3. Throughout the past 7 years, I was tasked with
a few challenges:
improving my family
house sustainability,
reaching the target of
passive house, reducing
existing operating costs
and realising an income.
3. The challenge
Andrea Rosato
MSc in Civil-Hydraulic Engineering

4. I made significant renovations
focusing my attention on
upgrading its
energy balance
(electricity and gas).
4. The concept

MSc in Civil-Hydraulic Engineering

5. 5. The solution
I achieved the goal installing:
 a photovoltaic system (9.45 kWp),
 a solar thermal system (for summer hot water demand),
 a heat pump system (as a heating system) and
 a heat pump system (for winter hot water demand),
gradually switching all the existing systems in electric ones.

6. 6. The outcome
Here I am 7 years later, and I have allowed realising a substantial,
immediate, positive impact upon the followings aspects:
 family economy (free electricity availability, annual income
coming from selling electricity and considerable savings
coming from free hot water availability),
 lifestyle (more comfortable habits),
 the environment (healthier local area, obtained reducing CO₂
emissions coming from burning fossil fuels);
all this preserving and improving the visual harmony of the
internal and external design of the house.

8. 8. ROI
A long-term investment (60% ROI) planned basing the
accountability over a period of time of 20 years, personally
supervised through
• monthly energy production/usage analysis and
• quarterly economic balance.

26. 26. The team
Obviously, I have implemented the plan working along with
a multi-disciplinary team composed of successful
professionals:
• an Architect,
• Mechanical and Electrical Engineers,
• Electricians,
• an Accountant and
• other dedicated professionals.
