nZEB Residential Design Guide

20 February 2025

In the heart of Bucharest, where history intertwines with modernity, a visionary project was set to redefine urban living. Mosaic Residence, renowned for its innovative developments in Brașov, where it has completed and handed over 355 apartments, embarked on its inaugural residential venture in the capital. This ambitious project aimed to introduce a new standard of luxury and sustainability to Bucharest’s skyline.

To bring this vision to life, Mosaic Residence Bucharest collaborated with Mihaela Oroian, a real estate professional with over two decades of experience in the industry. Mihaela’s expertise in urbanism and real estate development, complemented by her commitment to sustainable building practices, made her the ideal partner for this endeavor. One of the standout features of this development was its commitment to sustainability, being nZEB certified, according to law 372/2005 republished in 2020. Designing an nZEB (nearly Zero Energy Building) residential project involves strategic planning to maximize energy efficiency, integrate renewable energy, and ensure long-term sustainability.

Here’s how the project was tackled in 5 steps:

1. Analyze the opportunity:
● Market demand for energy-efficient residential buildings
● EU & local regulations requiring nZEB compliance
● Financial incentives and subsidies available
● Growing consumer interest in sustainable living

2. Set the Key Objectives:
● Minimize energy consumption
● Maximize renewable energy use
● Ensure long-term cost savings and ROI

3. Summarize The Site & Feasibility Analysis
● Project location & key advantages
● Site conditions & solar orientation
● Regulatory compliance & permits
● Financial feasibility: upfront cost vs. long-term gains

4. Implement the following:
● Passive Design Strategies
● Energy-Efficient Systems
● Renewable Energy

5. Update the Financial Model & ROI
● Upfront Costs vs. Energy Savings Over Time
● Break-even Period & Long-Term ROI
● Available Incentives, Tax Benefits & Green Financing

Why Invest in This Project?
● High market demand & future-proof design
● Strong ROI with reduced energy costs
● Green financing & government incentives
● Premium property value & consumer appeal

Potential Green Financing & Incentives
● EU & National Grants: Covers up to 30-50% of additional costs
● Tax Reductions: Lower property taxes for certified green homes
● Green Mortgages: Lower interest rates for energy-efficient properties
● Net Metering: Savings from selling excess energy back to the grid

Long-Term ROI
● 25-50% Higher Resale Value due to green certification
● Up to 90% Reduction in Energy Bills
● More Attractive for Rental Market (Airbnb, Long-Term Renters)

The collaboration between Mosaic Residence and Mihaela Oroian resulted in a residential space that not only met the demands of modern city life but also anticipated the future needs of its inhabitants. This development set a new benchmark for residential projects in Bucharest, exemplifying how thoughtful design and strategic partnerships can create spaces that resonate with both functionality and beauty.

The success of this inaugural project will pave the way for further developments, solidifying Mosaic Residence’s reputation as a trailblazer in the Romanian real estate market. For Mihaela Oroian, the delivery of the first project for Mosaic Residence in Bucharest (scheduled for Q4 2025) is another testament to her unwavering commitment to excellence and her vision of creating spaces that truly benefit the community.

The rising energy costs are stimulating innovation and increasing demand for nZEB and especially ZEB-compliant housing. In a previous material published by Romania Insider, “Real estate investment – The Impact of the potential S&P downgrade of Romania to Junk Status in 2025”, Mihaela recommended the focus on Green Certified Buildings as future-proof homes contributing to decarbonization benefiting of low tax and energy price efficiency.
