Energy-intensive building

NEWTONPROJEKT won the Energy & Temperate Climates Prize of the 2019 Green Solutions Awards at the Germany level + the international Energy & Temperate Climates Prize.

The project was conceived as a flagship project for innovative sustainable district development with an assembly and a joint plus energy concept in wood construction.
The three buildings have a significant reduction in CO2 emissions due to their high-quality passive house construction and their energy concept. It is assumed that the KfW Efficiency House 40 Plus standard will be surpassed in practice and a negative annual energy demand will be achieved. This means that the houses generate more energy than the inhabitants consume.

House 1 completes the settlement to the north. It consists of 13 plugged apartments between 50m2 and 150m2. To the street in the northeast are stairwells and adjoining rooms. In the southwest, to the courtyard side, there are the lounges and upstream conservatory. Flexibility in floor plan design was especially considered in the design process.
The mixed construction of solid reinforced concrete core and curtain-mounted wooden façade makes it possible to reduce the thickness of façades with high insulation requirements. The wooden windows have a triple glazing. The materials used on the façade are eco-friendly made of wood, the insulation made of cellulose and recyclable wood soft fiber.

Owner approach of sustainability

  • As a construction community NEWTONPROJEKT GbR, we realize the three multi-family houses in passive house standard with plus energy since May 2016 as a multi-generational community. Floor plans were flexible and customizable in the planning phase. As builders, we make all decisions democratically. Our project fits well into the emerging new residential district of the city of science Adlershof with many companies related to energy. Through our members we maintain professional, family and other connections in the city of science and the surrounding area.
  • With our concept of feeding solar heat as storage into the Adlershof district heating network and, if necessary, taking it back there, we are combining in an innovative way with the infrastructure and jointly shaping the climate-friendly energy future Garden and community are very important to us. The three residential buildings are grouped around a courtyard garden, which can be shared by all residents. All rainwater is discharged into the surface under a combination of superficial infiltration and trenches.
  • Adlershof Projekt GmbH plans to extend this plus energy concept to other future construction phases on the site in Adlershof. Housing is currently booming and many locations are being reopened. In the development of new urban neighborhoods and locations, there is an opportunity to build decentralized, energy-generating neighborhoods through integrated development already in the development and planning phase, to optimize self-consumption through integrated storage systems for electricity and heat, and to existing or new heating grids and facilities to use. In addition, the Newton project provides valuable preliminary work, which will be published with scientific evaluations ( DBU project, BMWi research ), implemented in real terms and can serve as an example .

Architectural description

  • Floor plan
  • The house 1 in the Newton project consists of 13 apartments between 50m2 and 150m2 living space. The floor plans were planned as plugged apartments. To the side of the road in the northeast, the side rooms and staircases are designed. In the southwest to the courtyard side each apartment receives an unheated conservatory. Flexibility in floor plan design was especially considered in the design process. With the aid of a switch room, the floor plans could be reduced or enlarged and small apartments could be joined together to form a large family apartment. Thus, the development of individual solutions according to the needs of the builders has been made possible.
  • Innovative facade system
  • An important point that brings a special public perception of the project, is the facade with a PV system. Great importance was attached to the creative integration of the PV modules in the building facades. Thanks to their flat substructure, the PV modules on the south façades could be integrated flush with the cleaned surface. In addition to the development of the technical basics in the planning, the challenge lay in the implementation of the PV system on a wooden facade in coordination with fire protection, building services and contractors as well as the technical optimization of the PV system and the selection of storage for the selected energy management system of the building complex.

Energy consumption

  • 6,68 kWhpe/m2.year
  • 62,08 kWhpe/m2.year
  • DIN V 18599

  • 42,00 kWhfe/m2.year
  • DHW heating 19 kWh / m²a
    Heating 25 kWh / m²a
    Ventilation 0,29 kWh / m²a

    With a primary energy requirement of 7 kWh / (m². A) for house 1, the plus energy standard is thus almost completely achieved in terms of primary energy. In workshops with the builders, various energetic concepts were presented and discussed in terms of energy and economic aspects. As a result, the planning with photovoltaic was reduced to the south-oriented building facades, and implemented only on House 1.
    Nevertheless, it is assumed that in practice almost a negative annual final energy demand will be achieved. A power-to-heat control also enables power to be fed into the heat supply system even if there is excess electricity from PV. A battery system allows an own power usage of more than 50%.

  • Decentralized water heating

    To further reduce energy consumption, legionella-free hot water stations have been installed in each apartment. As a result, the temperature of the central hot water preparation is lower and the energy losses are minimized.

    Ventilation system with heat recovery

    The decentralized ventilation systems with heat recovery provide the apartments with heat. Their controlled ventilation provides more than 80% heat recovery from the exhaust air. Additional radiators are only necessary in bathrooms. The supply and supply air is realized via the facades

    heat supply

    The heat is supplied by the in-house solar thermal system. The excess hot water is fed into the district heating network of the Blockheizkraftwerks-Träger- und Betreibergesellschaft mbH Berlin (AGFW certified 2013 in accordance with FW-309 with fp = 0.24) as part of a pilot project with return connection through the integration of a bidirectional heat transfer station.
    A power-to-heat control also enables power to be fed into the heat supply system even if there is excess electricity from PV. The Energy Concept as Plus Energy The multi-family house incorporating the district heating network is unique in this form.

    Use of a photovoltaic system

    The two neighboring buildings form an energy network with house 1. On the roofs of houses 1 + 3, as well as on the facade of house 1, there are PV modules, on house 2 solar thermal. The energy gained from the PV system is distributed to all apartments via an internal network.

    The performance is counted in the proof and simplified divided equally among all three houses. The present report assumes a grid feed-in of 79,000 kWh / a with a calculated total electricity requirement of 74,000 kWh / a. In the context of the following EnEV verification, it is assumed that approx. 68,000 kWh / a will be used.

GHG emissions

  • 2,87 KgCO2/m2/year
  • EnEV calculation (2016)

    Thanks to its high-quality and environmentally friendly construction, especially the façade, as well as its modern and efficient energy concept, the building has a reduction in CO2 emissions. With a value of 2.87 kg / (m2a), the CO2 emissions are 40%

Life Cycle Analysis

    Use of renewable raw materials The use of renewable and environmentally friendly raw materials has been implemented in the building envelope. The curtain wall is clad with an internal OSB panel and an externally recyclable soft-wood fiberboard and filled with cellulose. The windows are made of wood and with triple glazing. Dismantling and separation The curtain walls are wooden stud walls with recyclable wood fiber boards. The connection to the supporting structure takes place by means of mechanical measures that enable the dismantling of the elements.

Water management

    The paved surfaces in the outer space are planned as drainable coverings and are designed as far as possible with wide joints. All rainwater is discharged into the subsurface in a combination of superficial infiltration and trenches. The open construction allows the gravel areas to be used as infiltration areas for the paved paths. The coverings are made in unbound construction, drainable material with wide joints is provided. As bedding is a sand / grit mixture, for
    the base courses planned a mineral mixture.

Indoor Air quality

    The ventilation system allows the house to be completely heated with air. The passive house has a high level of comfort through the ventilation system , the constant exchange with fresh air. The apartments are all equipped with a simple regulation for the ventilation system (room thermostats and air quality sensors) and a Nachheizregister equipped for individual control.


    Comfort through conservatory A special focus in terms of comfort was the unheated winter garden in the south facade. This serves as an energy buffer and as a living space extension. The floor-to-ceiling windows of the outer conservatory facade can be generously opened as a folding system in the wooden stud wall. The integration of the winter gardens in house 1 has positive effects on the annual heating requirement and the thermal comfort. Thermal comfort The exterior walls are thermally comfortable with triple glazing. The apartment partitions and ceilings were made of reinforced concrete and allow to store heat. exterior shutters As part of the research, the shading system of the conservatory facade was developed in various variants and discussed with the users. The result was an outdoor venetian blind, which allows both shading, glare protection and privacy and can be operated electronically. Exterior quality The design of semi-private semi-communal green spaces in multi-storey housing promotes our social cohesion and provides space for a variety of activities. The three residential buildings connect a common garden, which is designed as a social meeting place for the residents. Accessibility The house was designed barrier-free and adapted individually with the residents. There were floor level showers in the bathrooms.

    The wood construction allows a high level of comfort in the acoustics of the rooms.

    Management / Others

    Low-E engineering company was involved in the project from the beginning as part of the integrative planning process.
    As part of the planning phase, various approaches to care were developed and compared with one another. In addition to centralized solutions, decentralized solutions should also be considered. By integrating all those involved in planning, as well as the client and the user, all the levels of requirements for the execution and operation of the buildings are to be included in the planning.
    As part of the concept development for the energy supply of the "Solar Plus Energy" development in Berlin Adlershof, a total of 6 different variants with regard to the provision of heat and electricity are being examined in the preliminary planning phase. The passive house standard of the buildings with the corresponding U-values and a maximum annual heating requirement of 15 kWh / (m²a) is set in all variants.

    Further simulation tools were used for the development of control strategies as well as for the investigation of room concepts, climate buffers and different temperature zones within a dwelling.

    Opere strutturali / Sistema passivo

    The winter gardens are being developed as so-called "additional rooms". Due to the solar radiation and the outflow of heat from the building, it is assumed that the rooms are frost-free even during the winter period and can therefore be used most of the year. Energetically, they can be considered as buffer spaces. The thermal behavior and the resulting operating room temperatures are investigated by a thermal simulation.

    In particular, the influence of conservatories on the annual heating demand is the subject of the investigation. In terms of construction, the conservatories should be designed with 2-fold WSV glazing with a U-value of 1.1 W / (m²K).

    This version as a double EnEV façade is the result of a study on the cost optimization of the facades in relation to the requirement for frost-free and energy buffer. The conservatories should be run unheated.
