Better property planning and marketing: Why measure daylighting in real estate

Quite possibly the room you are currently in is having a significant effect on your mood. Light and daylight in particular, play an important role in determining if we feel comfortable in a space. Optimum use of daylight will provide for bright and cheerful rooms. And that will have a beneficial effect on our health. But are we sufficiently aware of what daylight means for our living spaces?

Although daylighting is mentioned as the third most important criterion when assessing the quality of a property, it is very often almost overlooked. Only if the effect of daylight is planned in a sensible and holistic manner can its positive effect on humans, their health, wellbeing, and efficiency fully develop.

The following therefore applies: If you make do with bad daylighting conditions, you lose out twice: Bad lighting conditions in living and workspaces result in a reduced quality of life for inhabitants and ultimately lower yield prospects for property developers or owners, too. Conversely, this means sensible daylighting will enable us to save on heating and electricity costs for artificial lighting or air-conditioning, too. However, to do so, you have to calculate or simulate lighting conditions first. 

Establishing daylighting quality

To establish daylighting quality, architects, planners or portfolio owners have to measure spatial and architectural daylighting ratios. Based on clearly defined, central parameters, like the daylight factor and the daylight availability the daylighting can easily be measured.

Archilyse offers a method that measures criteria that were previously ignored, such as the functionality of floor plans, the direct neighbourhood, the view or the brightness of an apartment.

Architects and planners often only obtain a situational impression of a property. With Archilyse lighting simulation data, however, property decision-makers can quickly see what the actual daylighting quality inside the different rooms of a home is. That is because the exposure to sunlight simulations precisely indicate -for every square centimetre- how much light enters the space at a certain time of year.

Improved real estate planning and marketing

This enables planners to quickly see whether rooms are exposed to strong solar radiation in the summer and are therefore prone to overheating, or whether a nearby tree robs the nursery of light. Archilyse will also help deduce suitable window areas in accordance with the floor map plan, the building floor and the orientation of the dwelling.

Property marketers will also see straight away how good a property’s lighting quality is and can then use these findings to better assess prices and conduct their marketing. It is also relevant to determine these issues to establish the energy demand of a building (e. g. for lighting). That is because sensible planning of windows makes it possible to use daylight to warm rooms, reducing costs for operators and tenants in the process.

Archilyse does not simply consider the orientation of a property, but also which floor it is on, and which other topographical or architectural conditions (e. g. balconies, trees, other buildings) limit daylighting.

Archilyse can be employed to undertake many time-consuming and costly tasks, for instance, surveys, in a more efficient manner, and to recognise planning errors at an early stage.

Archilyse automatically and efficiently checks just how good the quality of daylighting for a new construction project or the homes inside your property portfolio is.

You can establish for every building unit whether there is “healthy” daylight use in all rooms.

A comparison of two apartments in the sun simulation shows that the quality of light. That means that the brightness of the apartment, has an influence on the rental price. Archilyse helps to achieve a more precise assessment of a property’s quality which supports a better greater accuracy with regard to price estimates.

Measuring daylighting quality also provides information on a home’s future quality of life. Archilyse can, therefore, help to recognise planning errors inherent in architecture at an early stage, and to optimise floor plan or development plans.

Archilyse ultimately helps to interpret the architecture and real estate and supports decision-makers along the entire value chain with additional, objective fact.
