Savings from lighting according to requirements

KNX can control large groups of lights, either directly or by integrating the DALI standard, which enables the regulation of LED and fluorescent lights. The control can limit the maximum power values, as well as grouping the lights in lighting scenes. It also enables the use of astronomical clocks and conventional clocks to programme the on and/ or off times. On the other hand, when the external lighting provided is insignificant, the shades or shutters may be lowered to avoid light radiating to the outside.

It is possible to locate elements or rooms that consume more water than the average and then correct this trend and save on resources and energy

A good example in KNX can be found in sensors that are able to measure the water flow through a pipe. Thanks to this, it is possible to display instant information or generate records

Air renewal without losing hardly any HVAC indoors 

Thanks to KNX heat exchange systems can be controlled; the air inside a building can be renewed without incurring extra HVAC expenditure. Air renewal can be integrated with other systems that optimise it, such as detection of open windows, cool air recovery on summer nights (free cooling), or humidity and CO2 level management among others.

Services that KNX for LEED offer to you

How show KNX solutions for LEED certification

Our Values

We firmly believe in the efficient use of energy through applying standard control technologies such as KNX and especially its implementation in sustainable buildings certified as LEED.

We are consultants

We help manufacturers and KNX integrators to make their products and control solutions LEED strategies visible. And just as architects and developers to find ways to cope with LEED projects using KNX technology.

We bring knowledge and experience

We work closely with the KNX providing publications and participating in events worldwide. We have direct contact with the whole group of companies that represent standard KNX control. Our professionals have done KNX projects with energy efficiency solutions and have worked in manufacturing companies.

Advise and train

We know the KNX standard control solutions and how to implement them in LEED projects. We connect businesses between both standards and give advice and training to carry out successful projects. We show the characteristics of each KNX product that makes them valuable in monitoring solutions to undertake LEED strategies.

KNX Products: Weather Station

knx for leed weather station  inphography

The best example of multi-sensor, the device is certainly  KNWeather Station ready for measuring different variables useful in establishing energy efficiency actions and control strategies that help achieve LEED.

Knowing precisely the outside temperature, if it is day or night, if it's raining, wind speed, solar azimuth and the level of external brightness is very useful for efficient programming of lighting and air conditioning, and even control irrigation, stopping it if it's raining or activating at night to avoid evaporation losses too.

Have far more than one variable in the same product, can minimize the number of elements necessary for the control, which reduces the cost of implementation of each project of sustainable construction. KNX has a wide variety of weather stations, which allows the architect to choose the most suitable not only in functionality but also in design.

A.1. Maintain site lighting to prevent light pollution

Savings from lighting according to requirements


It can limit the emission of light to the outside, by lowering blinds or shutters step-shielding of the inner light outside the building.

This drop can be performed automatically using integrated twilight sensors KNX weather stations that measure the brightness outside and allow natural light during the day and lower the blinds and shades at night, as well as in public housing. These twilight sensors can activate and deactivate the lighting outside the building by switching on the exterior lighting when the light outside is low, at dusk for example, and switching it off when the sun starts to rise in the morning and natural light outside is sufficient. 

Integration in a control system allows a dynamic control of the heat and especially the light, according to the needs of each area of the building, by taking atmospheric changes and the external temperature.

It is possible to locate elements or rooms that consume more water than the average and then correct this trend and save on resources and energy

KNX weather station is common to other processes or strategies. In this particular case it can monitor meteorological variables (rainfall, wind speed and temperature) and overlay these variables with consumption data, and therefore contextualise whether water consumption (irrigation) increases are due to poor rains. 

 

 

B.2. Select efficient irrigation technologies

Efficient use of irrigation valves and water

KNX weather station is common to other processes or strategies. In this particular case, it detects whether it is raining, and cancels the irrigation process accordingly. This saves either stored water (from rainwater) or water consumed directly from the public supply system

E.6. Control Humidity

 

knxforleed products GIRA weather stationDehumidifiers are energy intensive, so if their operation can be avoided, a lot of energy can be saved.

Optimum humidity control is integrated with other related systems that improve the energy efficiency of the whole, such as the ventilation system of the building or the KNX weather station that indicates if it is raining or if there is a high level of external humidity that prevents dehumidifying by ventilation.

Dehumidification can also be achieved more efficiently, with less energy, by ventilating the room, provided the outside air conditions are suitable. This control data is provided by the weather station, indicating whether the day is humid (rain sensor) or if the external air humidity is high (humidity sensor).

 

 

E.7. Daylighting

 

knxforleed products schneider KNX weather station basicUsing the adequate and necessary amount of light helps to reduce lighting-related energy expenditure, which is usually quite high.

If the interior brightness average is available via sensors, it is feasible to adjust the artificial light depending on the amount of natural light. The control system is able to perform this type of constant light adjustment in response to the defined comfort and usage policies.

It must be taken into account factors that complicate the regulation, such as sudden changes in external brightness (a partly cloudy, partly sunny day), so no abrupt changes in the interior lighting are caused. It must be also taken into account the unpleasant effect of brightness increasing or decreasing quickly. The programming should provide for such everyday situations so that it is not a nuisance in the activity carried out in the area of the building with these types of regulations. The sensor may even be blocked for a while if sudden changes are detected, thanks to the brightness and sun position sensors (azimuth, height, coordinates). Its data is sent by the external KNX weather station and it can be used in these types of controls.
