Signa-Terre for sure

Validating trust in monitoring and rating energy efficiency in buildings. We assessed the assessors.

The most trusted solution for rating energy efficiency of Swiss buildings

The Swiss real estate business must, as mandated by law, achieve substantial
improvement in building efficiency in very few years. Renovations on existing buildings to reach these goals would cost billions, which brings us to Signa-Terre. Their mission is to help prevent actual or suspected greenwashing in the real estate sector.

Real estate funds use data from Signa-Terre’s ImmoLabel® on their fact sheets, which
require validation by independent assurance that the building efficiency information is
correct. Signa-Terre is a critical link in a chain of trust from supply and construction to
operation and maintenance to investors and residents of buildings in Switzerland – their information must be reliable.

Enter PwC Switzerland. In addition to our profound understanding of controls, we now
have in-house know-how of Swiss Society of Engineers and Architects (SIA) standards to assess multiple data sources, which were of varying quality. Only once we understood the highly complex interdependencies of the sources could we adequately design and implement controls to ensure the quality and reliability of the data that feeds the fact sheets and energy ratings. With PwC Switzerland as independent auditor, Signa-Terre has released its ISAE 3402 type 1 assurance report. We are proud of the small but important role we play in a complex chain of trust in this highly relevant area of the Swiss economy. For sure.
