Ideally we would like to install an AC unit, the building is of solid wall construction, single glazed windows, air tightness is probably poor. Without spending loads on insulation etc as we are only renting, what are our air conditioning and heating options?

I'd estimate the volume of the shop including the cellar to be 385m3

Just moving fresh air with large extractor fans at the back of the shop and air inlets at the front will help a lot. You need a way to seal up the extractors and air inlet when running the AC or heating.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239585#Comment_239585 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239585#Comment_239585 Wed, 27 Apr 2016 15:59:50 +0100 Nick Parsons http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239586#Comment_239586 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239586#Comment_239586 Wed, 27 Apr 2016 16:09:34 +0100 Victorianeco
I appreciate in an ideal world the building would be insulated but not sure how much that would cost, certainly not willing to use our money in a rental property.

What split heat pump would you recommend? I assume I'd need to do a full heat loss calculation first?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239594#Comment_239594 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=14218&Focus=239594#Comment_239594 Wed, 27 Apr 2016 19:57:25 +0100 Mike (Up North) I helped with similar recently for a shop, it was a Mitsubishi Zen 2.5 Kw heat pump split unit. Chosen mainly for looking nice (if that's possible) rather than the spec. Works fine, Was quick to install through to an outer area (check planning if outside unit visible). No problems with it.
Main problem with retail / shops is frontage is not double glazed and generally the buildings are un-insulated and maintained poorly. This particular place has very bright sunlight so from freezing in the morning the temp would rocket as soon as the sun came over the office opposite. Unit seems to cope well this.
Mind you staff still think the only setting is 31 deg but that usual.

Got another shop to kit out, any links for decent kit perhaps at trade price?

I think now you have to be f-gas registered to install which defeats the object of being a DIY install]]>
