Single family house in Erlenbach 01

Single family house in Erlenbach

In this single-family house, the combination of solid construction with ClimateCoating® ThermoProtect and infrared heating with ClimateCoating® ThermoPlus ensures lower energy consumption than in the neighbouring house with a “better” U-value.

It is a single-family house. The wall construction consists of 24 cm porous concrete, inside and outside a total of 3.0 cm plaster and inside and outside coated with Thermo-Shield (i.e. outside with ClimateCoating® ThermoProtect and inside with Thermo-Shield Interior).

Heating is provided by IR (infrared) radiant panels, which consume primary energy-devil electric power and provide better thermal comfort than any convection heating can.

The infrared heating installed here, in combination with the IR reflective coating ClimateCoating®, creates maximum comfort and economy. For the period from March 2008 to March 2010, heating costs of less than € 450 p.a. have been verified.

At the same time, the evaluation of the measurement results leads the U-value theory ad absurdum. It is analytically and metrologically proven that the so-called U-value as a primary measure for the heating energy demand is a fantasy product.

The basis for the evaluation is a protocol from 2011 on measurements of the U-value of exterior walls of several single-family houses with different wall constructions. The measurements carried out prove the positive influence of Thermo-Shield Interior and ClimateCoating® ThermoProtect on the thermal resistance of exterior walls.

The task of the measurements was to prove the positive influence of ClimateCoating® on exterior walls with different wall constructions. Furthermore, the cooling behaviour as well as the warm-up phase of the air and the wall temperature should be determined.

The measurement locations were 2 single-family houses with different wall constructions. Measurements were taken on the west side of the house at a height of approx. 3-5m. All measurements were subject to largely the same conditions with a temperature difference between inside and outside of approx. 15°C. On the one hand, the TESTO 635 measuring device and the PT100 sensors were used. The wall structure of the neighbouring house consists of 36.5 cm aerated concrete, the U-value here is on average 0.30 W/m²K, as the manufacturer also specifies in his flyer.

From 20.02.2010 17:30 o’clock to 21.02.2010 9:00 o’clock different measured variables were measured in the room and outside:

  • – Indoor air temperature
  • – Air temperature outside
  • – Wall surface temperature inside
  • – “the U-value”
  • – rh [%]; probably the rel. Humidity outside
  • – Mat [%],the material moisture at unknown location

Here, among other things, one must ask the question as follows: What is being measured? Is it really the room air temperature? The wall surface temperatures rise because the IR heater emits heat radiation. In addition to the primary radiation, the secondary radiation also has an effect. This is the reason why even concealed wall surfaces that are not in the direct cone of the heater, e.g. behind an armchair, become warmer.

The sensor for the room air temperature therefore does not display the actual measured variable, but a higher value. This is because it is radiated in the same way and thus heated.

When it comes to radiation processes, the U-value theory is out of place. It merely adds to the confusion and dilution rather than providing a model explanatory contribution. This is because radiation processes are foreign to the nature of the U-value theory.

The room air temperature is not the determining variable when it comes to IR processes. This involves radiation physics in the wavelength range around 10 µm in the following cases:

  • – surfaces coated with thermoceramic membrane technology (IR reflection)
  • – Heating with heating systems based on the principle of heat radiation (IR heating)
  • – the combination of IR heating and IR reflective coating

By combining the IR heating with the ClimateCoating® coating, the occupants of the single-family house in Erlenbach achieved a high degree of energy efficiency as a result of comfort (higher surface temperatures, more temperature symmetry), faster heat-up, delayed cool-down – all with a “worse” U-value than the neighboring house.

Since 2015 you can read at www.thermoshield-farben.de: “For the period March 2008 to March 2014 heating costs below 450 € p.a. are proven. Compared to a passive house according to EnEV2009. 30% less heating costs, 20% less construction costs, 50% less maintenance costs.” This contradicts the U-value theory, but this is the practice.

Washing gravel facade 04

Washing gravel facade

Summer and winter thermal insulation

This house is one of the first residential buildings in Rosmalen (Den Bosch, The Netherlands. The solid facade with washed gravel offers little resistance to the penetrating solar heat in summer and during the heating season a lot of heat escapes from the house. In November 2016, the facade was painted with ClimateCoating® ThermoProtect.
The result is satisfactory:
During the cold winter nights, the room temperature almost does not drop, even with the thermostat set lower. In the morning the room temperature is quickly brought to over 20°C. Even if the emirics are not more precise here, this example also shows that ClimateCoating® on the facade is able to keep the heat in the house.

Residential house in Beringe NL 03

Residential house in Beringe (NL)

At the address Hoogstraat 47 in Beringe (L), the homeowner and master painter Thijs Martens coated the roof tiles in black and the façade in white in 2016. Consumption values for heating energy are not yet available, but there are initial experiences: “The uninsulated attic is no longer so very cold in winter” and “Our heating only needs 30 minutes to go from 17°C to 20°C when we arrive home. Before ClimateCoating® it took 1.5 hours”. The exterior walls are a double-shell construction with air gap and so-called half bricks as clinker shell. The significantly shorter heating times and slower cooling down have an energy-saving effect.

Three-family house in Zeuthen 01

Three-family house in Zeuthen

The combination of an ETICS made of wood fibre insulation with ClimateCoating® created a comfortable climate and efficiency.

It started with a home inspection in mid-February 2010. In the context of the house purchase consultation by the expert of the house clinic® the house (built in 1936) was examined from the cellar to the roof. “Something can be made of it here,” affirmed the building expert of the house clinic® the owner-to-be in his vision to turn the old house into a three-family house according to modern standards.

In March, the new owner and builder commissioned DIMaGB Bauplanung with the planning services to obtain the building permit. Decisive for him were the DIMaGB building philosophy as well as the building-physical and constructive concepts, which are based on this and on the experience of a quarter of a century in construction.

The client followed the recommendation to upgrade the building envelope as part of the energy modernisation using wood fibre insulation and a coating with reflektive membrane technology. The façade was adapted to the new floor plans and fitted with an ETICS made of wood fibre insulation boards with a final coating of ClimateCoating® ThermoProtect.

The client chose a lightly tinted pastel shade from the colour palette of around 4,000 shades, which harmonises excellently with the dark window profiles and the engraved roof tiles.

Wood fibre insulating materials have decisive advantages over mineral wool and polystyrene: storage and insulating capacity, made from renewable raw materials, low-energy production, no hazardous waste on the facade, fully sorption-capable due to capillary conductivity.

Combining this wood-fibre ETICS with the thermo-ceramic membrane technology ClimateCoating® achieves maximum efficiency and economy. The facade is protected effectively and for a long time against driving rain, UV radiation, summer heat and freeze-thaw cycles. Prevention against the growth of algae and other microorganisms takes place here without fungicides and algaecides.

The infrared reflection (IR) within the membrane causes a reduction of the radiation to the cold sky and through a dew point shift the reduction of the moisture potential. The combination of the ClimateCoating® membrane with the storage and sorption capable substrate has an over-optimal effect.

The Haus-Klinik® expert confirms: “This is currently (2010) the ecological ETICS: energy-saving, sustainable, economical, efficient.” By the way: the three-family house was a multi-generation house.

Apartment house in Kapfenberg 05

Apartment house in Kapfenberg

10% heating energy savings after the facade renovation carried out in 2011, evaluation by the WEG

The apartment block in Kapfenberg, Austria, is a high-rise building (ground floor + 10 floors) with 44 apartments built in 1974. The heating system was district heating (without hot water). The facade area renovated in 2011 with ClimateCoating® ThermoProtect amounts to approx. 4100 m². The specialist company carrying out the work was Fa. HESCHmaler from 8345 Straden.

An analysis of the change in heating energy consumption was carried out in January 2015 by Ing. Franz Windisch and Ing. Herbert Emminger, who belong to the owners’ association. While the heating energy consumption in the 2010/2011 billing period was still 394.6 MWh, it was only 352.8 and 358.9 MWh in the following two billing periods. This corresponds to a reduction in consumption of around 10%.

For an economic comparison, only the additional costs are to be compared; in the comparison with facade insulation, it is the material cost difference to the levelling coat of the ETICS. The savings potential of facade insulation is given by IWO Austria as 22%, by IWO in Germany it is 19%, co2online gGmbH Berlin gives 19% (02.2014) and according to Heizspiegel Germany 2014 it is only 12% (10.2014).

Apartment house in Spremberg 08

Apartment house in Spremberg

This apartment block in 03130 Spremberg, Artur-Becker-Ring 58/60, is a conventional apartment block built in 1927 and comprises 12 residential units with a total living space of 816 m², a gross floor area of around 4,200 m³ and a ridge height of around 13 metres. After standing empty for several years, it was modernised in 1999. The building lies on the north axis with an 8° deviation from the longitudinal axis. During the inspection on 4 November 2005, it was noticeable that no algae or other microorganisms were visible on the façade despite the nearby trees.

The 49 cm brick walls with lime-cement plaster were coated with ClimateCoating® ThermoProtect. The roof slopes and the walls in the attic were coated with ClimateCoating®ThermoPlus. The basement ceiling is an uninsulated solid ceiling (approx. 80 cm above ground level), the roof insulation consists of 4-6 cm of loosely laid mineral wool. There are thermal bridges in the area of the balcony slabs on the courtyard side; there are 12 identical balconies of 6.2 metres each with 12 cm reinforced concrete slabs, which were laid on the exterior walls.

The modernisation to the extent described has proven to be very effective and economical, as no additional façade insulation was required. The property manager: “We don’t normally have such a low utility bill for heating costs. For example, an 8-family house (new build) is more expensive than this 12-family house.” The tenants are very satisfied. Axel T.: “Even in winter, there are only 3 radiators running in the flat, but only on 2-3. A great heating bill.” Mrs B. previously lived in a new-build flat, where she was always cold; she is delighted. Mrs S. is allergic: “Since we’ve been living in a ClimateCoating flat, I feel better. When you walk into a flat like this, you notice the difference between ClimateCoating® and paint.”

In terms of energy efficiency, subjective perceptions are confirmed by low heating bills. In addition, a comparison with the heating bills of neighbouring blocks of flats over a period of 4-5 years shows that the 8 cm thick polystyrene thermal insulation installed in the almost identical new buildings at the time (~1960, block construction with cottage pumice) in conjunction with the insulation of the basement ceiling did not result in any more savings. If the manufacturing costs of façade insulation and a ClimateCoating® coating are also included in the assessment, an excellent cost-benefit ratio is revealed.

Very extensive data was available for the energy consumption analysis: Heating bills over 4 or 5 years, precise regional weather data, extensive building plans (floor plans, sections, views). In addition, the envelope surfaces (roof and dormers, solid exterior walls, plastic windows, basement ceiling) were inspected.

One of the first energy performance certificates was issued in 2006 on the basis of this good data. This certifies a consumption that is 28% below the requirement calculated in accordance with the EnEV. This evaluation from 2005/2006 as well as the history of measuring the k-value (today: U-value) and its use in the calculation for the thermal insulation certificate, in addition to other analyses, provided certainty in the evaluation. A validation was carried out to the effect that 2 independently acting scientific working groups, the FHTW Berlin and the FH Lausitz in Cottbus, came to comparable results.

Test surfaces on garage walls outside show a great quality advantage of ClimateCoating® ThermoProtect

The wall surfaces (west side) between the garage doors were painted about 7 to 8 years ago.

The two wall surfaces on the left are coated with ClimateCoating® Exterior, all others with normal exterior white paint, where mould, algae and fungi are visible, whereas on the walls coated with ClimateCoating® the surface is still without complaint.

Renovation farmhouse in the Netherlands 07

Renovation farmhouse in the Netherlands

Stained walls repainted

This old building in the Netherlands was renovated in 2013 with ClimateCoating® ThermoProtect. The problem here was that due to previous use also as a stable building, the exterior walls had absorbed certain liquids and had become stained. The decision to use ClimateCoating® Exterior was the right one because it prevented the stains from bleeding through without the need for further costly renovation measures.

The facade was last painted with ClimateCoating® ThermoProtect in 2011. Previously required to be repainted annually. Among other things, because of moisture problems and cracks due to traffic. In addition, the façade was equipped with the Schrijver system (ventilation slots).

The Black House in Madrid 01

The Black House in Madrid

Brightness reference value or TSR value: ClimateCoating® also works in black.

The “black house” in Holland has already become a household term: you paint a house black – and there are no cracks, bubbles or other damage. And for years. Since spring 2014, Spain’s capital has been home to the “Black House” of Madrid. The building is located at Calle de Manual Tovar 42 / corner of Calle Salcedo and it houses, among others, the Urban Lab Madrid. Here, approx. 2,000 m² of clinker facade were coated with ClimateCoating® in black – at a time when people were still talking about the brightness value.

But regardless of whether it’s the brightness value or the TSR value (“Total Solar Reflectance”) – ClimateCoating® breaks through traditional thought patterns. You can call it “the white black”, you can leave it alone. Remarkable: a black facade does not necessarily have to mean heating up and destruction if you decide to use ClimateCoating®.

Speaking of the TSR value: ClimateCoating® also reflects the UV part of the solar radiation (SOL = UV + VIS + IR) only to a modest extent, around 10%. Thanks to the hollow ceramic beads, however, this has no effect. Thus, the expert comes to the conclusion that ClimateCoating® is more than just paint. Speaking of color: the 80 window cavities with aluminum cladding were painted in 18 different shades with ClimateCoating®.
