Customized sustainability consulting
What will characterize buildings in the future? They will take into account the needs of people as well as environmental and economic requirements. Connectivity, flexibility, circularity, energy efficiency and emissions reduction all play an important role. The key is to take an integrated approach to these requirements and align them with the economic objectives of the property.
Drees & Sommer Switzerland is an expert in the field of sustainability consulting and green building certification and is your partner for all aspects of life cycle engineering. Our experienced consultants and project managers support you from the initial idea through to commissioning. We evaluate your property and its use from an economic, technical and ecological point of view, identify potential savings and optimization opportunities, and develop specific strategies and measures.
The aim of our sustainability consulting is to balance environmental, economic and social requirements. Together with our clients, we develop solutions that take sustainability goals into account while keeping the economic framework of the property in view.
Our solutions for sustainability, ESG, and the circular economy
ESG consultation
ESG (environmental, social, governance) takes into account environmental, social and corporate governance criteria in addition to economic factors. Systematically recording and assessing these factors creates transparency around risks and opportunities and provides a basis for long-term corporate and real estate strategies. Drees & Sommer Switzerland is guided by ESG regulations and supports clients in introducing and complying with them. The result is a concrete strategy and plan of measures that is tailored to your needs.

Cradle to cradle and urban mining
The Cradle to Cradle® (C2C) concept describes the principle of continuous biological and technical cycles within the circular economy. The targeted use of circular and low-pollutant materials can help improve material health and the circularity of buildings while keeping resources in circulation over the long term. Drees & Sommer Switzerland advises you on all issues relating to the implementation of the circular economy, be it the handling of raw materials, the purchase or leasing of circular building products, the furnishing of your property, the dismantling of your site/property, or the analysis of buildings for their circularity.

Portfolio management – a clear strategy toward net zero
We conduct a comprehensive portfolio analysis to determine economic potential as well as opportunities to reduce energy consumption and carbon emissions. Together with you, we develop a net-zero strategy tailored to your goals, identify synergies within the portfolio and define specific measures. From strategy to the implementation of individual structural measures, we support you during planning, quality assurance and execution right through to commissioning. At the same time, we show you which innovative supplementary technologies are suitable for your property and develop a roadmap for energy-efficient renovation.

Green building certifications
For green building certification, our experts determine the appropriate green building label for your project (Minergie/ECO/P; LEED; BREEAM; SNBS; DGNB; and SSREI at portfolio level) and review the costs, opportunities and risks of the project. We support the certification process and are authorized to certify buildings in accordance with these established systems. This makes defined sustainability criteria for your property transparent and provides a clear basis for investors, users and other stakeholders.

Life cycle Engineering
Our life cycle engineering examines and evaluates properties and their use in terms of economic, technical and environmental factors and develops economic optimization strategies. Our technical and economic construction consultancy supports you in keeping the defined project objectives as well as the planned schedule and budget in view.
360° property assessment Analysis
This is an extension of the regular TDD, in which we advise you based on an analysis of other technical areas such as smart buildings, electromobility and net zero, as well as important areas such as social issues and governance. This provides you with a comprehensive basis for decision-making to systematically pursue your sustainability goals and identify relevant risks at an early stage.
Sustainability requirements are increasing. Turn them into an opportunity.
Growing sustainability and ESG requirements, regulatory frameworks such as the EU Taxonomy and green building standards present investors and building owners with new challenges. Alongside economic performance, measurable environmental and social criteria, regulatory compliance and the long-term future readiness of real estate are becoming increasingly important.
The question is not if you should act, but how.
Build a holistic strategy. Start with legal analysis, implement concepts and solutions, and manage regulatory complexity. This can help identify economic potential and prepare buildings for future sustainability requirements.
Failing to address relevant sustainability and ESG requirements at an early stage can expose properties to regulatory, economic and technical risks. Depending on the property and market, this may result in disadvantages in leasing, sales or valuation, as well as additional refurbishment and investment requirements.
By defining sustainability goals at the start of the project and integrating them into planning and decision-making processes. Criteria such as circularity, energy efficiency and carbon reduction can be considered alongside regulatory requirements, life cycle costs and the long-term usability of the property.
Let's talk.
We look forward to hearing from you!
