less material usage and energy consumption
3. Social Interaction Incentive: A communal kitchen and dining area encourage social interaction among residents or users. This fosters a sense of community and can lead to shared meals, idea exchange, and collaboration. This social aspect contributes to the well-being and sustainability of the community.
4. Food Waste Reduction: In a communal kitchen, people can prepare shared meals and share leftovers, reducing the likelihood of food waste. By sharing ingredients and consciously managing food, a communal kitchen can contribute to more sustainable food usage.
5. In summary, having a communal kitchen and dining area promotes efficient space usage, reduces resource consumption, encourages social interaction, and decreases food waste, all of which contribute to a more sustainable living environment.
