This　article　discusses　the　impact　of　urban　layout　on　the　energy　performance　of　residential　buildings.　A　comparative　analysis　of　multiple　variants　of　land　development　differing　in　building　layout　only,　with　all　other　features　being　the　same,　including　the　building　envelope　properties　and　technical　equipment,　was　carried　out.　The　research　was　conducted　in　two　selected　locations　in　Poznan　metropolitan　area　(Poland),　which　is　located　in　the　Dfb　climate　zone　(humid　continental-warm　summer　subtype).　For　each　location,　the　following　variants　of　building　layout　were　considered:　parallel　buildings　(12　variants　with　an　orientation　towards　the　sides　of　the　world　rotated　in　steps　of　15　degrees),　perimeter　frontage　buildings,　and　comb-shaped　buildings　with　semi-open　courtyards　(4　variants　with　courtyards　open　to　each　side　of　the　world).　The　calculation　of　annual　end　uses　for　heating　and　cooling　was　conducted　as　well　as　the　peak　values.　All　calculations　were　performed　using　OpenStudio　Application　Release　v.　1.2.1　software　with　the　SketchUp　plugin.　The　results　showed　that　the　proper　arrangement　of　buildings　on　the　urban　plot　may　result　in　significant　energy　savings.　The　considered　variants　differed　in　terms　of　annual　end　uses　for　heating　and　cooling　even　by　approx.　15%,　and　the　peak　values　on　the　hottest　days　were　4-10　times　lower　in　comparison　with　the　least　advantageous　variants.　The　results　show　the　slight　advantage　of　compact　development　over　free-standing　development　in　terms　of　total　end　uses　as　well　as　the　south　and　north　orientation　of　facades　over　the　east　and　west　in　terms　of　peak　solar　heat　gain　values.
