The lab works to make every home healthy, comfortable, and energy-efficient by harnessing the power of the sun.
AboutAbout the lab
Warm and cool living on minimal energy.
Mae Lab (Maelab) researches the component technologies and design methods needed to decarbonize housing.
Its goal is a society where everyone, anywhere in Japan, can live healthy, comfortable lives without worrying about electricity bills.
The lab's research rests on three pillars: experiments in facilities such as a rooftop test building, field measurements in actual homes across the country, and simulation, with particular emphasis on field measurements.
The lab also supports the design of eco-houses that are actually built, placing great importance on a hands-on, on-site approach.
Key terms
- Decarbonization
- Efforts to reduce carbon dioxide emissions and move closer to net zero
- Latent heat storage material (PCM)
- A material that absorbs and releases a large amount of heat when it melts or solidifies at a set temperature
- CFD
- Computational fluid dynamics: a method that divides a room into a fine mesh and uses a computer to reproduce airflow and temperature distribution

With the overarching goal of delivering a healthy, comfortable life that is warm and cool, at the lowest possible energy cost for the long term, to everyone, the lab studies energy saving in housing and the use of renewable energy. Combining experiments, field measurements, and simulation, its research extends from detached houses to apartment buildings and school buildings.
*Illustrative imageEliminating Heating with Solar Gain and Thermal Storage
The lab aims to create homes that need no heating by storing solar heat taken in through windows in the building structure, using materials such as latent heat storage materials (PCM), and keeping rooms warm through the night. It verifies this using a full-scale test building on the rooftop and CFD.
*Illustrative imageHeating and Cooling with Solar Energy
In joint research with OM Solar, the lab studies OMX, a system that provides heating, cooling, ventilation, and hot water together using solar heat collected by the roof and an air-source heat pump. It also collaborates on the design of actual homes.
*Illustrative imageInsulation and Heating Retrofits for Existing Homes
To promote insulation and heating retrofits of existing homes, the lab conducts interviews with renovation contractors, uses simulation to visualize the effects of retrofits, and carries out web surveys of homeowners.
*Illustrative imageEnergy Efficiency in Multi-Family Housing
For multi-family housing, where insulation, equipment, and the use of renewable energy have lagged behind, the lab develops methods to improve indoor environments and save energy through simulation and field measurements, targeting reinforced concrete (RC) condominiums and wooden apartment buildings.
