Design memo of 300 to 500 words: your strategy and why, what the loads told you about your envelope, where your structure got in the way, and what you left unresolved
The Berkeley site sits three blocks from campus in a marine Mediterranean climate. Oakland weather data shows average afternoon temperatures running from the mid-50s in winter to about 70°F in late summer, with overnight lows in the 40s and 50s and rare hot spells above 80°F. Very few hours need mechanical cooling: the 75th percentile temperature is 62°F, and only 1 percent of hours exceed 79°F [Clima, Oakland station]. We cut loads first with a 32 percent window to wall ratio, balconies that shade the windows below them, and an insulated wood-frame envelope. Apartments open their windows in mild weather. When smoke, noise, or cold keep windows shut, we choose an in-unit balanced energy recovery ventilator to supply filtered fresh air, which also meets the 2025 California Energy Code rule against exhaust-only ventilation in new units. In-unit ducted heat pumps with roof condensers supply heating and occasional cooling, and heat pump water heaters supply domestic hot water, which follows the 2025 code’s heat pump baseline and lets each tenant pay for their own energy. Ducts run from a closet in each unit through corridor soffits to ceiling diffusers, which costs us corridor ceiling height. Each apartment is one zone, except corner units, which we split by orientation. Corridors, the lobby, and retail form separate zones. We have not yet resolved how the roof condensers and the solar panels the code may require will share roof area.
