Energy and economic optimisation of buildings and projects
At Gesvalt we help developers, owners and project teams to make informed decisions by providing services such as energy and economic optimisation of buildings. Energy optimisation makes it possible to compare design, refurbishment or operational alternatives in order to reduce consumption, improve comfort and prioritise investments with a real impact on energy efficiency. CAPEX and OPEX of the asset.
Our approach focuses on analysing scenarios, reducing uncertainty and prioritising measures that deliver real value from an energy, technical and economic point of view.
What does energy and economic optimisation bring?
The energy optimisation allows for improved building performance and data-driven decision making, reducing technical and economic risk.
Main contributions:
Improving energy efficiency and reducing consumption
Optimisation of energy consumption and operating costs
Identification of measures with higher returns
Reducing uncertainty in decision-making
The service makes it possible to identify which measures actually improve the performance of the building and which ones increase the investment without a proportional return in consumption, comfort or operation.
What does an energy and economic optimisation service include?
Our service combines technical and economic analysis, integrating approaches from the energy audit of buildings with advanced modelling to optimise decisions.
Energy diagnosis of the building and definition of the base scenario
We carry out an energy diagnosis by means of a energy audit of buildings, analysing geometry, use, envelope, installations and loads.
This makes it possible to identify the main drivers of consumption, comfort and cost from the outset.
Comparison of scenarios and energy optimisation measures
We propose different scenarios and alternatives for energy optimisation, evaluating improvement measures such as:
- Passive strategies
- Envelope improvement
- System optimisation
- Integration of renewables
The objective is to compare options before investing and to select the most efficient solutions.
Economic prioritisation of measures: impact on CAPEX and OPEX
We analyse the economic impact of each measure, differentiating between initial investment (CAPEX) and operational costs (OPEX).
This allows:
- Prioritise measures according to return
- Balancing investment and savings
- Make decisions based on economic and technical criteria.
Technical validation and support for the implementation of measures
We validate the selected solutions and accompany the design team in their implementation.
We provide clear deliverables, technical support and coordination to ensure project viability.
When does it make the most sense to apply it?
This service is particularly useful in:
- Preliminary or basic project phase
- Rehabilitation or refurbishment processes
- Operating assets requiring optimisation
It allows action to be taken at the right time to maximise the impact of decisions.
Relationship with sustainability and certifications
Energy and economic optimisation facilitates compliance with sustainability objectives and can support environmental certification processes.
It allows anticipating technical requirements and improving building performance without relying on later adjustments.
Frequently asked questions on energy and economic optimisation
What is energy and economic optimisation of a building?
What is energy and economic optimisation of a building?
It is a process to analyse and compare alternatives to improve the energy and economic performance of a building.
How is it different from an energy audit?
How is it different from an energy audit?
The energy audit analyses the current status, while energy optimisation compares scenarios and defines improvements.
What is the difference between CAPEX and OPEX?
What is the difference between CAPEX and OPEX?
CAPEX is the initial investment and OPEX is the operating costs of the building.
When should this service be applied?
When should this service be applied?
In early design phases, rehabilitation or operating assets.
Which measures have the greatest impact on OPEX?
Which measures have the greatest impact on OPEX?
Improvements in systems, energy efficiency and consumption optimisation.
