     <h3>Mechanical system design and project management.</h3>
     <p>Mechanical and electrical design, hardware specification, and project management of the building-wide HVAC plant serving the general building and all five tenants. Designed, built, installed, and wired in partnership with our plumbing and electrical trades, with us as the integrator from the first sketch through commissioning.</p>
+    <p>Design features include:</p>
+    <ul>
+      <li><b>Room-temperature, medium-pressure heat-transfer loop.</b> No insulation required, minimal-cost piping &mdash; unmatched buildout cost.</li>
+      <li><b>Hyper-efficient water-source heat pumps</b> with EERs of 24 to 28.</li>
+      <li><b>Variable-speed pump arrays</b> for minimal energy operation across load conditions.</li>
+      <li><b>100% heat recovery</b> between heating and cooling loads.</li>
+      <li><b>High-efficiency heat rejection</b> through evaporative cooling.</li>
+      <li><b>Optimal use of the building's natural thermal mass</b> &mdash; 18&ndash;24" brick walls, both exterior and many interior partitions.</li>
+      <li><b>Fully modular and expandable.</b> Built for unlimited expansion with low-cost additions and reconfiguration.</li>

     <h3>Control system design and implementation.</h3>
     <p>We specified the control hardware, drew the wiring, and built the panel. Industrial breakers and contactors on the power side; I/O modules addressing the sensor and actuator network; a Raspberry-Pi-based supervisor bridged to the rest over Modbus. The supervisor hosts the agentic control software directly. The agents handle several distinct jobs:</p>
