reduction through our solutions
The energy transition is one of the ways in which SPG adds value. By reducing your property’s environmental footprint, you add to its market appeal and ensure its future. A building that consumes less equals an appreciating portfolio. The possibilities are endless.


Reinvent the present for a sustainable future
Faced with a climate emergency and evolving standards, renovating a building means more than simple maintenance: it requires transformation to keep the building relevant, performing and attractive going forward. That means thinking about extensions, elevation and taking account of these profit-enhancing opportunities.
SPG meets this challenge by reconciling densification, quality of life, regulatory requirements and environmental goals, to make a new promise with each renovation.


New projects with lofty environmental ambitions
Energy performance, positive energy building, certifications… Whether the THPE (very high environmental performance), Minergie, Minergie P or Minergie P Eco, SPG’s property developers include these ambitious goals at the heart of their daily mission, rigorously managing new projects undergoing development.
Coordinated expertise to bring out the beauty of your property portfolio
Our team is with you, applying its targeted expertise at every stage of your energy positioning project: the transition to sustainable development aspects, the first survey through to completion. By applying a tailored approach, we optimise the positioning of projects under development through new operations, but also by working with existing stock. Our roots in the Lake Geneva region and our expertise in the sector facilitate the acceptance of your project by the local authorities and maximise your prospects of completion within the best possible time.
Strategic advice and global management
Whether for a renovation project or real estate development, we define an energy strategy adapted to your portfolio, always based on economic and financial feasibility. We accompany you throughout the process: feasibility study, approaches to the local authorities, mobilisation of financing and coordination of completion stages.
Rigorous environmental and technical follow-up
We ensure continuous quality control and conformity of your development or energy renovation project with the best environmental practices. This follow-up enables attainment of the most exacting certifications, while at the same time ensuring coherence between your goals and the reality on the ground.
AMOen: guarantee of energy excellence
We integrate performing technical solutions into our projects through our Energy Project Management Assistance (AMOen) service: thermal insulation, production of local renewable energy (thermal solar panels, heat pump, etc.), optimisation of the heating and ventilation systems.
The aim: minimise consumption.
PMA: involve users to achieve a sustainable impact
As a building is also a harmonious living environment, we offer Usability Assistance (UA). This makes people living in buildings more amenable to changes in their living environment, through supporting them the first time they use something new and by encouraging their acquisition of energy-saving devices.
