The challenge facing architects is no longer simply how to reduce operational carbon, but how to ensure buildings remain comfortable, healthy and productive throughout their lifetime
temperatures above 70°C has historically been a constraint on full heat pump specifi cation in commercial projects, but advances in refrigerant technology such as the development of high-temperature heat pump products have largely resolved this. Several design considerations are non- negotiable, beginning with a fabric-fi rst approach. The lower fl ow temperatures at which heat pumps operate make building envelope performance a critical variable, not a secondary concern. Electrical infrastructure must be assessed early as heat pumps increase demand signifi cantly, and engagement with the Distribution Network Operator should happen at the earliest possible design stage to avoid abortive work. Plant footprint, noise and the risk of cold air recirculation from air-source discharge must be resolved in the layout. For offi ces, hotels, retail and education buildings, Variable Refrigerant Volume (VRV) air-to-air heat pump systems offer a practical and effi cient route to integrated heating and cooling in new builds. Direct expansion systems respond immediately to changing indoor conditions, a compelling advantage in buildings where solar gain, occupancy and IT loads can shift rapidly.
New look column radiators from Stelrad
Stelrad Radiators has introduced an Italian designed new look, improved range of its popular Column radiators – in both its vertical and horizontal column radiator ranges. With effect since 01 July 2026, the new range is available through all existing outlets streamlining the existing range, enhancing the performance from its Column
radiator selection, and strengthening long-term value for purchasers of the range. The most obvious changes are to the design of the radiators that will now feature a new rounded column design.

Heat recovery confi gurations allow simultaneous heating and cooling in different zones, recapturing rejected energy and redistributing it where needed. Compact refrigerant pipework and a self- contained installation make VRV systems straightforward to integrate structurally, and the industry’s ongoing shift towards lower GWP refrigerants like R-32 makes them particularly suited for projects seeking BREEAM, LEED or WELL. As temperatures continue to rise, the challenge facing architects is no longer simply how to reduce operational carbon, but how to ensure buildings remain comfortable, healthy and productive throughout their lifetime. Thermal resilience and decarbonisation should be viewed as complementary objectives rather than competing priorities. By considering building fabric, mechanical systems and electrical infrastructure as part of a unifi ed design strategy from the earliest project stages, commercial buildings can offer resilience and support the transition to a lower-carbon built environment.

HLM Architects has completed a new studio environment in Cardiff featuring a coordinated fl ooring specifi cation from Gerfl or, designed to support the demands of a growing architectural practice. The project incorporated 330 m2 of fl oor fi nishes, combining Gerfl or Creation 55 Looselay LVT with Gradus Lunar carpet tiles across circulation areas, meeting rooms and breakout spaces. Relocating to larger premises to accommodate continued business growth, HLM required a durable and adaptable workspace capable of supporting both collaborative and focused working environments. The fl ooring specifi cation needed to balance long-term performance with a cohesive interior fi nish suitable for a busy, design-led studio. Gerfl or Creation 55 Looselay LVT was selected for high-traffi c circulation routes, providing a durable and fl exible fl ooring solution with simplifi ed installation and future adaptability benefi ts. Gradus Lunar carpet tiles were specifi ed within meeting rooms and informal breakout areas to improve acoustic comfort and create a softer underfoot experience.
