One of the world's largest housing R&D centers

Sekisui House is carrying out various housing-related R&D projects at its research centers. Among them, its Comprehensive Housing R&D Institute is one of the world's largest research centers of its kind, where research is conducted to develop proprietary housing technologies and offer attractive proposals for new lifestyles. With this institute at the core, we hope to lead the world with our forward-looking approach.

R&D on better housing environments

Opened on a site that spans 7,000m² in 1990, the Comprehensive Housing R&D Institute consists of an R&D center that is responsible for the development of architectural technologies, the evaluation of housing performance, and the proposal of new lifestyles; and the Nattoku Kobo Studio (Home Amenities Experience Studio) that explores ideal housing with input from residents.
Through R&D on both structural performance and comfortable living, the institute is helping to create better housing environments.

  • R&D on better housing environments

    Comprehensive Housing R&D Institute
    The Comprehensive Housing R&D Institute is one of the world's largest research centers of its kind, where intensive R&D efforts are underway to achieve greater safety and living comfort, and the pursuit of technical innovations is continued.

  • Home Amenities Experience Studio

    Home Amenities Experience Studio【**CLOSED FOR RENOVATIONS**】
    Here, visitors can check, use and compare various housing factors first-hand with their five senses, and develop a true understanding of homebuilding beyond mere data.

From high-precision measurements to large-scale experiments

At Sekisui House, we conduct tests on the seismic performance of structures and the durability of construction materials to check the basic performance of our housing products, and use the test results to further enhance safety and comfort.
Performance tests conducted in-house enable us to promptly identify problems and take measures without delay, thus contributing greatly to improving our housing performance.

  • Shaking table test

    Shaking table test
    Shaking table tests are conducted to check how the shaking of a large earthquake and inertial force applied to exterior walls can affect structures.

  • Fire resistance test

    Fire resistance test
    Fire resistance tests are conducted by burning actual components to check how exterior walls can protect housing structures from fires that occur outdoors, and how interior components can resist fires that start indoors.

  • Assessing the durability of building components

    Assessing the durability of building components
    Super-accelerated weatherability tests can reproduce damage from ultraviolet rays and heat in a short period of time. The tests are conducted to measure the longevity of high-polymer materials such as paints.

  • Structure testing laboratory

    Structure testing laboratory
    In order to enhance housing performance, real-size structure tests are repeatedly conducted at this laboratory to measure and inspect structural strength.

Creating solutions for new lifestyles

Housing environments ideal for living with a pet; or for the healthy growth of children; or for senior lifestyles - the needs for housing designs vary from family to family.
We conduct research and development on new lifestyles from customers' perspectives to ensure safe and comfortable living for all with our proprietary solutions, such as the Airkis high-quality indoor air system that is beneficial to the health of children, and our original "Gururin Dannetsu" high-efficiency thermal insulation system that contributes to healthy living and energy conservation, as well as universal design.

  • Universal design research

    Universal design research
    Research on user-friendly housing equipment and spaces is underway by means of human engineering experiments involving people of different age groups.

  • Housing suitable for living with pets

    Housing suitable for living with pets
    We are conducting research on housing suitable for living with pets to create a healthy and comfortable living environment both for owners and pets. For example, we test the comfort of different floor finishes for dogs to walk on.

  • Research on sound insulation and indoor acoustic

    Research on sound insulation and indoor acoustic
    We conduct experiments to check floor impact sounds and acoustic isolation performance in a reverb chamber where sound reverberates well. We also measure acoustic power levels in an anechoic chamber that is lined with sound absorbing materials.

  • BMI Technology for the elderly

    BMI Technology for the elderly
    R&D efforts are underway to develop BMI technology that allows elderly and physically handicapped people to control electric appliances and wheelchairs just by thinking about such objects.
