Instead of relying on the builder&amp;rsquo;s specifications or energy certificates alone, we took a different approach: &lt;strong&gt;we instrumented the house with sensors, recorded months of real data, and built a physics-based thermal model calibrated against actual indoor temperatures.&lt;/strong&gt;&lt;/p&gt;</description></item></channel></rss>
