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 .
- 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.

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.
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.
Health & Comfort
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.

Energy concept LoW-E
Low-E Ingenieurgesellschaft für energieeffiziente Gebäude
Prof. Dr.-Ing. Lars Kühl, Am Exer 10, 38302 Wolfenbüttel
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.

Wooden facade with integrated PV modules
Deimel Oelschläger Architekten Partnerschaft
In the southwest and southeast façade the wall construction was reduced to include the PV modules. In order to meet the technical and fire safety requirements, an external cement board was installed. The technical basis was developed by means of an expert opinion.
Great emphasis was placed on the creative integration of the PV modules in the building facades.
The PV modules form a level with the cleaned surface and are largely integrated in the façade level.

Winter garden as a climate buffer
Deimel Oelschläger Architekten und Low-E Ingenieurgesellschaft für energieeffiziente Gebäude
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.

Research project "High Tech Low-EEx Energy Efficiency Berlin Adlershof 2020"
BTB Berlin und TU Dresden
Three investors are currently involved in the innovative "Living on Campus" pilot project: two large Berlin housing associations and one subassembly. All have installed solar thermal systems on the roofs of their buildings. The quarter is located not far away from the cogeneration plant Adlershof. The BTB's modern cogeneration plant is powered by natural gas and feeds the heat, which is generated by 90% in cogeneration, into a network that goes far beyond Adlershof, which also supplies the newly connected residential district.
The TU Dresden scientifically accompanies the pilot project "Niedertemperaturnetz" over two heating periods and evaluates the results.
Common research contents of the NEWTONPROJEKTS with the BTB are:
• Utilization of renewable energies via utility grids during off-peak hours
• Organization and operation of "intelligent house stations" for the storage and withdrawal of heat in the internal and public supply network.
• Development of strategies for the organization of dynamic heat extraction costs / feed-in tariffs as a function of temperature / exergy level and load level in the grid (summer / winter, outside temperature level) .Heat in the internal and public supply network
With their coordinated facades and color concept, the three four-storey buildings form a uniformly designed ensemble in the new residential area in Adlershof. The shared green courtyard contributes to the improvement of the environmental microclimate and the partial facade and green roofs.
