REAL ESTATE REDEVELOPMENT AND LIGHTING
Greenvest operates as an Energy Service Company and provides turnkey solutions to increase the energy efficiency of buildings. Through diagnostics, we work out the best system solutions, finance the intervention and maintain the systems throughout the contractual period.
LIGHTING
Greenvest has always focused its attention on visual well-being, considering the correct lighting one of the main factors to be enhanced also to ensure energy savings and maximum comfort. Every lighting analysis and design is carried out with care, aimed at the type of room to be lit.
Our design solutions are flexible, choosing the best in terms of efficiency and effectiveness. And we translate this into economic benefits for customers with predefined and certified energy savings.
AIR CONDITIONING
Greenvest researches excellent solutions to improve indoor environmental comfort in buildings, ensuring high levels of efficiency in the optimal operation of heating and cooling systems. This generates important improvements in terms of energy savings.
Our technicians specialise in the design and construction of suitable solutions for air treatment systems in the field of civil and industrial air conditioning. This avoids exposure to pollutants, defined as VOCs (Volatile Organic Compounds), and disturbances in the workplace or residence related to poor indoor air quality. Our interventions are preceded by thorough air quality examinations with qualified personnel and specific instrumentation.
BUILDING ENVELOPE
Upgrading a building envelope means analysing how the building heats, how it breathes, and what kind of requirements are related to its energy improvement. After a thorough analysis of the real estate site, we propose an integrated design that guarantees truly functional and feasible solutions. In particular, passive systems are used, i.e. capable of decreasing the heat demand upstream and ensuring less energy loss. For example, buildings can be insulated, always with a view to lowering the structure’s heat demand, or windows and doors can be upgraded, up to and including replacement, to prevent heat loss. This also applies to glass and elements in contact between heated and unheated rooms, such as doors and gates.
This work is closely linked with plant engineering to achieve the ideal solution for improving the energy efficiency of buildings through two actions:
- Reducing heat loss
- Making heat supply systems more efficient.
Finally, we try to understand how much energy saving we can also guarantee based on regulatory requirements, by configuring special software that indicates performance values. This is how we achieve thermal comfort and energy savings, using materials that comply with CAM criteria (minimum environmental criteria).
ENERGY PRODUCTION
The redevelopment of a building also includes solutions for green energy production, with a focus on photovoltaics.
We can design and implement every phase of the construction of a photovoltaic and wind power plant, ranging from the feasibility study and business plan to the construction and installation of the plant components.
We also take care of the operation and maintenance of these plants (O & M Operation and maintenance), with constant monitoring and reporting, providing customers with comprehensive periodic reports to monitor performance and benefits.
SEISMIC ADAPTATION
Seismic upgrades consist of defining the degree of age, wear and tear and resistance of a building. Localised or global interventions aimed at reducing the so-called seismic risk are then identified.
An in-depth study is indispensable to define the actual status of the structure, to know the materials, to define the elements of vulnerability, to know its initial level of safety and to establish what level of safety should be achieved through the execution of the project works.
A due diligence of the building is then carried out, a tool for an overall assessment to understand the “health” status of the property.
Once the real situation of the site has been defined, the appropriate technical solutions are identified in order to proceed with adaptation work, with the aim of achieving the safety levels required by the NTC 2008 (Technical Standards for Construction), i.e. to achieve a resistance equal to that of a new building.
The interventions include the consolidation of the structure and the adaptation of the plant engineering.
BMS (Building Management System)
In its energy efficiency-oriented business, Greenvest makes use of Building Management Systems.
The BMS is a computerised, intelligent system consisting of electronic devices designed to monitor and control the different sub-systems of a building.
Through the use of efficient technologies, this leads to the correct and profitable management of installations through control, automation, regulation and supervision.
Plant management with BMS allows real-time measurement of its operation and is functional for pre- and post-intervention control.
It also allows the continuous collection, processing and interpretation of all quantitative and qualitative information acquired through the instrumentation used.
The correlation of the acquired data results in an in-depth analysis, which generates further information for the study of energy efficiency measures to be proposed.
The BMS control system then provides information on the quantity and quality of a system’s consumption (electrical, thermal, water, lighting, etc.) and takes action to eliminate energy wastage.
MONITORING
An energy monitoring system is a plant-integrated tool for checking consumption and parameters to understand the technical status of a system/plant (ventilation, electrical, etc.). It is able to provide, both qualitatively and quantitatively, the exact consumption parameters of the analysed facility, collecting consumption data, in real time or at defined intervals, of each energy vector used (general utilities) and of the specific utilities comprising them. Through this system, it is also possible to continuously define and calculate KPIs (Key Performance Indicators), i.e. energy performance indices characteristic of the monitored facility or process.
When it comes to optimising the energy consumption of facilities with significant energy costs or multi-site businesses, which have, for example, a large number of meters in their name, our technicians check energy bills with “UTILITY CHECKUP”. It is a tool for checking these bills that, using special software with OCR (Optical Character Recognition) technology, digitises the data on the energy bills and carries out a check between the amounts billed by the supplier and the tariffs stipulated in the supply contract and by the Authority. In addition, it allows analyses of costs (also in relation to the main energy market indicators) and energy consumption (e.g. by comparing related sites using a “tag” system).
