Introduction

In response to the increasing demand for energy efficiency calculations in apartment buildings, the popular web service "Energy Efficiency Assessment Web Service" has expanded its offerings. One Building, a company leading digital transformation in the construction industry, has launched a new version specifically for residential complexes. This updated service provides architects and contractors with a highly efficient solution, all accessible directly online and completely free of charge.

Service Overview

The newly launched service aims to streamline the complex process of energy efficiency calculations for residential complexes. Users can simply upload a PDF of their floor plan, and the advanced AI technology (Google Gemini AI) automatically extracts necessary data. This automation not only speeds up the process but also decreases the chances of human errors involved in manual entry. The service allows architects to visualize the energy calculation results for different unit types, orientations, and floors in real time, thereby addressing the rising costs following the enforcement of energy efficiency standards.

Background and Motivation for Development

Market Trends and Challenges

With changes in regulations set for April 2025 that will mandate energy efficiency compliance for all apartment buildings, the challenges faced by design professionals are significant. The existing approach of using Excel for these calculations has proven to be inefficient, particularly due to the repetitive nature of calculations based on unit types, orientations, and floors.
Further complicating the situation, many design firms face prohibitively high costs from outsourcing calculations or purchasing expensive software necessary for compliance. As a result, small and mid-sized architectural firms are finding themselves under significant financial strain due to these added pressures. The heavy burden of manual processes also leads to wasted time and increased risk for input errors.

Resolving Challenges with Cost-effective Solutions

To address these issues, One Building has adapted its successful non-residential service model to better fit the needs of residential complexes. This includes the offer of powerful features such as AI-based floor plan analysis and integration with a database of actual building materials, all provided at no initial or ongoing cost. This approach enables designers to quickly assess compliance with energy standards and facilitates smooth decision-making from the early stages of designing.

Key Features of the New Service

1. Completely Free Access: All essential functions are available at no cost, allowing unlimited simulations without any financial concern.
2. AI-Powered Floor Plan Analysis: Users can reduce manual data entry by simply uploading floor plan files in various formats, from PDFs to PNGs. The AI extracts vital measurements, helping to eliminate time-consuming input errors.
3. Manufacturer Product Database: The service features a database that includes product specifications from various manufacturers. Designers can select products directly on the interface, automatically populating the required specifications into their calculations, which saves time and eliminates the need for manual data retrieval.
4. Visual Performance Management: The service visually demonstrates the performance specifications of different residential units, clearly showing whether they meet the relevant energy standards, thus simplifying the identification and modification of underperforming units.
5. Excel Integration: The service allows high-level integration with established calculation programs, enabling users to download or upload data in Excel format, maintaining continuity with their current workflows.

Future Developments

As this service continues to expand, One Building plans to enhance its capabilities further by adding additional product datasets, focusing on insulation materials and various equipment specifications. This will enable simulations under a wider array of conditions and help professionals conduct comprehensive energy assessments of apartment buildings early in the design process.

For those interested, an online seminar will be hosted to provide details on the new service and how to utilize it effectively. The webinars are set for July 9 and July 23, 2026, conducted via Zoom. Registration is free and can be done through One Building's website.

With the "Energy Efficiency Assessment Web Service for Residential Complexes," One Building is committed to providing innovative, cost-effective solutions to alleviate the burdens of energy efficiency calculations for architects and contractors alike. The goal is to empower every design professional with cutting-edge tools to facilitate compliance and enhance sustainability in residential project designs.
