The review identifies, for example, weaknesses and deficiencies that may make it difficult to achieve good moisture safety and the requirements of building regulations. The review may also result in a favorable assessment or in initial guidance for improvement and development. In complex cases, suggestions for deeper analysis are provided.

The review is based on our expert knowledge and practical and theoretical experience of building structures, solutions, materials and the indoor environment. If there is a lack of documentation, weaknesses or deficiencies, we usually provide guidance and point out opportunities. We often recommend this type of review before or in combination with moisture calculation. This type of review can also be useful for type approval and certification.

Many traditional constructions do not meet the Swedish National Board of Housing, Building and Planning's building regulations. This is partly because the building regulations have been amended and tightened over the past 15 years, and partly because there is more knowledge about defects and faults that have arisen. In addition, requirements for energy conservation have led to increased insulation, which means that traditional structures have become more exposed to harmful moisture conditions.

The service does not replace moisture safety design or type approval/certification but can be useful for these. 

The review is reported in a written statement together with any appendices. The work is based on expert knowledge, experience and the Swedish National Board of Housing, Building and Planning's building regulations. In cases where it is justified and there are relevant references, research etc, reference is made.

It is often an advantage if drawings, description and documentation of designs, solutions, material descriptions and product data are provided.

The review is delivered in a RISE Statement. The statement is signed by the performer and reviewer. 

The delivery time is normally relatively short, within 2-3 working weeks, especially if the assignment is for one working day. In the case of several days' work, more time may be needed. 

We apply running billing with the current hourly rate as it is often difficult to estimate what emerges. Target price with reconciliation or fixed price is also possible. 

We need to see all the documentation to be reviewed before the start of the assignment in order to guarantee the delivery time.

The order can be placed verbally or in writing, for example by e-mail, including invoicing details and organization number. We will then send you an order confirmation.

Moisture calculation is a method to clarify relatively quickly whether a construction has theoretical conditions to function well. The result of a moisture calculation is often evaluated with mould simulation. A moisture calculation is relatively resource-efficient compared to other methods such as field measurement or laboratory testing.

The constructions used and built must have known properties and functions. Having a moisture and mould simulation performed is an essential part of the theoretical basis needed to demonstrate and verify moisture safety. Calculations can provide a basis for improvements or for screening out poor designs early in the design process.

It is only in the last 15 years that realistic and at the same time user-friendly calculation programs have been available. This means that today's design of structures can contain a more engineering basis. In the past, it was common to use stationary calculations, which could not give very realistic results. 

Today, there are user-friendly calculation programs that can take into account most, but sometimes not all, which is why a deeper understanding of building physics, relevant assumptions of parameters and practical experience of constructions are often required. 

We use the hygrothermal calculation program WUFI (1D or 2D) together with one or more mould models such as WUFI-Bio or the MRD model.

In order to make the calculation as realistic as possible, a detailed description/drawing of the construction or design is needed, and preferably the intended location of the building and type of activity. It is usually an advantage if the maximum permitted moisture condition is available for the constituent products.

We often recommend or apply parametric studies, i.e. taking into account several different conditions, as for example the execution of construction usually varies.

The calculation is presented in a calculation report with result diagrams, used parameters and assumptions etc. The result is commented and assessed based on both simulation results and practical experience. 

For example, the delivery time for a one-dimensional calculation is 2-3 weeks and for a two-dimensional calculation slightly longer.

A one-dimensional calculation with report usually requires 10-15 hours.  Two-dimensional calculation often requires double the working time depending on its complexity and number of materials etc.

Drawings, material data and prerequisites need to be available or can be assumed before calculation. 

To order this service, please send an e-mail or place a verbal order and include your invoicing details and organization number in the order. We will then always send you an order confirmation with a description of the assignment.

Depending on the purpose of the calculation, the calculation may need to be performed according to EN 15026. There is also a Swedish guide for calculations “RäknaF”. 

By increasing the degree of circularity and reuse in your interior, you contribute to the reduction of the climate footprint. Sustainable Interior supports a systematic reduction of the climate impact. A HI label issued by RISE, as an independent third party, shows that your company complies with the requirement criteria of Sustainable Interior.

The Sustainable Interior criteria cover the entire interior of your premises and have been developed to support and contribute to increasing the level of circularity and reuse. Working with Sustainable Interior increases your awareness and competence and equips you for increased sustainability requirements including reporting and accounting. The value a HI label can provide among others is:

• Support for increased legislative and reporting requirements 
• Reduced costs for the interior of your premises
• Promotion of your sustainability work 
• Contribution to sustainability goals; increased value for environment, economy and social factors 
• Increased property value 

By letting RISE, as an independent third party, verify and HI-label your premises, you increase the credibility of your sustainability work. Verification of Sustainable Interior is based on the international standards ISO/IEC 17029:2019 and ISO 14024:2018.

RISE verifies how your company follows and complies with the criteria in Sustainable Interior. A review of documents and interviews with employees are carried out on site at the premises, in order to be able to assess whether the company fulfils the requirement criteria of the Sustainable Interior Criteria Document version 1.0. The criteria have been developed in a project in collaboration with various actors with research as a basis and you can freely access the criteria document, which is published publicly on the DiVA portal and at Hållbar Interiör. When the verification is completed and approved, RISE issues a verification statement and an HI label.

After successful completion of the verification, your company will receive a verification statement and an HI label, showing that the interior of your premises fulfils the requirement criteria of Sustainable Interior.

Förberedelser enligt föreskriven process

We assist you in identifying and utilizing building materials with high reuse potential. By focusing on reuse and reducing waste management, we can collaboratively create a more sustainable and circular building process.

The material inventory aims to support property owners during demolition or renovation when decisions need to be made regarding the further handling of the building’s embedded materials. It also highlights the reuse potential of the existing building. The inventory results can be effectively used for the PBL control plan and developed to specify the building products that can be reused or recycled.

We conduct the inventory based on the building’s history, including previous activities and physical conditions. RISE has expertise in testing building products, conducting damage investigations, and assessing indoor environments. We also have the capability to identify and analyze microbial damage and environmental toxins. This ensures quality-assured handling of the materials. Our material inventory is performed in accordance with current legislation and tailored to your needs. 

The results are compiled into a report that lists building products suitable for reuse and recycling, including estimates of quantities and their locations. We place a strong emphasis on quality assurance, with a focus on environmental and health considerations. 

Heat Pump KEYMARK is a voluntary and independent certification mark for heat pumps and air conditioning units. The certification includes products covered by ecodesign in EU regulations 813/2013, 814/2013 and 206/2012. Products which are intended for space heating, space cooling and domestic hot water heating including combination heaters.

The purpose of the certification is to ensure that heat pumps on the European market meet quality and performance requirements according to EU’s ecodesign regulations. At the same time consumer confidence is built through independent third-party testing and continuous factory production control. 

Through a common certification system within Europe, heat pump manufacturers can easily reach large parts of the European market.

KEYMARK is a quality mark that can be used to access public subsidies in most European countries.

RISE is an accredited and empowered certification body, authorized to certify heat pumps according to Heat Pump KEYMARK. RISE has extensive experience in supporting the heat pump industry and has since the beginning of Heat Pump KEYMARK been an active part in the development of the scheme. 

Some of the key benefits of Heat Pump KEYMARK:

• Unified certification: A single certificate that is accepted across Europe.
• Third-party testing: Heat pumps are tested by independent testing institutes to ensure they meet current requirements.
• Recurring inspections and tests: Regular factory and quality inspections to maintain a high standard.
• Transparency: A transparent system that builds trust among consumers and the market.

The heat pump manufacturer applies for KEYMARK certification to Certification at RISE. Subsequently, a heat pump is selected for an initial test at an independent third-party laboratory. RISE has a cooperation agreement with several European test laboratories. The manufacturer has the possibility to choose test laboratory independently. This increases the flexibility and reduces the risk of long lead times. The test laboratories which have been approved by RISE can be found on the KEYMARK website via the link down below. Tests are conducted according to applicable parts of the European standards: EN 14511, EN 14825, EN 16147, EN 12102, and EN 15879-1. 

Factory Production Control (FPC) is carried out at all manufacturing sites by a RISE-qualified auditor, with a strong focus on the production line and quality system. 

The manufacturer declares performance data according to the above-mentioned European standards in the KEYMARK database for comparison against the test report. The FPC report is also evaluated. Once all relevant documentation has been received and assessed to meet current requirements, a KEYMARK certificate can finally be issued.

The certificate is published on RISE website as well as in the KEYMARK database of certified heat pumps. A certificate is issued with a validity period of 10 years. After that, the certificate can be renewed. The validity assumes that the certified heat pump continuously placed on the market meets the requirements and that the manufacturers system for self-inspection is continuously reviewed and assessed according to an established plan. 

The certificate holder can label their heat pump with the KEYMARK logo along with the applicable certificate number. The holder can refer to the certificate and show that the product has been tested and certified by a third party.
